JP 2007-104518 A (page 5-8, FIG. 1)

  In such a conventional image management system, a password (password information) is set when image data (managed information) is recorded, and a password is required to refer to the recorded image data later. . In this way, in the conventional system, only a person having an appropriate authority (such as an administrator) can refer to the image data, and a third party without an appropriate authority can illegally refer to the image data. Is prevented.

  However, in the conventional system, when the administrator when setting a password (past administrator) and the administrator when referring to image data (current administrator) are different, for example, the administrator is changed. In such a case, there is a problem that the current manager cannot refer to the image data in which the password is set unless the past manager is informed of the password. In such a case, the current administrator can record or refer to the current image data captured by the surveillance camera, but refers to the past image data recorded in the image recording device or the like. However, there is a problem that the convenience in handling the managed information in which the password information is set is low even though the person has appropriate authority.

  The information management device according to the present invention includes a managed information storage unit that stores the managed information received from the information output device, and password information that is set when the managed information is written. It is set when a password information storage unit that stores the password information that is requested to be input when information is read in association with the managed information and when the managed information is newly written. If the password information is different from the password information stored in the password information storage unit as the password information corresponding to the managed information already stored in the managed information storage unit, the password information is stored in the password information storage unit. A recording processing unit that rewrites the set password information to the newly set password information.

  According to this apparatus, when an authorized person (such as an administrator) sets password information (such as a new password) when newly writing managed information (such as current image data), The password information (old password or the like) stored in the password information storage unit is rewritten with the newly set password information (new password or the like). Accordingly, even if a person with appropriate authority does not know the password information (old password, etc.) stored in the password information storage unit, the password information can be regenerated by rewriting the password information. Settings can be made, and management information can be read out. Thereby, the convenience in handling the managed information in which the password information is set is improved.

The stored password information may be rewritten.

  Thereby, based on the identification information of an information output device, the password information associated with the identification information can be rewritten. For example, if new password information is set when information to be managed (current image data, etc.) received from an information output device with certain identification information is written, the past information received from the information output device with the same identification information is set. The password information of the management information (past image data, etc.) is rewritten with this new password information. In this way, by rewriting the password information collectively based on the identification information of the information output device, for example, even under a situation where different administrators or authorities are set for each information output device, the information The password information can be rewritten and newly set corresponding to the output device, and convenience in handling the managed information in which the password information is set is improved.

  The program of the present invention includes a managed information storage unit that stores managed information received from an information output device, and a password information storage that stores the password information requested to be input when the managed information is read. A program executed in an information management apparatus comprising: a process for storing the password information in association with the managed information when the managed information is written; Password information set when the managed information is written, and password information stored in the password information storage unit as password information corresponding to the managed information already stored in the managed information storage unit Is different from the above, the computer is caused to execute a process of rewriting the password information stored in the password information storage unit with the newly set password information.

  Even with this program, even if the person with appropriate authority does not know the password information (old password, etc.) stored in the managed information storage unit, the password information can be rewritten in the same way as the above-mentioned device. By doing so, it is possible to read the managed information in which the password information is set. Thereby, the convenience in handling the managed information in which the password information is set is improved.

  According to the present invention, it is possible to rewrite the password information stored in the password information storage unit using the password information that is set when new management information is written, and have appropriate authority. Convenience when a person handles managed information in which personal identification information is set.

FIG. 5 is a diagram illustrating an example of the image management table. As shown in FIG. 5, in one image management table, the identification information (image recording device 0001, etc.) of the image recording device 3 that is the transmission source of image data, the file number (No. 01, etc.) of the image data, Shooting time (June 15, 2008 15:35:00, etc.) and shooting end time (June 15, 2008 15:55:00, etc.), image data recording area 19 (data folder XXX1) Etc.) and a password for image data (such as 02468) are recorded for each image data. In the example of FIG. 5, three image management tables are created for each image recording apparatus 3 (for each monitoring area).

  The control unit 21 includes a microcomputer including a CPU, a ROM, a RAM, and the like and peripheral circuits thereof. The control unit 21 includes a communication control unit 22, a recording processing unit 23, an authority determination unit 24, a display control unit 25, and the like as functional modules realized by a computer program executed on the microcomputer. ing.

  The communication control unit 22 has a function of controlling communication with the image recording apparatus 3. When receiving image data from the image recording device 3, the communication control unit 22 establishes communication with the image recording device 3 using a protocol such as HTTP, and when reception of the image data ends, Control to end communication with the image recording apparatus 3 is performed.

  In addition, when an image data reception request is input from the operation unit 18, the communication control unit 22 transmits an image request signal to the corresponding image recording device 3, and communicates with the image recording device 3. Communication is established and image data transmitted from the image recording apparatus 3 is received in response. The image data received from the image recording device 3 is displayed and output on the display unit 17. When a recording request is input from the operation unit 18, the received image data is recorded in the image recording unit 19. Then, when the reception of the image data is completed, or when an image reception stop request is input from the operation unit 18, the communication control unit 22 transmits a communication end request signal to the corresponding image recording apparatus 3. Then, the communication with the image recording apparatus 3 is terminated.

  When an image recording request is input from the operation unit 18, the recording processing unit 23 performs processing for recording image data received from the image recording device 3 in the image recording unit 19. At this time, the recording processing unit 23 associates the file information (file number, recording area, etc.) of the image data, the identification information of the image recording apparatus 3 that is the transmission source, the shooting time and the shooting end time, and the password, and Is stored in the image management table.

  This recording processing unit 23 is already stored in the image management table of the storage unit 20 and the password information (new password) input and set by the administrator from the operation unit 18 when image data is newly recorded. When the password information (old password) is different, the password information (old password) in the image management table is rewritten to the newly set password information (new password). The password information (password) is rewritten for each image recording apparatus 3 (for each monitoring area).

  Specifically, when receiving the image data to be recorded from the image recording device 3, the recording processing unit 23 first determines whether or not the identification information of the image recording device 3 is recorded in the image management table. If the identification information is recorded in the image management table, the password information (old password) relating to the image data recorded for the image recording apparatus 3 having the same identification information, and the password information newly input from the operation unit 18. Compare (new password). If the password information (old password) regarding the recorded image data is different from the password information (new password) input from the operation unit 18 for the image recording apparatuses 3 having the same identification information, the recording processing unit 23 The password information (old password) related to the image data already recorded for the image recording apparatus 3 having the same identification information is rewritten with the newly input password information (new password). That is, the password information (old password) when the previous image data was recorded is updated with the password information (new password) when the image data was last recorded, and each image recording apparatus 3 that is the transmission source of the image data In addition, the image data and the password information are managed so that the same password information (password) is set.

  FIG. 6 is a diagram showing an example of management of such image data and password information. In FIG. 6, when the current image data (No. 07 image data) received from the image recording apparatus 3 with the identification number “0001” is recorded, a new password “13579” different from the old password “02468” is recorded. A set example is shown. In such a case, as shown in FIG. 6, the password of the image data (No. 01 to 06) recorded before that time is rewritten with the new password “13579”.

  When the image data display request is input from the operation unit 18, the authority determination unit 24 determines whether or not the administrator has authority to refer to the image data based on the password input by the administrator. Check. For example, the authority determining unit 24 determines whether or not the input password matches the password stored in the image management table corresponding to the designated image data, and displays the determination result (OK or NG). To the unit 25.

  The display control unit 25 performs control to display and output the image data on the display unit 17. For example, when receiving image data from the image recording device 3, the display control unit 25 sequentially performs decompression processing on the received image data and outputs the display data to the display unit 17. In this case, a plurality of images may be displayed simultaneously by dividing the display screen into a plurality of parts (see FIG. 4).

  Further, when the display control unit 25 receives an input of a display request for image data recorded in the image recording unit 19 from the operation unit 18, if the determination result of the authority determination unit 24 is OK (authorized), the image is displayed. The corresponding image data is extracted from the recording unit 19, subjected to expansion processing, and displayed on the display unit 17. In addition, when the display control unit 25 receives an input of a display request for image data recorded in the image recording unit 19 from the operation unit 18, if the determination result of the authority determination unit 24 is NG (no authority), the display control unit 25 An alert (NG display) indicating that is displayed on the display unit 17.

  The operation of the image management apparatus 4 configured as described above will be described with reference to the flowcharts of FIGS.

As shown in FIG. 7, when the image management apparatus 4 is activated, it is determined whether an image data reception request has been input from the administrator (S1). When a request for receiving image data is made, processing for receiving and displaying image data from the corresponding image recording device 3 is performed (S2). The image data received from the image recording device 3 is sequentially expanded and displayed on the display unit 17.

  Subsequently, it is determined whether or not an image data recording request is input from the administrator (S3). When an image data recording request is made, processing for recording the corresponding image data is performed (S4). In this image data recording process, password setting and rewriting are performed. These processes will be described later with reference to FIG.

  Next, it is determined whether or not an image data reproduction request is input from the administrator (S5). When a reproduction request for image data is made, a process for reproducing the corresponding image data is performed (S6). In this image data reproduction process, processes such as password input and matching determination are performed. These processes will be described later with reference to FIG.

  Then, it is determined whether or not the administrator has performed an end operation using the operation unit 18 (S7). When the end operation is performed, the image management apparatus 4 performs an end (for example, shutdown) operation.

  Next, the image data recording process will be described in detail with reference to FIG. As shown in FIG. 8, in the image data recording process, first, it is determined whether or not the image recording apparatus 3 that is the transmission source of the image data has been designated and a password for the image data has been input (S10).

  When both the designation of the image recording device 3 as the transmission source and the input of the password are performed, whether the image data of the same image recording device 3 is recorded based on the identification information of the image recording device 3 and the image management table It is determined whether or not (S11). If the image data of the same image recording device 3 has not been recorded before, that is, if the first image data of the image recording device 3 is recorded, a new image management table of the image data is created ( S12).

  On the other hand, if the image data of the same image recording device 3 has been recorded before, the input password (new password) is the same as the recorded password (old password) of the same image recording device 3. Is determined (S13). If the new password is different from the old password, the password is rewritten (image management table is updated) (S14). For example, as shown in FIG. 6, when a new password different from the old password “02468” is set, the passwords of all the image data of the image recording apparatus 3 are collectively rewritten to the new password “13579”. It is done.

  Next, it is determined whether the image data to be recorded is the image data being displayed (current image data) (S15). If the image data to be recorded is not current image data, that is, past image data, a request to receive the past image data (designation of shooting time, etc.) is made (S16), and the received image Data recording is performed (S17). On the other hand, when the image data to be recorded is the current image data, the currently received image data is recorded (S17).

  Then, it is determined whether or not the administrator has performed a recording end operation (S18), and when the recording end operation has been performed, the image data recording process ends.

  Next, image data reproduction processing will be described in detail with reference to FIG. As shown in FIG. 9, in the image data reproduction process, first, it is determined whether or not the image data to be reproduced is designated and the password of the image data is input (S20).

  When both the designation of image data and the input of a password are performed, it is determined whether or not the image data to be reproduced is recorded with reference to the image management table (S21). If it is determined that the image data to be reproduced is recorded, it is determined whether or not the input password matches the recorded password (S22). If the passwords match, the image data is reproduced (S23). On the other hand, if the image data to be played back is not recorded, or if the passwords do not match, an NG display is displayed on the display unit 17 (S24).

  Then, it is determined whether or not the administrator has performed a reproduction end operation (S25), and when the reproduction end operation has been performed, the image data reproduction process ends.

  According to the image management apparatus 4 of the present embodiment as described above, the image management table stored in the storage unit 20 using the password information (new password) set when image data is newly recorded. The password information (old password) can be rewritten, and convenience when an authorized person (administrator) handles image data set with the password information (old password) is improved.

  In other words, in the present embodiment, when a person (administrator) having appropriate authority sets password information (new password) when newly recording image data, the image stored in the storage unit 20 is stored. The password information (old password) in the management table is rewritten with the newly set password information (new password). Therefore, even if the administrator does not know the past password information (old password) stored in the image management table, the password information is rewritten by rewriting the password information (password) as described above. Settings can be made and past image data can be referred to. Thereby, convenience in handling image data in which personal identification information is set is improved.

  Further, in the present embodiment, based on the identification information of the image recording device 3, the personal identification information associated with the identification information can be rewritten. For example, when new password information “13579” is set when the current image data received from the image recording device 3 with a certain identification number “0001” is recorded, the image recording device 3 with the same identification number “0001” is set. The password information “02468” of the past image data received from is rewritten with the new password information “13579”. As described above, based on the identification information of the image recording device 3, it becomes possible to rewrite the password information for each image recording device 3 (for each monitoring area). Even if the authority to receive or refer to is different, this can be dealt with, and convenience in handling image data in which personal identification information is set is improved.

  For example, when the manager is changed, the new manager may not be informed of the old password of past image data. Even in such a case, the new administrator can rewrite (reset) the password of the past image data by recording the current image data with the new password. As a result, a new administrator can refer to (reproduce) past image data. Or, when an organization such as the police asks you to submit past image data, even if passwords for many image data have been set separately, rewrite these image data passwords in a batch (reset) By doing so, it is possible to read and output past image data.

  That is, in this case, the identification information and password of the image recording device 3 are recorded in association with the image data, and the password set in the recorded image data received from the same image recording device 3 in the past is It can be overwritten and updated with a password for newly recorded image data. Thereby, although the administrator has an appropriate authority (for example, although it is possible to access the remote image recording apparatus 3 via the network and refer to the image), in the past, Since the password at the time of recording is unknown, it is possible to prevent the image data from being referred to.

  The embodiments of the present invention have been described above by way of example, but the scope of the present invention is not limited to these embodiments, and can be changed or modified in accordance with the purpose within the scope of the claims. is there.

  For example, in the above description, the example in which the information management apparatus of the present invention is the image management apparatus 4 installed in the monitoring center has been described. However, the scope of the present invention is not limited to this, and the image recording apparatus If the image management table is stored in the storage unit 20 and the recording processing unit 12 of the image recording device 3 has a function of performing password rewriting processing, the image recording device 3 installed in the monitoring area is The information management apparatus of the present invention may function.

  As described above, the information management apparatus according to the present invention has an effect of improving convenience when a person with appropriate authority handles managed information in which personal identification information is set, and is taken with a surveillance camera. It is used as an image management apparatus that manages image data and is useful.
