Anonymity and Privacy Security Scheme on Location Based Services

摘要: Anonymity and privacy are two security services frequently confused when schemes designed. On the one hand, refers to transform information in order keep it from all but those who authorized have it. other anonymity a condition which receiver does not know sender’s identity. From Location Based Service (LBS) point of view, very important preserve, as sensitive data travel service request, for example identity participants their location. Most related work focuses on protecting only aspect LBS user letting secure aspect. this paper we present scheme that consists set cryptographic protocols consider primitives along with fake location information, provide both privacy. The importance relies fact proposed remains transparent provider. Moreover, results obtained show approach focused removing trust provider, did represent an excessive increment cost usage channel makes our suitable interesting improvement over previous works.
