Research on Image Fingerprint Technology Based on Watson Visual Model Multimedia Technology

摘要: Computer network has greatly changed the life and work of people, demand people for information been developed from single text message to current graphics, images, audio, video other digital multimedia forms. With development a large number applications, image is easy be operated tampered, this paper aims study an fingerprint algorithm based on masking characteristics human eye. An sensing Hash visual model proposed effectively eliminate influence geometric attacks. Watson used deal with DCT coefficients produce sequences, which excellent robustness security. The experiment proves that can certify copyright image, reduce attacks, JPEG compression it also use key generate pseudo-random matrix, so as encrypt realize security algorithm.
