Abstract: Secret information needs security in a multi user environment. The users no longer have physical control of the outsourced data that provides the data integrity protection in cloud computing a complex task particularly for users with constrained computing resources. Encryption alone is not sufficient in many cases. In this paper we are providing security to data by using biometric secret image (finger print), secret key generation and image slicing techniques .The encrypted image is shared using image slicing so that the image need not be stored on the single server instead it is stored on multiple servers and assigning the secret keys by splitting key into multiple parts .secret key is necessary to reconstruct the encrypted image and used for the authentication purpose.
