1. A method for storing biometric information on a token comprising a magnetic storage medium, the method comprising:
- capturing a biometric image and generating therefrom digital pixel data for an array of image pixels;
selecting a plurality of spaced apart sets of image pixels from the array of image pixels;
processing respective sets of digital pixel data for the selected spaced apart sets of image pixels to produce biometric data; and
storing the biometric data on the magnetic storage medium of the token.

Abstract
The system and method store biometric information on a token having a magnetic storage medium. A biometric image is captured and digital pixel data is generated therefrom for an array of image pixels. A plurality of spaced apart sets of image pixels are selected from the array of image pixels, and respective sets of digital pixel data are processed for the selected spaced apart sets of image pixels to produce biometric data. The biometric data is stored on the magnetic storage medium of the token for subsequent use in verifying an authorized user of the token.

10. A method of regulating the use of a token, the token comprising a magnetic storage medium having biometric data of an authorized token user stored thereon, the biometric data comprising selected spaced apart sets of image pixels from an array of image pixels of an enrollment biometric image, the method comprising:
-
capturing a verification biometric image and generating digital pixel data for an array of image pixels from the verification biometric image;
decoding the biometric data stored on the magnetic storage medium of the token; and
comparing the spaced apart sets of image pixels from the decoded biometric data with the digital pixel data for the array of image pixels from the verification biometric image to determine if the token holder is the authorized token user. - View Dependent Claims (11, 12, 13, 14, 16, 17, 18, 19, 20)

15. A method of regulating the use of a token, the token comprising at least one of an access card, credit card, debit card, identification card and smart card, and including at least a magnetic storage medium thereon, the method comprising:
-
enrolling an authorized token user by capturing a first biometric image and generating therefrom first digital pixel data for a first array of image pixels, selecting a first plurality of spaced apart sets of image pixels from the first array of image pixels, processing respective sets of digital pixel data for the first plurality of selected spaced apart sets of image pixels to produce enrollment biometric data, and storing the enrollment biometric data on the magnetic storage medium of the token; and
verifying an identity of a token holderpresenting the token by capturing a second biometric image and generating therefrom second digital pixel data for a second array of image pixels, and comparing the second digital pixel data with the first plurality of selected spaced apart sets of image pixels of the enrollment biometric data stored on the magnetic storage medium of the token to determine if the token holder is the authorized token user.

21. A system for regulating the use of a token, the token comprising at least one of an access card, credit card, debit card, frequent flyer card, driver'"'"'s license card, identification card and smart card, and including at least a magnetic storage medium thereon, the system comprising:
-
an authorized token user enrollment unit including a first biometric sensor device for capturing a first biometric image and generating therefrom first digital pixel data for a first array of image pixels, a first image processor for selecting a first plurality of spaced apart sets of image pixels from the first array of image pixels, and processing respective sets of digital pixel data for the first plurality of selected spaced apart sets of image pixels to produce enrollment biometric data, and a first magnetic storage medium reader/writer for writing the enrollment biometric data on the magnetic storage medium of the token;
at least one token holder verification unit for verifying the identity of a token holder presenting the token, and comprising a second biometric sensor device for capturing a second biometric image and generating therefrom second digital pixel data for a second array of image pixels, a second magnetic storage medium reader for reading the enrollment biometric data from the magnetic storage medium of the token, and a comparator for comparing the second digital pixel data with the first plurality of selected spaced apart sets of image pixels of the enrollment biometric data stored on the magnetic storage medium of the token to determine if the token holder is the authorized token user. - View Dependent Claims (22, 23, 24, 25, 26, 27, 28, 30, 31, 32, 33, 34, 35)
