Abstract

Multimedia authentication techniques are required to prove the validity of legal multimedia content and establish the identity of the content creator. Digital signatures are one way of authenticating multimedia content. Typically digital signatures use cryptographic techniques to ensure the integrity of the multimedia bitstream. This paper proposes a hard video authentication and sender verification scheme for video sequences compressed using H.264/AVC Main Profile by using digital signatures and cryptographic hash. Features from the transform domain are used as the authentication data for a macroblock. The algorithm can also detect the cause of authentication failure and point out the location of the tampered frames in case of frame tampering. Results demonstrate that the proposed scheme is highly robust to temporal and spatial manipulations.
