Y-DWMS: A Digital Watermark Management System Based on Smart Contracts.

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.

Secure and efficient digital rights management mechanisms with privacy protection

In the Internet or cloud computing environments, service providers provide more and more content services. Users can use these convenient content services in daily life. The major data of the user are maintained by the service providers except that some personal privacy data are stored at the client device. An attacker may try to invade the systems, and it will cause the damage of users and service providers. Also, users may lose their mobile devices and then it may cause the data disclosure problem. As a result, the data and privacy protection of users become an important issue in these environments. Besides, since many mobile devices are used in these environments, secure authentication and data protection methods must be efficient in these low resource environments. In this paper, we propose an efficient and privacy protection digital rights management (DRM) scheme that users can verify the valid service servers and the service servers can ensure the legal users. Since the key delegation center of the third party has the robust security protection, our proposed scheme stores the encrypted secret keys in the key delegation center. This approach not only can reduce the storage space of the user devices, but also can recover the encrypted secret keys in the key delegation center when a user loses her/his devices for solving the device losing problem.

The design of authentication key protocol in certificate‐free public key cryptosystem

ABSTRACTIn regard to the communication security of open networks, authenticated key management agreements are able to provide confidentiality, integrity, and verification so as to establish a more secure and fair digital rights management mechanism. For this reason, this paper, aiming at authentication key management agreements, tends to provide a security study on the application of authentication key management agreements, covering the establishment, analysis, design, security study, and performance optimization in various environments. Based on present public key schemes, such as public key cryptography, identity‐recognized cryptography, and undocumented cryptography, it aims to establish an authenticated key management agreement suitable for various application environments. Using the one‐way transmission in identity‐recognized cryptography or undocumented cryptography for formulating practical and effective security models, it tends to establish the one‐way authentication key agreement for both parties. Based on the design of single authentication key, an authentication key agreement for the undocumented public key cryptography is proposed to design a security model for the secure and high‐efficiency undocumented two‐party authentication key agreement. Under random oracle model and standard model, the security of the undocumented two‐party authentication key agreement is authenticated. Furthermore, aiming at the computational efficiency, communication efficiency, and key exchange frequency of group key management agreements, this paper aims to propose a method for dynamic membership. Besides, regarding the secure communication environment in different application backgrounds, such as the network applications of Grid, P2P, and ad‐hoc, it would propose practical group key agreements for networks and multi‐node communications to promote the security of group key management and to facilitate the computation of agreements and the optimization of communications.

A practical secure and efficient enterprise digital rights management mechanism suitable for mobile environment

ABSTRACTDigital rights management (DRM) is a term for access control technologies that are used by hardware manufacturers, publishers, copyright holders, and individuals to limit the use of digital content and devices. Enterprise digital rights management (E‐DRM) is the application of DRM technology to prevent illegal users from accessing the confidential data of an enterprise. In 2010, Chang et al. proposed an efficient E‐DRM scheme to solve the flaws of Chen's scheme. However, we still found some weaknesses in their scheme. In this article, we propose an improved secure and efficient E‐DRM mechanism based on a one‐way hash function and exclusive‐or. Our mechanism overcomes the weaknesses in the scheme of Chang et al. and also reduces computation costs. In addition, we used BAN logic to show the correctness of our mechanism.

Abstract:Due to the absence of actual obligation description and implementation abilities in existing DRM (digital rights management) mechanism, this paper presents an obligation authorization model and its implementation framework that can be applied in DRM. The model is based on distributed temporal logic and Active-U-Datalog rules, which empowers the model to express event-driven, time-driven, obligation compensation and other semantics of obligation descriptions, and also give the model a favorable feasibility of implementation. The semantics and syntax of the model are analyzed and explained. And the implementation mechanism of the model is discussed. Finally, the implementation, application and expressiveness of the model are showed and illustrated. The model improves the flexibility and capability of usage control of data in DRM system. 参考文献 相似文献 引证文献

Digital rights management for multimedia content over 3G mobile networks

Third generation (3G) mobile systems offer true broadband data transmission and many multimedia services are flourishing on them. Hence, 3G transmission security has become a popular issue. Recently, Dimitriadis and Polemi proposed a lightweight IDM3G protocol for mutual authentication between users and their service providers. However, many multimedia services require safeguards during transmission over 3G networks to protect the digital rights of music and video, for example. Unfortunately, the Dimitriadis and Polemi protocol does not address this requirement in their protocol, which means their protocol can not be directly applied to design a fair and secure digital rights management mechanism. Therefore, in this paper, we try to improve their protocol by integrating the identity management 3G (IDM3G) and then propose a fair and secure digital rights management mechanism for multimedia content or services over 3G networks. Using our proposed scheme enables service providers to provide time-bounded multimedia content or services and guarantees user privacy, data integrity, confidentiality, and non-repudiation, as well as forward secrecy and backward secrecy of transferred digital rights with low computation costs.

Production Protection to Copy(right) Protection: From the 10NES to DVDs

Much of what modern digital rights management (DRM) systems attempt to accomplish was actually forcefully implemented on videogame consoles beginning with the Nintendo Entertainment System (NES) and SEGA Genesis system in the early 1980s. Examining the links between modern DRM mechanisms and these early production and copy protection systems can help contextualize the future of media production and access.
