Host based content security and protection

Host based content security and protection. Security is achieved via a third-party device serving as an intermediary or host (e.g., certificate authority (CA)) between two or more user device is associated with two or more users. Any number of security measures may be employed to ensure that the content and/or identity associated with a given user is protected, including on a per communication or content basis. Various authentication, authorization, and accounting (AAA) protocols may be employed to govern the respective sharing of content and/or identity between respective users within the system, and such AAA protocols may be dynamically allocated differently with respect to different pairings of users at different respective times. In addition, with respect to digital rights management (DRM) employed to govern the security of content and/or identity between users, a third-party device (e.g., intermediary) and/or any respective user may establish specific rules for secure content and/or identity communications.
