Dynamic seed and key generation from biometric indicia
First Claim
1. A system for regenerating a destroyed seed comprising:
- at least one processor; and
at least one non-transitory computer readable storage medium having a computer program stored thereon, said computer program including;
an initialization module that when executed by the at least one processor performs the steps of;
enroll a biometric template from a user to obtain an enrolled biometric template, andassign an optimization value to the enrolled biometric template, said optimization value indicative of at least one feature of the enrolled biometric template;
a seed generation module that when executed by the at least one processor performs the steps of;
encrypt an item of test data using the optimization value to obtain an encrypted seed, anddestroy the optimization value and any associated unencrypted seed;
a live capture module that when executed by the at least one processor performs the steps of;
receive a live biometric template provided by the user, andcompare the live biometric template with the enrolled biometric template; and
a seed regeneration module that when executed by the at least one processor performs the steps of;
determine a testing interval comprising a plurality of values; and
test at least a portion of the plurality of values within the testing interval to determine a decrypting value for the encrypted seed,said testing further including using each tested value to attempt to decrypt the encrypted seed,wherein upon a tested value successfully decrypting the encrypted seed, the destroyed seed is regenerated.

Abstract
Generating a seed and/or a key from live biometric indicia, such that all the information necessary for generating the seed and/or the key is not stored, is provided. A method comprises receiving and enrolling a biometric template from a user; assigning an optimization value to the enrolled biometric template; encrypting an item of test data using the optimization value, such that the optimization value is an encryption seed; storing the encrypted item of test data on the storage medium; destroying the encryption seed after encrypting the item of test data; receiving a live biometric template; comparing the templates and determining an interval based on a probability that the templates are specific to the same user; iteratively testing values within the interval to identify the value in the interval for decrypting the encrypted item of test data; and generating the key using the seed.
