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. The privacy rule enforcement may involve preventing execution of the correlation instructions, excluding the selected at least one meta-content element from a correlation based on the correlation instructions, excluding the set of meta-content items from a correlation based on the correlation instructions, or restricting access to a correlation result based on the correlation instructions.

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.

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.
