Improved tracing algorithm for random-error-resilient collusion-secure fingerprinting codes in P2P information systems
Ching‐Nung Yang, Bing-Ling Lu · 2006
A randomized c-secure CRT (Chinese Remainder Theorem) fingerprinting code was proposed to avoid the illegal copying of digital content. The tracing algorithm can detect a collusive member from the fingerprinting code generated by a coalition of at most c malicious users. However, the collusion attack and random errors increase the tracing error rate. In this paper, we improve the algorithm to achieve a more reliable tracing.
