Description

  The present invention relates to an imprint image processing program, an imprint image processing method, and an information processing apparatus.

  In the procedures of public institutions and financial institutions, the identity of the procedural person may be required. The identity of the procedural person may be confirmed by presenting an identification card or authenticating a seal stamp.

  For example, the financial institution verifies the identity by comparing the seal of the registered seal registered in advance with the seal of the seal (checked seal) stamped by the procedure person at the time of the procedure. If the seal of the registered seal and the stamp of the collated seal are different, the financial institution does not carry out the procedure because the identity cannot be verified. To perform such imprint verification, a person in charge of a financial institution displays a seal image of a registered seal on the screen of the terminal device and compares it with the seal imprinted on the document by the procedure operator. There is.

As a technique using an imprint image, there is known a tally processing method in which it is difficult to forge a tally image.
When the person in charge at the financial institution goes to the customer and performs the procedure, the person in charge displays the imprint image of the registration stamp on the terminal brought by the person in charge, and the person in charge visually recognizes the imprint that the customer stamped on the document, There are cases where the imprint image is compared with the stamped imprint.

Hereinafter, embodiments will be described in detail with reference to the drawings.
[First Embodiment]
First, the information processing apparatus according to the first embodiment will be described with reference to FIG. FIG. 1 is a diagram illustrating an example of an information processing apparatus according to the first embodiment.

The information processing apparatus 1 is an apparatus that processes a seal image. The information processing apparatus 1 includes a control unit 2. The process executed by the control unit 2 can be provided as a program for processing an imprint image.
The control unit 2 acquires a first image 3 that is an imprint image. For example, the control unit 2 acquires, as the first image 3, data of a seal image of a registration mark registered in advance in a database of a public institution or a financial institution.

  The control unit 2 generates a second image that leaves only the image in the divided area for each divided area obtained by dividing the first image 3. In other words, the control unit 2 is an image in which, for each divided region obtained by dividing the first image 3, a portion other than the divided region is filled based on the background color in the first image 3 to have the same size as the first image 3. A second image A4a and a second image B4b are generated. For example, the control unit 2 generates, for each of the divided areas obtained by dividing the first image 3 in the vertical direction, the second image A4a and the second image B4b having a portion other than the divided area as the background color. The background color is a color other than the seal color in the seal image. For example, when the first image 3 is an image of two colors, black and white, and the imprint color is black, the background is white.

  The control unit 2 generates a third image 5 that is an image of the impression color of the first image 3. In other words, the control unit 2 generates the third image 5 that is an image obtained by painting the first image 3 on the basis of the color of the impression in the first image 3. For example, when the imprint color is black, the control unit 2 generates an image in which the same size (the same image size) as the first image 3 is painted in black as the third image 5.

  The control unit 2 generates a fourth image including the second image A4a, the second image B4b, and the third image 5 that specify the display order. For example, the control unit 2 sets the second image A4a as the fourth image A6a with the display order “1”. In addition, the control unit 2 sets the third image 5 as the fourth image B6b in the display order “2”. Further, the control unit 2 sets the second image B4b as the fourth image C6c with the display order “3”. In addition, the control unit 2 sets the third image 5 as the fourth image D6d having the display order “4”.

  The information processing apparatus 1 continuously displays the fourth image A6a, the fourth image B6b, the fourth image C6c, and the fourth image D6d according to the display order, so that a human impression is displayed as a single imprinted image. Visual observation is possible. However, when the image is taken by a photographing device such as a camera, any one of the fourth image A6a, the fourth image B6b, the fourth image C6c, and the fourth image D6d is taken. For this reason, it is difficult for the photographing device to photograph the entire seal image for the images in which the fourth image is continuously displayed.

  Further, the information processing apparatus 1 sets the display order in which at least two third images are displayed in a cycle in which the second images are continuously displayed and displayed as one seal impression. As a result, even if the imaging device displays the imprint image displayed by the information processing apparatus 1 by changing the shooting speed, only the second image cannot be continuously shot and the third image is shot. It will be. For this reason, it is difficult for the photographing device to photograph the entire seal image for the images in which the fourth image is continuously displayed.

  In this way, when displaying the seal image, the information processing apparatus 1 can prevent forgery of the seal by voyeuring the displayed seal image. Further, the information processing apparatus 1 can improve security in displaying a seal image.

[Second Embodiment]
Next, as a second embodiment, a seal image processing system in which the information processing apparatus 1 is applied to a server will be described with reference to FIG. FIG. 2 is a diagram illustrating an example of a seal image processing system according to the second embodiment.

A seal image processing system 400 in a financial institution or public institution is a system that provides a seal image of a registered seal (registered seal) in response to a request.
The imprint image processing system 400 includes a plurality of clients 100 and 110, and the clients 100 and 110 exchange information with the server 300 via the network 200.

  The server 300 is an information processing apparatus such as a computer that manages the database 350 and transmits / receives information used for processing a seal image with the clients 100 and 110. In addition, the server 300 can perform authentication processing of a password transmitted from a client and image processing of a seal image stored in the database 350.

  The database 350 is a database that holds a seal impression image of a registration mark. Prior to a request for an imprint image from a client, the database 350 holds an imprint image in advance. The database 350 stores a branch number, an account number, and the like in association with the seal image. Note that the branch number, the account number, and the like correspond to identification information for specifying the seal image.

The network 200 includes various networks such as a wired network and a wireless network that transmit and receive information between the clients 100 and 110 and the server 300.
The clients 100 and 110 are information processing apparatuses such as computers that transmit and receive information to and from the server 300. The client 100 is an example of a computer, and the client 110 is an example of a mobile terminal or a tablet terminal. These are merely examples of the client, and other devices may be used as the client.

  Here, a process in which a person in charge such as a financial institution displays a seal image using a client will be described. The person in charge inputs a login ID (Identifier) and a password at the client and logs in to the server 300 via the network 200. After login authentication in the server 300, the person in charge inputs identification information such as a branch number or an account number using the client, and transmits it to the server 300. The person in charge receives a seal image corresponding to the identification information from the server 300 using the client. The person in charge displays the received imprint image on the client and visually checks the imprint.

Next, the hardware configuration of the server according to the second embodiment will be described with reference to FIG. FIG. 3 is a diagram illustrating an example of a hardware configuration of the server according to the second embodiment.
Server 300 includes a control unit 310. The control unit 310 includes a processor 311, a RAM (Random Access Memory) 312, an HDD (Hard Disk Drive) 313, an input / output signal interface 314, a storage medium interface 315, and a communication interface 316. The server 300 is entirely controlled by a processor 311. A RAM 312 and a plurality of peripheral devices are connected to the processor 311 via a bus 317. The processor 311 may be a multiprocessor. The processor 311 is, for example, a central processing unit (CPU), a micro processing unit (MPU), a digital signal processor (DSP), an application specific integrated circuit (ASIC), or a programmable logic device (PLD). The processor 311 may be a combination of two or more elements among the CPU, MPU, DSP, ASIC, and PLD.

  The RAM 312 is used as a main storage device of the server 300. The RAM 312 temporarily stores at least part of an OS (Operating System) program and application programs to be executed by the processor 311. The RAM 312 stores various data necessary for processing by the processor 311.

Peripheral devices connected to the bus 317 include an HDD 313, an input / output signal interface 314, a storage medium interface 315, and a communication interface 316.
The HDD 313 magnetically writes and reads data to and from the built-in disk. The HDD 313 is used as an auxiliary storage device of the server 300. The HDD 313 stores an OS program, application programs, and various data. In addition, not only HDD313 but SSD (Solid State Drive) can also be used. Note that a semiconductor storage device such as a flash memory can also be used as the auxiliary storage device.

  An input / output device 318 is connected to the input / output signal interface 314. The input / output device 318 includes an input device and an output device. Examples of input devices include a keyboard, a mouse, and a touch panel. Examples of the output device include a monitor, a liquid crystal display, and various panel display devices.

  The input / output signal interface 314 transmits a signal sent from the keyboard or mouse to the processor 311. Note that the mouse is an example of a pointing device, and other pointing devices can be used. Examples of other pointing devices include a touch panel, a tablet, a touch pad, and a trackball.

  The output device of the input / output device 318 displays an image on the monitor screen in accordance with an instruction from the processor 311. Examples of the monitor include a display device using a CRT (Cathode Ray Tube) and a liquid crystal display device.

  The storage medium interface 315 reads and writes data recorded on the storage medium 319 using magnetism, laser, or the like. Further, the storage medium interface 315 may read data recorded in a storage medium such as a semiconductor memory. The storage medium 319 includes, for example, an optical disk, a semiconductor memory such as a flash memory, and the like. An optical disc is a portable recording medium on which data is recorded so that it can be read by reflection of light. Optical discs include DVD (Digital Versatile Disc), DVD-RAM, CD-ROM (Compact Disc? Read Only Memory), CD-R (Recordable) / RW (ReWritable), and the like.

  The storage medium interface 315 can also be used as a communication interface for connecting peripheral devices to the server 300. For example, a memory device or a memory reader / writer can be connected to the storage medium interface 315. The memory device is a recording medium equipped with a communication function with the storage medium interface 315. A memory reader / writer is a device that writes data to a memory card or reads data from a memory card. A memory card is a card-type recording medium.

  The communication interface 316 is connected to the database 350 and the network 200. The communication interface 316 transmits / receives data to / from other computers, storage devices, or communication devices.

  With the hardware configuration as described above, the processing functions of the server 300 of the second embodiment can be realized. The information processing apparatus 1 according to the first embodiment can also be realized by the hardware configuration of the server 300 illustrated in FIG. Note that the client of the second embodiment can also be realized by the hardware configuration of the server 300 shown in FIG.

  The server 300 implements the processing functions of the second embodiment by executing a program recorded on a computer-readable recording medium, for example. A program describing the processing contents to be executed by the server 300 can be recorded in various recording media. For example, a program to be executed by the server 300 can be stored in the HDD 313. The processor 311 loads at least a part of the program in the HDD 313 into the RAM 312 and executes the program. The program executed by the server 300 can be recorded on a portable recording medium such as an optical disc, a memory device, or a memory card. The program stored in the portable recording medium becomes executable after being installed in the HDD 313 under the control of the processor 311, for example. The processor 311 can also read and execute the program directly from the portable recording medium.

Next, the seal image registration information will be described with reference to FIG. FIG. 4 is a diagram illustrating an example of seal image registration information according to the second embodiment.
The imprint image registration information 500 is information relating to a registration stamp registered in advance, and is stored in the database 350.

  The seal image registration information 500 includes a store number, a subject code, an account number, and a seal image of a registration stamp. The store number is a code for identifying a head office or a branch such as a financial institution. The course code is a code for identifying an account type such as an ordinary account, a current account, and a savings account. The account number is a code for identifying the account. The imprint image is image data of an imprint image of a registration stamp corresponding to an account. The imprint image registration information may include the name of the account owner or the name of the corporation. The store number, subject code, and account number are only examples of identification information, and other items may be used as identification information.

Next, server processing according to the second embodiment will be described with reference to FIG. FIG. 5 is a diagram illustrating a flowchart of server processing according to the second embodiment.
The server process shows the overall flow of the process executed by the server 300. The processor 311 of the control unit 310 executes server processing after authenticating and permitting login from the client.

  [Step S11] The processor 311 receives a seal image request from the client. The imprint image request is information for requesting an imprint image, and includes identification information for specifying the imprint image. For example, the processor 311 receives a store number, a subject code, and an account number as identification information.

[Step S12] The processor 311 acquires from the database 350 the imprint image specified by the imprint image request.
[Step S13] The processor 311 executes a seal image division process. The imprint image division process is a process of dividing the acquired imprint image and generating a divided image. The imprint image division process will be described later with reference to FIG.

  [Step S14] The processor 311 executes a solid image insertion process. The filled image insertion process is a process of inserting a filled image between the divided images generated by the seal image dividing process. The filled image insertion process will be described later with reference to FIG.

  [Step S15] The processor 311 executes image transmission processing. The image transmission process is a process of transmitting the divided image and the painted image to the client. The image transmission process will be described later with reference to FIG.

  Next, the imprint image division processing according to the second embodiment will be described with reference to FIGS. FIG. 6 is a diagram illustrating a flowchart of the imprint image dividing process according to the second embodiment. FIG. 7 is a diagram illustrating an example of a setting image of divided areas according to the second embodiment. FIG. 8 is a diagram illustrating an example of a divided image according to the second embodiment. FIG. 9 is a diagram illustrating an example of the display order of the divided images according to the second embodiment.

  The imprint image division process is a process of dividing the acquired imprint image and generating a divided image. The imprint image division process is a process executed by the processor 311 of the control unit 310 in step S13 of the server process.

  [Step S21] The processor 311 determines the horizontal image division size of the acquired imprint image. Here, the horizontal image division size will be described using a division region setting image 600 (shown in FIG. 7). The horizontal image division size 602 (shown in FIG. 7) is a value obtained by dividing the horizontal image size 601 (shown in FIG. 7), which is the horizontal length of the imprint image, by the horizontal division number. The number of horizontal divisions may be a predetermined number (for example, “4” in FIG. 7) or a value set by an administrator. Further, the horizontal division number may be a value set in accordance with the shape, character size, etc. of the seal impression display portion 606 (shown in FIG. 7). The imprint display portion 606 is a portion that displays an imprint in the imprint image (for example, a circular frame surrounding the stamp “Sawada” in FIG. 7 and a portion inside the circular frame).

  [Step S22] The processor 311 determines the vertical image division size of the acquired seal image. The vertical image division size 604 (shown in FIG. 7) is a value obtained by dividing the imprint image by the vertical image size 603 (shown in FIG. 7), which is the length in the vertical direction, by the number of vertical divisions. In FIG. 7, the horizontal division number and the vertical division number are both “4”, but may be different values. The number of vertical divisions may be a predetermined number or a value set by an administrator. The number of vertical divisions may be a value set according to the shape of the seal impression display portion 606, the character size, or the like.

  Here, a case where the processor 311 sets the number of horizontal divisions and the number of vertical divisions according to the shape, character size, and the like of the seal impression display portion 606 will be described. For example, the processor 311 sets the number of horizontal divisions and the number of vertical divisions so that the imprint display portion 606 of the imprint image is divided into a plurality of divisions (9 divisions in FIG. 7). The size, shape, and the like of the imprint display portion 606 in the imprint image vary depending on the size, shape, and the like of the stamped seal. For this reason, the imprint image includes an imprint image having many blank portions other than the imprint display portion 606. When the number of horizontal divisions and the number of vertical divisions are set only by the size of the imprint image and the outer peripheral shape, the processor 311 may not be able to generate a divided image that contributes to improving security. For example, if the imprint display portion 606 is large enough to fit in the upper half area, the processor 311 cannot divide the imprint display portion 606 even if the imprint image is divided into two parts in the upper and lower directions to generate a divided image. Therefore, the processor 311 sets the number of horizontal divisions and the number of vertical divisions according to the shape, character size, etc. of the imprint display portion 606 so as to divide the imprint display portion 606 into a plurality of pieces.

  [Step S23] The processor 311 sets an initial value (division initial position) of the division position of the seal image. The division initial position 605 (shown in FIG. 7) is an initial position for dividing the seal image. The division initial position 605 is the position of the upper left corner of the imprint image in the example shown in FIG. 7, but may be other positions.

  [Step S24] The processor 311 divides the seal image based on the division position. The processor 311 divides the impression image as a rectangular area with the horizontal position as the horizontal image division size 602 and the vertical length as the vertical image division size 604, starting from the division position. Each region obtained by dividing the imprint image is represented by 16 divided regions (shown in FIG. 7) divided into a matrix of 4 rows and 4 columns. Each divided area can be identified by a row and a column. For example, the upper left divided area is identified as a divided area a1, and the lower right divided area is identified as a divided area d4. In the example of FIG. 7, the number of divisions of the seal image is “4” in both the horizontal direction and the vertical direction. It should be noted that the lower limit number of divisions of the imprint image is either the horizontal direction “2” and the vertical direction “1”, or the horizontal direction “1” and the vertical direction “2”.

  [Step S25] The processor 311 determines whether or not the divided area divided in step S24 includes an imprint color (the display color of the imprint in the imprint image). For example, the processor 311 determines that the divided areas a1, a2, a3, b1, b2, b3, c1, c2, and c3 (shown in FIG. 7) are areas that include the imprint color. Further, the processor 311 determines that the divided areas a4, b4, c4, d1, d2, d3, and d4 (shown in FIG. 7) do not include the imprint color. The processor 311 proceeds to step S26 when the divided area includes the imprint color, and proceeds to step S28 when the divided area does not include the imprint color.

  [Step S26] The processor 311 generates a divided image based on the divided region divided in step S24. The processor 311 generates an image in which a portion other than the divided region is filled with the background color (background color) of the imprint image.

  Here, the divided image 610 (shown in FIG. 8) generated by the processor 311 will be described. For example, when the divided area a1 is divided in step S24, the processor 311 paints a portion other than the divided area a1 of the imprint image with the background color, and generates a divided image a1p611 (shown in FIG. 8). The background color is a color of a portion other than the seal color in the seal image. For example, in the imprint image, when the imprint color is black and the color of the portion other than the imprint color is white, the background color of the divided image a1p611 is white. Similarly, when the divided area a2 is divided in step S24, the processor 311 generates a divided image a2p612 (shown in FIG. 8) by painting a portion other than the divided area a2 with the background color. Similarly, the processor 311 generates a divided image a3p613, a divided image b1p614, a divided image b2p615, a divided image b3p616, a divided image c1p617, a divided image c2p618, and a divided image c3p619 (shown in FIG. 8).

  In addition, the color which paints parts other than a division area is not restricted to the same color as a background color, A similar color etc. may be sufficient. For example, when the background color is light yellow, the processor 311 may determine that the color for painting a portion other than the divided region is white.

  Note that the processor 311 sets only a divided region including the imprint color (in other words, a divided region including the imprint display portion 606) as a target for generating a divided image. The reason for this is that if there is a background image that does not include the imprint color but only a background color, depending on the display order, there will be no filled image between the split images that include the seal color. This is because there is a risk of trouble. Further, the processor 311 does not need to generate a divided image of only the background color, and can suppress the number of divided images. Thereby, the processor 311 can suppress the data amount of the image transmitted to the client.

  [Step S27] The processor 311 assigns a display order to the generated divided images. The processor 311 sets the initial value of the display order to “1”, and thereafter assigns the display order to the divided images as “2, 3, 4,...” In ascending order. For example, the processor 311 assigns the display order “1” to the divided image a1p including the first generated divided region a1 (shown in FIG. 9). Similarly, the display order “9” is assigned to the divided image c3p (shown in FIG. 9).

  [Step S28] The processor 311 determines the division position of the seal image. The processor 311 determines a position obtained by moving the horizontal image division size 602 from the division position to the right horizontal direction as a new division position. Note that when the division position is located in the left horizontal direction from the right edge of the imprint image to the horizontal image division size 602 (in other words, when the image has been divided to the right edge), the processor 311 vertically divides the imprint image to the left edge and below. The position moved by the size 604 is determined as a new division position.

  [Step S29] The processor 311 determines whether or not the division of the seal image has been completed. For example, the processor 311 can determine that the division of the imprint image has been completed when the division position determined in step S28 is located below the left end of the imprint image.

The processor 311 proceeds to step S24 when determining that the division of the imprint image is not completed, and ends the process when determining that the division of the imprint image is completed.
Next, the filled image insertion process of the second embodiment will be described with reference to FIGS. FIG. 10 is a diagram illustrating a flowchart of a filled image insertion process according to the second embodiment. FIG. 11 is a diagram illustrating an example of the display order of divided images and filled images according to the second embodiment.

  The filled image insertion process is a process of inserting a filled image between the divided images generated by the seal image dividing process. The filled image insertion process is a process executed by the processor 311 of the control unit 310 in step S14 of the server process.

  [Step S31] The processor 311 determines the color of the filled image and the area of the filled image. The processor 311 fills the same color as the imprint color of the imprint image acquired in step S12 as a color of the image, and determines a rectangular area of horizontal length horizontal image size 601 and vertical length vertical image size 603. Are filled and determined as an image area. For example, if the seal color is black in the seal image, the processor 311 can determine that the color of the filled image is black. Further, the processor 311 can determine a rectangular area having the same size as that of the seal impression image as an area of the image.

  Note that the color of the painted image is not limited to the same color as the seal impression color, and may be a similar color or the like. For example, when the seal color is vermilion, the processor 311 may determine that the color of the filled image is red.

  [Step S32] The processor 311 determines the number of filled images. The number of filled images may be a predetermined value (for example, “2”) or may be calculated according to the number of divisions of the imprint image. It should be noted that the minimum number of painted images is 2 in total, one painted image displayed in the middle of the divided image and one painted image displayed at the end of the divided image.

  When the number of painted images is calculated according to the number of divisions of the imprint image, for example, it can be calculated as a value obtained by adding the number of painted images inserted in the middle to one painted image to be displayed last. The number of painted images to be inserted in the middle can be calculated as a quotient value obtained by dividing the total number of image divisions by the lower limit number of division numbers and rounding up after the decimal point.

  [Step S33] The processor 311 determines the display period of the filled image. The display cycle is a value that determines how many divided images are displayed and then a filled image is displayed. The display cycle can be calculated as a quotient value obtained by dividing the number of divided images by the number of filled images and dividing the number of decimals. For example, the result of dividing the divided image number “9” by the painted image number “2” is “4.5”. The display period is rounded up to “4.5” to become “5”. In this case, the processor 311 displays five divided images based on the display cycle “5”, and then displays a filled image.

  [Step S34] The processor 311 determines the display order of the filled image and the divided image by inserting the filled image into the display order of the divided images based on the display cycle obtained in step S33. For example, in the case of the display cycle “5”, the processor 311 sets the order of displaying the first painted image F1p after displaying the five divided images a1p, a2p, a3p, b1p, and b2p. The processor 311 inserts the filled image F1p into the display order “6” (shown in FIG. 11). Accordingly, the subsequent images are moved down from the display order shown in FIG. 9, the divided image b3p is the display order “7”, the divided image c1p is the display order “8”, the divided image c2p is the display order “9”, The image c3p becomes the display order “10” (shown in FIG. 11). The processor 311 inserts the second filled image F2p last. For this reason, the filled image F2p has the display order “11” (shown in FIG. 11).

  Next, image transmission processing according to the second embodiment will be described with reference to FIGS. FIG. 12 is a diagram illustrating a flowchart of image transmission processing according to the second embodiment. FIG. 13 is a diagram illustrating an example of an image file according to the second embodiment.

  The image transmission process is a process of transmitting the divided image and the painted image to the client. The image transmission process is a process executed by the processor 311 of the control unit 310 in step S15 of the server process.

  [Step S41] The processor 311 generates an image file including a filled image and a divided image based on the display order. For example, the image file 700 (shown in FIG. 13) includes a divided image a1p701, a divided image a2p702, a divided image a3p703, a divided image b1p704, and a divided image b2p705. The image file 700 includes a filled image F1p706, a divided image b3p707, a divided image c1p708, a divided image c2p709, a divided image c3p710, and a filled image F2p711.

  The image file may be any file as long as the divided image and the painted image can be continuously displayed in the display order. For example, the processor 311 can generate an animation GIF (Graphics Interchange Format) including divided images and filled images as an image file. Further, the processor 311 may generate an image file conforming to the MPEG (Moving Picture Experts Group) standard including the divided image and the filled image, or may generate an image file conforming to another standard. . Further, the processor 311 may generate a single file obtained by combining a plurality of divided images and a filled image as an image file.

  Note that the processor 311 may set a display time for continuously displaying the filled image and the divided image according to the display order. For example, the processor 311 may set the display time so as to display all the painted images and the divided images included in the image file in a predetermined time (for example, 1 second). Further, the processor 311 may set the display time according to the display order so that a predetermined number of images (for example, 20 to 30 images) are displayed in one second.

[Step S42] The processor 311 transmits the image file 700 generated in step S41 to the client.
Next, image transmission processing according to the second embodiment will be described with reference to FIGS. FIG. 14 is a diagram illustrating a flowchart of client processing according to the second embodiment. FIG. 15 is a diagram illustrating an example of an image file displayed on the client according to the second embodiment.

  The client process is a process in which the client transmits an imprint image request to the server and the imprint image corresponding to the imprint image request is displayed on the client. The client process is a process executed by the processor 311 of the client control unit 310 after login authentication to the server is permitted.

[Step S51] The processor 311 transmits a seal image request to the server.
[Step S52] The processor 311 receives an image file corresponding to the seal image request from the server.

  [Step S53] The processor 311 displays the image file received in step S52. The processor 311 can perform display processing according to the image file. For example, when the received image file is an animation GIF, the processor 311 can start a browser software on the client and display a seal image. Further, when the received moving image file is an image file conforming to the MPEG standard, the processor 311 can start moving image reproduction software corresponding to the MPEG standard and display a seal image.

  When the received image file includes a plurality of divided images and filled images (shown in FIG. 15A), the processor 311 divides the divided images 801, the filled images 802, and the divided images according to the display order. A seal impression image can be displayed by continuously displaying 803 and the filled image 804.

  Further, when the received image file is one image file 805 in which a plurality of divided images and filled images are combined (shown in FIG. 15B), the processor 311 displays the display areas 8051, An imprint image can be displayed by continuously displaying 8052, 8053, and 8054.

Note that the processor 311 can display the image file according to the display time when the display time is set in the image file.
As described above, the client receives a divided image obtained by dividing the seal image and a painted image from the server 300. The client continuously displays the received divided images and filled images. When a human sees the screen on which the divided image and the painted image are continuously displayed, the image is viewed as an imprint image, and when the image is captured by an image capturing device such as a camera, a part of the imprint image or a painted image is captured. The For this reason, the server 300 can improve the security at the time of displaying an imprint image by providing the divided image obtained by dividing the imprint image and the painted image.

  Also, even if the imprint image is voyeurized by changing the shooting speed of the photographic device, the screen where the image is inserted into the divided image is voyeurized, so the voyeurized image becomes a painted image. It is difficult to capture the entire imprint image. In the embodiment, the imprint image is described as an example, but the present invention may be applied to other than the imprint image (for example, a sign image).

In this way, the server 300 can improve the security in displaying the seal impression image by providing the divided image obtained by dividing the seal impression image and the painted image.
Note that the processing of the server 300 and the client described above is merely an example, and the processing of the client may be executed by the server 300, or the processing of the server 300 may be executed by the client.

  The above processing functions can be realized by a computer. In that case, a program describing the processing contents of the functions that the information processing apparatus 1, the server 300, and the clients 100 and 110 should have is provided. By executing the program on a computer, the above processing functions are realized on the computer. The program describing the processing contents can be recorded on a computer-readable recording medium. Examples of the computer-readable recording medium include a magnetic storage device, an optical disk, a magneto-optical recording medium, and a semiconductor memory. The magnetic storage device includes a hard disk device (HDD), a flexible disk (FD), a magnetic tape, and the like. Optical discs include DVD, DVD-RAM, CD-ROM / RW, and the like. Magneto-optical recording media include MO (Magneto-Optical disk).

  When distributing the program, for example, portable recording media such as a DVD and a CD-ROM in which the program is recorded are sold. It is also possible to store the program in a storage device of a server computer and transfer the program from the server computer to another computer via a network.

  The computer that executes the program stores, for example, the program recorded on the portable recording medium or the program transferred from the server computer in its own storage device. The computer reads the program from its own storage device and executes processing according to the program. The computer can also read the program directly from the portable recording medium and execute processing according to the program. In addition, each time a program is transferred from a server computer connected via a network, the computer can sequentially execute processing according to the received program.

  In addition, at least a part of the processing functions described above can be realized by an electronic circuit such as a DSP, ASIC, or PLD.
