Secure computation over cloud using fully homomorphic encryption

Computing by a cloud service has not succeeded much due to concerns about confidentiality and privacy assurances by the service providers. This challenge can be addressed if computations can be performed on encrypted data directly. In this paper, we have developed a scheme based on fully homomorphic encryption that can perform operations directly on encrypted images. Our aim is to take the first step towards solving the problem of those which are in dire need of computing services by a third party, namely cloud, without any security breaches. We believe this will be a major breakthrough in which security has been handled while computing.
