Advanced privacy identity for location of smart phone users

摘要

Recent era is immensely concerned on the applications based on “SPATIAL TEMPORAL PROVENANCE (STP)” (i.e)users' check-in behaviors like, people visiting different places at different times of weekdays. Our system is based on providing location identity for mutual persons involving in a distributed transaction. It works under the principle of STAMP (Spatial-Temporal provenance Assurance with Mutual Proofs) scheme in an ad-hoc network that is applicable for the trusted mobile users and WAP(Wireless Access Points)on the android platform. The cryptographic keys are distributed and the users are protected from collusion between each other by a semi-trusted Certificate Authority. Hence in our proposed system, we have introduced a third party to create the STP identity whom both the user's trust derby creating a mutual proof. Providing authentication to the STP identity is done to achieve integrity and non-transferability, giving countermeasures against collusion. The scheme is efficient in terms of storage allocation and computation.
