Cloud storage is a new business solution for remote backup outsourcing, as it offers an abstraction of infinite storage space for clients to host data backups in a pay-as you-go manner. However it is indispensable for cloud service providers (CSPs) to provide security techniques for managing their storage services. We tackle this issue by implementing the framework for multicloud storage in which the client's data is manipulated with fine grained policy based access control. In addition an efficient cooperative Provable data possession (CPDP) scheme is designed which offers an efficient verification on the integrity and availability of stored data. The proposed system includes addressing two security issues. First provide guarantees of access control in which only authorized parties can access the outsourced data. Second provides cooperative PDP scheme to support dynamic scalability on multiple storage servers. Extensive security and performance analysis show that the proposed schemes are highly efficient and provably secure.

Security and Authentication of individuals is necessary for our daily lives especially in ATMs.But the security provided with ATM systems has some backdoors. It has been improved by using biometric verification techniques like face recognition, fingerprints, voice and other traits, comparing these existing traits, there is still need for considerable computer vision.Iris recognition is a particular type of biometric system that can be used to reliably identify a person uniquely by analyzing the patterns found in the iris.In the proposed system a new approach--IBIO(Iris recognition based BIOmetric verification) is provided for ATM banking system.Initially Iris images are collected as datasets and maintained in agent memory. Then the Iris and pupil are detected from the image,removing noises. The features of the iris were encoded by convolving the normalized iris region with 2D Gabor filter. The Hamming distance was chosen as a matching metric, which gave the measure of how many bits disagreed between the templates of the iris.Experimental results shows that all the bank accounts can be accessed without using cards through this Iris recognition efficiently.
