“…Digital Rights Management (DRM) technology [45,82,85,124,193,196,218] primarily aims at the persistent protection of copyrighted digital content such as images, video, audio, book, games, text, or any combination thereof. In a nutshell, One major drawback of DRM is that it lacks any standards [65].…”

AbstractData usage control provides mechanisms for data owners to remain in control over how their data is used after it has been accessed. Corresponding technical solutions are thus applicable in many distinct areas such as the protection of business, military and government secrets, intellectual property, as well as private user data. However, most existing solutions focus on the enforcement of data usage control within single systems and disregard distributed aspects of data usage control, i.e. how the usage of data can be controlled once data has been shared across systems and organizations.In fact, many data usage policies can only be enforced on a global scale, as they refer to data as well as data usage events happening within several distributed systems, e.g. "at each point in time at most two clerks might have a local copy of this contract", or "a contract must be approved by at least two clerks before it is sent to the customer".While such policies can intuitively be enforced using a centralized infrastructure, major drawbacks are that such solutions constitute a single point of failure and that they are expected to cause heavy communication and performance overheads.In order to address these open challenges, this dissertation contributes by providing (i) a formal distributed data usage control system model, and (ii) the first fully decentralized infrastructure for the preventive enforcement of data usage policies. More precisely, the provided model allows to track the f...

With extensive usage and dependence on communication networks, 'privacy' issues in enterprise distributed systems have become fundamentally important. Privacy concerns have flooded the market especially in the public domain, and with the changing environment of software usage and involvement of malicious substances associated with any network, it becomes essential to safeguard and ascertain privacy among users and incorporate the same safeguard to protect privacy in software as well. The methodologies and tools architecting distributed enterprise resource planning (ERP) systems are primarily new and are vulnerable to malicious attacks. This paper aims at identifying some of critical privacy issues by collecting data from ERP practitioners. This work models variables associated with ERP with the variables of privacy to establish a robust adoption of ERP practices. Privacy issues concerning ERP are listed. Several variables associated with the development, implementation, and control of ERP are identified in the existing literature. A questionnaire instrument was distributed among a set of ERP practitioners. The response data collected thereby were analyzed statistically. Based upon the statistical analysis, an attempt has been made in the paper to make a ranking of the privacy factors. The observations are discussed in detail, and some specific conclusions have been made.

“…These systems are more concerned about security of multimedia data rather than protection of user privacy. Few P2P systems have been proposed that address both security concerns of providers and users' privacy concerns [Megías and Domingo-Ferrer, 2013;Domingo-Ferrer and Megías, 2013;Yen et al, 2013] Cryptography, Digital Rights Management (DRM), and watermarking are digital content protection techniques against piracy. The hidden information, watermark, is used for copyright protection, tamper detection, covert communication, source tracking of leakage, and so forth.…”
