Improved Tracing Algorithms for Resistance Error and Attacks Identity Recognition Code
It proposes multimedia encryption at different points to resist some attacks points,and proposes rewritable fingerprint embedding to deal with some multi-point collusion attacks.We examine the possibilities of designing fingerprinting codes that are resistant to tampering.We show that under certain assumptions,we are often able to protect blameless users and even trace back the criminals.Also,with the model we describe,the result of tracing should be reliable.That is,our tracing may fail in the sense that no pirates are identified,but we should not mistakenly accuse an innocent user.So,it proposes improved a new tracing method based on probabilistic method.After then,by the detailed observation of the original algorithm,we modify the parameters in the original tracing algorithm to enhance the efficiency more directly.From the experimental results,our proposed tracing algorithms are more efficiency and correctly.
