Efficient Query Integrity Management in Cloud backing with Grid Computing: An appraisal

Abstract

In cloud environment, queries are processed by

the computational servers over the externally stored databases.

There might be possibility of problem of data integrity. To

resolve this problem different protection techniques are used

(like salts, buckets, markers etc). But these protection techniques

are designed for single computational server. Existing system is

designed only for simple join query. It could not be applicable for

parallel joins or chain of joins. To reduce the overhead of single

computational server, system presented here gives distributed

environment at computational server using Grid computing. It

increases the performance of system.

In this system, client request is divided into subtasks at the

computational server who acts as manager. Then subtasks are

forwarded to number of workers among the grid environment.

The worker independently executes their tasks & result is given

back to manager. The system presented here, provides enhanced

security to data, as data is in encrypted form at computational

server.
