【摘要】 智能设备的普遍应用离不开云计算的发展。随着越来越多的用户将个人隐私信息存放在智能设备终端,导致在移动设备丢失时可能造成的个人隐私泄露的问题。结合移动终端检测未授权用户的实际需求,设计了一种基于重认证的隐私保护方案。采用了于用户行为特征和情境感知的隐式重认证方法和基于属性的加密算法相结合的方式,从而有效地防止用户由于移动设备丢失而造成的信息泄露问题。更多还原

【Abstract】 The universal application of smart devices is inseparable from the development of cloud computing. As more and more users store their personal privacy information in smart device terminals, it leads to the problem of personal privacy disclosure that may be caused by the loss of mobile devices. According to the actual needs of mobile terminals to detect unauthorized users, a privacy protection scheme based on re-authentication is designed. The implicit re-authentication method based on user behavior characteristics and context awareness is combined with the attribute-based encryption algorithm, which can effectively prevent the information leakage caused by the loss of mobile devices.更多还原
