Abstract

This method for permitting use of data in a data use promotion system 100 to which a plurality of edge devices (network cameras 1) are connected via a network 2 comprises the steps of: managing, in a device connected to the network 2, data-use-permitted-person information 32 in which data-use-permitted persons are registered; determining whether or not the data obtained by a sensor device (image sensor 11) includes human-action information pertaining to an individual or an action of the individual; and determining, when the data that includes human-action information exists, whether or not the individual is registered in the data-use-permitted-person information 32 and, when registered, permits the use of the data.

Description

Data usage promotion device, data usage permission method and data usage permission program

The present invention relates to a data use promotion device, a data use permission method, and a data use permission program for promoting the use of data obtained by a sensor device.

With the spread of so-called IoT, the number of sensor devices connected to networks is increasing, and it is expected that the number will increase explosively in the future. As a result, a huge amount of data can be acquired and accumulated, but the current situation is that it cannot be said that the effective use of these data is being achieved.
One of the reasons why the use of such data does not proceed well is the problem of handling personal information.
In relation to such a problem, in Patent Document 1, in the identification of a blacklist person, a common common feature amount is created from the face images of a plurality of blacklist persons, and the blacklist person is based on this common feature amount. The technology for identification is disclosed. The use of the blacklisted person's face image itself is difficult from the viewpoint of handling personal information, and it is anonymized in the form of "common features".

JP-A-2019-53381

For example, by using information based on images from a large number of network cameras, it is possible to acquire information on events occurring in real space in almost real time. As one of the usage examples, it is possible to use it for accident prevention or the like by obtaining information on a place that cannot be seen from one's own place through a network while the car is running.
However, for example, many people will be reflected in the image of the network camera installed on the street corner. If a person is reflected in the video (personal information is included in the data), its use is restricted, and even if there is a technically possible and useful usage, this cannot be actually done. Or, the original effect may not be obtained.
Even in the technique of Patent Document 1, if the face image itself of the blacklisted person can be used, more reliable identification is possible, but the means of anonymization by "common feature amount" must be taken. The result is that the identification accuracy that should be originally obtained cannot be obtained.
As can be understood from such an example, there is a problem that the handling of personal information becomes a bottleneck and it is difficult to effectively utilize the data.

Hereinafter, embodiments of the present invention will be specifically described with reference to the drawings. The following embodiment is an embodiment of the present invention, and does not limit the present invention to the scope thereof.

<Embodiment 1>
FIG. 1 is a block diagram showing an outline of the configuration of the data usage promotion system of the first embodiment according to the present invention.
The data usage promotion system 100 includes a network 2, a plurality of network cameras (data usage promotion device) 1 connected to the network 2, and a data usage permitter management device (data usage promotion device) 3.
The data usage promotion system 100 has a sensor device such as a network camera according to the concept described below, and data obtained by a device connected to the network is distributed and used via the network (for example, a network). It is a system for promoting (used by another information processing device 4 or the like connected to 2). Hereinafter, the new data usage environment realized by this system will be referred to as a "data usage promotion environment". The data usage promotion environment is a place where a common consensus has been reached that participants will be allowed to use data for the realization of a more advanced information society.

The network camera (data usage promotion device) 1 is a so-called edge device, which is an image sensor 11, a RAM 12 for recording data from the image sensor 11, a CPU 13 for performing various arithmetic processes, and data for the network 2. It is provided with a transmission / reception unit 14 that serves as an interface for transmission / reception of data, and a storage unit 15 (hereinafter, simply referred to as “data use permission person data 15”) in which data use permission person data is stored.
The data use permitter management device (data use promotion device) 3 is an information processing device such as a so-called server, and is a CPU 31 that performs various arithmetic processes and a storage unit 32 (a storage unit 32 that stores a data use permitter management table). Hereinafter, it is simply referred to as "data usage permitter management table 32"), and a transmission / reception unit 33 that serves as an interface for transmission / reception of data to / from the network 2.

FIG. 3 is a schematic view showing a data use permitter management table (data use permitter information) 32 included in the data use permitter management device 3.
The data use permitter management table 32 corresponds to the ID information of the data use permitter, the face image (or feature amount data for face recognition), and the number of times the data is used, which is information about the number of times the data is actually used. It is a attached table.
A "data use permitter" is a participant in a data use promotion environment who has permitted the use of video or image data (hereinafter simply referred to as "video" or "video data") in which he / she is photographed. For example, when walking on a street corner, if you see yourself in a network camera 1 (any device that is not limited to the device owned by the data user), you are allowed to use the image. Those who have registered in advance.
Participation in the data usage promotion environment, that is, registration of information in the data usage permitter management table 32 may be performed by any method. For example, a person who wishes to participate in the data usage promotion environment may access the website provided by the data usage permitter management device 3 to input necessary information and transmit facial image data, or a paper medium. Attach a photo of yourself to the application form in, and mail it to the administrator of the data use permitter management device 3, and the administrator who receives this will register the information in the data use permitter management table 32. It may be something like. If other services or systems already have necessary information such as face image data (for example, the My Number system in Japan), it is something that links with those systems (the other systems themselves). , Including one that functions as a data use permitter management device 3). For example, in Japan's My Number system, by providing an item to check the intention to participate in the data usage promotion environment, the data use permitter described below can be sent to a server or the like that has information based on the My Number system such as a face image. The function of the management device 3 may be provided.
The data use permitter management device 3 calculates face recognition feature amount data from the face image data of a person who wishes to participate in the data use promotion environment, and manages this in the data use permitter management table 32. Since the method of calculating the feature amount data for face recognition is not a main part of the present invention, the description thereof will be omitted here. Any method that can be applied to those skilled in the art as "calculation of feature amount data for face recognition" can be used. The calculation of the feature amount data for face recognition in the data use permitter management device 3 is for the purpose of reducing the amount of data communication and improving the processing efficiency, but if the processing resources allow, the data use permission The data held as the person management table 32 or the data use permitter data 15 described below may be the face image data as it is.

FIG. 2 is a flowchart showing an outline of processing operations in the network camera 1. Further, FIG. 5 is a flowchart showing an outline of the processing operation in the data use permitter management device 3.
In step 201 (FIG. 2), the network camera 1 determines whether or not it is the update time of the data use permitter data 15, and if it is the update time, the data use permitter management device 3 is notified. , Request to update the data usage permitter data 15 (step 202). In response to this, the data use permitter management device 3 performs a process of distributing the difference information between the data use permitter management table 32 and the data use permitter data 15 possessed by the network camera 1 to the data use permitter data 15. (Fig. 5: Step 502 → Step 505).
FIG. 4 is a schematic view showing data use permitter data 15 possessed by the network camera 1. The data use permitter data 15 is a table in which the ID information of the data use permitter and the face image (feature amount data for face recognition) are associated with each other, and the process of step 202 is the data use permitter management device. The data is updated in correspondence with the data usage permitter management table 32 of 3. That is, when there is updated data in the data use permitting person management table 32 (when there is a new participant or a withdrawal person), this is reflected.
The update interval of the data use permitter data 15 may be arbitrary (naturally, the update interval is preferably short, but it may be appropriately determined according to the capacity of the network, the processing capacity of each device, and the like. Good).

In step 203, it is determined whether or not the network camera 1 has detected a person. The determination is made based on the video data captured by the image sensor 11, and the content of the technique of "detecting a person based on the video" itself is not a main part of the present invention. Omit. Any method can be used by those skilled in the art that can be applied as "video-based human detection".
When a person is detected, it is determined whether or not the person is a "data use permitter" (step 203 → step 204). The determination is performed by collating the video data captured by the image sensor 11 with the face recognition feature amount data of the data use permitter data 15. The specific contents of face recognition in the video data captured by the image sensor 11 and collation with the feature amount data for face recognition of the data use permitter data 15 are not the main parts of the present invention. The explanation is omitted. Any method that can be applied by those skilled in the art as "face recognition" or "face matching" can be used.

If it is not possible to determine that the person is a "data use permitter" by the determination process in step 204, the process proceeds to step 205 to perform mosaic processing on the area of the person in question in the video data. This process is for anonymizing the video of the person concerned when it cannot be determined that the person is a "data use permitter", and is not limited to the mosaic process but is an arbitrary anonymization process. Good (any method that one of ordinary skill in the art can apply as an "anonymization process" can be used).
Even if a person is detected in step 203, but face recognition cannot be performed, and as a result, it cannot be determined that the person is a "data use permitter", the process proceeds to step 205 to perform anonymization processing.

In step 206, a process of converting into metadata is performed based on the video data captured by the image sensor 11.
That is, the information obtained based on the image of the person in the picture is analyzed and earned (for example, the acquisition of the information obtained by performing the behavior analysis or the facial expression analysis). Since the content of the technique of "metadata conversion" itself is not a main part of the present invention, the description thereof is omitted here. Any method that can be applied as "metadata" by those skilled in the art can be used.
The video that has been anonymized in step 205 is also converted into metadata in step 206. Basically, there is almost no information that can be metamorphosed, but at least it is possible to obtain information that "there are people". As a result, it is possible to use the information that "there is a person in the blind spot" to help prevent accidents. Here, as an example, the video that has been anonymized is also meta-ized (that is, the information is used after being anonymized even if it cannot be determined that the person is a "data user"). Meta-ization based on the anonymized video may not be performed. In this case, the anonymization process in step 205 is not particularly necessary in the first place, and it is sufficient to prevent meta-metaization from the video portion that could not be determined to be the “data use permitter”.

In the following step 207, a process of transmitting the metadata obtained in step 206 to another device (information processing device 4 or the like) on the network 2 is performed. It is arbitrary to which device the metadata is transmitted, and for example, the metadata may be transmitted to a site that stores various data in order to provide the corresponding data as needed. However, in order to provide services in near real time, metadata may be transmitted to a site that sequentially analyzes events occurring in the real space.
By using metadata based on video data as the data to be transmitted, the amount of communication can be reduced and the congestion of the network 2 can be suppressed.

In step 208, the process of transmitting the ID information of the data use permitter determined in step 204 to the data use permitter management device 3 is performed. In response to this, the data use permitter management device 3 performs a process of adding the number of times of data use of the corresponding ID in the data use permitter management table 32 (FIG. 5: step 501 → step 504).
When it is time to process the payment of the consideration to the data use permitter, the data use permitter management device 3 performs the payment process of the consideration according to the number of times of data usage of each ID (data use permitter) (step 503). → Step 506).
Various methods can be considered for payment of the consideration, as long as the data licensee can evaluate it as the consideration. The direct consideration is monetary payment, which is to transfer the amount determined according to the number of times data is used to a designated bank account (registered in the data usage permitter management table 32), or on the network. It is conceivable to give points that can be used to purchase services and goods provided by.
In addition, as payment of consideration, it is conceivable to provide more advanced services using various knowledge obtained from the data obtained by the data use promotion environment only to the data use licensee. In this case, since the consideration is paid by providing the service, the payment process of the consideration in steps 503 and 506 is not necessary (of course, the consideration may be paid in addition to the service provision).
In addition, although the example in which the payment processing of the consideration is periodically performed at a predetermined time is taken as an example, even if the payment processing is performed at any time when the data usage information is received in step 501, etc. Good.

As described above, according to the data usage promotion system 100 of the present embodiment, it is possible to create a new environment for promoting the use of data. In other words, it is a mechanism to properly pay the compensation to the individual who is the basis of the data (not only when the data is consciously provided but also when it is reflected in the camera without knowing it). By obtaining the agreement in advance, it is possible to make effective use of the data.

In the present embodiment, the network camera has been described as an example (that is, an image sensor is used as an example of the sensor device), but the present invention is not limited to this, and can be obtained from any sensor device connected to the network. The concept described above can be applied as a process for data.
The image of the face taken by the camera is "identification information that can identify an individual". At the same time, it is also "person / behavior information regarding an individual or an individual's behavior". "Person / behavior information regarding an individual or an individual's behavior" means all information regarding an individual or an individual's behavior that can be acquired by a sensor device. For example, the physical information of an individual acquired by a sensor device is "information about an individual" regardless of whether or not the information can identify the individual, and is obtained based on the behavior of the individual such as purchasing. The information received is "information about individual behavior".
The "identification information" is information that can identify an individual by the information, and is, for example, a unique physical feature such as an iris, a voiceprint, a fingerprint, or a unique motion feature such as a walking pattern. On the other hand, "person / behavior information" refers to all information that can be acquired by a sensor device more comprehensively based on an individual or an individual's behavior.

The processes of steps 203 to 208 are executed every time a person is identified in the image captured by the image sensor 11. That is, when a plurality of people are reflected in the image, the processes of steps 203 to 208 are executed for each of the reflected persons. That is, "when the data includes the person / behavior information of an individual who is not the person who is not authorized to use the data, the person / behavior information or the identification information is deleted or anonymized, and then the data is obtained. It is intended to "permit use", and "when the data contains the person / behavior information of a plurality of individuals, and any of the plurality of individuals is not the data use permitter". , The use of the data is permitted after deleting or anonymizing the person / behavior information of the individual who is not the authorized person to use the data.
In addition, "when the data includes the person / behavior information of a plurality of individuals, the data including the person / behavior information only when all of the plurality of individuals are authorized to use the data. It may be "permitting the use of". Alternatively, "if the data includes the person / behavior information of an individual who is not the person authorized to use the data, the data is deleted".

In the present embodiment, as an example of payment of consideration, when metadata based on personal video data is uploaded, "data is used" is taken as an example, but data to be paid of consideration. The concept of "use" is not limited to this. For example, meta-metaization can be treated as "use", and conversely, meta-uploading is not treated as "use", and the information is actually used to generate economic benefits. It may be treated as "use" for the first time.

In the present embodiment, meta-metaization of data is taken as an example, but meta-metaization is not an essential requirement of the concept of the present invention. The present invention can also be applied when the data obtained from the sensor device is used as it is without being metamorphized.

In the present embodiment, in the network camera 1 which is an edge device, the CPU 13 that executes the process of FIG. 2, the data use permitter data 15, and the like are asked, "Whether the data obtained by the sensor device has person / action information. "Person / behavior information determination unit that determines whether or not" or "when there is data containing person / behavior information, it is determined whether or not the individual is a data use permitter, and the data use permission In the case of a person, an example is one that functions as a "data use permission unit" that permits the use of data including the person / behavior information.
Further, in the data use permitter management device 3, the CPU 31 that executes the process of FIG. 5, the data use permitter management table 32, and the like "manage the data use permitter information in which the data use permitter is registered". An example is one in which a function or a function of "giving consideration information to an individual" is configured.
With respect to each of the above processing functions, which processing is performed by which device can be appropriately selected, and does not make a difference as a concept of the present invention. A device that performs a part or all of these processes is a "data usage promotion device".
For example, a process of "determining whether or not the data obtained by the sensor device has person / behavior information" or "when there is data including person / behavior information, the individual permits the use of the data". The process of "determining whether or not the person is a person" may be performed by another device on the network (inquiring to an external device), and the edge device may receive the determination result.
As an example of such a system, a system for inquiring whether or not the edge device is a data use permitter to an external device will be described as the second embodiment below.

<Embodiment 2>
FIG. 6 is a block diagram showing an outline of the configuration of the data usage promotion system of the second embodiment. The same reference numerals are used for those having the same concept as in the first embodiment, and the description here will be omitted or simplified.
In the data usage promotion system 100'of the present embodiment, the network camera 1'inquires whether or not the person shown in the image is a data usage permitting person to the data usage permitting person management device 3', which is an external device. It is a system.

The network camera (data usage promotion device) 1'of the present embodiment has the same configuration as the network camera 1 of the first embodiment except that the data usage permitter data 15 is not provided.
The data usage permitter management device (data usage promotion device) 3'of the present embodiment is operated by a mobile phone operator, and is a mobile terminal including an individual identification number and location information of a mobile terminal (mobile phone, smartphone, etc.). It has data 34. Others have basically the same configuration as the data use permitter management device 3 of the first embodiment, but the individual identification number is associated with the ID information of the data use permitter management table 32. Further, in the data use permitter management table 32 of the present embodiment, the data use permitter face image (feature amount data for face recognition) is not particularly required.

FIG. 7 is a flowchart showing the outline of the processing operation in the network camera 1', and FIG. 8 is a flowchart showing the outline of the processing operation in the data use permitter management device 3'. The same reference numerals are used for those having the same processing concept as that of the first embodiment, and the description here is omitted or simplified.

The network camera 1'does not have the data use permitter data 15 in the first embodiment, and therefore does not have the update processing of steps 201 and 202 in the first embodiment (FIG. 2).
When the network camera 1'detects a person (FIG. 7: step 203), the data use permitter management device 3'inquires whether or not the person is a data use permitter (step 701).
Upon receiving this, the data use permitting person management device 3'determines whether or not the person is a data use permitting person, and returns this to the network camera 1'(FIG. 8: step 801 → step 802).

The network camera 1'has the position information of its own installation position, and transmits this to the data use permitter management device 3'at the time of inquiring in step 701. Alternatively, since the data use permitter management device 3'has the position information of each network camera 1', the data use permitter management device 3'determines the position where the network camera 1'is installed. It is possible. It is more desirable that the configuration is such that it is possible to discriminate from, for example, information on the orientation and angle of view of the camera to position information indicating the imaging range of the network camera 1'.
In addition, the data use permitter management device 3'can determine whether or not the mobile terminal exists at the corresponding position by referring to the mobile terminal data 34. Since the individual identification number of the mobile terminal is associated with the ID information of the data use permitter management table 32, the data use permitter is located at the position of the network camera 1'(more preferably within the imaging range of the network camera 1'). It is possible to determine whether or not the person who has made an inquiry from the network camera 1'is a data use permitter.
In this way, it is possible to determine whether or not the person is authorized to use the data without using the data (here, the image of a person) obtained by the sensor device itself.

The data use permitter management device 3'returns the determination result of whether or not the user is a data use permitter to the network camera 1'(FIG. 8: step 802), and if the person is a data use permitter, the corresponding ID The process of adding the number of times the data has been used is performed (step 803: Yes → step 504). On the other hand, if the user is not the data licensee, step 504 is skipped. The payment process (steps 503 and 506) of the data usage permitter management device 3'is the same as that of the first embodiment.
Further, the subsequent processing (FIG. 7: steps 204 to 207) in the network camera 1'that has received the determination result of whether or not the person is authorized to use the data is the same as in the first embodiment. However, since the process of uploading the data usage information in step 208 of FIG. 2 is not necessary, it is not performed here.

As described above, according to the data usage promotion system 100'of this embodiment, it is not necessary for the network camera 1'to have the data usage permitter data 15, and therefore there is no need for processing to update the data usage permission person data 15. In addition, it is not necessary to perform processing such as pattern recognition and pattern matching for determining whether or not the user is authorized to use the data. Therefore, the resources required for the data usage promotion system 100'can be reduced.

In the present embodiment, in the network camera 1'which is an edge device, the CPU 13 that executes the process of FIG. 7, the transmission unit 14, and the like "when there is data including person / behavior information, the individual , Configure the function to "inquire to the external device whether or not the person is authorized to use the data".
Further, in the data use permitter management device 3', the CPU 31 that executes the process of FIG. 8, the data use permitter management table 32, the mobile terminal data 34, and the like are described as "data use permission in which the data use permitter is registered. Data use permitter determination unit that has person information, determines whether or not the individual is registered in the data use permitter list information in response to the inquiry, and returns the determination result as a reply to the inquiry. It functions as ".

As described above, which processing is performed by which device can be appropriately selected, and does not differ from the concept of the present invention.
For example, in the present embodiment, the data use permitter management device 3 has a function of managing data use permitter information (data use permitter management table 32) and a function of giving consideration information or performing consideration payment processing. However, information on these may be managed by the distributed ledger technology using the blockchain. Transaction information and settlement information when the data enabled based on the concept of the present invention described above are traded between specific devices may be managed by a blockchain. In addition, the information (ID and feature amount data for face recognition) of the data use permitter may be managed by the blockchain. This is to prevent falsification of the information of the data licensee.
That is, a P2P type network is formed in the devices connected to the network (in the example of the embodiment, the network camera 1, the data usage permitter management device 3, and the other information processing device 4), and the concept of the present invention described above is described. The processing based on the above may be performed.

In each of the above embodiments, the CPU executes the processes described above based on various data and the like, that is, the person / behavior information discrimination unit and the data use permission unit are configured by the CPU and the software executed therein. However, the present invention is not limited to this. Each functional unit may be integrally or individually configured by a dedicated circuit or the like. Whether each processing function is configured in hardware as a dedicated circuit, configured in software on a general-purpose circuit, or a combination thereof can be appropriately selected.
Further, in each of the above embodiments, the edge device includes the sensor device as an example, but it goes without saying that the so-called gateway device and the sensor device may be separate bodies.

In each of the above embodiments, the manifestation of intention of the data use permitter is only whether or not to permit the use of the data, but various conditions may be added to the use of the data.
For example, conditioning for meta-ization, conditioning for the purpose of use, conditioning for consideration, and the like may be made.
Conditioning for meta-ization is, for example, disabling extraction (meta-ization) of specific information such as gender and race, and the condition is the data use permitter management table 32 or data use permitter. It is set in the data 15, and the processing according to the conditions is performed at the time of the meta-processing.
The conditions for the purpose of use and consideration include, for example, permitting the use of only the traffic management system, and permitting the use only when the consideration above a predetermined value can be obtained. For example, for these conditions, index information may be added to the metamorphized data so that only the data satisfying the conditions can be used.
