Secure Audit Service by Using TPA for Data Integrity in Cloud System
Abstract— Secure Audit Service by Using TPA for Data Integrity in Cloud System. Cloud computing is the vast computing utility, where users can remotely store their data into the cloud so to have the benefit of the on-demand < Final Year Projects 2016 > availability of huge and different applications and services from a shared pool of configurable computing resources. Cloud-based outsourced storage space reduces the patron load of storage management. It also reduces the maintenance load of customer by providing a comparably low-cost, scalable, location-independent platform. This new model of data hosting service commence a new security challenges, which requires an independent auditing service which audit the data integrity of cloud. There are different existing auditing services available in cloud which audit data integrity remotely in static motion but these are not applicable whenever data is dynamically updated in cloud. Since it require efficient and secure dynamic auditing method for data owner. However in cloud, the clients no have direct physical possession of data. It shows client faces different formidable risk like missing or corruption of data. To keep away from the security and integrity risk of data, audit services are essential to ensure the integrity and availability of outsourced data and to achieve digital forensics and credibility on cloud computing.
