A Proxy-Based Encrypted Online Social Network With Fine-Grained Access
share
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.
