提出两种基于SNS好友关系的信息共享授权代理机制,解决SNS用户给好友或好友的好友共享外部受保护资源的问题。与传统授权代理不同,提出的授权代理机制采用SNS网络中所特有的关系网络,使用第三方用户的身份信息临时访问受保护资源。通过授权代理机制,用户可以在一种受控方式下与好友共享更多的信息;同时,也可以在社会网络关系的帮助下获取所需的信息或文档。
Two kinds of information sharing authorization mechanism based on SNS friends relationship are proposed to solve the problem of sharing external protected resources by friends of SNS users or friends. Different from the traditional authorized agent, the authoritative proxy mechanism proposed uses the special relation network in the SNS network and uses the identity information of the third party user to temporarily access the protected resources. Through an authorized proxy mechanism, users can share more information with friends in a controlled manner; at the same time, they can get the information or documents they need, with the help of social network relationships.
