To address privacy concerns current implementation allows access to log records that are indirectly identified by upload-tag values. We plan to propose a practical homomorphic encryption schemes that will allow encryption of log records in such a way that the logging cloud can execute some queries on the encrypted logs without breaching confidentiality or privacy. Anonymous network implement the anonymity of users and provide privacy. In this paper implement the anonymous of user by implementing anonymous tag generation. CryptDB is a system that provides practical and provable confidentiality in the face of these attacks for applications backed by databases. It works by executing queries over encrypted data using a collection of efficient aware encryption schemes.. It greatly reduces the communication overhead between a log monitor and the logging cloud needed to answer queries on logs.
