1. A tokenless method for rapid search of previously stored biometric samples from individuals using at least two biometric baskets, at least one biometric basket containing at least two algorithmically unique biometric samples from different individuals, each biometric basket containing less than the total number of samples registered with the system, and each biometric basket being identified by a personal identification code, the method comprising;

  • a. a storage step further comprising;

    i. gathering a biometric sample from an individual;

    ii. selecting a personal identification code that indexes a biometric basket;

    iii. locating the biometric basket identified by the personal identification code;

    iv. comparing the biometric sample gathered from said individual, with all previously stored biometric samples in the biometric basket, to make sure that the biometric sample gathered from the individual is algorithmically unique from all biometric samples currently stored in said biometric basket for producing a successful or failed uniqueness result; and

    v. upon return of a successful uniqueness result, storing of the entered biometric sample gathered from said individual in the selected biometric basket; and

    b. a bid step further comprising;

    i. entering a bid personal identification code by a candidate individual;

    ii. entering a bid biometric sample by said candidate individual; and

    c. a comparison step further comprising;

    i. locating the biometric basket that is identified by the bid personal identification code entered by said candidate individual; and

    ii. comparison of the bid biometric sample from said candidate individual with all of the biometric samples stored in the identified biometric basket for producing either a successful or failed identification result.
