Relational Anonymous Credentials are here!

CASCAde proposed a new form of anonymous credentials that enables users to gain access to resources based on their social graph. In a world in which Online Social Networks and relational authorization is prevalent, e.g., you can access my photos if you are a friend of a friend, the new technique offers a privacy-preserving alternative. The so called relational anonymous credential scheme (ReACS) encapsulates the social graph of a user and enables the user to prove to others that they are related, without disclosing further information in the process.

The concept of the relational anonymous credentials is released as preprint output.
