Privacy manager for restricting correlation of meta-content having protected information based on privacy rules

摘要

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.

主权项

1. A method comprising:
intercepting, by a device comprising a processor, correlation instructions related to a plurality of meta-content elements associated with a primary content; selecting at least one meta-content element of the plurality of meta-content elements, the selected meta-content element having privacy protected information specified in privacy rules; determining a set of meta-content items of the selected meta-content element that are subject to a correlation restriction based on evaluation of the privacy rules with respect to meta-content items contained in the meta-content element; and enforcing the privacy rules for the set of meta-content items, wherein the enforcing the privacy rules comprises restricting co-occurrence of at least two meta-content items of the set of meta-content items, and wherein the restricting co-occurrence comprises: evaluating a threshold as one of a minimum value for temporal difference in occurrence of the at least two meta-content items, a difference in location of the at least two meta-content items, or a difference in context between the at least two meta-content items.
