“…More precisely, DRM systems do not actually define watermarking protocols, but they still implement mechanisms by which to prevent the unauthorized use of protected digital content without payment. To achieve such a goal, DRM systems use technologies based on encryption and key management [34]. However, such technologies cannot inhibit legitimate users from illegally sharing their purchased content on the Internet.…”

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.

“…Existing mainstream or novel DRM mechanisms include but are not limited to encapsulated encryption and confusion [2,3,4,5], digital watermarks [6,7,8,9,10,11,12,13,14], blockchain [15,16], trusted computing [17,18], biological features [19], etc. After reviewing the previous schemes, we believe that existing DRM technologies still have great defects.…”

“…In this paper, we propose Y-DWMS, a digital watermarking management system based on a public smart contract platform. We summarize the contributions of the paper as follows:Y-DWMS can effectively recover losses of copyright holders and track infringers, reward informers, and punish infringers at the moment of reporting, compared with [4,5,15,17,19,20]. In the common smart contract platform, the punishment of infringers could be compensated by informers if there are malicious smart contracts signed between infringers and informers.…”

“…We adopt game theory to prove that Y-DWMS can increase the cost of copyright infringement to infinity and resist countermeasures by signing smart contracts. Therefore, under the deterrence of Y-DWMS, the decision of non-infringement always dominates rational users.Y-DWMS is independent from unique hardware, is flexible, and has weak restrictions on distribution of copies, compared with [4,5,17,19]. …”

With the development of information technology, films, music, and other publications are inclined to be distributed in digitalized form. However, the low cost of data replication and dissemination leads to digital rights problems and brings huge economic losses. Up to now, existing digital rights management (DRM) schemes have been powerless to deter attempts of infringing digital rights and recover losses of copyright holders. This paper presents a YODA-based digital watermark management system (Y-DWMS), adopting non-repudiation of smart contract and blockchain, to implement a DRM mechanism to infinitely amplify the cost of infringement and recover losses copyright holders suffered once the infringement is reported. We adopt game analysis to prove that in Y-DWMS, the decision of non-infringement always dominates rational users, so as to fundamentally eradicate the infringement of digital rights, which current mainstream DRM schemes cannot reach.

Vehicle sensors are continuously observing the state of the vehicle, collecting and transmitting data from/to surrounding road users. The sensors data are then processed and stored in an in-vehicle sensor database in the form of records.These records can be accessed and shared by other vehicles or road side units with the aim to improve road safety. However, these records may contain a very sensitive information, such as vehicles' identifiers and location. This information requires extraordinary protection to ensure privacy and confidentiality of the vehicle users. In this article, we propose a secure oblivious transfer protocol with hidden access control and outsourced decryption from deterministic finite automata (DFA)-based functional encryption (HACOT-DFA). To reduce the computational costs for users with limited resources, we securely offload the heavy decryption overhead on the user side to an untrusted cloud server.Then, we experimentally compare our HACOT-DFA protocol against existing HACOT protocols in three different platform settings: the smartphone, the desktop personal computer, and the embedded device Raspberry Pi. The analyses demonstrate that the proposed HACOT-DFA protocol is more efficient and computationally stable than previous work. Our security proof holds in the standard model using a dual-system encryption approach.
