Enhancing Security in Cloud Computing for Third Party Auditor by Self-destruction Mechanism

Abstract

The main aim study in cloud computing system, large amount of data can be maintained in the cloud storage system and it can be used for application based services for client. The bulk amount of data privacy will not be properly maintained by the cloud service provider. Without knowledge of authorized client, data can be viewed by another user with the permission of Cloud Service Provider (CSP). Many cryptography technique can be used for data privacy in the TPA (Third Party Auditor) which is the trusted authority to audit and verify the integrity in cloud. The cloud loaded data can be viewed by authorized user and copy of data can be in tag based data placed in TPA and data privacy can be affected in TPA system. In the proposed system, data privacy can be maintained in the TPA view by using self destruction mechanism to destroy the data after the view point of data for particular time and then the viewed data copy can be destruction in TPA. The cloud service provider can be securely loading the data in cloud via TPA Server. The main advantage of the self destruction mechanism security for the data in cloud via TPA server without the permission of the particular authenticated client other user cannot viewed the individual client data. Then data privacy can be perfectly maintained in the cloud service.
