[Control structure]
With reference to FIG. 6 and FIG. 7, a control structure of the information management apparatus 100 according to the first embodiment will be described. In addition, the premise of this Embodiment as an example is as follows. Mr. A owns the information management apparatus 100 and the digital camera 300. The information management apparatus 100 is realized by a PC managed by Mr. A, for example.

  An application program necessary for using the digital camera 300 is installed in the information management apparatus 100. In order to execute the application program, camera device specifying information 352 and user information 353 of the digital camera 300 may be required. Further, depending on the function provided by the application program, the information management apparatus 100 connects to the server 20 that provides the function via the Internet 10 and transmits device information and user information to the server 20. When the server 20 receives the camera device identification information 352 and the user information 353 from the information management apparatus 100, the server 20 stores the camera device identification information 352 and the user information in a user database secured as an application user.

  In the information management apparatus 100, the camera device identification information 452 stored in the digital camera 400 of Mr. B is not registered.

  FIG. 6 and FIG. 7 are flowcharts showing a procedure of processing executed by the CPU 1 provided in the information management apparatus 100, respectively. The processing is realized by the CPU 1 executing a program stored in the information management apparatus 100.

  In step S610, the CPU 1 detects the connection between the information management apparatus 100, which is Mr. A's PC, and Mr. B's digital camera 400, and starts the application program 210.

  In step S <b> 620, the CPU 1 acquires the camera device identification information 452 of the digital camera 400 from the digital camera 400 of Mr. B via the communication interface 7.

  In step S630, the CPU 1 reads the user information 230 of Mr. A from the hard disk 5 and loads the read user information 230 into the RAM 4.

  In step S640, CPU 1 determines whether or not user A's user information 230 is encrypted. This determination is made based on, for example, whether the user information 230 can be read in a predetermined format. Alternatively, the determination is made based on attribute data indicating whether the user information 230 is encrypted. The attribute data can be included in the user information 230.

  When CPU 1 determines that user information 230 is encrypted (YES in step S640), CPU 1 switches control to step S650. If not (NO in step S640), CPU 1 switches control to step S700.

  In step S700, CPU 1 executes an encryption process to be described later. When this process is executed, Mr. A's user information 230 is encrypted. Note that the type of encryption processing is not particularly limited.

  In step S650, CPU 1 determines whether or not user A's user information 230 is to be registered. This determination is performed based on, for example, an instruction given to the information management apparatus 100 or based on setting contents input in advance in the information management apparatus 100. When CPU 1 determines to register user information 230 (YES in step S650), CPU 1 switches control to step S660. If not (NO in step S650), CPU 1 switches control to step S670.

  In step S <b> 660, CPU 1 registers camera device specifying information 220 and encrypted user information 230 in association with server 20. For example, the CPU 1 establishes a communication session with the server 20 and accesses a URL (Uniform Resource Locator) required by an application program used by the digital camera 300. In response to a request from the URL site, the CPU 1 transmits user information 230 and camera device identification information 220 to the server 20. The site stores the camera device identification information 220 and user information 230 received from the information management apparatus 100 in the database of the user.

  In step S670, CPU 1 associates camera device specifying information 220 with encrypted user information 230 and stores them in information management apparatus 100, which is Mr. A's PC.

  In step S 680, the CPU 1 stores Mr. A's encrypted user information 230 in Mr. B's digital camera 400 via the communication interface 7.

  In step S690, CPU 1 transmits to digital camera 400 an instruction for deleting the installer and the application program from digital camera 400. If the digital camera 400 is set to delete the installer or application program in response to the instruction, the digital camera 400 deletes the installer and the application program based on the instruction.

  Referring to FIG. 7, in step S710, CPU 1 determines whether or not user A's user information 230 is to be encrypted. This determination is made according to the content of necessity of encryption given to the information management apparatus 100, for example. When CPU 1 determines to encrypt user information 230 (YES in step S710), control is switched to step S720. If not (NO in step S710), CPU 1 returns control to the main process and executes the process of step S650.

  In step S720, CPU1 encrypts user information 230 of Mr. A. In the encryption, for example, authentication information stored in the information management apparatus 100 when Mr. A first connects the digital camera 300 to a computer as the information management apparatus 100 can be used. The authentication information may include, for example, identification information of the PC, camera device identification information 220 of the digital camera 300, date and time when the application program is installed, and the like.

  In step S <b> 730, the CPU 1 stores the user information 230 of Mr. A in the information management apparatus 100 as encrypted user information. Thereafter, the process returns to the main process, and the process of step S650 is executed.

  As described above, when Mr. A's digital camera 300 is connected, the information management apparatus 100 according to the present embodiment encrypts the user information 230 stored in the digital camera 300. Therefore, even if Mr. B connects the digital camera 400 to the information management apparatus 100, Mr. B cannot refer to the user information 230 of Mr. A using the digital camera 400. Information 230 is protected.

Note that the same step numbers are assigned to the same processes as those in the first embodiment described above. Therefore, those descriptions are not repeated.

  In step S640, CPU 1 determines whether or not user A's user information 230 is encrypted. When CPU 1 determines that user information 230 is encrypted (YES in step S640), CPU 1 switches control to step S900. If not (NO in step S640), CPU 1 switches control to step S700.

  In step S900, the CPU 1 executes a decryption process described later. When this process is executed, the encrypted user information is decrypted.

  Referring to FIG. 9, in step S910, CPU 1 determines whether or not user A's user information 230 is to be decrypted. This determination is made, for example, according to the instruction content given to information management device 100. When CPU 1 determines to decrypt user information 230 (YES in step S910), CPU 1 switches control to step S920. If not (NO in step S910), CPU 1 returns control to the main process, and executes the process in step S650.

In step S920, CPU 1 decrypts user A's user information 230.
In step S930, the CPU 1 stores the user information of Mr. A in the PC used by Mr. A (that is, the information management apparatus 100). Thereafter, the process returns to the main process, and the process of step S650 is executed.
