We consider a particular design of fingerprinting code for multimedia contents, carefully motivated by a detailed analysis. This design is based on a two-layer approach: a probabilistic fingerprinting code a la Tardos coupled with a zero-bit side informed watermarking technique. The detection of multiple watermark presences in content blocks give birth to extended accusation processes, whose performances, assessed experimentally, are excellent. This prevents the colluders from mixing different content blocks, a class of collusion which is not encompassed in the classical marking assumption. Therefore, the collusion must stick to the block exchange strategy which is fully tackled by the fingerprinting code.
