In recent few years the new type of mobile marketing term as mobile location based services has attracted strong attention.

In this system mobile user can gather area based tokens from the token wholesalers, and then exchange their collected tokens at token collectors for beneficial rewards. Here, we develop a security and privacy aware location based rewarding protocol for the SLBRDS system, Furthermore, we also show that the proposed system is capable to flexible different attacks and versatile client security can be well protected.
