Privacy Management in Cloud by Making Use of Homomorphic Functions
Cloud computing is new era, attracting peoples for different services providing in cost effective manner. Privacy management is one of the critical issues in cloud when these services accessed through untrusted service provider or third party. There is risk with sending personal information to such parties. The authors proposed a strong privacy preserving scheme for processing of personal information at untrusted service provider or third party end in the cloud. With making use of homomorphic encryption function on personal information, the proposed scheme maintains confidentiality of personal information sent by the cloud users to untrusted service provider or third party. While registering to a cloud, the personal information sent by cloud user is encrypted by making use of homomorphic function.
