One-Way Fingerprints Demo 1 of 4

Problem
Counterfeit bank checks are:

  • cashed by banks and other    check payers.
  • accepted as payment for    goods and services.
  • accepted for deposit by    banks.

  • Solution

    Provide Free web-based authentication so that:

  • a bank check's information    can be authenticated before    cashing or accepting as    payment or for deposit.
  • counterfeiters cannot produce    a bank check with the correct    information without access to    the actual check.

  • Benefits

    Eliminate losses from counterfeit bank checks by detecting:

  • counterfeit bank check    numbers before cashing or    accepting as payment or for    deposit.
  • Authentication
    This demo will show how Ethent's PINs using One-Way Fingerprints system uses a check issuer selected PIN to authenticate a bank check number - even though Ethent doesn't know the bank check's PIN.

    PIN
    A PIN is a Personal Identification Number selected by the check issuer for each issued bank check. A randomly selected PIN provides each bank check with an unpredictable number - counterfeiters cannot determine a bank check's PIN without access to the bank check.

    One-Way Fingerprints Authentication
    In this demo a one-way fingerprint of a bank check's PIN is calculated and this fingerprint is used to authenticate the PIN and check number printed on a bank check.

    Fingerprint
    A Fingerprint of a bank check's PIN is a unique mathematical representation of the bank check's PIN.

    One-Way
    A bank check's fingerprint is One-Way if the bank check's PIN cannot be calculated from its fingerprint.

    Example
    For example, If a bank check's PIN is 2693 and its fingerprint is "7b96a39j6nh72g8ael184jy5nq4c832b9omff56r", then this fingerprint is one-way if the 2693 cannot be calculated from this fingerprint.

    See Ethent Notes: "One-Way Fingerprints" for a more complete discussion.


    Calculate One-Way Fingerprints
    For this demo these bank and account numbers are assumed:
    Bank Number: 1234
    Account Number: 5678

    Provide a real or imaginary Check Number and a four digit PIN for a bank check - then click Submit.
