Efficient Query Integrity Management in Cloud with Grid Computing

"Efficient Query Integrity Management in Cloud backing with Grid Computing" which gives solution to integrity problem. In our system grid is used as back end for computing. It is also used for parallel joins or chain of joins. Powerful encryption technique i.e. salt encryption is used in this system. Use of markers preserves the integrity of query as computational server processes on encrypted data. System is secured with MD5 and AES encryption algorithms at various stages.In future we will extend these techniques on data which is stored in image format. Also we will extend this system for real time databases.
