Abstract

A mechanism is provided in a data processing system for image anonymization. The mechanism identifies a plurality of items in an image and extracts properties of the plurality of items into one or more data structures. The mechanism queries an analytics tool about whether a combination of properties of the plurality of items identifies a person in the image. Responsive to determining a given combination of properties of the plurality of items identifies a person in the image, the mechanism modifies the plurality of items in the image to form an anonymized image and outputs the anonymized image.

Claims

1. A method, in a data processing system, for image anonymization, the method comprising:

identifying a plurality of items in an image;

extracting properties of the plurality of items into one or more data structures;

querying an analytics tool about whether a combination of properties of the plurality of items identifies a person in the image;

responsive to determining a given combination of properties of the plurality of items identifies a person in the image, modifying the plurality of items in the image to form an anonymized image; and

outputting the anonymized image.

2. The method of claim 1, wherein identifying the plurality of items comprises performing image processing on the image.

3. The method of claim 1, wherein a given item within the plurality of items comprises a person and wherein properties of the given item comprise at least one of hair color, eye color, body type, height, clothing items, clothing color, or clothing style.

7. The method of claim 6, wherein identifying the plurality of combinations of properties comprises starting with single property sets and proceeding with gradually larger property sets.

8. The method of claim 1, wherein the analytics tool whether a given combination of properties of the plurality of items identifies a given person in the image based on a plurality of data sources.

9. The method of claim 8, wherein the plurality of data sources comprise at least one of whether data, demographic data, sales statistics, or user rights and roles.

10. The method of claim 1, wherein modifying the plurality of items in the image comprises replacing, obscuring, or obfuscating one or more items corresponding to the combination of properties.
