Stamp: Enabling Privacy Preserving Location Proofs for Mobile Users
Nowadays location based mostly services area unit quickly turning into common. several services that area unit supported user's location can even use the user's location history or their spatial temporal place of origin. It uses GPS technology. international Positioning System (GPS) could be a satellite based navigation system created of a network of various satellites. Malicious users could slug their spatial temporal place of origin while not a rigorously designed security system for users to prove their past locations. associate degree word form STAMP stands for abstraction Temporal place of origin Assurance with Mutual Proofs. essentially STAMP is meant for ad hoc mobile users generating location proofs for every different in a very distributed setting. thus it will simply accommodate trustworthy mobile users and wireless access points. STAMP ensures the integrity and non transferability of the situation proofs and protects user's privacy. A semi trusted certification Authority is employed to distribute cryptologic keys in addition as guard users against collusion by light weight entropy based mostly trust analysis approach. STAMP is affordable in terms of procedure and storage resources. This protocol is meant to maximise user's namelessness and site privacy. Here users area unit given the management over the situation graininess of their standard atmosphere proofs. STAMP is collusion resistant. associate degree entropy based trust model is projected to notice users reciprocally generating pretend proofs for every different.
