Robust fingerprinting codes and applications

Abstract / Description of output

We discuss the notion of fingerprinting systems for digital objects. We focus on the two-layered concatenating approach in the design of such systems that relies on a suitable notion of equivalence between vector objects. We point to the fact that the primitive of robust fingerprinting codes put forth recently by Boneh and Naor can be useful in the design of general fingerprinting systems as it can be employed over a relaxed notion of object equivalence. We then present a complete analysis that demonstrates that the original Tardos’ codes distribution coupled with a suitable tracing algorithm possesses some level of robustness for sufficiently small
rates of adversarial signal loss.
