Database outsourcing as a service is a new trend emerging in the computing industry instead of managing database in-house. This introduces several security issues related to database. One of the important security requirement is privacy. A Private Information Retrieval protocol (PIR) allows user to retrieve an element from the database in such way that identity of that element is not get revealed by database server. In this project work, we present the optimized lattice based PIR schema. This proposed schema is based on use of different techniques like General Purpose Graphics Processing Unit (GPGPU) and cache like technology to reduce accessibility. The latest proposed PIR scheme deal with user privacy, use of GPGPU but left to focus on data privacy, data confidentiality and accessibility cost. In our approach our system focusing on issues like user privacy, data confidentiality and accessibility cost by using cache and computational overhead by using GPGPU. Thus searching time of proposed PIR protocol is minimized to number of records in the cache. Thus our proposed design improves the overall performance of PIR protocol.
