基于语义的位置服务隐私保护综述

Review of semantic-based privacy-preserving approaches in LBS

位置服务发展引起的隐私泄露问题已不容忽视。基于语义的位置隐私保护是位置隐私保护工作中的重要组成部分。首先总结了近年来基于语义的位置隐私保护研究工作,包括隐私保护设计中的关键因素、语义保护可行性、相关概念等;随后讨论了基于语义的位置隐私保护机制、语义相似度测量方法、隐私保护度量方法等;最后展望了基于语义的位置隐私保护未来的研究方向。

The development of location-based services （LBS） caused serious privacy concerns. Semantic-based privacy-preserving approaches is an important part of privacy protection in LBS. The recent work on location privacy protection based on semantics were summarized, including key factors in design of privacy protection, the feasibility of semantic protection, related concepts. Then semantic-based location privacy-preserving mechanisms, measure- ment methods of semantic similarity, evaluation index of privacy for semantic location privacy were discussed. Finally, some future research directions of semantic-based location privacy protection were prospected.
