概要
- 論文の詳細を見る
Many collusion-secure fingerprinting codes drop their performance of traitor tracing when random errors are added on the embedded data. We propose a new tracing algorithm of c-secure CRT code, one of the collusion-secure fingerprinting codes. This algorithm enhances the resilience against the random-error addition by introducing a threshold for distinguishing detected blocks, part of the embedded data altered by the collusion attack. Based on numerical results by computer simulations, this threshold is proved to be practical in decreasing the false tracing rate in the case that both the collusion attack and the random-error addition are done.
