We provide an overview of privacy preserving association rule mining, which is one of the most popular pattern-discovery methods in the new and rapidly emerging research area of privacy preserving data mining. Various proposals and algorithms have been designed for it in recent years. In this paper, we summarize them and survey current existing techniques, and analyze their advantage and disadvantage...
With the development of Internet and Intranet, Web and distributed databases have been used more and more widely. It is important to properly handle network and Web database security issues including authentication, denial of service, and fine-grained access control. When database access control and the network security are addressed separately, the security systems are not optimized sufficiently...
Analyzed the energy consumption disciplinarian of the nodes in WSN, the node's energy attenuation forecast model (EAFM) can be established. A difference-threshold reporting mechanism (DTRM) is used to report the residual energy of nodes. The energy collection mechanism based on EAFM and DTRM can reduce energy data reporting times significantly, improve the efficient of energy data collection, save...
