We investigate alternative suspicion functions for Tardos traitor tracing schemes. In the simple decoder approach (computation of a score for every user independently) we derive suspicion functions th...
Accusation probabilities in Tardos codes: the Gaussian approximation is better than we thought

We study the probability distribution of user accusations in the q-ary Tardos fingerprinting system under the Marking Assumption, in the restricted digit model. In particular, we look at the applicabi...

We introduce a new attack model for collusion secure codes, and analyze the collusion resistance of two
version of the Tardos code in this model, both for binary and non-binary alphabets. The model a...

It has been known that the code lengths of Tardos’s collusion-secure
fingerprinting codes are of theoretically minimal order with respect to
the number of adversarial users (pirates). However, the c...

Fingerprinting provides a means of tracing unauthorized redistribution of digital data by individually marking each authorized copy with a personalized serial number. In order to prevent a group of us...
