Friend discovery based on common attributes or similarity of users' profile is a key component of mobile social networking. Preserving the privacy of profiles of matching users whiles matchmaking is the major challenge of this system. These profiles contain very sensitive information such as interests, political tendency and health conditions. Matchmaking protocols have been based on the assumption that users of the system must agree to some compromise with group managers, setup procedures and revocation procedures. It is however disturbing that these users desire systems with no trusted third parties and a complete unconditionally user ambiguity.
