The wide use of mobile social networks has made it easier for people to share and exchange information with others anywhere, anytime.However, sharing operations of personal data on mobile social networks has put individual privacy under risk in unprecedented ways.We propose a protocol for privacy-preserving P2P information sharing for mobile social networking; because of the limitation of computation and communication for mobile devices, traditional privacy-preserving information sharing for private data sources cannot be applied in mobile social networks.Therefore, we designed a lightweight obfuscation and encryption model to defend against honest-but-curious behavior attack.The protocol is practical for mobile devices and the simulation performance is encouraging.
