A Novel Video Authentication Scheme with Secure CS-Watermark in Cloud

摘要

Data secure processing is the important issue of video authentication in cloud environment. This research presents a novel scheme to protect integrity of video content for common video data operations by using a semi-fragile CS-watermark technology. In proposed scheme, the CS-watermark data are generated from the block compressed sensing (CS) measurements which rely on the knowledge of the measurement matrix used for sensing I frame's DCT coefficients. Our analysis and results indicate that the CS-watermark data can accurately verify the integrity of the original video content, and have higher security than other watermarking methods.
