Abstract

Access control systems and methods regulate access to shared content items in a corpus using visibility tokens. A user provides other users with access to a content item by associating a content token with the content item and associating a matching user token with each user who is to be granted access. A user who attempts to access the content item succeeds only if that user has a user token matching the content token associated with the content item. User tokens can be propagated automatically from one user to another, e.g., based on trust relationships among the users. Content tokens can be indexed with content items so that when a user searches the corpus, a search engine can detect matches between user tokens and content tokens and filter the search results based on whether they are visible to the querying user.
