Description

  The present invention relates to an address color system, a coding method, a decoding method, and an encryption method using color photographic images for information distribution and the like.

  Data and information (programs) such as documents, characters, figures, mathematical expressions, images, and voices handled by a computer and its peripheral devices, various devices related to computers, or a computer system comprising a plurality of computers connected by communication lines Etc.) are called “computer objects”. For such computer objects, recognizable languages, diagrams, paintings, and the like are normally used in a conventional computer or the like. In other words, the “normal state” of this use means that if the data of the language or the like is always obtained, the contents can be recognized directly and immediately. The same applies to recording, reproduction, compression, etc. of computer objects in a computer or the like.

  Even in information distribution related to computer objects between computers via a communication line such as the Internet, there is a tendency that information distribution is performed as described above.

  In the above-described system such as a computer, information leakage or theft is likely to occur by an unrelated person.

  Therefore, conventionally, in order to prevent the above information leakage and theft, a technique for performing an encryption process has been proposed in order to make it impossible to directly recognize the contents of the information or the like (for example, Patent Document 1). .

  In addition, the present applicant has previously proposed an invention relating to “expression of computer objects using color” (Patent Document 2). The present invention is a technique for expressing data or information handled inside a computer or handled via a computer by using color (color) with an expression means such as a color dot. When necessary data or information (a computer object or simply an object) is recorded in a narrow portion on the surface of paper or the like, it is expressed by color dots or the like. As a result, a large amount of data can be expressed with simple notation. The invention also refers to a method of creating a cipher using color.

  In recent years, color photographic images (or color images) are often used as information to be distributed and transmitted from an information distribution side computer to an information reception side computer via the Internet or the like. Color photographic images are useful as a medium for providing information.

  In recent years, for example, when information is distributed from a server or the like to another PC terminal or the like via the Internet, information distributed on the Internet may be stolen. If the information remains in a normal state as a computer object, the information content can be easily wiretapped. It is required to encrypt computer objects in information distribution between computers via a communication line such as the Internet and realize complete secrecy of data and the like handled in information distribution.

  Furthermore, when a color photographic image is distributed using a PC (Personal Computer) terminal or the like via the Internet, there is a demand for embedding a message other than the image content in the color photographic image. This is in line with the desire to send the necessary information in an encrypted format.

  Further, even a color photographic image is not expressed in full-color colors, but may be a color photographic image with a small color change width and a small number of colors, such as a landscape painting. Even in such a color photographic image, it is desired to perform allocation processing using a color reduced to a desired predetermined number (for example, 65,536) to enable allocation of the predetermined number of objects.

SUMMARY OF THE INVENTION In view of the above problems, both when suggest the best color concept encoding and decoding, information delivery, etc. between computers via the communication line such as the Internet in a computer such as a PC, color Ki allowed to send the messages cryptographically when delivering photographic images, further address the color system, a color photograph can be color change width perform object allocation even with a small color photographic images smaller number of colors An object is to provide an encoding method, a decoding method, and an encryption method using an image.

Means for creating a color with position number (hereinafter referred to as “ address color (Cn) ”) by means of the color (C) to be encoded, and means for encoding a file handled by the computer using a plurality of address colors (Cn) It is characterized by having .
Hereafter, the color of the color code table handled on the computer and the color used as the object of the computer object is referred to as “virtual color”, and an arbitrary color table composed of such color is referred to as “virtual color sheet”. I will call it.

The present invention has the following effects.
First, according to the address color system of the present invention, a part or all of a plurality of pixels of a two-dimensional array forming a display screen for displaying an arbitrary color photographic image is extracted, and pixel position information is obtained for each pixel. to the number (n) granted under, in combination with color (C) represented by the pixel by creating a well of that of "address color (Cn)", the color information and the pixel of the pixel Even if the position information is combined and the colors are the same, these colors can be distinguished as address colors, and a large amount of information can be encoded / decoded using these address colors.
Second, according to the address color system of the present invention, even when the number of colors obtained from a color photographic image is small, even if the same color is obtained by combining the color information of the pixel and the position information of the pixel, Colors can be distinguished as address colors, and a large amount of information can be encoded / decoded using these address colors.
Third, an address color list is created based on a two-dimensional array of pixels based on a color photographic image using the address color system created using a color photographic image. Is used to create an ONC correspondence table and perform encoding or decoding based on the ONC correspondence table. For example, even if a color photographic image transmitted over the Internet or the like is associated with an object, It contains no information about the object, and the encryption effect that it cannot be decrypted is exhibited.
Fourth, using the above-described address color system created using color photographic images, using a predetermined number of colors created using color photographic images, appropriately subtracted from the full color number, and color A two-dimensional array of pixels of a photographic image is divided, and one section is cut out from the divided pixels to create an address color list. Using this address color list and object list, an ONC correspondence table is created, and the ONC Since encoding or decoding is performed based on the correspondence table, even if a color photographic image transmitted over the Internet or the like is associated with an object, it does not contain any information about the object and cannot be decoded. The encryption effect is possible.
Fifth, since the address color system technology is used, even if a color photograph image with a small color change width and a small number of colors, such as a landscape painting, is used, it is an effective color for practical use. Photo images can be created.
Sixth, only the ONC correspondence table prepared in advance can decode the color photographic image transmitted from the information distribution side to the information reception side, and the ONC correspondence table is an address based on the object list and the color photographic image. Since it is made based on the color list, even if the transmitted color photographic image (color encryption key) is wiretapped on the Internet, the ONC correspondence table cannot be made without the object list, and the color photographic image The effect that cannot be deciphered is demonstrated.
Note that the object list and the address color list are stored in a recording medium such as a CD-R or USB memory and sent by another route other than the Internet such as mail, so that they are completely disconnected from the Internet and are not wiretapped. .
Seventh, using the color of the image portion of the color photographic image transmitted from the information distribution side to the information reception side or the image portion drawn in the margin portion, an address color is created and encrypted on the color Message information can be posted. That is, at the information transmission source and the transmission destination, on the basis of the ONC correspondence table (address color list and object list) generated from the color photographic image and the message information, the information transmission side converts the message information to the color code image. The information receiving side receives information from the information distribution side by converting the tally into the ONC correspondence table and encrypting it, and the information receiving side encodes the color photographic image with the ONC correspondence table and reversely converts it into message information. The message information can be transmitted in an encrypted state via the Internet. The address color system technology is also an embodiment of a secret sharing technology for tally division using color photographic images.
Eighth, the combined use of a virtual color sheet and a color photographic image tends to make the identification unstable each time a color change appears due to the nature of the color when the color photographic image is captured. Uniform color issues such as pixel border blur, blur, and image reproduction rate can be solved. Therefore, imaging conditions can be relaxed, and full color can be used by relying on a virtual color sheet. Accordingly, sufficient color entities can be constructed.
Ninth, there is an effect that a full color can be used even with a small amount of color information of a color photographic image.

The ONC correspondence table is a correspondence table of objects (O), color numerical values (C), and colors (C), is created based on color photographic images, and is provided in common on the information distribution side and the information reception side.

  In the above, “color photographic image” means a color photographic image (including a color image) displayed on a display screen of a computer display device, and an arbitrary color photographic image drawn on an arbitrary material such as a book or paper. (Including color images).

  Here, with reference to FIG. 25, an apparatus configuration example will be described in which a color photographic image (color code image) drawn on paper or the like is captured by a camera and input. The paper or the like 111 on which the color photographic image is drawn is illuminated as required by the illumination device 112, and the illuminated paper or the like 111 is imaged by the imaging device (camera) 113. An image signal obtained by imaging by the imaging device is input to the computer 114. The computer 114 includes a CPU 115, a memory (image memory) 116, and a hard disk 117, and includes a display device 118 and an input device 119. A processing program 121 is provided in the hard disk 117. The image signal input to the computer 114 is converted into digital data and stored in a memory (image memory) 116. Data necessary as image data included in the color photographic image is read from display data stored in the memory (image memory) 116 and stored in the hard disk 117 as read data 122. In this way, the color photographic image drawn on the paper 111 or the like is stored in the hard disk 117 of the computer 114.

  In the computer on the information distribution side, the encoding method is performed using the address color system created using the color photographic image, and the color photographic image is transmitted to the computer on the information receiving side.

In the encoding method using a color photographic image on the information distribution side computer and the decoding method using the color photographic image on the information reception side computer, the method according to the present invention uses “address color” as described above. Is used, which will be described later.

  FIG. 1 shows the configuration of an information distribution system to which the present invention is applied. In FIG. 1, the information distributor 12 and the information receiver 13 are in a communicable state via a communication means such as the Internet 11. The state shown in FIG. 1 shows a pre-setting phase.

  The information distributor 12 shown in FIG. 1 includes an information distribution device 14 configured by a computer system, and the information receiver 13 includes an information reception device 15 configured by a computer system. In this information distribution system, an ONC correspondence table 21 (object list 21A and address color list 21B) is created based on the color photographic image 21C.

  The ONC correspondence table 21 created as described above is stored in the storage device 14A of the information distribution device 14 on the information distributor 12 side and the storage device 15A of the information reception device 15 on the information receiver 13 side. . The ONC correspondence table 21 is a correspondence table having a characteristic of associating a computer object (also simply called “object”: O), a color numerical value (N), and a color (C) as a conversion table. Also used.

In the present invention, the color (C) is based on the concept of “address color”. “Address color” means “Position Number Suffixed Color”. In other words, "address color" corresponds to a plurality of color cells selected according to a predetermined standard by dividing the color cell forming the image in the color photographic image described above into areas and using part or all of the color photographic image. This is a specific color obtained as a result of addressing and distinguishing each color for each color cell. The addressing for each color cell is to assign an arbitrary number based on the position information of the color cell. A plurality of identical colors are configured to be distinguished based on the appearance rank number (pixel position number). Hereinafter, the color (C) is referred to as “address color (Cn)”.
The “color cell” is a uniform color unit section composed of a plurality of pixels of one pixel or more, and is particularly referred to as a pixel in the case of one pixel configuration.

  The CPU in each computer system of the information distribution device 14 and the information reception device 15 is based on a predetermined conversion program, between “ON”, “N-Cn (address color)”, or “Cn (address)” When the conversion unit relating to “color) −O” is realized, it is used in the conversion process between each of the computer object (O), the color numerical value (N), and the address color (Cn). With respect to the ONC correspondence table 21, specific examples of the object (O), the color numerical value (N), and the address color (Cn) will be described later.

  As described above, the ONC correspondence table 21 according to the present embodiment is configured based on the object list (NO) 21A, the address color list (NCn) 21B, and the color photographic image 21C. The object list 21A is a list in which the computer object (O) enumerates each of a large number of object elements (or objects: O1, O2,..., On) and describes the contents thereof. The content of the object element is arbitrary, for example, each sentence part (single sentence, phrase, word, etc.) formed by disassembling a long sentence.

  FIG. 4 shows an example of a computer object (text object) expressed by a relatively long sentence. The computer object related to the sentence (text) 28 is a sentence explaining the company regarding the applicant (Tani Electric Industry Co., Ltd.). An object element is generated by appropriately disassembling the sentence 28 shown in FIG. An example of the disassembly method will be described later.

  In this embodiment, the color photographic image 21C is an image drawn in a predetermined number (about 64,000 colors, etc .: 256 × 256 = 65,536) created based on, for example, full color (16,777,216 colors). A specific example of the color photographic image 21C will be described later.

  As shown in FIG. 2, the ONC correspondence table 21 is normally created and prepared on the information distributor 12 side, and sent to the information receiver 13 side. The ONC correspondence table 21 (the object list 21A and the address color list 21B) is the object list 21A and the address color list 21B is a distribution route (RU1) such as mail or home delivery in the form of a recording medium 22 such as a CD-R or a USB memory. ) Is sent to the information receiver. The color photographic image 21C is transmitted as a color code image to the information receiver side via a route (RU2) via the Internet 11. In other words, the color photographic image 21 </ b> C is transmitted, for example, as the color encryption key 23 from the information distribution device 14 of the information distributor 12 to the information reception device 15 of the information receiver 13.

The transmission or movement route of the color photographic image 21C and the ONC correspondence table (object list and address color list) shown in FIGS. 1 and 2 is as follows.
<Transmission path of color photographic image 21C>
[Information Distribution Device 14] → (Transmission) → Color Photo Image → (Reception) → [Information Reception Device 15]
<Movement path of ONC correspondence table>
[Information distributor 12] → (shipping) → ONC correspondence table (object list and address color list) → (reception) → [information receiver 13]

  The color photographic image 21C does not necessarily have to have a special role as a color encryption key. It can be used as a normal color photographic image 21C. According to the technique of the present invention, special information such as a message can be expressed by a normal color photographic image 21C.

  The information receiver 13 combines the ONC correspondence table 21 (object list 21A and address color list 21B) sent by mail or home delivery with the color photographic image 21C sent via the Internet 11. The ONC correspondence table 21 is prepared at hand. As a result, the information receiver 13 can be ready to receive color-encrypted information and the like.

  On the information distributor 12 side, the ONC correspondence table 21 (object list 21A and address color list 21B) paired with the color photographic image 21 sent from the information distributor 12 side to the information receiver 13 side is: It can also be updated regularly.

  Periodic updating is performed based on the original ONC correspondence table 21 and a combination of random number shuffle and color code images. “Random number shuffle” means assigning pseudo random numbers generated by setting initial values of pseudo random numbers by linear congruence method etc. to colors (C1 to Cn) or color numerical values (1 to n) in the ONC correspondence table. The process of randomly changing the order of the color (C1 to Cn) or the color value (1 to n) by rearranging the color (C1 to Cn) or the color value (1 to n) using the pseudo random number as a sort key. Say. The periodic update executed by the information distribution device 14 on the information distributor 12 side is the same initial value (or color code image of the initial value) of the pseudorandom numbers sent from the information distributor 12 side to the information receiver 13 side. The information receiving device 15 on the information receiver 13 side also executes the information using the same pseudo-random number generated based on

  Here, the “linear congruential method” is to add another constant b by multiplying the initial value X0 by a constant a, and then set the remainder obtained by dividing the result by a certain number c as the next random number. If it is a random number sequence, it is calculated by the following formula.

                Xn + 1 = (Xn * a) + b mod c

  This is the pre-setting phase. After that, it becomes the operation phase of information distribution.

  FIG. 3A shows a state diagram of an information distribution operation phase. On the information distribution apparatus 14 side, when there is a text object 24 to be distributed, the address color (Cn), the object (O) 24, and the color numerical value (N) are prepared using the prepared color photographic image 21C (tally 1). Are associated with each other to create the ONC correspondence table 21 (tally 2). The internal structure of the ONC correspondence table 21 is shown in FIG. 3B. In this embodiment, the text object 24 is the sentence (text) 28 shown in FIG. The prepared color photographic image 21C (tally 1) is sent from the information distribution apparatus 14 to the Internet 11. The color photographic image 21C (tally 1) is transmitted to the information receiving device 15 via the Internet 11. As a result, information distribution is performed via the Internet 11. In the information receiving device 15, the transmitted color photographic image 21C (tally 1) is inversely converted using the ONC correspondence table 21 (tally 2) prepared in advance, and the text object (O) 24 is converted. obtain. That is, the address color (Cn) is extracted from the color photographic image 21C (tally 1), and then converted (reversely converted) in the order of Cn → N → O to take out the text object 24. In this way, the text object 24 including the required information content can be distributed from the information distribution device 14 to the information reception device 15. The address color technology is also an implementation form of a secret sharing technology for tally division using color photographic images.

  However, although a color numerical value (N) having a small data capacity may be transmitted instead of the color photograph image 21C instead of the color photograph image 21C, encoding (O → N) / decoding (N → The conversion of O) is still possible.

  In the above-described “preliminary setting phase”, the color photographic image 21 </ b> C transmitted via the Internet 11 is a main part for forming the ONC correspondence table 21. The color photographic image 21C has a function as the “color encryption key (23)” as described above. In the color photographic image 21C, in constructing an “address color system” using the color photographic image 21C, as described later, the RGB three-color color reduction method is typically employed in the present embodiment.

  As another method, a histogram method can be adopted instead of the RGB three-color color reduction method. The histogram method is a method for generating an address color list by arranging colors in descending order based on the frequency distribution state of each color of RGB in a color photographic image.

  In constructing an “address color system” using color photographic images, it is desirable to use the RGB three-color color reduction method, but this is not an essential element.

  Next, referring to FIG. 5 to FIG. 17, a process for performing an RGB three-color reduction method using a color photographic image, creating an address color (address color system), and further encoding the address color is performed. explain.

FIG. 5 shows an example of a color photographic image. The color photographic image 30 is an example of the above-described color photographic image 21C and is actually drawn in full color, but in FIG. 5, for the sake of convenience, the color difference is indicated by diagonal lines on the diagram. FIG. 6 is a diagram showing the color photographic image 30 as a two-dimensional array structure of pixels. Each pixel is drawn with an exaggerated shape. Further, characters (R (red), G (green), and B (blue)) representing colors corresponding to the color photographic image 30 are written on some predetermined pixels.
In addition, when the color of the color pixel (pixel) regarding the color photographic image 30 displayed on the display screen on the computer is a color used in the color code table (ONC table), the color is referred to as “virtual color”.
Further, in the two-dimensional array structure of pixels relating to the color photographic image 30 shown in FIG. 6, it is used to assign an image ID to a specific address color.

FIG. 7A is a flowchart showing a procedure for creating an ONC correspondence table (color encryption key) based on the color photographic image 30 serving as an original image (original image).
The flowchart shown in FIG. 7A is roughly composed of a flow (process) S10 for generating an address color (address color system) and a flow (process) S20 for encoding an address color. A step S1 for preparing text (the sentence 28 described above) and a step S11 for preparing a color photographic image are provided in the preceding stage of the flow S10 for generating an address color. Details of the address color coding flow S20 are shown in FIG. 7B.

  In FIG. 7A, first, a color photographic image 30 is arbitrarily prepared as an original drawing (step S11). This color photographic image 30 depicts one screen of the fairy tale “Momotaro no Kikai”. In FIG. 5, 30a is the main character Momotaro, 30b is a demon, 30c is a dog, and 30d is a spear. As the color photographic image 30, for example, an image displayed on a display screen of a display device of a computer such as a PC is assumed. This color photographic image 30 is a bitmap image, and is made up of a large number of color dots arranged in a two-dimensional plane. Each color dot corresponds to a pixel (color cell) on the display screen.

  FIG. 6 shows an example of a planar image region 31 in which the color photographic image 30 is represented by RGBX. A color photographic image 30 is represented in an image area 31. The image area 31 includes H pixels in the vertical direction (Y direction) and W pixels in the horizontal direction (X direction) with reference to the reference point O at the upper left corner of the image. The image area 31 is formed by H × W pixels 32. Usually, for example, the image data size is 320 (H) × 460 (W) pixels. Each pixel 32 is a color cell and forms a color dot. Actually, each pixel 32 has a minute shape. Each pixel 32 is expressed in full color. The color (C) of each pixel 32 is made up of, for example, a combination of three primary colors of R (red), G (green), and B (blue), and is represented by 3 bytes (24 bits) on the data inside the computer. Is done. Each color of R (red), G (green) and B (blue) is expressed in 256 levels (expressed in 1 byte (2 to the 8th power)), so in the case of full color, it can be expressed in 16,777,216 colors. Is possible.

  In FIG. 6, in the image area 31, colors R, G, and B are shown for each pixel corresponding to the color of each area drawn in the color photographic image 30 shown in FIG. 5. Depending on the content of the image displayed in the color photographic image 30, the colors R, G, B, and one other color (X) are distributed in the image area. FIG. 6 shows an RGBX two-dimensional array and shows a monochromatic image based on a reduction rule described later.

  In the image area 31, the color photographic image 30 drawn in full color is given a color to each of the H × W pixels 32. In the color photographic image drawn in the image area 31, in the case of the narrative color photographic image 30, pixels of the same or similar color are collected for each partial area according to each part of the drawn image. For this reason, when the image area 31 shown in FIG. 6 is scanned as an XY plane, and each pixel 32 is selected from the image area 31 and arranged in a line, for example, the colors of the same color system are arranged together. It will be.

  Color reduction processing is performed on the original color photographic image 30, that is, the image region 31, (step S12). The “color reduction” will be described below. In the case of this embodiment, “color reduction” means that the number of steps (gradation) of each color of RGB that makes up the color of each pixel 32 in the full-color color photographic image 30 shown in FIG. This is to reduce the number of colors used directly to four colors consisting of R (red), G (green), B (blue), and X (any other one color).

  In the method described below, representative colors (colors) of color reduction are not limited to the above three colors of RGB, but may be, for example, three colors of CMY (cyan, magenta, yellow), In addition, there may be three typical colors that are easy to group the color classification of the color photographic image.

An example of a rule for performing color reduction processing is shown below.
R color = {(r, g, b): | (r, g, b) − (255, 0, 0) | ≦ 50} (single R color)
G color = {(r, g, b): | (r, g, b) − (0, 255, 0) | ≦ 50} (G single color)
B color = {(r, g, b): | (r, g, b) − (0, 0, 255) | ≦ 50} (B single color)
X color = {other colors} (gray color)

  According to the above rule, first, an element belonging to the color set of R (red) is R whose absolute value is 50 or less by obtaining a difference from red of the highest level (255). As a result, the monochromatic process of R is performed. Similarly, an element belonging to the G (green) color set is a G whose absolute value is 50 or less by obtaining a difference from the green of the highest level (255). Thereby, the monochromatic process of G is performed. The element belonging to the B (blue) color set is B whose absolute value of the difference is 50 or less by obtaining the difference from the green of the highest level (255). Thereby, the monochrome processing of B is performed.

  Based on the above color reduction rules, a set of R color, a set of G color, and a set of B color are determined. With these RGB, a full-color color photographic image 30 is a two-dimensional array of RGBX as shown in FIG. Is converted to Further, this RGBX two-dimensional array is reconstructed into an RGBX one-dimensional array as shown in FIG. 8 (step S13). In the RGBX one-dimensional array shown in FIG. 8, the other one color is replaced with a spacer (/).

  Further, the RGBX one-dimensional array is subjected to partitioning processing as shown in FIG. 9 (step S14). In this partitioning process, for the RGBX one-dimensional array shown in FIG. In other words, the partitioning process means that the RGBX two-dimensional array obtained by performing the color reduction process (step S12) on the color photographic image 30 is divided into eight sections. Therefore, when the sections 1 to 8 obtained by the partitioning process are shown in the image area 31 described above, it is as shown in FIG. According to the partitioning by the partitions 1 to 8 in this embodiment, the RGBX distribution state in the image region 31 is set to be relatively uniform in terms of the number. Since priority is given to equalizing the distribution in terms of the number of RGBX distributions, the areas of the sections 1 to 8 in the image region 31 are different and vary.

  Subsequent to step S14 for the partitioning process, for example, the segment 3 cut-out process is performed (step S15). Here, in the RGBX one-dimensional array obtained in step S13, the section 3 is selected from the sections 1 to 8 obtained in the partitioning step S14, and the RGBX one-dimensional array included in the section 3 is cut out. At this time, a process (suppress) for removing X which is the other one color is executed. As a result, the RGB one-dimensional array is cut out in step S15 where the cutting process is performed. FIG. 11 shows an RGB one-dimensional array relating to the cut out section 3.

  The section processing is performed in step S14 of partitioning, and one section 3 is cut out. However, two or more sections may be cut out, or all the sections (the entire color photographic image 30) may be used. .

  The cut out RGB one-dimensional array is stored in the memory according to the array order (step S16).

  In the next step S17, an address colorization process is executed. In the address colorization processing step S17, address colorization is performed on the RGB one-dimensional array of the section 3 extracted in the partitioning process (step S14). In this example, “address colorization” means that a serial number (address) is assigned to each element separately for each of the R set, G set, and B set for the RGB one-dimensional array in section 3. Means. That is, as shown in FIG. 11, by assigning an address to each element of the RGB one-dimensional array of the section 3 thus cut out, an “address color” is formed as shown in FIG. In the address numbering, numbering (numbering or numbering) is performed using the position number or the like for the same color.

  In the case of the address color of the RGB one-dimensional array in section 3 shown in FIG. 12, the R set is numbered from R1 to R13 for 13 “R” elements, and the 13 sets of “G” ”Elements are numbered from G1 to G13, and for the B set, 21“ B ”sets are numbered from B1 to B21. These R1 to R13, G1 to G13, and B1 to B21 are arranged in the arrangement order of the RGB one-dimensional array of the section 3. As for the RGB one-dimensional array related to the section 3 subjected to the address colorization processing, the address color one-dimensional array is generated in the memory in which they are stored (step S18). The “address color list” is created by assigning color numerical values using the generated one-dimensional array of address colors. However, at the time of step S18, the corresponding color numerical value is not assigned to each address color (Cn) of the address color one-dimensional array.

  FIG. 13 shows an example of the address color one-dimensional array generated as described above. No corresponding color value is assigned to each address color (Cn) of the address color one-dimensional array. Next, the address color is encoded using the address color one-dimensional array thus generated (step S20).

  Specific contents of the address color coding (step S20) are shown in FIG. 7B.

  This address color coding means that an object is assigned to each of the 47 address colors based on the one-dimensional array of address colors shown in FIG. 13 (step S21 in FIG. 7B), and an ONC correspondence table is created. doing. FIG. 14 shows an example of an O-Cn correspondence table that is a part of the created ONC correspondence table. In the case of this embodiment, the long sentence (computer object) 28 described with reference to FIG. 4 is divided and individual objects are determined. The number of divisions and the manner of division of the sentence 28 are arbitrary, but in this embodiment, the sentence 28 is divided so that an object is assigned to each of the 47 address colors (R1 to R13, G1 to G13, B1 to B21). . The correspondence relationship between each address color (Cn) and the object (O) is as shown in the list or chart shown in FIG. 14, and thereby an OC correspondence table is created. The address color coding in FIG. 14 shows an example of allocation from “Tani Denki Kogyo” in the address color B1 to “Small and light” in the address color R13.

  FIG. 15 shows the address color code table generated in step S22 (FIG. 7B). FIG. 15 is a table in which the object numbers (O) in the table of FIG. 14 are sorted by characters, words, phrases, and assigned a sequential color numerical value (N). According to the address color code table, the correspondence between the color numerical value (N), the object (O), and the address color (Cn) is shown. In the address color (Cn) column, a plurality of address colors (Cn) are associated with the same object (for example, “,”, “no”, etc.). The association between the color numerical value (N) and the object (O) / address color (Cn) can be arbitrarily determined.

  FIG. 16 shows an N-O correspondence part extracted from the correspondence table shown in FIG. 15 and shows it as an object list (encoding). The object list of FIG. 16 is created by step S23 (FIG. 7B) of object list generation.

  FIG. 17 shows an address color list indicating the correspondence between the address color (Cn) and the color numerical value (N). FIG. 16 is a table in which Cn-N correspondence portions are extracted from the correspondence table shown in FIG. 15 and sorted by alphanumeric characters of address colors (Cn). The address color list is created by the address color list generation step S24 (FIG. 7B). The address color list (encoding) shown in FIG. 17 corresponds to the address color list 21B described above. The ONC correspondence table 21 (object list 21A and address color list 21B) is created as described above.

  As described above, a color photographic image 30 is selected, RGB three-color color reduction is performed using the color photographic image 30, partitioning is performed, an RGB one-dimensional array of a predetermined section is cut out, and the RGB one-dimensional array is used. Each process of performing address color coding is performed on the information distribution apparatus 15 side.

  In the flowchart shown in FIG. 7B, in the preceding stage of the address color encoding process (S20), step S1 of "Preparation of text", step S11 of "Preparation of color photographic image (original drawing)", and "Address color" described above. A “one-dimensional array generation” process (S10) is provided.

  Next, with reference to FIGS. 18 to 22, a decoding process performed on the information receiving device 15 side will be described. The decoding process performed by the information receiving device 15 is an inverse conversion process that reverses the procedure of the encoding process described above.

  The decoding process performed on the information receiving device 15 side is the decoding of the address color (Cn). As described above, the ONC correspondence table 21 (object list 21A and address color list 21B) is provided to the information receiving device 15 side by mail or the like in advance from the information distribution device 14 side. Next, the color photographic image 21 </ b> C is transmitted from the information distribution device 14 to the information reception device 15 via the Internet 11. After receiving the color photographic image 21C, the information receiving device 15 performs reverse conversion as shown in FIG. 3A on the basis of the ONC correspondence table 21 (object list 21A and address color list 21B), and text as message information The object 24 is taken out. At this time, decoding (inverse transformation) is performed using the address color (Cn) determined as described above.

  FIG. 18 is a table for explaining decoding by address color. In this table, the address color (Cn) is shown in the first column, the color numerical value (N) is shown in the second column, the object (O) is shown in the third column, and the correspondence between each item It is shown.

  The information receiving apparatus 15 executes the decoding process according to the address color decoding flow shown in FIG.

  In the first step S31, a digital color photographic image (original drawing) is prepared. The color photographic image is sent from the information distribution apparatus 14 via the Internet 11. Here, the color photographic image includes color photographic print printing, and color printed material posted / pasted on storefront advertisements, books, display materials, and the like, which have been input by camera imaging / OCR imaging. Therefore, instead of a color photographic image, a color photographic print or a color print may be delivered from the information distribution side to the information reception side. Next, an address color one-dimensional array is taken out using the color photographic image (step S32). The taken-out address color one-dimensional array is shown in FIG. Next, the address color list shown in FIG. 19 is prepared (step S33). Further, an object list shown in FIG. 20 is prepared (step S34). The address color list and the object list are provided from the information distribution apparatus 14 side by mail or the like in advance. Finally, address color decoding is performed using the address color one-dimensional array, the address color list, and the object list (step S35). In this way, a predetermined address color (Cn) is extracted from the received color photographic image 21C based on the one-dimensional array of address colors, and based on the extracted address color (Cn), the address color list 21B shown in FIG. 19 is used. Get the color value (N). Next, based on the acquired color numerical value, the object list (decoding) 21A shown in FIG. 20 is used to construct a decoding table with the address colors shown in FIG.

The relationship between the pre-conversion matter (input) and the post-conversion matter (output) in each conversion process of “address color coding” and “address color decoding” described above is shown in FIGS. It becomes like this. In the conversion processing 51 based on the address color coding (tally division) shown in FIG. 23, the input is a color photo image (original drawing) of tally 1 and text (text object), and the output is an ONC correspondence table (object) of tally 2 List and address color list). Also, in the conversion process 52 based on the address color decoding (tally code) shown in FIG. 24, the input is a color photographic image (original drawing) of tally 1, and the output is text (text object). In the conversion process 52 based on the address color decoding, the ONC correspondence table (object list and address color list) of tally 2 is referred to.
Here, the ONC correspondence table can be decomposed into a combination of (object list and address color list). Conversely, according to the combination of (object list and address color list), an ONC correspondence table can be constructed. The combination of the ONC correspondence table and (object list and address color list) is equivalent.

  From the viewpoint of tally encryption technology, the encoding process is a process of encoding (encrypting) a text object by dividing it into a color photographic image (tally 1) and an ONC correspondence table (tally 2). . The decoding process is a process in which the color photographic image (tally 1) and the ONC correspondence table (tally 2) are tally-coded and decoded into a text object. Therefore, the address color technique is also an implementation form of a secret sharing technique for tally division using a color photographic image.

(Conversion processing) Conversion expression expression Encoding: Color photographic image (tally 1) + text object → ONC correspondence table (tally 2)
Decoding: Color photographic image (tally 1) + ONC correspondence table (tally 2) → text object where ONC correspondence table = {object list + address color list}

Furthermore, tally division is possible up to three divisions as follows.
Tally 1 = color photo image, tally 2 = ON table, tally 3 = CN table

FIG. 28 shows a configuration of a combination of selection of the Internet transmission route 61 and the recording medium conveyance route 62 when a color photographic image (tally 1) and an ONC correspondence table (tally 2) are transmitted or conveyed. Here, the category of recording media includes not only electronic recording media (USB memory, CD, FD, etc.) but also printing recording media (paper base).
Case (1) in FIG. 28 is the embodiment described above, and the tally-divided color photographic image (tally 1) is transmitted over the Internet, and the recording medium of the ONC correspondence table (tally 2) is delivered by mail or home delivery. So security is at a high level. However, if the security level is not strictly questioned, any one of cases (2) to (4) may be selected. Further, the application is expanded to color print media, and as in cases (5) and (6), after the color photographic image print print is conveyed as a print recording medium, the captured image captured by the camera is taken into the PC. Realization of a simple application is also possible. An example of this apparatus configuration is as described above with reference to FIG.

  The above address color system, encoding method, and decoding method are applied not only to information distribution but also to a single computer (PC, etc.), and texts (files) stored in the computer are used. It can also be used as an encryption system. FIG. 27 shows a configuration example for storing files such as text. Reference numeral 71 denotes one computer system. In the computer system 71, a PC (HD: hard disk) and a recording medium are shown as components. FIG. 27 shows the file storage location / means in a table format divided into cases (1) and (2).
