Description

The present invention relates to a communication relay device, a system, a method and a program, and more particularly to a communication relay device, a system, a method and a program for relaying transmission of image data including a person to a public server.

In recent years, image data of photographs taken with mobile phones, digital cameras, and the like are often published on the Internet. Therefore, there is a risk that an individual may be identified from the published image data. Therefore, in Patent Document 1, it is difficult to identify personal information by performing mosaic processing on the face area in the image data and performing predetermined processing on the attribute information added to the image data. Techniques relating to devices for creating image files are disclosed.

In addition, smartphones and personal computers use biometric authentication such as fingerprint authentication to realize security functions. For example, Patent Document 2 discloses a technique relating to an authentication device that authenticates an individual using the characteristics of a living body.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. In each drawing, the same or corresponding elements are designated by the same reference numerals, and duplicate explanations are omitted as necessary for the sake of clarity of explanation.

<Embodiment 1>
Here, the problem to be solved by this embodiment will be described again. First, FIG. 7 is a diagram for explaining the concept of uploading a captured image according to the related technology. The mobile terminal 90 is an information terminal equipped with a digital camera function. Then, the mobile terminal 90 photographs the user U and stores it as a captured image 91 in an internal storage area (not shown). Here, the captured image 91 includes the user U so as to be visually identifiable. Further, it is assumed that the captured image 91 has a higher resolution than the screen resolution of a general display device. After that, the mobile terminal 90 uploads the captured image 91 to the public server 94 in order to publish it on SNS or the like. Specifically, the mobile terminal 90 transmits an upload request including the captured image 91 to the HGW (Home Gateway) 92 wirelessly connected to the mobile terminal 90. Upon receiving the upload request, the HGW 92 transfers the upload request including the captured image 91 to the public server 94, which is the transmission destination, via the Internet N. The public server 94 receives an upload request for the captured image 91 via the Internet N, and stores the captured image 95 in an internal storage device (not shown). After that, the mobile terminal 96 transmits a viewing request for the captured image 95 to the public server 94 via the Internet N by the operation of the user V. The public server 94 returns the captured image 95 to the mobile terminal 96 in response to the viewing request from the mobile terminal 96. As a result, the mobile terminal 96 displays the captured image 95 on the screen, so that the user V (who is different from the user U) of the mobile terminal 96 can view the captured image 95.

FIG. 8 is a diagram for explaining the occurrence of a problem. As described above, the captured image 95 includes the user U, and in particular, the hand of the user U is captured. Further, as described above, the captured image 95 has a higher resolution than the screen resolution of a general display device. Therefore, it is assumed that the captured image 95 is a fine image of not only the upper body including the face of the user U but also the fingerprint of the fingertip.

Therefore, the user V enlarges the area of the hand from the captured image 95 and displays the enlarged image 951 of the hand on the screen by using the mobile terminal 96 or another computer, and further, from the enlarged image 951 of the hand. The fingertip region is enlarged and extracted as an image 952 of the fingertip region. Here, it is assumed that the image 952 of the fingertip region contains the fingerprint of the user U in such detail that it can be used as fingerprint authentication data. Then, the image 952 of the fingertip area is stored in the mobile terminal 96. That is, the user V may be able to forge the fingerprint information of the user U from the captured image 95 published by the public server 94. Then, for example, the user V holds the screen of the mobile terminal 96 over the fingerprint authentication device in which the user U is officially registered while displaying the image 952 of the fingertip area on the screen of the mobile terminal 96. , There is a possibility of being authenticated as user U. That is, the user V may impersonate the user U and break through the security. This may become more prominent as the resolution of the photographing apparatus increases in the future. In particular, the fingerprint information cannot be visually identified by the user U simply by displaying the captured image 11 on a normal screen, so that there is little recognition that the captured image 11 contains biometric information when the captured image 11 is captured. Therefore, it is more dangerous. Further, once the captured image 95 is leaked onto the Internet N, it is easily diffused, so that it is difficult to erase all the captured images 95 after the diffusion. Further, since the fingerprint is information unique to the living body unlike the ID data, it cannot be changed, and the leakage of the fingerprint information can be a serious security problem. The first embodiment has been made to solve such a problem, and will be described below.

FIG. 1 is a block diagram showing a configuration of a communication relay system 1000 according to a first embodiment of the present invention. The communication relay system 1000 includes a communication terminal 10, a communication relay device 20, and a public server 30. The communication terminal 10 holds a captured image 11 including a person. Further, the communication terminal 10 transmits a transmission request for transmitting the captured image 11 to the public server 30 to the communication relay device 20.

The communication relay device 20 relays communication between the communication terminal 10 and the public server 30. The communication relay device 20 includes a receiving unit 21, a specific unit 22, a processing unit 23, and a transmitting unit 24. The receiving unit 21 receives a transmission request for transmitting the captured image 11 from the communication terminal 10 to the public server 30. The identification unit 22 identifies a specific area from the captured image 11 included in the received transmission request.

Here, the specific area is an area of the body of a person that can be used for predetermined biometric authentication, and the person cannot be visually identified. The predetermined biometric authentication is, for example, fingerprint authentication or iris authentication. The specific area is, for example, a fingertip area containing fingerprint information used in fingerprint authentication, an eye area containing iris information used in iris authentication, and the like. Further, the specific area is a fine area in which, when the photographed image 11 is displayed on the screen of a normal display device, a person cannot be visually identified in general. For example, when a person is included in the photographed image 11, a person who browses the photographed image 11 on the screen usually visually identifies the person in the photographed image 11 by a face or body shape including a facial expression and a hairstyle. On the other hand, humans cannot visually identify the person included in the captured image 11 on the screen by fingerprints or irises. Therefore, even if the captured image 11 is captured at a resolution that allows fingerprints and irises to be identified, the fingertip region and the eye region can be said to be specific regions in which a person cannot be visually identified. Furthermore, when the image size is such that the face can be visually identified, the fingertip region and the eye region in the image are fine.

The processing unit 23 performs a predetermined processing process on a specific area of the captured image 11. Here, the predetermined processing is, for example, correction with similar colors for a specific area, change of the ratio of the size of parts, and the like, but is not limited thereto. The predetermined processing may be processed to such an extent that it cannot be visually identified when the specific area is enlarged and displayed on the screen. The transmission unit 24 transmits the processed image that has been processed to the public server 30 in place of the captured image 11.

The public server 30 holds the processed image received from the communication relay device 20, and returns the processed image in response to a viewing request for the processed image. That is, the public server 30 publishes the processed image to the outside. The public server 30 is, for example, a server that manages contents such as SNS (Social Network Service).

FIG. 2 is a sequence diagram showing the flow of the communication relay method according to the first embodiment of the present invention. First, the communication terminal 10 transmits a transmission request for the captured image 11 to the public server 30 to the communication relay device 20 (S101). In response to this, the receiving unit 21 of the communication relay device 20 receives the transmission request from the communication terminal 10. Then, the specific unit 22 of the communication relay device 20 specifies a specific area from the captured image 11 included in the transmission request (S102). Subsequently, the processing unit 23 of the communication relay device 20 performs a predetermined processing process on a specific area of the captured image 11 (S103). After that, the transmission unit 24 of the communication relay device 20 transmits the processed image to which the processing has been performed to the public server 30 (S104). That is, the communication relay device 20 does not transmit the captured image 11 to the public server 30. Then, the public server 30 can publish the received processed image to the outside.

As described above, since the specific area has been processed in the processed image according to the first embodiment, even if the specific area is disclosed to the outside by the public server 30, the content of the specific area is not leaked, and a predetermined biometric authentication is performed. Forgery of data can be suppressed. Further, since the specific area is originally an area in which a person cannot be visually identified, even if it is processed, there is little influence on the decrease in visibility by human eyes. That is, it is possible to prevent forgery of biometric authentication data while maintaining the visibility of publicly available image data including a person.

<Embodiment 2>
The second embodiment is an improved example of the first embodiment described above. In particular, the specific unit specifies an area including either the fingertip or the eye of the person as the specific area. As a result, forgery of authentication data in biometric authentication of fingerprint authentication or iris authentication can be suppressed.

Then, the processed portion may be corrected so that the specific region has a similar color. Alternatively, the processed portion may change the ratio of the sizes of a plurality of portions included in the specific region. These make it difficult to identify a specific area in the processed image, and can prevent forgery even in a high-resolution image.

Further, it is desirable to further include a determination unit for determining the network type to which the destination of the transmission request belongs, and the identification unit specifies the specific area when the determined network type is an external network. As a result, when the transmission destination is the internal network, the captured image can be transmitted as it is without processing, so that the visibility in the safe internal network can be further maintained.

Further, the communication relay device is a home gateway device, and the receiving unit may receive the transmission request from a communication terminal under the control of capturing the captured image. As a result, it is possible to deal with general usage patterns.

FIG. 3 is a block diagram showing the configuration of the communication relay system 2000 according to the second embodiment of the present invention. The communication relay system 2000 includes a mobile terminal 10a, a mobile terminal 10b, an HGW 20a, an Internet N, a public server 30, and a mobile terminal 32. Internet N is an example of an external network.

The mobile terminals 10a, 10b and 32 are, for example, smartphones, mobile phones, tablet terminals and the like equipped with a digital camera. The mobile terminals 10a, 10b and 32 may be information processing devices such as a personal computer (PC).

Here, the mobile terminal 10a is an example of the communication terminal 10 described above. The mobile terminal 10a holds a photographed image 11 of the user U in an internal storage area (not shown). Here, the captured image 11 includes the user U so as to be visually identifiable. Further, it is assumed that the captured image 11 has a higher resolution than the screen resolution of a general display device. Therefore, it is assumed that the captured image 11 includes the face or body shape of the user U in a visually identifiable manner, and the fingerprint of the fingertip of the user U's hand is also finely imaged.

The HGW 20a is an example of the above-mentioned communication relay device 20, and is a home gateway device that relays communication between the mobile terminals 10a and 10b and the Internet N side. Further, the HGW 20a is connected to each of the mobile terminals 10a and 10b by a wireless LAN (Local Area Network). That is, the mobile terminals 10a and 10b are under the control of the HGW 20a. Further, the HGW 20a, the public server 30, and the mobile terminal 32 are connected via the Internet N.

The HGW 20a further includes a determination unit 25 in addition to the configuration of the communication relay device 20. The determination unit 25 determines whether the network type to which the destination of the transmission request belongs is the Internet N or the wireless LAN. Then, the specific unit 22 specifies a specific area from the captured image 11 when the determined network type is the Internet N. The processing unit 23 corrects the specific region so that it has a similar color, and generates a processed image. The transmission unit 24 transmits the generated processed image to the public server 30 via the Internet N. The public server 30 stores the received processed image 31 in an internal storage device (not shown).

FIG. 4 is a flowchart showing the flow of the communication relay method according to the second embodiment of the present invention. First, the receiving unit 21 of the HGW 20a receives the upload request of the captured image 11 from the mobile terminal 10a (S201). Next, the determination unit 25 of the HGW 20a determines whether or not the network type to which the destination of the upload request belongs is the Internet N (S202). At this time, if it is determined that the network type is not the Internet N but the wireless LAN, the transmission unit 24 of the HGW 20a transmits the upload request including the captured image 11 as it is to the destination in the wireless LAN, for example, the mobile terminal 10b ( S208). Therefore, the mobile terminal 10b can receive the captured image 11 via the wireless LAN and display the captured image 11 on the screen. Since the mobile terminals 10a and 10b exist in the same HGW 20a, even if the user W views the captured image 11 as it is from the screen of the mobile terminal 10b, the security risk is low.

On the other hand, when it is determined in step S202 that the network type is Internet N, the determination unit 25 determines whether or not a person is included in the captured image 11 included in the upload request (S203). For example, the determination unit 25 determines whether or not the captured image 11 includes a region corresponding to a person by executing a known image recognition process on the captured image 11. When it is determined in step S203 that a person is included in the captured image 11, the determination unit 25 determines whether or not the photographed image 11 includes a fingertip (S204). For example, the determination unit 25 determines whether or not the captured image 11 includes a region corresponding to a fingertip by executing a known image recognition process on the region corresponding to the person in the captured image 11. ..

When it is determined in step S204 that the photographed image 11 includes the fingertip, the specific unit 22 determines whether or not fingerprint authentication is possible with the image of the fingertip region in the photographed image 11 (S205). For example, the specific unit 22 extracts a fingertip region from the captured image 11 and determines whether or not the image of the extracted fingertip region is larger than the resolution of the input data in the predetermined fingerprint authentication process. Then, when the image of the fingertip region is equal to or higher than the resolution, it is determined that fingerprint authentication is possible with the image of the fingertip region in the captured image 11.

When it is determined in step S205 that fingerprint authentication is possible with the image of the fingertip region in the captured image 11, the processing unit 23 corrects the fingertip region of the captured image 11 with a similar color to generate a processed image. (S206). Then, the transmission unit 24 transmits the corrected processed image to the destination via the Internet N (S207).

Therefore, the public server 30 receives the upload request of the processed image via the Internet N and stores it as the processed image 31 in the internal storage device (not shown). After that, the mobile terminal 32 transmits a viewing request for the processed image 31 to the public server 30 via the Internet N by the operation of the user V. The public server 30 returns the processed image 31 to the mobile terminal 32 in response to the viewing request from the mobile terminal 32. As a result, the mobile terminal 32 displays the processed image 31 on the screen, so that the user V of the mobile terminal 32 can view the processed image 31. Since the fingertip region in the processed image 31 is corrected with a similar color, the user V cannot forge the fingerprint information of the user U from the processed image 31.

If any of steps S203, S204, or S205 is determined to be NO, the transmission unit 24 transmits the captured image 11 to the destination via the Internet N (S209). In this case as well, the public server 30 holds the received photographed image 11 inside, and returns the photographed image 11 to the requester in response to the viewing request. However, in this case, the captured image 11 does not have the fingerprint of the fingertip region imaged at least at a resolution at which fingerprint authentication is possible. Therefore, even if the captured image 11 is released as it is, the possibility that the fingerprint authentication data is forged is low. On the other hand, since the processing is not performed, the visibility is not excessively lowered.

FIG. 5 is a diagram for explaining the effect according to the second embodiment of the present invention. Here, the case where YES is determined in step S205 described above will be described. In this case, the processed image 31 includes the user U, and in particular, the hand of the user U is shown. Therefore, the user V who has stored the processed image 31 in the mobile terminal 32 enlarges the hand area of the processed image 31 and displays the enlarged hand image 311 on the screen, and further, the fingertip area from the enlarged hand image 311. Is enlarged and extracted as an image 312 of the fingertip region. However, since the image 312 in the fingertip region is corrected with a similar color, no fingerprint information is left, and at least it is unclear. Therefore, it is shown that the fingerprint information for fingerprint authentication cannot be forged using the processed image 31, and the security of fingerprint authentication cannot be breached by using the image 312 in the fingertip area.

Subsequently, a modified example of the second embodiment will be described. In the above, the fingertip area included in the captured image 11 is set as a specific area as a specific area, and measures against fingerprint authentication are shown as biometric authentication, but the biometric authentication targeted in the present embodiment is not limited to this. For example, FIG. 6 shows the relationship between the type of biometric authentication and biometric information. Here, as the types of biometric authentication, fingerprint authentication, vein authentication, face authentication, bill authentication, iris authentication, and voiceprint authentication are mentioned. Here, since the purpose of this embodiment is to suppress forgery of biometric information from a photographed image including a person, vein authentication and voiceprint authentication that cannot be extracted from the image are excluded. The measures against fingerprint authentication are as described above.

Next, measures for iris recognition will be described. Here, the iris authentication is performed by using the iris information in the eye. Since the iris information is also very fine like the fingerprint information, it can be realized by applying the eye region included in the captured image 11 as a specific region to the present embodiment.

In addition, measures for face recognition will be described. Here, face recognition is performed by using the shape of a person's face, facial expression, hairstyle, or the like. However, even if the captured image 11 includes a face, if a person can visually identify the person when displayed on the screen of a normal display device, the user can use the personal information before uploading. Since it is possible to notice the risk of outflow, it is possible to take some measures regardless of the present embodiment. However, even if the captured image 11 includes a face, if the photographed image 11 is very small and the person cannot be visually identified on the screen of a normal display device, the user can upload the captured image 11 for personal information. It is hard to notice the outflow of. In particular, when the captured image 11 has a higher resolution than the screen resolution, the face region of the captured image 11 is clear even if it is extracted, so that it may be forged as face recognition data. Therefore, such a case can be realized by applying the facial region included in the captured image 11 as a specific region to the present embodiment. Then, as the processing in this case, since a plurality of parts of the face are included in the specific area, by changing the ratio of the sizes of the parts, processing is performed so that the person is recognized as another person in the face authentication. You may.

In addition, measures for bill authentication will be described. Here, the bill authentication is performed by using the shape of the hand, the palmistry, or the like. In this case, it can be realized by applying the hand region included in the captured image 11 as a specific region to the present embodiment. Then, by changing the ratio of the thickness and length of a plurality of parts of the hand, that is, the thumb, index finger, etc., to a specific area, processing may be performed so that the person is recognized as another person in the bill authentication. Alternatively, the palmistry of the palm may be corrected with a similar color.

From the above, according to the second embodiment, it is possible to suppress forgery of biometric authentication data while maintaining the visibility of the image data published via the network. In particular, since it is not the face mosaic processing that is originally visually identifiable, but the processing of the portion that has little influence on the user's visual inspection, it is possible to reduce the discomfort of the user and maintain the visibility. Further, even if the image data has a high resolution, the region that can be used for biometric authentication is processed, so that the forgery of the biometric authentication data can be suppressed and spoofing can be prevented. Further, since the processing is performed in the communication relay device when transmitting the captured image to the public server, the original image in the photographing device main body is retained. Further, since the processing is performed in the communication relay device, leakage of biological information can be suppressed even when the sender user is not aware of it. Then, as long as it is processed when it is transmitted from the communication relay device to the external network and shared within the internal network that is not open to the outside, it is not processed, so that the visibility can be further maintained.

<Other Embodiments>
In the above-described embodiment, not only the captured image but also the metadata added to the captured image, for example, GPS information indicating the photographing location, may be deleted in the processing. This can be expected to further improve security.

The present invention is not limited to the above embodiment, and can be appropriately modified without departing from the spirit.

Further, in the above-described embodiment, the present invention has been described as a hardware configuration, but the present invention is not limited thereto. The present invention can also realize arbitrary processing by causing a CPU (Central Processing Unit) to execute a computer program.

In the above example, the program can be stored and supplied to a computer using various types of non-transitory computer readable media. Non-transitory computer-readable media include various types of tangible storage media. Examples of non-temporary computer-readable media include magnetic recording media (eg, flexible disks, magnetic tapes, hard disk drives), magneto-optical recording media (eg, magneto-optical disks), CD-ROMs (Read Only Memory), CD-Rs, Includes CD-R / W, DVD (Digital Versatile Disc), semiconductor memory (for example, mask ROM, PROM (Programmable ROM), EPROM (Erasable PROM), flash ROM, RAM (Random Access Memory)). The program may also be supplied to the computer by various types of transient computer readable media. Examples of temporary computer-readable media include electrical, optical, and electromagnetic waves.
