Improving Privacy and Security of User Data in Location Based Services

Location Based Services (LBS) expose user data to malicious attacks. Approaches, evolved, so far, for preserving privacy and security, suffer from one or more anomalies, and hence the problem of securing LBS data is far from being resolved. In particular, accuracy of results vs. privacy degree, privacy vs. performance, and trust between users are open problems. In this article, we present a novel approach by integration of peer-to-peer (P2P) with the caching technique and dummies from real queries. Our approach increases efficiency, leads to improved performance, and provides solutions to many problems that have existed in the past. In addition, we offer an improved way of managing cache. Simulation demonstrates superiority of our approach over earlier ones dealing with both the ratio of privacy and that of performance.

An Integrated Architectural Clock Implemented Memory Design for Embedded System

Recently Low power custom memory design is the major issue for embedded designer. Micro wind and Xilinx simulator performs efficient cache simulation and high performances with low power consumption. SRAM efficiency analyzed with 6-T architecture design and analyzed the simulation performance for specific application. We have implemented clock based memory architecture design and analyzed internal clock efficiency for SRAM. Architectural clock implemented memory design that reduces access time and propagation delay time for embedded devices. Internal semiconductor material improvement increases simulation performance and these design implemented for application specific design architecture.
