论文摘要
使用在线社交网络时，用户经常与不同的社交群体共享信息。当考虑组的背景时，成员内通常没有或很少的交集。这意味着共享信息的用户通常必须与所有组的所有成员共享。用户无法确定哪个组看到哪些信息可能是有问题的。因此，我们的方法允许用户决定可以访问它的所有信息。此外，可以创建受保护的圆圈，用户可以在其中共享信息。共享信息和圆圈已加密，可以通过代理分发键。
When using Online Social Networks, users often share information with different social groups. When considering the backgrounds of the groups there is often no or little intersection within the members. This means that a user who shares information often has to share it with all members of all groups. It can be problematic that the user cannot decide which group sees which information. Our approach therefore, allows users to decide for every bit of information who can access it. Further, protected circles can be created, where users can share information within. Shared information and circles are encrypted and the keys can be distributed by proxies.
