PDP is a technique designed for CSP to show that complete file of the client is in secured state without downloading the whole file. PDP scheme of multi cloud includes multiple cspÃ¢â?¬â?¢s to mutually store and maintain the clientÃ¢â?¬â?¢s data. Later CPDP was proposed which also has the Homorphic verifiable response and Hash index hierarchy properties, but there is a security flaws. The problem is, when a malicious csp or organizer generates a valid response which also clears the verification process in case of deletion of the stored data. This means, simply, an attacker gets the information without storing the clientÃ¢â?¬â?¢s data. In this paper, we discuss about the security flaws in CPDP (Cooperative Provable Data Possession) scheme.
