Abstract: Aimed at enhancing privacy protection of location-based services (LBS) in mobile Internet environment,an improved privacy scheme of high service quality on the basis of bilinear pairings theory and k-anonymity is proposed. In circular region of Euclidian distance, mobile terminal evenly generates some false locations, from which half optimal false locations are screened out according to position entropy, location and mapping background information. The anonymity obtains the effective guarantee, so as to realize privacy protection. Through security analyses, the scheme is proved not only to be able to realize such security features as privacy, anonymity and non-forgeability, but also able to resist query tracing attack. And the result of simulation shows that this scheme not only has better evenness in selecting false locations, but also improves efficiency in generating and selecting false nodes.
