Today location based services are becoming more popular. Majority of the applications are based on user's current location. So there may be some malicious users rely on that application. The malicious can access our location. In this paper we propose a Spatial Temporal Provenance Assurance with Mutual Proofs (STAMP). It is used for ad-hoc mobile users generating location proofs in distributed settings. It is accommodating wireless access points and trusted mobile users. It ensures integrity and

... non-transferability as well as protecting user's privacy. A semi trusted CA is used for cryptographic key distribution as well as guard uses against collusion by a light-entropy based trust model. It's implementation on IoS platform shows that it requires low cost in terms of computational and storage resources.
