Abstract: A method intercepts correlation instructions related to a plurality of meta-content elements associated with a primary content. The primary content or the meta-content elements may have associated privacy rules. At least one meta-content element of the group is selected as having privacy protected information specified in the privacy rules. A set of meta-content items, of meta-content element, are determined that are subject to a correlation restriction based on evaluation of the privacy rules with respect to each meta-content item contained in the meta-content element, and the privacy rules for the set of meta-content items are enforced.

Abstract: Authentication in a system includes presenting information to a user containing a partial sequence of a passcode along with distractors. The user is challenged to identify the partial sequence from among the information in order to gain access to the system.

Abstract: A disclosed content rights management system defines a content usage policy via a conditional rule set contained in metadata. The conditional rule set is correlated to at least one second content. An access control manager determines, dynamically, access rights conferrable to a user device or a server, based on the content usage policy and user history parameters. The embodiments may confer limited access rights for a first activity by a user device, or by a server, with respect to the protected content and the second content, and block a second activity with respect to the protected content and the second content, in response to determining that the request for the second content, in conjunction with the user history parameters, does not comply with the conditional rule set for the second activity.

Abstract: One disclosed method includes receiving correlation instructions related to a plurality of meta-content elements that are associated with a primary content. The primary content may be multimedia content such as, but not limited to, an audiovisual content. The method includes performing a correlation in response to receiving the instructions. The correlation is between the meta-content elements, where the meta-content elements each have an arbitrary granularity defining meta-content segments. The method returns a result based on the correlation. Another disclosed method include receiving a request having correlation instructions related to a plurality of meta-content elements, where the meta-content elements are associated with a primary content. Again, each meta-content element has an arbitrary granularity defining meta-content segments.
