Privacy Preserving Data Mining in Horizontally Distributed Databases
The problem of secure mining of association rules in horizontally partitioned databases. One of the main ingredients in our proposed protocol is a novel secure multi-party protocol for computing the union (or intersection) of private subsets that each of the interacting players hold. Another ingredient is a protocol that tests the inclusion of an element […]
Optimal Client-Server Assignment for Internet Distributed Systems
We investigate an underlying mathematical model and algorithms for optimizing the performance of a class of distributed systems over the Internet. Such a system consists of a large number of clients who communicate with each other indirectly via a number of intermediate servers. Optimizing the overall performance of such a system then can be formulated […]
Authorization Security model conceived to secure access to Semantic repositories
Most semantic repositories are designed to manage semantic models but do not deal with access rights. As in the case of databases that are traditional, data stored inside a semantic database should be protected. by granting access to authorized users only. Semantic models help in achieving semantic interoperability among sources of data and applications. The […]
