An Approach for Distributed Data Possession in Multi-Cloud using SelCSP

The important concept in the cloud storage is checking integrity in the remote data. It can provide the user with verification of the outsourced user files without downloading the complete data. There are some situations in which user needs their files to be kept on multiple cloud servers, so as to provide security and better prediction of cloud servers. The ID-DPDP (identity-based distributed provable data possession) enhance model for checking remote data integrity in multiple clouds. The proposed model can provide various levels of verifications. The ECC (Elliptic Curve Cryptography) algorithm is used for generating keys and symmetric encryption algorithm for encryption of data and the corrupted files concept is introduced in our system also for enhancing the security of the system use the SelCSP (Select Cloud Service Provider) is done. Which will check the authenticity of cloud service provider will also collect the user feedbacks on various cloud service providers weather the cloud service provider is malicious or trustworthy
