“…However, in the last years, new experiences have been conducted in developing watermarking protocols. Most of them are based on the removal of WCAs from the protocols [30,31,32,33,34], since such authorities could give rise to potential collusion actions with buyers or sellers [35,36,37], thus weakening the security of the protocols. Nonetheless, the result of such experiences is often represented by inefficient watermarking protocols unsuited for the current web context, in which buyers are forced to perform complex security actions, if they want to complete their purchase transactions.…”

Copyright protection of digital content is considered a relevant problem of the current Internet since content digitalization and high performance interconnection networks have greatly increased the possibilities to reproduce and distribute digital content. Digital Rights Management (DRM) systems try to prevent the inappropriate or illegal use of copyrighted digital content. They are promoted by the major global media players, but they are also perceived as proprietary solutions that give rise to classic problems of privacy and fair use. On the other hand, watermarking protocols have become a possible solution to the problem of copyright protection. They have evolved during the last decade, and interesting proposals have been designed. This paper first presents current trends concerning the most significant solutions to the problem of copyright protection based on DRM systems and then focuses on the most promising approaches in the field of watermarking protocols. In this regard, the examined protocols are discussed in order to individuate which of them can better represent the right trade-off between opposite goals, such as, for example, security and easy of use, so as to prove that it is possible to implement open solutions compatible with the current web context without resorting to proprietary architectures or impairing the protection of copyrighted digital content.

“…Even if a watermarking protocol solves the problems reported above, it has also to face the challenges posed by the current trends in the field of copyright protection of digital content distributed on the Internet [23,30,32,33,34,40,41,42,43,45,46,47,56,57,58].…”

“…However, such a solution is not always possible, since protocols often need TTPs to validate specific data, or some phases of the protocol, or, for example, the plug-ins that have to be downloaded and installed in the buyers' web browsers to complete the purchase transactions [22,23]. Furthermore, when TTPs play a limited role in the protocols, buyers end up being forced to perform complex security actions to complete the purchase transactions, and this makes the protocols impractical for the web context [17][18][19][20][21][40][41][42][43][44].…”

“…However, the introduction of WCAs can reduce the security level of the protocols, since TTPs can give rise to potential collusive behaviors with buyers or sellers [2,16]. As a consequence, a number of watermarking protocols are based on "simplified" interaction schemes that do not exploit WCAs [17][18][19][20][21]. Such approaches appear to be more secure, but they turn out to be impracticable in the current web context, since they are characterized by interaction schemes that force buyers to perform complex security actions to complete content purchase transactions [22].…”

Digital watermarking can be used to implement mechanisms aimed at protecting the copyright of digital content distributed on the Internet. Such mechanisms support copyright identification and content tracking by enabling content providers to embed perceptually invisible watermarks into the distributed copies of content. They are employed in conjunction with watermarking protocols, which define the schemes of the web transactions by which buyers can securely purchase protected digital content distributed by content providers. In this regard, the “buyer friendly” and “mediated” watermarking protocols can ensure both a correct content protection and an easy participation of buyers in the transactions by which to purchase the distributed content. They represent a valid alternative to the classic “buyer and seller” watermarking protocols documented in the literature. However, their protection schemes could be further improved and simplified. This paper presents a new watermarking protocol able to combine the “buyer friendly” and “mediated” design approach with the blockchain technology. The result is a secure protocol that can support a limited and balanced participation of both buyers and content providers in the purchase transactions of protected digital content. Moreover, the protocol can avoid the direct involvement of trusted third parties in the purchase transactions. This can reduce the actual risk that buyers or sellers can violate the protocol by illicitly interacting with trusted third parties. In fact, such peculiarities make the proposed protocol suited for the current web context.

“…Reversible watermarking is designed so that it can be removed completely to restore the original image (Thodi and Rodriguez, 2007;Alattar, 2004;Ni et al, 2006;Vleeschouwer et al, 2001;Weng et al, 2008;Lee et al, 2007). Considering the age of reversible watermarking which is just a decade to count, it has fetched enormous attention of researchers to boost of (Mehta et al, 2012;Xu, 2012). In reversible watermarking, we embed a watermark in a digital image I, and obtain the watermarked image I′.…”

Reversible data embedding has drawn lots of interest recently, specially in the field of protection for cultural heritage and medical image. Being reversible, the original digital content can be completely restored. This paper uses Tian's algorithm of difference expansion as reversible watermarking scheme for the protection of cultural heritage and medical image. Lifting together with channel coding is used to increase the detection performance of extracted watermark bits. Experimental results and performance comparison with other reversible data hiding schemes are presented to demonstrate the validity of the proposed algorithm.
