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.
