Embodiment Construction

[0063] For many applications, user authentication is an important and fundamental component. Automated biometrics can provide precise and undeniable verification methods. In the digital world, the same advantages come with several serious disadvantages. Digital representations of biometric signals can be used in many applications where the owner is unknown. Second, the signal can easily be transmitted to law enforcement agencies, thereby violating the user's privacy. The present invention provides a method to overcome these problems by employing a triangle-based transformation of the fingerprint representation to intentionally distort the original fingerprint representation so that two devices do not share the same resulting fingerprint representation.

[0064] The present invention describes revocable fingerprint representations (a specific example of revocable biometric representations), also referred to herein as "anonymous biometrics." Unlike regular biometric represent...

Abstract

There is provided an apparatus, method, and program storage device for representing biometrics. The apparatus includes a biometric feature extractor and a transformer. The biometric feature extractor is for extracting features corresponding to a biometric depicted in an image, and for defining one or more sets of one or more geometric shapes by one or more of the features. Each of the one or more geometric shapes has one or more geometric features that is invariant with respect to a first set of transforms applied to at least a portion of the image. The transformer is for applying the first set of transforms to the at least a portion of the image to obtain one or more feature representations that include one or more of the one or more geometric features, and for applying a second set of transforms to the one or more feature representations to obtain one or more transformed feature representations.

Description

technical field [0001] The present invention generally relates to the field of image processing. More specifically, the present invention relates to a machine representation of fingerprints based on the geometrically and photometrically invariant properties of triangular images. Furthermore, the present invention relates to intentionally distorting a machine representation of a triangle-based fingerprint, and then using this distorted representation in a secure and privacy-preserving transaction. Background technique [0002] Biometrics are physical or behavioral characteristics of a person that can be used to determine or verify an individual's identity. Biometrics such as fingerprints have been used by law enforcement agencies to identify criminals for a decade. More recently other biometrics such as face, iris and signature have begun to be used to identify people in many types of transactions such as check cashing and ATM use. An automatic biometric identification sys...
