基于位置隐私保护的手机应急报警系统研究与设计

Research and Design of Mobile Phone Emergency Alarm System Based on Location Privacy Protection

智能手机已经成为人们日常生活的必需品,且随身携带。手机可以作为保护用户人身安全的重要工具,通过监测用户手机的状态数据,分析异常数据,及时地通知用户的紧急联系人来确保用户的人身安全。同时,为确保在监测和发送用户数据时用户的位置隐私不被泄露,利用优化伪数据集的划分策略,提出一种基于k-匿名位置隐私保护策略来保护用户的位置隐私数据。开发的一款测试App,通过运行,可以安全有效地保护用户的安全。

Smart phones have become a necessity in people’s daily life and they are carried with them.The mobile phone can be used as an important tool to protect the user’s personal safety,by monitoring the user’s mobile phone status data,analyzing abnormal data,and promptly notifying the user’s emergency contacts to ensure the user’s personal safety.At the same time,in order to ensure that the user’s location privacy is not leaked when monitoring and sending user data,the division strategy of optimizing the pseudo-data set is used to propose a k-anonymous location privacy protection strategy to protect the user’s location privacy data.Finally,a test APP was developed,which can safely and effectively protect the safety of users by running.
