Abstract:
1. A non-transitory computer-readable storage medium encoded with code segments for regenerating a destroyed seed, the computer-readable storage medium comprising: a comparison segment for comparing a live biometric template with an enrolled biometric template; an interval-determining segment for determining a testing interval based upon a probability that the live biometric template and the enrolled biometric template are indicative of a specific user, and based upon an optimization value associated with the enrolled biometric template, wherein the testing interval has a plurality of values therein, wherein one of the plurality of values is indicative of or is the same as said destroyed seed; an interval-filtering segment for applying a filter to the plurality of values within the testing interval so as to reduce noise within the testing interval, such that after application of the filter, the testing interval is a filtered testing interval, wherein subsequent to applying the filter, the one of the plurality of values indicative of or the same as the destroyed seed remains in the filtered interval; and a testing segment for iteratively testing the plurality of values within the filtered testing interval to determine a decrypting value, wherein the testing comprises decrypting an encrypted item of test data, wherein upon testing a particular value within the filtered testing interval and determining that the particular value is operable to decrypt the encrypted item of test data, the destroyed seed is regenerated and the testing segment ceases iteratively testing, wherein said interval-filtering segment is executed subsequent to said interval determining segment but prior to iteratively testing the values within the filtered testing interval.
