“…The simplex is an ETF with and . In fact, Kiyavash et al [20] give a derivation for the value of the distance (12) in this case (21) The bound (20) is lower than (21) by a factor of , and for practical cases in which , they are particularly close. Overall, ETF fingerprint design is a natural generalization of the provably optimal simplex design of [20].…”

Digital fingerprinting is a framework for marking media files, such as images, music, or movies, with user-specific signatures to deter illegal distribution. Multiple users can collude to produce a forgery that can potentially overcome a fingerprinting system. This paper proposes an equiangular tight frame fingerprint design which is robust to such collusion attacks. We motivate this design by considering digital fingerprinting in terms of compressed sensing. The attack is modeled as linear averaging of multiple marked copies before adding a Gaussian noise vector. The content owner can then determine guilt by exploiting correlation between each user's fingerprint and the forged copy. The worst case error probability of this detection scheme is analyzed and bounded. Simulation results demonstrate that the average-case performance is similar to the performance of orthogonal and simplex fingerprint designs, while accommodating several times as many users.

“…As a variant of the spread spectrum techniques based on the Cox's method, Hayashi et. al have proposed an hierarchical fingerprinting scheme based on the CDMA technique by combining quasiorthogonal sequences and orthogonal transform [8]. It is possible to assign an unique combination of two kinds of SS sequences to each user; one is for group ID which identifies the group where a user belongs to, and the other is for user ID which represents an individual user in the group.…”

Digital fingerprinting is to embed information into multimedia contents in order to trace illegal users who distribute pirated copies. One of the serious problems in a fingerprinting system is collusion attack such that several users combine individual copies to remove/modify the embedded fingerprints. As a technique for resisting collusion attacks, Kuribayashi et. al have proposed hierarchical spread spectrum fingerprinting scheme based on the CDMA technique. In this paper, we focus on the number of IDs assigned to each layer, and adjust the assignment for each layer. By optimizing the number of IDs from the theoretical viewpoint, we can effectively decrease the number of elements to be examined, which result in the decrease of the number of false-positive detection without degrading collusion resistance.

“…For the evaluation of the performance, the attack model in [3] and [4] is the combination of averaging attack and JPEG compression with quality factor 35 %. The reason why JPEG compression is used in the simulation is to add a noise under a realistic environment.…”

“…In order to reduce the computational costs in the conventional spread spectrum fingerprinting schemes, the CDMA-based fingerprinting scheme has been proposed [3]. Different from the random spread spectrum sequence in the conventional schemes, theoretically quasi-orthogonal sequences are designed using a PN sequence combined with orthogonal transform like DCT.…”

We have proposed the CDMA-based fingerprinting scheme in IWSEC2007, and the detector is improved by reducing the interference among colluders' fingerprint signals in IH2008. In this study, we evaluate the false-positive detection when the number of colluders is more than 100, and show the bugs in the design of threshold for the determination of guilty. We fix the bugs and further improve the performance by adaptively calculating proper thresholds.
