【摘要】 移动平台的发展给用户带来了更多功能强大应用,而恶意应用也开始出现,一些恶意应用的目的在于泄漏用户的地理位置隐私。为了保护用户的地理位置隐私安全,提出一个模糊化地理位置信息的系统设计,由用户指定每个应用的地理位置信息精确度,系统截获应用的地理位置请求后加以模糊。基于Android开源移动平台实现一个原型系统。经过可用性测试,证明该系统的确可以保护用户的位置隐私。更多还原

【Abstract】 The development of the mobile platform has brought more applications with powerful functions,meanwhile the malicious applications also come up as well. Some of the malwares target at leaking the privacies of users geographical location. In order to protect the security of users privacy in geographical location,our research proposes a system design in regard to obfuscating the geographical location information. The accuracy of every applied geographical location information is specified by the user,the system obfuscates the applied geographical location request after it is intercepted. Based on Android open source mobile platform,the authors implement a prototype system,by usability testing,it is proved that the system does be able to protect users location privacy.更多还原
