Information-embedding apparatus and method, tampering-detecting apparatus and method, and recording medium

摘要

An inherent information-generating unit is operable to generate inherent information inherent to each frame image that forms part of moving image data. An information-embedding unit is operable to embed inherent information on a specific frame image as tampering-detecting information into a different frame image in which the inherent information is to be embedded. The specific frame image is temporally separated in position from the different frame image.
