Abstract

In digital content distribution systems, digital watermarking (fingerprinting) technique provides a good solution to avoid illegal copying and has been studied very actively. c-secure CRT code is one of the most practical schemes for such fingerprinting since it is secure against collusion attacks even though random errors are added. But it is not sufficiently secure in the case that random errors are added. In this paper, a new ID coding scheme, Randomized c-secure CRT code, is presented. This new scheme improves the error tracing probabilities against collusion attacks with addition of random errors.
