Ensuring integrity and authenticity of digital image files involves encoding image before storage by logic built into camera, storing image in encoded form and preventing decoding by camera

摘要

The method involves encoding the image before storage by logic built into the camera, then storing the image in encoded form and preventing decoding by the camera. A symmetrical or asymmetrical encoding technique can be used and the image data files are provided with at least one additional security feature with which a subsequent alteration of the image data file can be detected. AN Independent claim is also included for the following: (a) a system with a digital camera and a separate organization for decoding and authenticating transmitted image information.
