摘要

Provided is a digital video content security authentication method. The method comprises: a secret information embedding step: selectively modifying a pixel grey-scale value for each frame image in a digital video, so as to complete the embedding of one-bit secret information; and a secret information extraction and video authentication step: extracting the secret information from the digital video embedded with the secret information according to a key, so as to realize the authentication on digital video content security. Also provided is a digital video content security authentication system. According to the technical solution provided in the present invention, the authentication security can be improved on the basis that the user experience is not affected.
