<< 1. First embodiment >>
<1-1. Background>
Currently, surveillance cameras are installed everywhere in the town, and the number of surveillance cameras has been increasing in recent years. It is expected that the number will increase more and more in the future. By using images obtained from these surveillance cameras, various information can be obtained, and people's lives can be made safer, more comfortable and richer.

  For example, an image obtained from a surveillance camera can be used to detect criminal behavior at an early stage, or to detect a sign of the crime to prevent criminal behavior before it occurs. In addition, the image obtained from the camera can be used for finding a disaster, an accident, or the like and for investigating the cause.

  It is also conceivable to distribute an image obtained from the surveillance camera to a user other than the installer of the monitor camera. For example, when a child is provided with an IC tag and the tag information of the child is read by an IC tag reader connected to the surveillance camera, an image taken by the surveillance camera is distributed to a parent of the child. It is also conceivable to use it for watching over schools.

  The application of the surveillance camera as described above can be realized, for example, simply by a person checking the image of the camera, or can be realized by an image analysis technique performed by the information processing apparatus.

  As described above, various applications can be considered by using images obtained from surveillance cameras, but currently, images obtained from surveillance cameras are often used only for limited purposes such as crime prevention purposes. . As a reason that the above application is difficult to be performed, for example, there are problems of privacy infringement and security deterioration.

  For example, if an image obtained by the surveillance camera is provided to a user other than the installer, when the surveillance camera is shooting a person, privacy of the person may be violated. For example, information about when and where the person was and what the person was doing can be visually confirmed by the user.

  Also, if information such as a security gap can be confirmed from an image obtained by the surveillance camera, if the image is provided to a malicious user such as a criminal, the security level (security) may be reduced. is there.

  Regarding the above-mentioned problem, for example, Patent Literature 1 discloses a technique capable of protecting the privacy of a person whose personal information is registered by transmitting a different image depending on authentication result information. . Further, Patent Literature 2 discloses a technology for protecting a privacy of a person who is not a watching target by detecting a non-target object that is not a watching target and performing a masking process. Patent Document 3 discloses an image distribution system in which an image is divided into a foreground and a background for each person and transmitted, and the receiving apparatus generates the image, thereby reducing the amount of distribution data and protecting privacy. I have.

  However, according to the technology described in Patent Document 1, privacy can be protected by changing a video to be distributed according to an individual identification result, but it is not possible to cope with a case where a plurality of persons are reflected on a camera. There is. For example, if a person whose personal information is registered in advance and a person whose personal information is not registered appear on the camera at the same time, processing and sending the video can obtain the information of the person whose personal information is not registered. As a result, the camera cannot function as a surveillance camera, and convenience is greatly reduced. On the other hand, if the image is transmitted without processing, the privacy of the person whose personal information is registered cannot be protected.

  Further, in the technique described in Patent Literature 2, when a plurality of persons are reflected on a camera, privacy of a person other than the target person is protected by using position information of the registered persons. Therefore, there is a problem that information of the person to be monitored needs to be registered in the system in advance. Surveillance camera systems are individually installed by governments, shopping malls, shopping centers, and the like, and cooperation between the systems is not sufficient. Therefore, in order to closely monitor the person to be monitored, it is necessary to register information on the person to be monitored in each monitoring camera system. However, registering personal information in a plurality of systems is cumbersome and therefore less convenient, and also increases security risks such as information leakage.

  Further, in the technology described in Patent Literature 3, by performing personal authentication of a registered person, privacy of a person other than the target person is protected when a plurality of persons appear in a camera. Therefore, similarly to the technique described in Patent Literature 2, it is necessary to register the information of the person to be monitored in the system in advance, and use in a plurality of monitoring systems is not sufficiently assumed, and convenience is increased. Not enough.

  Each of the technologies described in Patent Documents 2 and 3 above assumes that there are a plurality of persons to be monitored, but does not assume that there are a plurality of persons to be monitored. That is also an issue. For example, in watching a child, besides the purpose of each child's guardian knowing where his or her child is and what the situation is, the teacher of the school may ask what kind of There is also a use to know if it is a situation. In addition, when watching children, there is also a purpose for administrative officials to watch local children. However, for example, if a school teacher knows the information of children in other schools in detail, it may be against privacy protection.

  Thus, the present inventor has come to create an embodiment of the present invention with the above circumstances in mind. The monitoring system according to the embodiment of the present invention can improve convenience while protecting privacy. Hereinafter, a configuration example for realizing the above effects in the first embodiment of the present invention will be described in detail.

<1-2. Configuration Example>
(Monitoring system)
FIG. 1 is an explanatory diagram illustrating a configuration example of a monitoring system 99 according to the first embodiment of the present invention.

It is an information processing system having.

  The monitoring target terminal 1 is an information processing device corresponding to a monitoring target that is sensed (collects information) by the sensor 2. The monitoring target terminal 1 and the monitoring target may correspond, for example, on a one-to-one basis. The monitoring target according to the present embodiment may be, for example, a person, and an example in which the monitoring target is a child will be described below. The monitoring target terminal 1 may be held by a monitoring target (child) corresponding to the monitoring target terminal 1. Note that the present invention is not limited to the above example, and the monitoring target may be an animal, a car, or the like, and the monitoring target terminal 1 is attached to the monitoring target corresponding to the monitoring target terminal 1 ( May be worn).

  In the example shown in FIG. 1, the monitoring target user U102, which is a monitoring target, corresponds to the monitoring target terminal 1A, and the monitoring target user U104, which is a monitoring target, and the monitoring target terminal 1B correspond one-to-one.

  Further, the monitoring target terminal 1 transmits, to the monitoring device 3, identification information for identifying the monitoring target corresponding to the monitoring target terminal 1, and distribution level definition information regarding the monitoring target. The distribution level definition information is information that defines, for each distribution destination, a distribution level such as what kind of information about the monitoring target corresponding to the monitoring target terminal 1 is to be distributed and at what frequency. The distribution level definition information will be described later with reference to FIG. A configuration example of the monitoring target terminal 1 will be described later with reference to FIG.

  Although FIG. 1 shows an example in which the monitoring target terminal 1 is connected to the monitoring device 3 via the communication network 5, the monitoring target terminal 1 and the monitoring device 3 may be directly connected.

  Also, in FIG. 1, a smartphone is shown as an example of the monitoring target terminal 1, but the monitoring target terminal 1 is not limited to a smartphone. For example, the monitoring target terminal 1 is an information processing device such as a PND (Portable / Personal Navigation Device), a mobile phone, a PHS (Personal Handyphone System), a portable music player, a portable video processing device, a portable game device, and the like. There may be. Further, the monitoring target terminal 1 may be an IC tag.

For example, the sensor 2 includes a camera that acquires image information, a microphone that acquires audio information, an IC tag reader that acquires information from an IC tag, a biosensor that acquires biometric information on a monitoring target, and the like. May be a device that senses the information of the user. The sensor 2 provides the monitoring device 3 with monitoring information based on sensing of the monitoring target. Hereinafter, an example in which the sensor 2 is a camera and the monitoring information is image information will be described.

  The monitoring device 3 is an information processing device that distributes distribution information based on the monitoring information acquired from the sensor 2. For example, the monitoring device 3 authenticates the monitoring target terminal 1 based on the monitoring information and the identification information received from the monitoring target terminal 1. For example, authentication is performed based on matching between identification information extracted from the monitoring information and identification information of the monitoring target corresponding to the monitoring target terminal 1.

  Further, it generates distribution information based on the monitoring information and the distribution level definition information received from the authenticated monitoring target terminal 1, and transmits (distributes) the distribution information to the distribution destination terminal 4 via the communication network 5. A configuration example of the monitoring device 3 will be described later with reference to FIG. An example of the distribution information will be described later with reference to FIG.

  The distribution destination terminal 4 is an information processing device that receives distribution information from the monitoring device 3. The distribution destination terminal 4 may display, accumulate, or statistically process the received distribution information. The distribution destination terminal 4 may be, for example, a tablet terminal, a PC (Personal Computer), a server, or the like.

  For example, in the example illustrated in FIG. 1, the distribution destination terminals 4A and 4B are tablet terminals owned by distribution destination users U202 and U204, respectively, who are guardians of the monitored users U102 and U104 (children). In the example illustrated in FIG. 1, the distribution destination terminal 4C is a PC installed in a school where the monitored user U102 (child) attends and used by a teacher of the school. In the example shown in FIG. 1, the distribution destination terminal 4D is a server for collecting statistical data for a purpose other than visual monitoring.

  The communication network 5 is a wired or wireless transmission path for information transmitted from a device or a system connected to the communication network 5. For example, the communication network 5 may include a public line network such as the Internet, a telephone line network, and a satellite communication network, various LANs (Local Area Networks) including Ethernet (registered trademark), a WAN (Wide Area Network), and the like. . The communication network 5 may include a dedicated line network such as an IP-VPN (Internet Protocol-Virtual Private Network).

  As described above, the monitoring system 99 according to the present embodiment can distribute to the distribution destination defined by the distribution level definition information at the distribution level defined by the distribution level definition information while protecting the privacy of the monitoring target. It is possible, and convenience can be improved. Hereinafter, the configurations of the monitoring target terminal 1-1 (1) and the monitoring device 3-1 (3) according to the present embodiment, which are included in the monitoring system 99 having such an effect, will be sequentially described in detail.

(Monitoring target terminal)
A configuration example of the monitoring target terminal 1 (1A, 1B) illustrated in FIG. 1 will be described with reference to a configuration example of the monitoring target terminal 1-1 according to the present embodiment. FIG. 2 is a block diagram illustrating a configuration example of the monitoring target terminal 1-1 according to the present embodiment. As illustrated in FIG. 2, the monitoring target terminal 1-1 is an information processing device including a storage unit 111, a communication control unit 112, and a communication unit 113.

  The storage unit 111 stores programs and data used for the operation of the monitoring target terminal 1-1. Further, as shown in FIG. 2, the storage unit 111 stores an identification DB 111A and a distribution level definition DB 111B.

  The identification DB 111A stores identification information for identifying a monitoring target. The identification information may be, for example, a face image, a feature amount extracted from the face image, an image gait feature extracted from the image information, or the like. The identification information may be information corresponding to information obtained from the sensor 2. For example, when the sensor 2 is a biometric sensor, the identification information may be biometric information, and when the sensor 2 is an IC tag reader, May be the identification ID of the IC tag.

  The distribution level definition DB 111B stores distribution level definition information related to the monitoring target corresponding to the monitoring target terminal 1-1. FIG. 3 is an explanatory diagram illustrating an example of the distribution level definition information.

  The distribution level definition information T11 illustrated in FIG. 3 indicates, for example, distribution level definition information regarding the monitored user U102 stored in the distribution level definition DB 111B stored in the storage unit 111 of the monitoring target terminal 1A illustrated in FIG. It is a table. Further, the distribution level definition information T12 shown in FIG. 3 is, for example, the distribution level definition information regarding the monitored user U104 stored in the distribution level definition DB 111B stored in the storage unit 111 of the monitored terminal 1B shown in FIG. FIG.

  As shown in FIG. 3, the distribution level definition information associates information relating to a distribution destination (information of a distribution destination user or a distribution destination terminal) with a distribution level (delivery content, distribution frequency, etc.) (defines a relationship). It is. The distribution content may be, for example, one of image information, attribute information, and non-specific information, or a combination thereof. When the distribution content includes image information, for example, of the image information included in the monitoring information, an area related to the monitoring target may be distributed to a distribution destination associated with the distribution level definition information. When attribute information is included in the distribution content, for example, attribute information (for example, age, gender, etc.) extracted from image information (monitoring information) is distributed to a distribution destination associated with distribution level definition information. Good. Further, when non-specific information is included in the distribution content, information (non-specific information) for which the monitoring target cannot be specified may be distributed to the distribution destination associated with the distribution level definition information. For example, when non-specific information is included in the distribution content, any of mosaic processing, mask processing, and resolution reduction processing is performed on the area related to the monitoring target in the image information (monitoring information), and the distribution is performed. It may be delivered first. An example of the distribution information distributed to the distribution destination will be described later with reference to FIG.

  Further, in FIG. 3, the codes of the distribution destination user and the distribution destination terminal illustrated in FIG. 1 are shown as the information of the distribution destination user and the distribution destination terminal, but the present invention is not limited to the example. For example, the information of the distribution destination user and the distribution destination terminal included in the distribution level definition information may be, for example, a user ID and information for identifying the distribution destination terminal, respectively. In addition, in FIG. 3, “other” means all the distribution destination users other than the distribution destination users included in each table, or all the distribution destination terminals 4 other than the distribution destination terminals 4 included in each table.

  For example, in the distribution level definition information T11 shown in FIG. 3, the image information and the attribute information relating to the monitoring target user U102 are always distributed to the distribution destination terminal 4A owned by the distribution destination user U202 who is the guardian of the monitoring target user U102. Is done. Also, in the distribution level definition information T11, the distribution destination terminal 4C held by the distribution destination user U302 who is the teacher of the school of the monitoring target user U102 stores the image information and the attribute information on the monitoring target user U102 once a minute. It will be delivered. In the distribution level definition information T11, non-specific information that cannot identify the monitoring target user U102 is constantly distributed to the other distribution destination terminals 4.

  The communication control unit 112 illustrated in FIG. 2 controls the communication unit 113 to receive information from the monitoring device 3-1 and to transmit information to the monitoring device 3-1. For example, when the communication unit 113 receives the identification information request from the monitoring device 3-1, the communication control unit 112 may control the communication unit 113 to cause the monitoring device 3-1 to transmit the identification information. When the communication unit 113 receives the distribution level definition information request from the monitoring device 3-1, the communication control unit 112 controls the communication unit 113 to transmit the distribution level definition information to the monitoring device 3-1. Is also good.

  The communication unit 113 is a communication interface that mediates communication between the monitoring target terminal 1-1 and another device. The communication unit 113 supports an arbitrary wireless communication protocol or a wired communication protocol, and establishes a communication connection with another device via the communication network 5 described with reference to FIG. 1 or directly. The communication unit 113 transmits and receives information according to the control of the communication control unit 112.

  The acquisition unit 311 acquires, from the sensor 2, monitoring information based on sensing of a monitoring target. Note that, as described above, in the present embodiment, the sensor 2 is a camera, and the monitoring information is image information.

  The attribute information extracting unit 312 extracts attribute information to be monitored based on the monitoring information. The attribute information extraction unit 312 may detect, for example, the position of a person (monitoring target) in the image from the monitoring information, and may further extract information such as the age and gender of the monitoring target. For example, the attribute information extraction unit 312 may detect the position of a feature point such as an eye, a nose, and a mouth of a detected person's face, and estimate and acquire attribute information such as the age and gender of the person from the face. Good.

  The attribute information extracted by the attribute information extraction unit 312 is associated with a monitoring target from which identification information is extracted by an identification information extraction unit 313, which will be described later, based on information such as the position of the monitoring target. Provided to unit 315.

  The identification information extraction unit 313 extracts identification information for identifying a monitoring target based on the monitoring information. The identification information extracted by the identification information extraction unit 313 may be, for example, the same information as the identification information transmitted from the monitoring target terminal 1-1 to the monitoring device 3-1. For example, the identification information extracted by the identification information extraction unit 313 includes a face image, a feature amount extracted from the face image, an image gait feature extracted from the image information, biometric information, an identification ID of an IC tag, and the like. Is also good.

  The identification information extraction unit 313 may specify the position of the monitoring target in the image information (monitoring information), and associates the monitoring target position with the identification information and sends the identification information to the attribute information extraction unit 312 and the authentication unit 314. May be provided.

  The authentication unit 314 authenticates the monitoring target terminal 1-1 based on the monitoring information and the identification information of the monitoring target received from the monitoring target terminal 1-1 corresponding to the monitoring target. For example, the authentication unit 314 performs matching between the identification information of the monitoring target terminal 1-1 and the identification information extracted by the identification information extraction unit 313, and the monitoring target (image information) includes the monitoring target (image information). It is also possible to determine whether or not it is reflected. The authentication unit 314 may authenticate the monitoring target terminal 1-1 when the monitoring information includes the monitoring target.

  The matching of the identification information by the authentication unit 314 can be performed by various methods according to the identification information. For example, when the identification information is a face image, a feature amount extracted from the face image, or the like, the authentication unit 314 performs matching of the identification information using a face recognition technology as described in Non-Patent Document 1 below. May be performed. Further, when the identification information is an image gait feature, the authentication unit 314 may perform matching of the identification information using a gait authentication technology as described in Non-Patent Document 2 below.

  The matching of the identification information by the authentication unit 314 is not limited to such an example. For example, when the identification information is biometric information, the matching of the biometric information may be performed by the authentication unit 314. Hereinafter, an example will be described in which the identification information is a face image, and the authentication unit 314 performs matching based on the face image.

  The distribution information generation unit 315 performs distribution information generation based on the monitoring information and the distribution level definition information regarding the monitoring target corresponding to the monitoring target terminal received from the monitoring target terminal 1-1 authenticated by the authentication unit 314. Generate For example, the distribution information generation unit 315 processes the monitoring information based on the distribution level definition information described with reference to FIG. Generates distribution information to be distributed to.

  When there are a plurality of monitoring target terminals 1-1 authenticated by the authentication unit 314, the distribution information generation unit 315 determines based on the distribution level definition information of the plurality of authenticated monitoring target terminals 1-1. Distribution information may be generated.

  When the distribution content in the distribution level definition information on the monitoring target includes image information, the distribution information generating unit 315 generates distribution information including an area corresponding to the monitoring target in the image information included in the monitoring information. You may.

  When the image content is included in the distribution content in the distribution level definition information regarding the monitoring target, the distribution information generating unit 315 may generate distribution information including the attribute information of the monitoring target.

  If the distribution content in the distribution level definition information relating to the monitoring target is non-specific information, the distribution information generation unit 315 can specify the monitoring target in an area corresponding to the monitoring target in the image information included in the monitoring information. The distribution information may be generated by performing a process for eliminating it. The processing performed by the distribution information generation unit 315 to prevent the monitoring target from being specified may be, for example, a mosaic processing, a mask processing, a resolution reduction processing, or the like.

  An example of the distribution information generated by the distribution information generation unit 315 will be described later with reference to FIG.

  The communication control unit 316 controls the communication unit 317 to cause the communication unit 317 to transmit and receive information to and from another device. For example, the communication control unit 316 controls the communication unit 317 to transmit an identification information request for requesting identification information and a distribution level definition information request for requesting distribution level definition information to the monitoring target terminal 1-1. Is also good. Further, the communication control unit 316 controls the communication unit 317 to transmit (distribute) the distribution information generated by the distribution information generation unit 315 to the distribution destination terminal 4. Note that the communication control unit 316 may control transmission of distribution information based on, for example, information for identifying a distribution destination terminal included in the distribution level definition information.

  The communication unit 317 is a communication interface that mediates communication between the monitoring device 3-1 and another device. The communication unit 317 supports an arbitrary wireless communication protocol or a wired communication protocol, and establishes a communication connection with another device via the communication network 5 described with reference to FIG. 1 or directly.
