As described above, where shooting restrictions are required, it is possible to provide an image taken under certain conditions while restricting shooting as a print image.

In this embodiment, when transmitting the original image data and the print request information to the printing apparatus (see S81 in FIG. 8), the original image data and the information about the address and the like included in the print request information It is also possible to transmit the print order information after encrypting it.
In S73 to 75, the camera ID, the image ID, and the print order information can be transmitted to the management server 2 together with the encryption key without being encrypted. In this case, the encryption key and the decryption key are not generated in S71 to S72, and the camera ID is not decrypted and the image ID and the print order information are not decrypted in S76 and S78.

  On the other hand, the same steps as the accounting process described in FIG. 8 may be added to the first embodiment. In this case, the original image data itself is provided for a fee. The fee is determined according to the number of images selected in S42 and acquired in S55. Withdraw the charge from the user's payment account. It should be noted that the size of the image data can be specified, and the charge may vary depending on the size. In this case, the image resizing process is performed to the size designated by the user before the original image data in S54 is encrypted.

In this embodiment, the digital camera 1 encrypts and stores the original image data relating to the photographed original image, and the image is provided by decrypting it using the decryption key transmitted from the management server 2. It is what I do.
FIG. 9 is a block diagram illustrating the configuration of the imaging management system according to the third embodiment of the present invention.

  As shown in the figure, this system includes a digital camera 1 having a watermark synthesizing unit 36 that synthesizes watermark data and an interface 37 that transmits and receives information between external devices connected to the digital camera 1. Furthermore, the system according to the first embodiment is that the encryption key generation unit 12 is omitted and the management server 2 includes a watermark generation unit 38 that generates watermark data instead of the watermark synthesis unit 23 (FIG. 1). Unlike the reference), other configurations are the same.

In the system according to the present embodiment, the operation shown in FIG. 10 is performed as follows. First, the above-described processing of S1 (see FIG. 2) is performed, and then the original image (original image data) is encrypted and stored. And the processing shown in FIG. 11 for decrypting the encrypted original image is performed.
FIG. 10 is a flowchart showing the above-described processing contents for photographing and encrypting and saving the original image.

In the figure, S111 to 115, S119 to 123, and S128 indicate the operation of the digital camera 1, and S116 to 118 and S124 to 127 indicate the operation of the management server 2.
First, when the digital camera 1 detects that the user has pressed the shutter button (S111), the processing of S112 to S114 and the processing of S115 are performed in parallel. In S112 to S114, processing similar to S22 to S24 (see FIG. 4) is performed. In S115, a request signal for the encryption key and watermark data is transmitted from the communication unit 14 to the management server 2.

  In the management server 2, when the communication unit 24 receives the request signal for the encryption key and watermark data, the encryption key generation unit 22 generates an encryption key and a corresponding decryption key (S116), and the watermark generation unit 38 Watermark data is generated (S117). Then, the encryption key generated in S116 and the watermark data generated in S117 are transmitted from the communication unit 24 to the digital camera 1 (S118).

  In the digital camera 1, when the communication unit 14 receives the encryption key and the watermark data, the watermark data is combined with the original image data obtained in S112 by the watermark data combining unit 36 (S119). The original image data is encrypted by the encryption / decryption unit 6 (S120). Subsequently, the encrypted original image data and the thumbnail image data generated in S113 are stored in the image memory 9 in association with the image ID generated in S114 (S121). The encryption in S120 is performed using the encryption key acquired from the management server 2. Subsequently, the image ID generated in S114 and the camera ID stored in the camera ID memory 5 are encrypted by the encryption / decryption unit 6 (S122), and the encrypted image ID and camera ID are It is transmitted from the communication unit 14 to the management server 2 (S123). The encryption in S122 is performed using the encryption key acquired from the management server 2.

  In the management server 2, when the communication unit 24 receives the encrypted image ID and camera ID, the encrypted image ID and camera ID are decrypted by the encryption / decryption unit 20 (S124). Then, authentication of the camera ID is performed (S125), and if it is authenticated that the camera ID is valid, the processing after S126 is executed. In S126, the image ID and camera ID decrypted in S124 are associated with the decryption key generated in S116 and stored in the image information DB 18 (S127). Note that the decryption in S124 is performed using the decryption key generated in S118. Subsequently, a decryption key storage result notifying that the decryption key has been stored is transmitted from the communication unit 24 to the digital camera 1 (S127).

In the digital camera 1, when the communication unit 14 receives the decryption key storage result, a photographing completion notification is sent to the user (S128). This photographing completion notification is performed by, for example, displaying the fact on the display unit 10.
The processing from S111 to S128 is repeated every time the shutter of the digital camera 1 is operated.

  When shooting is performed by the processing shown in FIG. 10, the original image data relating to the shot image is encrypted and stored in the image memory 9 of the digital camera 1, and the encrypted original image data is decrypted. The decryption key to be converted is stored in the image information DB 18 of the management server 2.

FIG. 11 is a flowchart showing the processing contents for decrypting the encrypted original image.
In the figure, S131 to 134, S137 to 139, and S146 to 149 indicate the operation of the digital camera 1, and S135 to 136, and S140 to 145 indicate the operation of the management server 2.

  In the figure, the processing of S131 to 142 is the same as the processing of S41 to 52 (see FIG. 5). That is, in S131 to 134, the same processing as S41 to 44 is performed, in S135 to 136, the same processing as S45 to 46 is performed, and in S137 to 139, the same processing as S47 to 49 is performed. In S140 to 142, the same processing as S50 to 52 is performed. Note that the image request signal transmitted in S139 is a decryption key request signal.

  Subsequent to S142, the decoding key of the original image associated with the camera ID decoded in S140 and the image ID decoded in S142 is read from the image information DB 18 (S143), and the decoding key of the original image is read. And the image ID are encrypted by the encryption / decryption unit 20 (S144). This encryption is performed using an encryption key acquired from the digital camera 1. Subsequently, the decryption key and the image ID of the encrypted original image are transmitted from the communication unit 24 to the digital camera 1 (S145).

  In the digital camera 1, when the communication unit 14 receives the decryption key and the image ID of the encrypted original image, the encryption / decryption unit 6 decrypts the encrypted decryption key and the image ID of the original image. (S146). This decryption is performed using the decryption key generated in S134. Subsequently, the encrypted original image data associated with the decrypted image ID is read from the image memory 9 (S147), and the encrypted original image data is decrypted in S146. The encryption / decryption unit 6 decrypts the image using the image decryption key (S148), and the decrypted original image data is stored in the image memory 9 (S149).

  As described above, when a desired thumbnail image is selected from the displayed thumbnail images by the processing shown in FIG. 11, encrypted original image data related to the original image of the thumbnail image is transmitted from the management server 2. Decryption is performed using the transmitted decryption key, and the decrypted original image data is stored in the image memory 9.

The original image data stored in the image memory 9 can be stored in an external storage device connected via the interface 37 as necessary.
