IMAGE DATA SALES SYSTEM, IMAGE DATA SALES METHOD, CAMERA, AND SERVER APPARATUS

摘要

In the present invention, a camera ID for specifying a camera that takes images to be sold is registered in a server in advance. The server issues an encryption key when the camera ID is registered, and the camera stores the encryption key and encrypts the camera ID by the encryption key to provide the camera ID to an image file including image data obtained by imaging. The server decrypts the encrypted camera ID provided to the image file transmitted from the user by a decryption key corresponding to the encryption key. If the camera ID obtained by the decryption coincides with the registered camera ID, the server authenticates that the image data included in the image file is imaged by the registered camera and discloses the image data to sell the image data.
