Abstract
Methods and systems for securing biometric templates and generating secret keys are provided. One or more images are received. Interest points are identified based on the received images, and a plurality of obfuscating data points are generated based on the interest points. An obfuscated template based on the interest points and the obfuscating data points is created and stored. A secret key can be encoded using a subset of at least one of the obfuscating data points and the interest points in the template.
Claims28
A computer-implemented method comprising:
- receiving one or more images;
- identifying a plurality of interest points based on the received images wherein each interest point is located in a respective tile of a plurality of neighboring tiles;
- generating a plurality of obfuscating data points based on the interest points, wherein the obfuscating data points are generated such that a spatial distribution of the interest points and a spatial distribution of the obfuscating data points are substantially similar within each of tiles;
- creating an obfuscated template based on the interest points and the obfuscating data points;
- and
- storing the obfuscated template.
