Bottom Line: Despite the billionaire losses in the music industry, most of the collusion-resistant fingerprinting systems are devoted to digital images and very few to audio signals.Extensive simulations show the robustness of the proposed system against average collusion attack.Moreover, by using an efficient Fast Fourier Transform core and standard computer machines it is shown that the proposed system is suitable for real-world scenarios.

ABSTRACT
Collusion-resistant fingerprinting paradigm seems to be a practical solution to the piracy problem as it allows media owners to detect any unauthorized copy and trace it back to the dishonest users. Despite the billionaire losses in the music industry, most of the collusion-resistant fingerprinting systems are devoted to digital images and very few to audio signals. In this paper, state-of-the-art collusion-resistant fingerprinting ideas are extended to audio signals and the corresponding parameters and operation conditions are proposed. Moreover, in order to carry out fingerprint detection using just a fraction of the pirate audio clip, block-based embedding and its corresponding detector is proposed. Extensive simulations show the robustness of the proposed system against average collusion attack. Moreover, by using an efficient Fast Fourier Transform core and standard computer machines it is shown that the proposed system is suitable for real-world scenarios.

Mentions: Instead of the group ID detection in each block where the threshold is computed assuming a Gaussian distribution, the threshold, , for detection in the counter vector must consider other distribution as the lower limit of that distribution will always be zero. In order to know the statistical behavior of the counter vector , 120 different fingerprinted audio clips are utilized. Figure 14 shows the distribution of the counter vector .
