Subsequently, the camera ID encrypted in S47, the image ID encrypted in S48, and the encryption key generated in S44 are transmitted from the communication unit 14 to the management server 2 (S49).

  In the management server 2, when the communication unit 24 receives the encrypted camera ID, the image ID, and the encryption key, the camera ID is decrypted by the encryption / decryption unit 20 (S50). This decryption is performed using the decryption key generated in S45. Subsequently, authentication of the camera ID decrypted in S50 is performed (S51). Here, as authentication of the camera ID, it is determined whether or not the user information associated with the decrypted camera ID is registered in the management DB 21, and if it is determined that it is registered If the camera ID is valid, the processing from S52 is performed. However, if it is not determined that the camera ID is registered, the processing from S52 is not performed because the camera ID is invalid.

  If the user information associated with the camera ID decrypted in S50 is registered in the management DB 21 in S51, the received image ID is subsequently decrypted by the encryption / decryption unit 20 ( S52). This decryption is performed using the decryption key generated in S45. Subsequently, the original image data associated with the decrypted camera ID and image ID is read from the image information DB 18 (S53), and the original image data is encrypted by the encryption / decryption unit 20 (S54). ). This encryption is performed using an encryption key acquired from the digital camera 1. Subsequently, the encrypted original image data is transmitted from the communication unit 24 to the digital camera 1 (S55).

  In the digital camera 1, when the communication unit 14 receives the encrypted original image data, the encrypted original image data is decrypted by the encryption / decryption unit 6 (S56), and the decrypted original image is obtained. Data is stored in the image memory 9 (S57). Note that the decryption at S56 is performed using the decryption key generated at S44.

When a desired thumbnail image is selected from the displayed thumbnail images by the processing shown in FIG. 5, original image data relating to the original image of the thumbnail image is acquired from the management server 2 and is stored in the image memory. 9 will be saved.
As described above, according to the present embodiment, since only the person who has performed user registration and acquired the camera ID is provided with the original image of the captured image as necessary, such as a concert venue or the like. In a place where shooting restrictions are required, it is possible to provide images taken under certain conditions while restricting shooting. For example, when the number of images is limited, it is possible to acquire the user's favorite image from among a large number of captured images.

  In the present embodiment, for example, a person who requests photographing restrictions can rent and use the digital camera 1 for those who are subject to photographing restrictions. In this case, a person who is subject to shooting restrictions may register user information when the digital camera 1 is rented. However, in this case, the camera ID memory 5 of the digital camera 1 to be rented stores the camera ID in advance, and the registered user information includes the communication address of the digital camera 1 and includes the communication address. User information is associated with the camera ID of the digital camera 1 and registered in the management DB 21 of the management server 2.

  In S55, the encrypted original image data may be transmitted to the destination address designated by the user. In this case, the transmission result information is transmitted to the digital camera 1, and the transmission result information is stored and displayed in S57. The destination address of the original image data is designated in the user information input step of S9.

  In S30 to S31, the original image, the image ID, and the camera ID may be transmitted as they are to the management server 2 without being encrypted. In this case, the generation of the encryption key and the decryption key and the transmission of the encryption key are not performed in S28 to S29, and the original image, the image ID, and the camera ID are not decrypted in S32.

  In S47 to 49, the camera ID and the image ID may be transmitted to the management server 2 together with the encryption key without being encrypted. In this case, the generation of the encryption key and the decryption key and the transmission of the encryption key are not performed in S45 to S46, and the decryption of the camera ID and the decryption of the image ID are not performed in S50 and S52.

In this embodiment, the captured image is provided as a print image, not as original image data.

(S75).

  In the management server 2, when the communication unit 24 receives a print request signal including an encrypted camera ID, an encrypted image ID and print order information, and an encryption key, the encrypted camera ID is Decrypted by the encryption / decryption unit 20 (S76). This decryption is performed using the decryption key generated in S71. Subsequently, the camera ID decrypted in S76 is authenticated (S77). Here, authentication is performed by a method similar to the method described in S51 (see FIG. 5). If the user information associated with the camera ID decrypted in S76 is registered in the management DB 21 in S77, the encrypted image ID and the print order information are subsequently stored in the encryption / decryption unit 20. (S78). This decryption is performed using the decryption key generated in S71. Subsequently, the original image data associated with the camera ID decoded in S76 and the image ID decoded in S78 is read from the image information DB 18 (S79). Subsequently, print request information including information related to the address and the like included in the user information registered in the management DB 21 and the print order information decrypted in S78, which are associated with the camera ID decrypted in S76. Is generated (S80), and the print request information and the original image data read in S79 are transmitted from the communication unit 26 to the printing device of the printer (to the communication address of the printing device) (S81). Subsequently, the printing fee is calculated according to the printing order information decrypted in S78 (S82). Subsequently, the settlement account number included in the user information registered in the management DB 21 associated with the camera ID decrypted in S76 is read from the management DB 21 (S83), and the settlement associated with the settlement account number is read. Processing is performed to withdraw the printing fee calculated in S82 from the account (S84). Subsequently, receipt data is generated as information for notifying that the printing fee has been deducted from the user's settlement account, and encrypted by the encryption / decryption unit 20 (S85). This encryption is performed using an encryption key acquired from the digital camera 1. Subsequently, the receipt data encrypted in S85 is transmitted to the digital camera 1 (S86).

  In the digital camera 1, when the communication unit 14 receives the encrypted receipt data, the encrypted receipt data is decrypted by the encryption / decryption unit 6 (S87), and the decrypted receipt is received. Data is stored in a predetermined memory (for example, the image memory 9) (S88). Note that the decryption in S87 is performed using the decryption key generated in S70.

  When the desired thumbnail image to be printed is selected from the displayed thumbnail images and the print order information is input by the processing shown in FIG. 8, a print request for the original image related to the thumbnail image is made. This is done for the printing company, and the printing fee related to the printing order is withdrawn.

  When the printing apparatus of the printing company receives the original image data and the print request information transmitted from the management server 2, the original image related to the original image data is printed according to the print order information included in the print request information. The Then, the print image is delivered or mailed to a specific address related to the information related to the address or the like included in the print request information, and the user can receive the print image at a later date.
