As the sophistication and proliferation of digital media continues to increase, so to do methods which seek to compromise data integrity. Digital authentication can be a critical component to ensuring reliability and security in digital video surveillance platforms. A robust method of encoding video can provide authentication ensuring that data has not been compromised and is still reliable. By watermarking motion vectors in a video stream, it is possible to authenticate said video and ensure it has not been compromised. Our proposed authentication scheme provides a secure method of ensuring data integrity that is simple to encode yet difficult to emulate. The proposed method is not computationally complex, produces almost no visual distortion, and can be accomplished in real-time.
