为了解决室内定位中用户和服务器双方的隐私保护问题,提出了一种在使用 Paillier 加密的过程中将部分计算外包给云服务器的方案,这不仅保护了用户和定位服务器的隐私,而且避免了产生过大的计算和通信开销.该方案的主要思想是服务器先在离线阶段建立指纹数据库,在线阶段用户将k匿名算法和Paillier加密结合,将加密后的Wi-Fi指纹发送给定位服务器,服务器对接收到的Wi-Fi指纹和数据库指纹进行聚合处理,然后外包给云服务器进行解密和距离计算,最终得到定位结果.理论分析和实验结果表明了所提方案的安全性、有效性和实用性.
Privacy-preserving indoor localization scheme based on Wi-Fi fingerprint with outsourced computing
To solve the privacy-preserving problem of both the user and the server in indoor positioning,outsourcing part of the calculation to cloud server in the process of using Paillier encryption was considered.The scheme not only pro-tected the privacy of the user and the positioning server,but also avoided excessive computing and communication over-head.The main idea of the scheme was that the fingerprint database in the offline stage was established by the server firstly.The k-anonymity algorithm was combined with Paillier encryption in the online stage by the user,and the en-crypted Wi-Fi fingerprints were sent to the positioning server.An aggregation of the received Wi-Fi fingerprints and da-tabase fingerprints were performed by the server.Then they were outsourced to the cloud server for decryption and dis-tance calculation by the positioning server.Finally,the positioning result was obtained.Theoretical analysis and experi-mental results show that the proposed scheme is safe,effective and practical.
