Collusion-resistant audio fingerprinting system in the modulated complex lapped transform domain.

Garcia-Hernandez JJ, Feregrino-Uribe C, Cumplido R - PLoS ONE (2013)

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: Figure 16 shows the user ID detection system. In similar form that group ID detection, for each available MCLT coefficients block, user detection is carried out according to the threshold, , described in equation (13). For the whole pirate audio clip, there is a counter vector that registers the number of times that each component of exceeds . Counter vector is modeled as a Half-normal distribution and the corresponding threshold for a given is calculated according to:
