基于联合熵隐私保护的自适应动态Mix-zone方案
Dynamic Mix-zone scheme with joint-entropy based metric for privacy-perserving in IoV
摘要
Abstract
Aiming at the weak flexibility and lack of users' transparency existing in the current Mix-zone schemes for In-ternet of vehicle (IoV), a dynamic was proposed for Mix-zone construction with traffic adaption, which could construct a Mix-zone for the vehicles dynamically according to the traffic conditions for changing pseudonym at anytime and anywhere. This kind of Mix-zone could achieve privacy-preserving based on the identity and location. In addition, a novel traf-fic-adaptive metric was presented for classifying the privacy leveled in Mix-zone, which applied the normalization quantita-tion to measure the degree of Mix-zone's privacy demanding by the current region. It was verified that the joint entro-py-based privacy measuring model and the Mix-zone construction scheme by utilizing the trajectory data of taxis in certain district in Shenzhen city. The experimental shows that the proposed combination entropy-based model could depict the pro-portional relationship between the traffic scene parameters and the privacy-preserving degrees. The scheme is better in per-formance over the related methods, and strikes a good balance between location privacy and service usability.关键词
