面向数据提供者的隐私保护访问控制模型

摘要

With the rapid development and wide application of network and information technology,people can carry out their bus-iness virtually at any time in any place,which brings convenience to people and also increases the hidden troubles of sensitive data leak-age during their activities.In this paper,a provider-oriented access control (POAC) model for privacy preserving is established based on RBAC model,in which the data providers are allowed to define personalized access control policies according to their preferences. The results show that the proposed model can effectively solve the troubles of data providers�privacy data leakage and satisfy their personal-ized privacy preserving requirements.%随着网络和信息技术的快速发展及广泛应用，随时随地进行的网上虚拟活动在带来便利的同时也增加了敏感数据泄露的隐患。在基于角色的访问控制（ RBAC）模型的基础上，提出了面向数据提供者的访问控制（ POAC）模型。模型支持数据提供者根据自身的隐私偏好定义个性化的访问控制策略，有效地解决了数据提供者敏感数据的泄漏问题，满足了数据提供者的个性化隐私保护需求。
