摘要:

传统访问控制模型无法满足新兴的多媒体社交网络场景下的用户数量大、动态交互和内容共享等特点.为此,提出了一种基于用户主要社交关系属性,如用户类型、紧密度、内容分享深度和信任度等,面向多媒体社交网络的访问控制模型.通过自定义安全规则及其安全策略冲突消解,有效地解决了数字媒体访问使用和分享传播中的安全问题,适用于多媒体数字版权保护应用的实际需求.

关键词: 多媒体社交网络, 访问控制, 安全规则, 策略冲突

Abstract:

Traditional access control models are not suitable for an emerging scenario of Multimedia Social Networks (MSNs), in which there are a large number of users, dynamic interaction and content sharing. The paper proposes an access control model for MSNs, based on users' major social relationships, such as relationship type, compactness, content sharing depth and trust. By the self-defined security rules and their security policies conflict elimination, the model effectively solves the security problem of access control and sharing dissemination on digital media, and it would apply to digital right management applications.

Key words: multimedia social networks, access control, security rules, policy conflict
