Biometric Authentication for Cloud Service Provider in Multiple Cloud Storage System

Abstract

Cloud storage services provides users to store large amount of files. Distributed
clients can also access the file storage. To provide integrity, controllable outsourcing and
auditing on outsourced file, we used a scheme called identity-based data outsourcing
(IBDO) which provide more advantageous when compared to existing systems. In IBDO
scheme, the users allows the designated entities to upload data on behalf of the user. The
entities are authorized and identified using their identities. The IBDO also promotes
comprehensive auditing which allows the user to check the information based on type and
consistence of outsourced files and also the MAC address and IP address are checked. To
provide more security we added biometric authentication called fingerprint analysis and to
overcome security threats, we proposes multiple cloud storage system using split and
merge technique, e.g., a file is divided into multiple fragments and stored in multiple
clouds.
