Installed base of the IMS (Userbase)


Interoperability and supported standards

OpenPrivacy as a framework does not incorporarte specific standards, although projects like Freenet, Free Haven or Publius explicitly will fit in well.

Server-side component(s)

Reputation Services base on Nym-Server, which are currently used as anonymous remailer. Reputation is appended to a nym and stored. This “opinion store” can be addressed from other repuation servers.

Client-side component(s)

Reputations are stored on reputation-servers, so private keys to the parent nym is the only data stored locally.

Description of functionality / features (client and server)

OpenPrivacy uses the nym-concept to establish a network of unlinkable pseudonyms. Apart from this the framework does not imply cryptographic standards.
