Image sensing apparatus for generating image data and authentication data of the image data
摘要:
An image sensing apparatus generates image data corresponding to a sensed image, and generates key data which is used to generate authentication data. The authentication data is used to authenticate whether or not the image data is altered. The image sensing apparatus erases the generated key data from the image sensing apparatus if at least two image data generated by the image sensing apparatus are stored in a memory.
