A Survey: Privacy Preserving Encryption Technique In Cloud Storage

Cloud computing introduces a new framework to access data and resources over internet , it allow user to remotely store data and use high on demand services and applications from a shared pool of resources but in that case data is outsourced ,thus data is vulnerable to many online security threats . These problem demands a secure framework which provides security for that data Thus, enabling public auditability for cloud data storage security is of critical importance so that users can resort to an external audit party to check the integrity of outsourced data when needed. So for that purpose a Third Party Auditing system (TPA) which take care the auditing task of outsourced data to check data integrity and make it worry free. Also TPA should be efficient and to audit outsourced data without asking the duplicate copy of that data and also not put any extra burden on the cloud user. We propose an advanced auditing system which provides following features
