The increasing spread of location-based services (LBSs) has led to a renewed research interest in the security of services. To ensure the credibility and availability of LBSs, there is a pressing requirement for addressing access control, authentication and privacy issues of LBSs in a synergistic way. In this paper, we propose an innovative location-based fine-grained access control mechanism for LBSs, enabling effective fine-grained access control, location-based authentication and privacy protection. Our proposed approach is based on the construction of a spatio-temporal predicate-based encryption by means of efficient secure integer comparison. Our experimental results not only validate the effectiveness of our scheme, but also demonstrate that the proposed integer comparison scheme performs better than previous bitwise comparison scheme.
