A NOVEL STUDY FOR MANAGING PRIVACY OF DATA AND USER IN ACCESS CONTROL METHODS

M. Subhashini, N. Sujatha

Abstract


Different methods were proposed to defend data contents confidentiality by means of access control. We need to attain a multi-authority cipher text based encryption which achieves security; assurance privacy of data consumer identity information; as well as tolerating compromise attacks on authorities hence we propose a framework to permit cloud servers to manage user access privileges without finding of their identity data. While people are more worried regarding their identity privacy, it moreover needs to be protected prior to cloud entering our life.  Any of the authority or else server alone should not make out any client’s personal data.  It decentralizes central authority to confine identity leakage and as a result gets semi-anonymity and generalizes file access control to privilege control, by which privileges of the entire operations on cloud data are managed within an efficient way. The proposed framework not only data privacy, but also user identity privacy within existing access control methods.
