“…This is understood as a necessary trade-off between the interest of data protection and law enforcement: anonymity services are susceptible to be abused for criminal activities. In such cases, anonymity should indeed be revocable (though other means than data retention have been proposed to achieve this end [1,2]). …”

Abstract.The recently introduced legislation on data retention to aid prosecuting cyber-related crime in Europe also affects the achievable security of systems for anonymous communication on the Internet. We argue that data retention requires a review of existing security evaluations against a new class of realistic adversary models. In particular, we present theoretical results and first empirical evidence for intersection attacks by law enforcement authorities. The reference architecture for our study is the anonymity service AN.ON, from which we also collect empirical data. Our adversary model reflects an interpretation of the current implementation of the EC Directive on Data Retention in Germany.

Online social networks (OSN) have now become one of the most widely used Internet applications with a huge base of online users. In an OSN, the users exchange their personal information via messages, pictures and videos with their online peers/friends for their personal or business interests. Since the information that flows across an OSN is generally of personal in nature, it is important that the users get the assurance that their personal information is kept private to a level that they desire. In this paper, we first analyze a distributed OSN framework called Safebook, in which the privacy of the users' information is preserved. As part of our analysis, we also suggest improvements to some of the approaches followed in Safebook in achieving its features. We then apply the techniques of threshold cryptography to Safebook for achieving reliability and onion routing for user anonymity thereby enhancing the security and performance of Safebook.

“…Two years after deployment, it counts hundreds of volunteer nodes and hundreds of thousands of users, making it a very successful anonymous communication network. Claessens et al propose in [10] a system for revocable anonymous communication based on blind signatures. They introduce the legal requirements relevant for (revocable) anonymous communication and present a proof-of-concept architecture.…”

Decreased privacy is an unavoidable consequence in the drive to make the world a more secure, safer place, according to some analysts. In the on-line world, the conflict between privacy and security manifests itself in a debate between anonymity and accountability. Balance between Anonymity and Accountability is a major concern in web based transactions. The protection of users' privacy when performing web-based transactions is an important factor in the acceptance and use of Internet and web services. There is a tremendous improvement in the automation of the way we pay for goods and services by the variety and growth of electronic banking services available to the consumers. Hence there is a need for the ultimate structure of the new electronic transaction system that has a substantial impact on the personal privacy as well as on the nature and extent of criminal use of E-transactions. This paper presents an approach for such structure.
