一个普适计算环境中的定位隐私保护模型

Location privacy protect model for pervasive computing

随着普适计算技术的发展,在普适环境中的应用服务也日益增多。这些服务通常都是基于用户位置的服务,然而,用户的定位信息中往往直接或间接地包含着用户的隐私内容。针对如何在获取个性化定制服务的同时保护用户的定位隐私这一问题展开讨论,提出了一种定位信息采集和假名使用的策略,并基于该策略建立了一个普适计算环境中的定位隐私保护模型。

With the development of pervasive computing technologies, the applications in ubicom environment was increasing. Those application usually based on user＇ s location information, which included user＇ s privacy information directly or indirectly. This paper discussed how to protect user＇ s location privacy while personalized service was provided. Proposed user＇ s location information acquisition policy and pseudonym policy and built a model for protect user policy of pervasive computing based on those policy.
