Abstract
To reduce the latency introduced by network communications, the access rights to digital content of various users is locally cached, and such a local cache is referenced without incurring network communication latency. The local cache is predictive in that it can comprise users which a user editing the digital content is more likely to reference in the future, thereby triggering a determination as to whether such users have access rights to the digital content. The predictive aspects of the local cache are informed by a social graph delineating relationships between a user editing the digital content and other users. The social graph can be further refined based on metadata about the digital content, or based on the digital content itself. In addition to comprising users who have access rights to the digital content, the local cache can also comprise users that have been determined to not have access rights.
