Data Integrity Checking Protocol with Data Dynamics and Public Verifiability for Secure Cloud Computing

Abstract – In the concept of cloud computing the main actor is Third Party Auditor. In this paper we propose method to eliminate the Third Party Auditor from cloud computing which mainly checks whether the user which is using the cloud services is authorized or not. Here we will try to come up with new service which is capable removing the most of threats occur in the normal working of cloud computing. In contrast to conventional solutions, which are well protected by standardized data access procedures, organizations tend to lose integrity of data when the systems are outsourced to cloud. Since the data is stored they must ensure to overcome threats occurring in the cloud. Our proposed system includes the new concept of dynamic encryption. In dynamic encryption the encryption algorithm type is decided dynamically depending upon the type of data as well as the size of data
