“…Thus, using a trusted third party is a price worth paying if it can turn a fingerprinting scheme into a practical alternative (Martínez-Ballesté, Sebé, Domingo-Ferrer, & Soriano, 2003). A buyer-seller watermarking scheme (Phan, Goi, Poh, & Jongsung, 2011;Rial, Deng, Bianchi, Piva, & Preneel, 2010) incorporates both watermarking and fingerprinting mechanisms to protect the rights of both the content provider (merchant) and the customer (buyer). A complete and sound buyer-seller watermarking protocol is expected to solve the following requirements (Deng & Preneel, 2008):…”

The use of Peer-to-Peer (P2P) networks for multimedia distribution has spread out globally in recent years. The mass popularity is primarily driven by efficient distribution of content, also giving rise to piracy. An end user (buyer) of a P2P content distribution system does not want to reveal his/her identity during a transaction with a content owner (merchant), whereas the merchant does not want the buyer to further distribute the content illegally. Therefore, there is a strong need for a content distribution mechanism over P2P networks that do not pose security and privacy threats to the copyright holders and end users, respectively. The existent systems for copyright and privacy protection employ cryptographic mechanisms at a cost of high computational burden which makes these systems impractical to distribute large sized files, such as music albums or movies. In this paper, we propose and analyse a P2P content distribution system which allows efficient distribution of large-sized content while preserving the security and privacy of merchants and buyers, respectively. Our proposed framework is able to resolve the problems of piracy tracing, buyer frameproofness, collusion resistance, dispute resolution and buyer's anonymity. We have carried out simulations to evaluate the performance of our framework in terms of imperceptibility, robustness, throughput and content delivery costs. The experimental results confirm that the proposed framework provides an efficient solution to copyright infringement issues over P2P networks, reducing the multimedia file sizes as much as five times on average, while protecting the end users' privacy and anonymity.

“…It is almost the same for the response of the expert. We retrieve an issue of traitor tracing, as in VOD scenario, similar to which an appropriate solution consists in using homomorphic encryption [10][11][12]. In that case, our protocol remains the same.…”

“…Nowadays, different protocols [8][9][10][11][12][13][14][15][16][17][18][19] combine them in order to benefit from the complementarity of these two mechanisms in terms of a priori/a posteriori protection, and consequently to provide a better security response. Most of them focus on the copyright protection in the framework of video on demand (VOD), where the objective is to identify the person (issuer or recipient) at the origin of an illegal distribution by mean of a watermark (a fingerprint).…”

“…The main aim is to achieve a high level of efficiency in applying the watermark protection, since the adopted enciphering scheme only involves computations of modular additions, whereas the other schemes based on homomorphic encryption require computations of modular exponentiations, which are much more expensive than modular additions. The protocol described in [9] is mainly based on two security primitives: group signatures and homomorphic encryption. The former primitive allows buyers to sign the purchase messages they send to the seller on behalf of the group of buyers.…”

The advances in multimedia and networking technologies enable copyright infringement of digital content distributed on Internet. Such infringement, particularly promoted by peer-to-peer file-sharing, causes copyright holders lost sales every year. Consequently, methods to protect digital copyright protection are needed in a global Internet environment. Watermarking protocols are recognized as a promising technique developed to address the problem of asserting authorship and determining accountability when piracy occurs. In this paper, a simple watermarking protocol purposely designed to be easily implemented in the current model of content distribution on the Internet is proposed. The protocol is secure and able to protect the digital asset of the web-based distribution and associated rights.
