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. 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.

Claims

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.

2. The method of claim 1, wherein the enforcing the privacy rules for the set of meta-content items further comprises:

enforcing the privacy rules by at least one of 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.

3. The method of claim 1, wherein the restricting co-occurrence further comprises:

preventing the at least two meta-content items from occurring in a correlation result based on the correlation instructions.

4. The method of claim 3, wherein the restricting co-occurrence further comprises:

preventing the at least two meta-content items from occurring in a single meta-content element produced as a portion of the correlation result based on the correlation instructions.

5. The method of claim 1, wherein the intercepting the correlation instructions comprises:

intercepting a request from a client application, the request including the correlation instructions.

6. The method of claim 1, wherein the restricting co-occurrence further comprises:

evaluating the threshold for co-occurrence of the at least two meta-content items, the threshold defined in the privacy rules, and performing the restricting co-occurrence based on the threshold.

7. The method of claim 2, wherein the enforcing the privacy rules by restricting access to a correlation result based on the correlation instructions further comprises:

deleting the correlation result.

8. The method of claim 2, wherein the enforcing the privacy rules further comprises:

initiating an alert based on a determination that the co-occurrence of the at least two meta-content items violates the privacy rules.

9. An apparatus, comprising:

at least one processor; and

memory, operatively coupled to the processor, containing executable instructions for execution by the at least one processor, wherein the at least one processor, upon executing the executable instructions is operable to perform operations comprising;

interception of correlation instructions related to a plurality of meta-content elements associated with a primary content;

selection of 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;

determination of 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 a meta-content item contained in the meta-content element; and

enforcement of the privacy rules for the set of meta-content items, wherein the enforcement of the privacy rules comprises restriction of co-occurrence of at least two meta-content items of the set of meta-content items, and wherein the restriction of co-occurrence comprises;

evaluation of a threshold of a minimum value for a difference in location of the at least two of the set of meta-content items, the threshold being defined in the privacy rules.

10. The apparatus of claim 9, wherein the operations further comprise:

enforcement of the privacy rules by at least one of prevention of execution of the correlation instructions, exclusion of the selected at least one meta-content element from a correlation based on the correlation instructions, exclusion of the set of meta-content items from a correlation based on the correlation instructions, or restriction of access to a correlation result based on the correlation instructions.

11. The apparatus of claim 10, wherein the operations further comprise:

enforcement of the privacy rules by restricting access to a correlation result based on the correlation instructions by deleting the correlation result.

12. The apparatus of claim 10, wherein the operations further comprise:

initiation of an alert when the co-occurrence of the at least two meta-content items violates the privacy rules.

13. The apparatus of claim 9, wherein the operations further comprise:

prevention of the at least two meta-content items from occurring in a correlation result based on the correlation instructions.

14. The apparatus of claim 13, wherein the operations further comprise:

prevention of the at least two meta-content items from occurring in a single meta-content element, wherein the single meta-content element is produced as a portion of the correlation result based on the correlation instructions.

15. The apparatus of claim 9, wherein the operations further comprise:

interception of the correlation instructions by intercepting a request from a client application, wherein the request includes the correlation instructions.
