Owners and censors

Ic Censors

We introduce an adaptive search technique that speeds up state space search by learning heuristic censors while searching. The censors speed up search by pruning away moTe and more of the space until a solution is found in the pruned space. Censors are learned by explaining dead ends and other search failures. To learn quickly, the technique over-generalizes by assuming that certain constraints...

A Taxonomy of Censors and Anti-Censors: Part I-Impacts of Internet Censorship

The tug-of-war on the Internet between censor and anti-censor technologies is intensifying. With an aim to raise awareness on Internet censorship and its circumvention, this paper and its companion Part II present a conceptual study of Internet censorship and anti-censorship. This first paper focuses on Internet censorship. It outlines an historical account of censorship through the lens of new...

A Taxonomy of Censors and Anti-Censors Part II: Anti-Censorship Technologies

This paper presents a conceptual study of Internet anti-censorship technologies. It begins with an overview of previous research on Internet anti-censorship systems and discusses their social, political and technological dimensions. Then for deployed Internet anti-censorship technologies, a taxonomy of their principles and techniques is presented, followed by a discussion of observed trends and...

Censors for Boolean Description Logic

Protecting different kinds of information has become an important area of research. One aspect is to provide effective means to avoid that secrets can be deduced from the answers of legitimate queries. In the context of atomic propositional databases several methods have been developed to achieve this goal. However, in those databases it is not possible to formalize structural information. Also...
