Description

  The present invention relates to an image information collection apparatus that collects attribute information about an image, a method thereof, and a program thereof.

  Conventionally, when various information services (downloading, account creation, etc.) are used on a network such as the Internet, a technique called image authentication is used. Image authentication is an authentication system that prevents unauthorized access (such as random and continuous password entry) from a malicious program. For example, an image with a modified background or character angle, Some display a recognizable image and input text representing the image.

On the other hand, in order to generate a search index on a search site or to extract keywords from sentences posted on a website on the Internet, it is effective to maintain a dictionary that collects keywords. In addition, by maintaining an image database in which an image and a keyword representing the image correspond, it is possible to determine what the image on the web content represents. For example, by storing an image of a celebrity or celebrity such as a talent and a person name representing the image in association with each other, it can be effectively used as a person image database.
As described above, as a technique for associating an image with a name, a technique for recognizing characters from input image data and extracting a person's name is known (see, for example, Patent Document 1).

JP 2000-148912 A

However, in Patent Document 1, since a person name is not always displayed in image data, it is not feasible to collect data in which an image and a person name are associated with each other. In addition, when a plurality of persons are displayed in the image data, it is difficult to specify the persons, and the feasibility is poor.
In addition, text is usually displayed along with images on a web page, and it may be possible to extract a character string that seems to be a person name from this text, but multiple people are displayed in the image. In this case, it is very difficult to associate the person in the image with the name in the text. In addition, the name of the person is not limited to the last name and the first name, and is expressed in various forms, so it is difficult to extract the name from the text.
Furthermore, since celebrities etc. appear one after another, there is a problem that it takes time to register in the database sequentially each time a new celebrity appears.

For example, an intranet such as a LAN (Local Area Network), a network such as a communication line network or a broadcasting network in which a plurality of base stations capable of transmitting and receiving information via a wireless medium constitute a network, and a medium for directly receiving data Any configuration that transmits and receives data, such as the wireless medium itself, can be used.

The authentication server 100 has a function of performing image authentication and collecting names of persons displayed on the image. That is, the authentication server 100 functions as an image information collection device having an image authentication function in the present invention.
As shown in FIG. 2, the authentication server 100 includes, as storage means, an authentication image database 101 used for image authentication, a person image database 102 as image storage means used for collecting person names, and input candidate storage means. As a text candidate database 103.

  For example, as shown in Table 1 below, the authentication image database 101 has a table structure in which authentication text, which is attribute information about the authentication image, is stored as one record for each authentication image data. In the present embodiment, the name of an object displayed on the authentication image is stored as text as attribute information related to the authentication image. The authentication image is not particularly limited as long as anyone can recognize it. The authentication image database 101 stores authentication image data and authentication text in advance.

  For example, as shown in Table 2 below, the person image database 102 has a table structure in which person name text, which is attribute information about the person image, is stored as one record for each person image data. In the person name text, the name of the person displayed in the person image is stored as text. In the person image database 102, person name texts for person image data are collected. Therefore, there are cases where person name texts for each person image data are stored and those for which no person name text is stored. Moreover, it is not restricted to these items, The acquisition date of person image data, etc. may be stored in association with person image data.

  In the text candidate database 103, for example, as shown in Table 3 below, for each person image data, a person name candidate that is a candidate for attribute information related to this person image and the number of times the same person name candidate has been input are displayed. The table structure is stored as one record. As the person image data, the person image data stored in the aforementioned person image database 102 is stored, and a plurality of person name candidates may exist for one person image data. As the person name candidate, the person name input by the user is stored as text, and as the number of inputs, the number of times the person name is input is stored.

The authentication server 100 also includes a text input request unit 110 as an arithmetic processing unit, an input text acquisition unit 120 as an input information acquisition unit, a registration determination unit 130, and a text storage unit 140 as an input information storage unit.

Moreover, although not shown in figure, you may provide the data transmission / reception means which transmits / receives data via the internet 20, the output means which outputs a web page as a screen display, input means, such as a keyboard, etc.
The text input request unit 110 functions as part of the attribute information input request unit and the image authentication unit of the present invention.

The text input request unit 110 transmits an authentication page for authenticating the use of the service to the terminal device 300. This authentication page represents an authentication image for performing image authentication, a text field in which the name of an object displayed on the authentication image can be input, a person image for collecting a person name, and the person image. A text field in which a person name can be entered is displayed. Authentication image data extracted at random from the authentication image database 101 is displayed as the authentication image, and person image data extracted from the person image database 102 is displayed as the person image. When extracting person image data, image data in which no data is stored in the person name text of the person image database 102 is extracted preferentially. It should be noted that person image data with an acquired date and time may be preferentially extracted.
A screen in which the authentication page displaying such information is displayed by the output unit of the terminal device 300 is specifically shown in FIG.

As shown in FIG. 3, the authentication page 30 includes an authentication area 31 for image authentication, a person area 32 for collecting person names, an OK button 33 and a cancel button 34.
In the authentication area 31, an authentication image 311, an authentication text input unit 312 capable of inputting a name representing the authentication image 311, and a question display unit in which a question sentence for prompting input of the name of the authentication image 311 is written in text 313 and image changing means 314 capable of changing the authentication image 311 to another image are provided. The authentication image 311 is randomly selected from the authentication image data stored in the authentication image database 101 and displayed. In the authentication text input unit 312, the name of what the authentication image displayed as the authentication image 311 represents is input. The question displayed on the question display unit 313 preferably has a content that allows the name of the authentication image 311 to be answered. For example, as shown in FIG. 3, an answer “cat” can be guided to the authentication text input unit 312 by displaying a text “What is reflected?” On the question display unit 313. The image changing unit 314 can change the authentication image data displayed on the authentication image 311. For example, by clicking the image changing unit 314, a change request is transmitted to the authentication server 100, and the authentication server 100 randomly acquires another image data from the authentication image database 101 and enters the authentication page 30 as the authentication image 311. Display.

  In the person area 32, a person image 321, a person name input unit 322 that can input the name of the person displayed in the person image 321, and a question sentence for prompting input of the person name of the person image 321 are text. A described question display unit 323 and an image changing unit 324 capable of changing the person image 321 to another image are provided. The person image 321 is selected from the person image data stored in the person image database 102 and displayed. The person name input unit 322 inputs the name of the person displayed as the person image 321. The question displayed on the question display unit 323 preferably has a content that allows the person name of the person image 321 to be answered. For example, as shown in FIG. 3, by displaying the text “Who is captured?” On the question display unit 323, the person name of the person displayed in the person image 321 is guided to the person name input unit 322. Can do. The image changing unit 324 can change the image data displayed in the person image 321. For example, by clicking the image changing unit 324, a change request is transmitted to the authentication server 100, and the authentication server 100 acquires another person image data from the person image database 102 and displays it on the authentication page 30 as a person image 321. Let

  The input text acquisition unit 120 acquires the authentication text input to the authentication text input unit 312 and the person name text input to the person name input unit 322 in the authentication page 30 displayed on the output unit of the terminal device 300. . Specifically, these texts input by the terminal device 300 are transmitted to the authentication server 100 and received by the data transmission / reception means of the authentication server 100.

  The registration determination unit 130 determines whether or not a person text among the acquired texts can be registered in the person image database 102. Specifically, the person image data displayed as the person image 321 of the authentication page 30 and the person text acquired by the input text acquisition unit 120 are used as the person image data and the text candidate stored in the text candidate database 103. Associate with. Registration is possible if the number of input times of the corresponding person image data and text candidate is 2 or more, and registration is not possible if the number of input times is less than 2. That is, in the present embodiment, registration is possible when the same person name text is input three times or more for one image. Therefore, if the number of times of input is 1, the number of times of input in the text candidate database 103 is updated to a value of plus 1, and if the corresponding text is not registered, it is newly stored in the text candidate database 103.

  The text storage unit 140 causes the person image database 102 to store the person name text determined to be registerable by the registration determination unit 130. Since the person image data has already been registered in the person image database 102, only the person name text is updated. One or more person name texts can be stored for one image data. If the same person name text has already been registered, registration is not performed.

  The authentication unit 150 determines whether or not authentication is possible using the authentication image and the authentication text among the acquired text. Specifically, the authentication image data displayed as the authentication image 311 of the authentication page 30 and the authentication text acquired by the input text acquisition unit 120 are used as the authentication image data and the authentication text stored in the authentication image database 101. Associate with. If there is corresponding authentication image data and authentication text, authentication is permitted. Since the authentication image database 101 stores a plurality of authentication texts for one image data, the authentication image database 101 only needs to match any one authentication text. If there is no matching authentication text, authentication is not possible.

  The service providing unit 160 provides a service when authentication by the authentication unit 150 is permitted. The services include various services such as download and creation of a new account. When authentication is successful, the top page and service start page of each service are transmitted to the terminal device 300 and displayed on these web pages. Various services can be used depending on the content.

The image acquisition unit 170 accesses the news server 200 via the Internet 20 and acquires an image on a web page provided by the news server 200. In order to acquire an image, an image crawler is specifically used. An image crawler is a program that comprehensively collects images of web pages on the Internet.
The face extraction unit 180 extracts a region including a human face from the image acquired by the image acquisition unit 170, and stores the image data including the extracted face region in the human image database 102 as human image data. The image data may be extracted to such an extent that one person's face can be recognized. In addition, in the case of an image in which a plurality of people are displayed, a face for each person is extracted.

  The news server 200 is a device that provides various types of information on a website, and a web page having an image on which a person is displayed is registered. These images are acquired by the image acquisition means 170 of the authentication server 100 described above.

Although not shown, the terminal device 300 requests the authentication server 100 for a service to be used as an arithmetic processing unit, receives a web page of the requested service, and outputs the web page as a screen display. Means and input means such as a mouse and a keyboard capable of inputting characters. On the other hand, the storage means includes a database for storing form data related to various forms. Although it does not specifically limit as the terminal device 300, For example, a mobile telephone, a notebook personal computer, etc. are mentioned.
1 illustrates a configuration in which one terminal device 300 and one authentication server 100 are connected, but the authentication server 100 is actually connected to many terminal devices 300.

[Operation of authentication system]
Next, operation | movement of the authentication system 10 is demonstrated based on FIG.1, FIG.2 and FIG.4.
First, in order to access the authentication server 100, the user performs an input operation on the input unit of the terminal device 300, for example, activates a web browser and inputs an address, and requests an information service to be used, for example, a download service.
In step S1, when the authentication server 100 receives a request for information service by a transmission / reception means (not shown), authentication page information such as authentication image data or person image data to be displayed as the authentication page 30 shown in FIG. 3 in step S2. Is transmitted to the terminal device 300. The authentication image data is displayed as the authentication image 311 and is extracted at random from the authentication image data stored in the authentication image database 101. The person image data is displayed as a person image 321. Among the person image data stored in the person image database 102, person image data with no person name text registered is preferentially extracted. Further, image data with an older acquisition date may be preferentially extracted.

  The terminal device 300 receives the authentication page information by a transmission / reception unit (not shown), and displays an image of the authentication page 30 by an output unit. As a result, on the authentication page 30, the user can input the text to the authentication text input unit 312 using the input means for the name of the object displayed on the authentication image 311, and the person displayed on the person image 321. Text can be input to the person name input unit 322 by using a person name input means. When the user presses the OK button 33, the authentication text information input to the authentication text input unit 312 and the person name text information input to the person name input unit 322 are transmitted to the authentication server 100.

In step S3, the input text acquisition means 120 of the authentication server 100 acquires the authentication text information and the person name text information input by the terminal device 300, and proceeds to step S4. Specifically, authentication text information and person name text information are received by the transmission / reception means.
In step S <b> 4, the registration determination unit 130 determines whether the person image data displayed as the person image 321 and the acquired person name text information can be registered in the person image database 102. Specifically, the person image data and person name text information displayed as the person image 321 are collated with the person image data and text candidates stored in the text candidate database 103. If there is a text candidate that matches the acquired person name text information, if the input number is two or more, it is determined that registration is possible, and the process proceeds to step S5. On the other hand, if the number of inputs is less than 2, it is determined that registration is not possible because there is no input greater than or equal to the predetermined number, and the process proceeds to step S6.

In step S5, the registered person name text information is stored as the person name text of the corresponding person image data stored in the person image database 102, and the process proceeds to step S7. In addition, registration is not performed when the person name text information acquired as the person name text of the corresponding person image data in the person image database 102 is already stored. Then, the corresponding person image data in the text candidate database 103 and the number of input text candidates are updated with a value obtained by adding one.
In step S6, the corresponding person image data in the text candidate database 103 is updated with a value obtained by adding 1 to the number of input text candidates. If there is no text candidate that matches the acquired person name text information in the text candidate database 103, the text candidate database 103 is newly stored and the process proceeds to step S7.

In step S <b> 7, the authentication unit 150 determines whether the authentication image data displayed as the authentication image 311 and the authentication text information input to the authentication text input unit 312 match the authentication image data and the authentication text registered in the authentication image database 101. If it matches, the authentication is permitted and the process proceeds to step S8. On the other hand, if the authentication texts do not match, authentication is not possible, and the process returns to step S2 to send the authentication page 30 again to request text input.
In step S <b> 8, the service providing unit 160 provides various services to the terminal device 300. In the present embodiment, as a download service, for example, a file to be downloaded is transmitted and displayed on the screen by the output means of the terminal device 300 or the like.

  The image acquisition unit 170 accesses the news server 200 from time to time using an image crawler, acquires an image on a web page, extracts a person's face from the image acquired by the face extraction unit 180, and uses the person image as human image data. It is stored in the database 102.

[Effects of First Embodiment]
In the first embodiment described above, the following operational effects can be achieved.
The authentication server 100 performs image authentication using the authentication image and the authentication text displayed on the authentication page 30 by the authentication unit 150, while the person displayed on the person image 321 of the authentication page 30 by the registration determination unit 130 and the text storage unit 140. Are stored in the person image database 102.
That is, each time authentication is performed, the names of persons displayed in the person image 321 can be collected, and statistical data can be collected without making the user aware of the collection of data. Can do. Further, when the same person name is input three times or more for one image, the person text is stored in the person image database 102, so that highly reliable data can be collected. The collected human image database 102 can be widely used for creating a search index and the like, and is highly useful.

Steps S31 to S33 operate in the same manner as Steps S1 to S3 in the first embodiment, and Steps S36 and S37 operate in the same manner as Steps S7 and S8 in the first embodiment. Step S35 will be described.
In step S <b> 34, the registration determination unit 131 determines whether the person name text information input to the person name input unit 322 can be registered in the person image database 102 for the person image data displayed as the person image 321. To do. Specifically, the person image data displayed as the person image 321 is associated with the person image data stored in the text candidate database 104, and the acquired person name is included in the web text of the corresponding person image data in the text candidate database 104. If the text information is included, registration is possible, and the process proceeds to step S35. On the other hand, when the acquired personal name text information is not included in the web text, registration is impossible and the process proceeds to step S36.
In step S35, the text storage means 140 stores the registered person name text information as the person name text of the corresponding person image data in the person image database 102, and the process proceeds to step S36.
Thereafter, the operation is the same as in the first embodiment.

[Effects of Second Embodiment]
In the second embodiment described above, the following operational effects can be obtained in addition to the operational effects of the first embodiment.
The registration determination unit 131 associates the person image data displayed as the person image 321 of the authentication page 30 with the person image data stored in the text candidate database 104 as a criterion for determining whether or not to register in the person image database 102, and sets the text candidate. It is assumed that the acquired person name text information is included in the web text stored in the database 104. Since the web text is stored as text from the web page from which the image data is acquired by the image acquisition means 171 and the face extraction means 181, personal name text information is included in the web text. Therefore, a more appropriate person name for the person image data can be registered in the person image database 102. Therefore, more reliable data can be collected.

[Third Embodiment]
A third embodiment of the present invention will be described with reference to FIG.
FIG. 7 is a block diagram showing a schematic configuration of the authentication server in the third embodiment.
The authentication server 400 according to the third embodiment has the same configuration as that of the first embodiment except that the advertisement information database 105 is used instead of the authentication image database 101.

  For example, as shown in Table 5 below, the advertisement information database 105 has a table structure in which text that is attribute information related to an advertisement image is stored as one record for each advertisement image data for advertisement. As attribute information related to the advertisement image, the name of the product displayed in the advertisement image data is stored in text.

Further, since the operations of the text input request unit 113, the registration determination unit 133, and the authentication unit 153 are different from those in the first embodiment by using the advertisement information database 105, these will be described.
The text input request unit 113 transmits authentication page information for authenticating use of the service to the terminal device 300. On the authentication page 30 shown in FIG. 3, an authentication image 311 for performing image authentication, an authentication text input unit 312, a person image 321, and a person name input unit 322 are displayed. In the third embodiment, the advertisement image data stored in the advertisement information database 105 is displayed as the authentication image 311, and the name of the product displayed in the advertisement image data is input to the authentication text input unit 312.

The authentication unit 153 determines whether or not authentication is possible by comparing the authentication image and the authentication text with the advertisement information database 105. If the advertisement image data and the text corresponding to the advertisement information database 105 are stored, authentication is possible, and if not stored, authentication is impossible.
The authentication server 400 having the above configuration can collect the person names for the person images as text in the person image database 102 by the same operation as in the first embodiment. The advertisement information database 105 stores data based on advertisement information transmitted from an advertiser terminal (not shown) connected via the Internet 20.

[Effects of Third Embodiment]
In the third embodiment described above, the following operational effects can be obtained in addition to the operational effects of the first embodiment.
The authentication server 400 displays the advertisement image data as the authentication image 311 of the authentication page 30. Accordingly, since the advertisement is displayed as an image every time authentication is performed, the advertising effect can be improved. In particular, displaying an advertisement image on the authentication page 30 that is always displayed when using the service is easily noticeable to the user, and the advertisement effect is high. In addition, since the user inputs the text of the product name and the like, the effect of causing the user to recognize the advertising target is enhanced.

[Modification]
In addition, this invention is not limited to embodiment mentioned above, In the range which can achieve the objective of this invention, the deformation | transformation shown below is also included, for example.
For example, when there are a plurality of person image data for one person name text in the person image database 102, an image collection grouped by the person name text can be created. Further, a predetermined number of corresponding person image data may be extracted from such an image collection, and the plurality of person image data may be displayed as a list as the person image 321 of the authentication page 30. Thereby, since the user can browse a plurality of person images, it is easy to specify a person name for the person image 321. As a result, the authentication server 100 (400) can collect highly accurate data.

  Further, in the present application, “image” is a concept including not only a still image but also various moving images using interactive moving image file reproduction by a player browser plug-in of a web browser.

  Further, when face authentication is performed on an image collected from the Internet and a plurality of face images are detected, a region of the face image may be cut out to be an attribute information addition target. Thereby, attribute information can be given to each face image.

  The present invention can be used as an authentication device for authenticating various information services.
