Description

  The present invention continuously carries out the work of converting information into a storable format without human intervention, and accumulates all of the converted information generated in large quantities in a form that can be referred to, that is, automatically records personal behavior records. The present invention relates to a personal behavior record storage method, a personal behavior record storage system, a program for realizing the system, and a computer-readable recording medium storing the program.

  Conventionally, personal information such as personal activities is generally recorded and stored in the form of diary, household account book, commemorative photo album, cassette tape recording at contract negotiation, etc. The utility is widely recognized.

  In the above conventional storage method, means such as photography and recording are used to convert information relating to personal activities into a format that can be stored. In addition, it is also possible to collect and store information after conversion by photography or recording in a place such as a photo album or cassette tape library in a form that can be referred to later. It had been.

  On the other hand, the capacity per unit price of storage devices connected to computers has increased in recent years, and the work of converting information into a format that can store information is carried out continuously and automatically without human intervention. It has become feasible to store all information in a form that can be referred to at a later date, that is, to store an individual's action history.

  However, no method has been proposed for automatically performing the control for accumulating the personal behavior history, and since no such device exists, it is not possible to automatically accumulate the personal behavior history. could not.

  Conventionally, a method has been proposed in which a person wears a video camera on his head and carries a recording device to photograph the surrounding situation. As an example of this method, there is Sawa 畠, Aizawa “Wearable Imaging System that Performs Event Detection from Sensor Information” (Technical Report of IEICE Technical Report IN2002-130, November 2002) (Non-patent Document 1). Using this method, it can be assumed that an individual's behavior history is captured and stored using a video camera.

  However, in the above prior art, in order to always accumulate an individual's action history, an individual must always carry a video camera or a recording device. These devices are heavy and are obstructive in shape, and complex devices need to be charged frequently because they are driven by batteries, making it difficult for individuals to always carry these devices. .

  Furthermore, there is a problem that the video that can be photographed by the above-described prior art is only the video called the first person view, in which the other party is seen from himself. In ordinary movies and TV dramas, it is composed of images called third-person viewpoints, where the main character and the other party appear in the composition in a normal scene. A third person perspective is suitable for recording what actions were taken on the spot. However, as long as an individual uses a conventional technology with a video camera attached, such an image cannot be taken.

  2. Description of the Related Art Conventionally, surveillance cameras have been put into practical use as devices that capture individual actions from a third person viewpoint. Surveillance cameras are installed at residential entrances, in stores, or in downtown areas by police to take pictures of the situation and store them on videotape for a certain period. The stored videotape will be disclosed to the investigating agency only when privacy is considered and there are requirements such as crimes. Also, if no crime occurs for a certain period of time, the stored contents are erased.

  When the above-mentioned surveillance camera is regarded as a conventional technique for recording individual behavior, there is a problem that the recorded contents can only be used by a third-party investigation organization and cannot be used by a photographed individual. It was.

  Even if the individual being photographed intends to view the video or keep a copy, the stored videotape will capture and record the entire sequence of situations at that location, so the individual will be there. It can be assumed that another person was filmed during the absence of time. For this reason, it is unacceptable to disclose videotapes because of the need for consideration of personal privacy.

  In addition, it is necessary for an editor who is a general person who is not an investigative agency to visually check the video tape, so that the editor visually confirms only the part where the individual is photographed, edits and copies it, and provides it to the individual. Due to the need for consideration of privacy, it is unacceptable due to social conventions. Therefore, from the standpoint of the individual photographed, the surveillance camera could not be used to accumulate the personal action history.

  2. Description of the Related Art Conventionally, there has been proposed a technique for recognizing and identifying a photographed person by analyzing a moving image photographed by a video camera using a computer. As an example of this method, “a surveillance camera for recognizing a face has been introduced secretly” (ASCII 24, August 8, 2002, http://ascii24.com/news/inside/2002/08/08) /637794-000.html) (Non-Patent Document 2), a monitoring camera and a face recognition monitoring system installed at a customs inspection table at Kansai International Airport.

  However, when using the above-mentioned conventional technology to identify an individual photographed with an installed camera and edit and copy only the part where the individual is photographed without human intervention, There was a problem that the recognition accuracy was not sufficiently high. In addition, a high-level calculation procedure associated with image processing is necessary for the recognition of a person, and there has been a problem that sufficient processing performance cannot be achieved with an inexpensive computer built-in type.

  2. Description of the Related Art Conventionally, an information providing technique has been proposed in which an individual's whereabouts are detected using a position recognition device such as a wireless ID tag and information such as advertisements corresponding to the individual's location is displayed on a TV screen near the individual's whereabouts. Yes.

  As an example of this technology, Tanabe and Kihara “Information Navigation Based on Real Space Metadata Collection” IPSJ “Multimedia, Distributed, Collaboration and Mobile (DICOMO2003) Symposium” pages 273-276, June 2003) (Non-Patent Document 3). In this technique, all advertisement information to be displayed is stored in advance in a centralized storage device, and an advertisement suitable for an individual is selected from the stored information and read out and displayed on a screen.

  However, the above prior art is a technique for providing information, and there is a problem that information cannot be stored and stored.

  Furthermore, if the apparatus of the above prior art simply reverses the information flow of the prior art, that is, replaces the TV screen of the prior art with a TV camera and reads the advertisement information from the storage device to the action history to the storage device Even if it is assumed that the device replaced with the storage of the device has been realized, this device cannot achieve the protection of privacy and cannot be put to practical use. That is, a series of contents storing all personal behavior histories is information that requires a high degree of privacy protection, and needs to be protected so that it cannot be unfairly viewed by others.

  However, in the device assumed above, since the personal action history is stored in a centralized storage device in common, all individuals, the operator of the device, those who attempt unauthorized access to the device, or unfair There is a possibility that the contents will be viewed by national institutions.

  For surveillance cameras that have been implemented and installed in the past, video tapes are discarded after a certain period of time, and the risk of such unauthorized browsing is reduced to an acceptable level, which is accepted by society. Has achieved a degree of privacy protection.

  Compared to this, in the device assumed above, since the personal action history is stored in a centralized storage device in common for all, it is not possible to achieve privacy protection that is accepted by social conventions. Such a device is unacceptable and cannot be put into practical use.

  In other words, using the conventional information providing technology or a technology that can be easily estimated from the conventional technology, it has not been possible to realize the accumulation of action history in a form that can be put to practical use.

  Conventionally, as a real-time video transmission system, there has been JP-A-2003-061083 (Patent Document 1). In this technique, it is possible to provide shooting target position detection means and a plurality of shooting cameras, and to switch the images of the plurality of cameras according to the position of the shooting target and deliver them in real time. However, in the above-described conventional technology, only real-time distribution is possible, and it is not possible to accumulate action histories including video.

  Conventionally, there has been JP-A-2003-125382 (Patent Document 2) as a storage-type video transmission system. In this technique, a shooting target position detection unit, a plurality of shooting cameras, a video recording unit, and a transmission video search unit are provided, all the videos of the plurality of cameras are accumulated, and a suitable video is selectively selected according to the position of the shooting target. It is possible to take out and make a call. As a possible application example of the technique, childcare monitoring in a kindergarten is cited in the literature.

  However, in the above prior art, since the personal action history is stored in a centralized storage device in common, all individuals, the operator of the device, those who attempt unauthorized access to the device, unfair national organizations, etc. May be viewed.

  As described above, the technology in which all of the individual behavior histories are accumulated in a centralized storage device cannot achieve privacy protection that is accepted by social conventions. It cannot be put to practical use.

  The above-mentioned prior art can only be applied to applications that require very little consideration for privacy protection, such as childcare monitoring in kindergarten, and can be used to accumulate behavior history for general adults. could not.

  Conventionally, GPS has been put to practical use as a technique for acquiring the current position, and the current position can be obtained as point coordinates in the form of latitude and longitude outdoors.

  However, when the conventional technique is used to identify an individual photographed by an installed camera, there is a problem that it cannot be used indoors where the main camera is installed.

  Conventionally, a wireless ID tag has been put into practical use as a technique for acquiring the current position used indoors, and the base station installation location is in the form of whether or not the base station is installed indoors at a fixed point. The current position can be obtained as the point coordinates.

  For example, information that detects the individual's whereabouts using the position recognition device such as the wireless ID tag described above as the prior art and displays information such as advertisements according to the individual's location on the TV screen in the vicinity of the individual's whereabouts In the provided technology, the wireless ID tag is used.

  However, when using the conventional wireless ID tag to identify an individual photographed by an installed camera, which camera was photographed from the current position information obtained by the conventional technique. There is a problem that it is not directly known whether the video should be accumulated. In the information providing technology, a TV screen is also installed at the base station installation location of the wireless ID tag, and control is performed by directly associating the detection signal of the wireless ID tag at the base station with the information display on the TV screen.

  On the other hand, when targeting the purpose of accumulating personal video shot with a camera, generally the shooting range included in the shot image of the camera has a certain extent, and when multiple cameras are installed, These shooting ranges can overlap each other.

  Also, for example, in general, when recording sound with a microphone accompanying an image, the sound collection range of the microphone has a certain extent, and when a plurality of microphones are installed, those sound collection ranges are Can overlap each other.

  For this reason, in order to determine which of a large number of information source devices such as cameras and microphones should be driven for photographing, it is directly determined from point coordinates obtained by conventional position acquisition techniques such as GPS and wireless ID tags. There was a problem that could not be determined.

  Furthermore, when the wireless ID tag of the above prior art is used and a wireless ID tag is installed at the entrance of the room and a camera is installed in the room to shoot and store an individual video in the room, While in the room, there is a problem in that information on the current position that is an opportunity for driving the camera cannot be obtained from the wireless ID tag base station.

  In other words, since the base station can receive radio waves from the wireless ID tag in a narrow range of several tens of centimeters to several meters, when the base station is installed at the entrance of the room, it detects the radio waves from the wireless ID tag in the room. Can not.

  For this reason, when using a wireless ID tag, which is a position acquisition technology, to identify an individual photographed with an installed camera, the wireless ID tag is used when photographing should be performed, that is, when the individual is in a room. There was a problem that radio waves could not be received, information about the current position could not be obtained from the wireless ID tag, and therefore it was not possible to determine which camera should be driven.

JP 2003-061083 A JP 2003-125382 A Sawa 畠, Aizawa “Wearable imaging system that detects events from sensor information” (IEICE Technical Report IN2002-130, November 2002) "The surveillance camera that recognizes the face was introduced secretly by Kanku" (ASCII 24, August 8, 2002, http://ascii24.com/news/inside/2002/08/08/637794-000.html) Tanabe, Kihara “Information Navigation Based on Real Space Metadata Collection” IPSJ “Multimedia, Distributed, Collaboration and Mobile (DICOMO2003) Symposium” pages 273-276, June 2003)

  As described above, conventionally, the work of converting information into a format in which information can be stored is continuously performed without human intervention, and a large amount of converted information is accumulated in a form that can be referred to, that is, an individual's action history is stored. There was a problem that it could not be automatically accumulated.

  In addition, in a method in which an individual wears a video camera on his head and carries a recording device to capture the surrounding situation, it is difficult for the individual to always carry a video camera or recording device, and There was a problem that only the first-person view from which the other person is seen can be taken.

  Also, with surveillance cameras that are devices that capture personal actions from a third-person perspective, the recorded content can only be used by third-party investigation agencies and cannot be used to accumulate personal action histories. was there.

  In addition, the technology for recognizing and identifying a person captured by analyzing a moving image shot with a video camera with a computer requires a problem that the recognition accuracy of the person is not sufficiently high and an advanced calculation procedure associated with image processing. There was a problem that sufficient processing performance could not be achieved with an inexpensive computer with built-in equipment.

  Further, in an information providing technique of detecting an individual's whereabouts using a position recognition device such as a wireless ID tag and displaying information such as advertisements according to the individual's location on a TV screen in the vicinity of the individual's whereabouts, There was a problem that accumulation of action history could not be realized in a form that can be provided.

  Further, the real-time video transmission system has a problem that only real-time distribution is possible and action history cannot be accumulated.

  In addition, the storage-type video transmission system has a problem that it cannot be used for storing action histories of general adults and the like that are highly required for privacy protection.

  In addition, GPS, which is a technology for acquiring the current position, has a problem that it cannot be used indoors, and in the current position acquisition technology such as GPS and a wireless ID tag, only point coordinates are obtained as the current position. There has been a problem that it is not possible to directly determine which of the information source devices such as a camera and a microphone should be driven for photographing.

  In addition, in the wireless ID tag that is a technique for acquiring the current position, while the individual to be photographed is in the room, information on the current position that is an opportunity for driving the camera in the room is the entrance of the room. There is a problem that it cannot be obtained from the wireless ID tag base station installed in the network.

  The object of the present invention is to solve these problems of the prior art and continuously perform the operation of converting the information into a format that can store the information without human intervention so that all the converted information generated in large quantities can be referred to.

The result is whether the corresponding logical position name is obtained or the logical position name cannot be obtained because there is no matching data. If a logical position name is obtained, it is information on a logical position range representing the current position of the user (step S2).

  FIG. 6 is a diagram showing data stored in the terrain database (21). Correspondences 211 to 215 between the terrain (logical position name) and sensors (basic position sensor (base station)) are held.

  For example, when the base station α (11) receives radio waves, sends information, and is received by the position specifying control function unit (26), the logical position name “lobby” is obtained as a result of searching the terrain database (21), This is a logical location representation of where the user is currently. That is, it is possible to calculate information that the user currently exists in a logical position range represented by the name “lobby”, which is a space range to be imaged by the information source device including the camera B (42).

  Here, the installation form of the camera B (42) is a subject to be photographed up to the entrance of the room (1), but is not a subject to be photographed in the room (1). Therefore, while the user is in the reception range α (14), the camera B (42) should be driven, and the contents of the terrain database (21) shown in FIG. 6 are set as such. .

  Further, for example, when the base station β (12) receives radio waves, sends information, and receives the position specifying control function unit (26), there is no matching data as a result of the search of the terrain database (21). The logical location name is not obtained and the logical location where the user currently exists is unknown.

  Next, the position specifying control function unit (26) searches the inference rule database (22) to obtain an inference result. Information stored in the previous user position holding unit (27) is used as a key for this search (step S3).

  FIG. 7 is a diagram showing a data structure held by the user previous position holding unit (27), which includes a user name 271, a previous reception sensor 272, a previous logical position 273, and a previous position update time 274. This is equivalent to the number of users.

  The position specifying control function unit (26) searches for an entry that matches the user name (271) from the information stored in the user previous position holding unit (27), and records the previous reception sensor (272) recorded therein. ) And the information of the previous logical position (273) and the information on which base station received and received the information this time, that is, the information on the current sensor, the inference rule database (22) is searched.

FIG. 8 is a diagram showing data held in the inference rule database (22).
In FIG. 8, items with diagonal lines in the previous logical position column mean that the previous logical position item is not used for matching in the search.

  For example, it is assumed that the content recorded in the inference rule database (22) was recorded as α as the previous reception sensor and “room” as the previous logical position, and the position specifying control function unit (26) Assume that information from the station β (12) is received. The position specifying control function unit (26) searches the inference rule database (22) to obtain an item that matches the previous sensor α and the current sensor β, and in this case, the inference is performed without using the item of the previous logical position for the match determination. As a result, “Lobby → (Unknown)” is obtained.

  The meaning of this result can be inferred that the user was present in the lobby (2) from the previous reaction of the base station α (11) to the current response of the base station β (12), and the base station β ( This means that after passing through 12), it is not known whether it exists in the toilet (3) or in the corridor (4).

  Based on the inference result, the position specifying control function unit (26) determines that the previous logical position information stored in the user previous position holding unit (27) is “indeterminate” and the inference result of this time When the logical position that has been used so far is found (step S4), the following processing is performed.

  First of all, the user name has been clarified in the procedure so far, and the logical position that has been so far is the item written on the left side of the arrow “→” of the inference result, and The time at which the presence is started is the previous position update time stored in the user previous position holding unit (27), and the time at which the existence at the logical position is completed is the current time. Based on these pieces of information, a logical position notification communication is transmitted to the accumulation instructing unit (30) (step S5).

FIG. 9 is a diagram showing the communication content A of the logical position notification, which includes a user name A1, a logical position name A2, a start time A3, and an end time A4.
The position specifying control function unit (26) further performs the following processing regarding the current logical position. First, it is confirmed whether or not the current position is specified as a result of the search of the terrain database (21) (step S6), and if it is not specified, the item written on the right side of the arrow “→” of the inference result Is the inference result regarding the current logical position, and this is adopted (step S7).

  When the current logical position is determined by these procedures (step S6 or step S8), a logical position notification communication is transmitted to the accumulation instructing unit (30) (step S12 or step S9). At that time, the user name and the logical position name are made clear by the above procedure, the start time is the current time, and the end time is “undecided”.

  Then, the information stored in the user previous position holding unit (27) is updated as follows (step S10). The item “previous logical position” is the current logical position. At this time, if the current logical position is unknown as a result of inference, “undecided” is recorded (step S11). The item of “previous position update time” is the current time. In addition, the item “previous reception sensor” is the base station received this time if the current position is not specified as a result of the search of the terrain database (21). Keep the contents.

  Thus, the logical position inference procedure in the current or past time interval of the user shown in FIG. 5 is completed.

  After that, if the current position is specified as a result of the search of the terrain database (21), the position specifying control function unit (26) waits until the user leaves the reception range of the base station, and Assuming that reception from the station has occurred, the above inference procedure is executed again. At this time, it is assumed that there is no matching data as a result of the search of the terrain database (21), and re-execution is started from the search of the inference rule database (22).

  The method of detecting that the user has left is an operation in which in the wireless ID tag system used in this embodiment, information is periodically sent to the network at intervals of about 7 seconds while the wireless ID tag is in the reception range. If the information from the base station is not received for 8 seconds or more, it can be determined that the user carrying the wireless ID tag has left the reception range.

The reason why the above inference procedure is executed again will be described below with a specific example of operation.
For example, assuming that the user enters the room (1) via the hallway (4) and the lobby (2), while the user is in the reception range α (14) of the base station α (11) The camera B (42) should be driven because it is the shooting range of the camera B (42), and it can be assumed that the user has entered the room (1) when the user is out of the reception range α (14). This is because the camera A (41) should be driven because it is within the shooting range of

  In this case, the first inference procedure corresponds to the case where the current position is specified as a result of the search of the terrain database (21), and when the user is out of the reception range α (14), it is This corresponds to the case where the above inference procedure is executed and the current position is not specified as a result of the search of the terrain database (21), and the result of the search of the inference rule database (22) is “lobby → room”. Therefore, “room” is obtained as an inference result regarding the current logical position, and camera B (42) and camera A (41) are sequentially driven appropriately as a result of the first inference procedure and the second inference procedure, respectively. Therefore, the above-described processing procedure means that the logical position notification communication is transmitted to the accumulation instructing unit (30).

  In addition, the processing procedure as a result of the camera being driven after transmission of the logical position notification communication to the accumulation instructing unit (30) will be described below.

  In the present embodiment, a wireless ID tag system is used as a basic sensor for acquiring position information. The scope of the present invention is not limited to this, but a GPS, an automatic railway ticket gate, an electronically controlled door opening / closing key, a position information system using a control signal such as a mobile phone or PHS, a biometric information matching sensor such as a fingerprint, a fixed Any technique that can detect the movement or presence of a specific object, such as the input of a password to an installation terminal, can be easily used as a basic sensor, and a combination of these multiple types of information sources can also be used.

  For example, when GPS is used, the lower items of the data held in the terrain database (21) are described in a form such as “within a rectangular area with the east longitude PP north latitude QQ and the east longitude XX north latitude YY as a diagonal line”. By doing so, it is possible to calculate as logical position information whether or not it currently exists in the specific position range.

  Moreover, in this Embodiment, the arrangement | positioning with which the imaging | photography range of a camera did not overlap was illustrated as an object building. The scope of the present invention is not limited to this, and the photographing ranges of the cameras may overlap. For example, a lecture stand is installed in the room (1), a camera C for photographing the lecture stand in detail and a copy control unit C for controlling the camera are installed, and a reception range for detecting that the user has approached the lecture stand. A base station δ having δ (delta) may be installed.

  In this case, “lecture stand in the room” is newly established as a logical position. It can be understood that the logical position has a relationship included in the logical position “room” exemplified in the present embodiment. Further, an item of logical position name “lecture stand in the room” → basic position sensor “base station δ” is added to the data held in the terrain database (21). Further, data held in a logical position camera correspondence table (32) described later includes logical position names “lecture stand in the room” → “camera name A, copy control unit A” and “camera name C, copy control unit C”. Is added.

  As a result of the above change, when the user approaches the lecture stand, the camera C can be used to capture the situation in more detail than the video of the camera A. As described above, the logical position is not limited to a fixed relationship in which the reception range of the sensor and the shooting range of the camera have a one-to-one correspondence, and the logical position includes an inclusion relationship according to the overlap of the shooting ranges of the camera. It has the flexibility that can be defined as appropriate. This embodiment can operate even in the above-described definition of the logical position by changing the data held.

FIG. 10 is a diagram illustrating a functional configuration of the accumulation instructing unit (30).
As shown in the figure, the accumulation instructing section (30) includes an operating system (38) and a storage instruction control function section (31), a logical position camera correspondence table (32) and a user storage area correspondence table (33). It has a communication device (39).

  The accumulation instructing unit (30) receives the logical position notification communication from the position specifying unit (20), and the accumulation instructing control function unit (31) performs the following processing.

  FIG. 11 is a diagram showing data held in the logical position camera correspondence table (32), which holds correspondence between logical position names and cameras. In the example shown in the figure, for example, the logical position name “room” corresponds to the camera A and the copy control unit A (321), and the logical position name “lobby” corresponds to the camera B and the copy control unit B. Show.

  The accumulation instruction control function unit (31) searches the logical position camera correspondence table (32) based on the logical position name included in the logical position notification communication, and obtains the corresponding camera name and copy control unit name.

  FIG. 12 is a diagram showing data held in the user storage area correspondence table (33), which includes a user name 331, a storage destination storage device 332, and a storage destination directory name 333, which are provided for the number of users.

  Next, the accumulation instruction control function unit (31) searches the user storage area correspondence table (33) based on the user name included in the communication of the logical position notification, and the corresponding storage destination storage device, that is, the storage device (70). And a character string indicating the name of the corresponding storage destination directory, that is, the user storage area (71). At this time, when “not applicable” is obtained, the processing of the accumulation instruction control function unit (31) is completed here. Otherwise, the accumulation instruction control function unit (31) then transmits a save start / end instruction communication to the corresponding copy control unit.

  In the above-described embodiment, the contents of the logical position camera correspondence table (32) include one set of camera names and copy control unit names or none corresponding to one logical position name. The scope of the invention is not limited to this, and a plurality of corresponding camera names and copy control unit names may be listed for one logical position name. The accumulation instruction control function unit (31) may transmit a storage start / end instruction communication to a plurality of corresponding copy control units listed.

  FIG. 13 is a diagram showing the communication content B of the save start / end instruction, and is composed of a user name B1, a storage destination storage device B2, a storage destination directory name B3, a start time B4, and an end time B5.

  The information obtained in the above procedure is used for the user name B1, the storage destination storage device B2, and the storage destination directory name B3. Information included in the communication content of the received logical position notification is used for the start time B4 and the end time B5. At this time, the end time may be described as “undecided”, but this value is used as it is for transmission.

  For example, when “room” is written as the logical position name in the communication content of the received logical position notification, as a result of searching the logical position camera correspondence table (32), the camera A (41) and the copy control unit A (61 ) Is obtained, and a save start / end instruction communication is transmitted to the copy control unit A (61).

  The copy control unit A (61) always acquires video information from the camera A (41) and records it in the temporary storage device A (51). Temporary storage device A (51) stores a certain amount of video, for example, 24 hours, and erases the storage area and reuses it for storing new video information as needed.

  The copy control unit A (61) receives a storage start / end instruction communication from the accumulation instruction control function unit (31), and performs the following processing. When the start time included in the communication content of the save start / end instruction is the current time, the copy control unit A (61) acquires the video information from the camera A (41), and stores the information as needed in the storage device ( 70).

  This accumulation process is continued thereafter, and continues until the next storage start / end instruction communication relating to the same user is received, at which point the accumulation process is terminated. Further, when the start time included in the communication content of the storage start / end instruction is not the current time, it means that the storage start / end instruction is an instruction to accumulate past information. The video information of the time interval from the start time to the end time is read from the temporary storage device A (51), and the information is stored in the storage device (70) according to the following procedure.

Accumulation of video information in the storage device (70) is performed in the following procedure.
Communicates with the storage destination storage device included in the communication content of the save start / end instruction, and stores the existing information in the storage area of the information indicated by the storage destination directory name included in the communication content of the save start / end instruction A new file name that does not overlap with the file name to be acquired is acquired.

  Next, for the storage destination storage device, the file indicated by the acquired new file name in the storage area of the information indicated by the storage destination directory name included in the communication content of the save start / end instruction is shown below. A data write command representing information, that is, video information and a command for writing information representing the specifications of the video information are transmitted through the network.

  FIG. 14 is a diagram showing the stored content C of the video in the storage device, and includes a start time C1, an end time C2, a shooting condition C3, and a content C4.

  In the figure, content C4 is a data string representing video information, and the start time C1 and the end time C2 use information included in the communication content of the storage start / end instruction. In the shooting condition C3, in addition to a character string that describes the installation location of the camera A (41), shooting information such as camera sensitivity is used and stored.

  The storage device in which information related to a certain user is stored and the storage destination directory name can be individually registered for each user in the user storage area correspondence table (33).

  For the target user in the above description, the storage area (71) for the user in the storage device (70) is used as the storage destination, but another storage device and the storage destination directory name are assigned to another user. It is done.

  As explained above, since a reliable storage device can be individually designated for each user as a storage location, there is a risk that the user's personal information will be stored in an unreliable storage device and exposed to a third party attack at a later date. Can be removed.

  As a representation format of video information used in the present embodiment, a widely used video format such as the MPEG standard can be used. In addition, as the storage device (70) used in the present embodiment, widely used software such as a UNIX (registered trademark) operating system having an NFS function and a Windows (registered trademark) operating system having a network folder function, and the like. Can be used, and communication with the storage device (70) is performed using a communication protocol provided by the software.

  Similarly, the camera B (42), the temporary storage device B (52), and the copy control unit B (62) are also used for the camera A (41), the temporary storage device A (51), and the copy control unit A (61). Perform the same processing procedure as.

  Further, the copy control unit A (61) and the copy control unit B (62) store the temporary storage device A (51) and the temporary storage device B (52) after a predetermined time has elapsed from the recording, for example, after 24 hours. Delete the contents. Since the necessary video information has already been copied to the user storage area (71), even if it is deleted, the operation of this system will not be hindered.

  The deletion process erases the personal action history accumulated in the centralized storage device, that is, the temporary storage device A (51) and the temporary storage device B (52) after a certain period of time. The possibility of content being viewed by an individual, an operator of the device, a person who attempts unauthorized access to the device, or an unfair national organization, etc. can be removed, and the risk of such unauthorized viewing can be removed, Achieving privacy protection that is acceptable to society. Therefore, the present embodiment can be put to practical use for the purpose of accumulating behavior histories of general adults and the like that need to be considered for privacy protection.
