Building efficient and effective multimedia fingerprints via joint coding and embedding

摘要: Digital fingerprinting protects multimedia content from illegal redistribution by uniquely marking every copy of the distributed to each user. One major category collusion-resistant employs an explicit step coding. Most existing works on coded mainly focus code-level issues and treat embedding through abstract assumptions without examining overall performance. In this paper, we jointly consider coding for systems examine their performance in terms collusion resistance, detection computational complexity, distribution efficiency. Our studies show that has efficient but rather low resistance. Taking advantage joint embedding, propose two new techniques, namely, a Permuted Subsegment Embedding technique Group-based Joint Coding (GRACE) technique, improve resistance while maintaining its detection. Experimental results number colluders proposed methods can resist is more than three times as many conventional approaches.
