中文摘要:确保互联网服务在满足用户功能性需求的前提下保护隐私信息,是隐私保护研究的关键问题。访问控制是保护信息的传统手段,但其缺少使用目的、信誉度、义务等隐私语义,并且需要针对不同的数据使用者定义不同的策略。针对策略冗余、策略冲突等问题,提出了支持目的与信誉度绑定的隐私保护框架。首先给出了对应的访问控制模型,其次分析了隐私偏好的冲突问题,提出了目的冲突检测算法以及偏好冲突检测算法,最后通过实验证明了算法的可行性。

Privacy Preference Specification Model for Supporting Purpose and Reputation
Abstract:It is the key issue of privacy protection to ensure that Internet services protect privacy information under the premise of meeting the functional requirements of users.Access control is a traditional way to protect information,but it lacks privacy semantics such as purpose,reputation,obligation,and needs to define different strategies for different data users.Aiming at policy redundancy and policy conflict,a privacy protection framework supporting purpose and reputation binding has been proposed.Firstly,the corresponding access control model has been given.Secondly,the conflict of privacy preference has been analyzed.Finally,the purpose conflict detection algorithm and privacy preference conflict detection algorithm have been proposed.
