Towards joint decoding of Tardos fingerprinting codes
The class of joint decoder of probabilistic fingerprinting codes is of utmost importance in theoretical papers to establish the concept of fingerprint capacity [1]–[3]. However, no implementation supporting a large user base is known to date. This paper presents an iterative decoder which is, as far as we are aware of, the first practical attempt towards joint decoding. The discriminative featu...
متن کاملAn improvement of discrete Tardos fingerprinting codes
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 code lengths can be further reduced, as some preceding studies on Tardos’s codes already revealed. In this article we improve a recent discrete variant of Tardos’s codes, and give a security proof of ...
متن کاملOn the Design and Optimization of Tardos Probabilistic Fingerprinting Codes
G. Tardos [1] was the first to give a construction of a fingerprinting code whose length meets the lowest known bound inO(c log n 1 ). This was a real breakthrough because the construction is very simple. Its efficiency comes from its probabilistic nature. However, although G. Tardos almost gave no argument of his rationale, many parameters of his code are precisely fine-tuned. This paper propo...
متن کاملAsymptotic Fingerprinting Capacity in the Combined Digit Model
We study the channel capacity of q-ary fingerprinting in the limit of large attacker coalitions. We extend known results by considering the Combined Digit Model, an attacker model that captures signal processing attacks such as averaging and noise addition. For q = 2 we give results for various attack parameter settings. For q ≥ 3 we present the relevant equations without providing a solution. ...

The class of joint decoder of probabilistic fingerprinting codes is of utmost importance in theoretical papers to establish the concept of fingerprint capacity [1]–[3]. However, no implementation supporting a large user base is known to date. This article presents an iterative decoder which is, as far as we are aware of, the first practical attempt towards joint decoding. The discriminative fea...
