The Profile identical means two users comparing their individual profile and is frequently the first step towards effectual PMSN. It, however, conflicts with the users’ growing isolation concerns about disclosing their individual profiles to complete strangers before deciding to relate with them Our protocols make possible two users to carry out outline similar without disclosing any data about their accounts/profiles ahead of the judgment result. Making new associations according to personal preference is a essential service in mobile social networking, where an initiate user can find matching users within physical propinquity of him/her. In an existing systems for those services, frequently all the clients directly publish their full profiles for remaining of them to search. Though, in much submission, the users’ personal outline may contain sensitive in order that those do not want to create it open thing. In this paper, we explored a set of privacypreserving profile identical themes for mobile social networks which are based on proximity. In an initiate client can discover from a set of clients the one whose profile/account greatest counterpart with her / his; to restrict the danger of secure disclosure, only required and least information about the confidential characteristic of the partake users is exchanged. Two the increasing levels of user solitude are distinct, with falling amounts of exposed profile/account data. Leveraging secured/protected multiparty computation (SMC) method we propose novel modus operandi that understand each of the client privacy levels, which can also be adapted by the users. We bring in formal security proofs and presentation evaluation on our system, and show their compensation in both security and good organization over stateoftheart methods. The social familiarity between two clients/users as the identical metric, which can measure the distance between their social coordinate with each being a vector pre calculated by a central server which is trusted to stand for the location of a client in an online social network. By judgment, our work does not rely on the link of PMSN clients with a one social network in online and talk to a more general classified identical crisis for PMSN by helping finegrained private profiles/account and a huge spectrum of corresponding metrics.
