  • Method of conducting anti-fraud electronic bank security transactions having price-date-time variables and calculating apparatus thereof
    Patent number: 6678666
    Abstract: A method of computing and verifying an authorization code for a transaction. The method includes creating an algebraic formula and storing the formula in a validation unit and a calculating apparatus. A calculation is made by entering values for variables of the formula into the calculating apparatus, which substitutes the values for the variables into the algebraic formula to calculate a value for an authorization code. The variables and calculated value for the authorization code are sent to the validation unit, which calculates the authorization code and determines a match between the values for the variables as determined by the calculating apparatus and the values as verified by the validation unit. The validation unit allows payment authorization only if a match exists between the values for the variables as determined by the calculating apparatus and as verified by the validation unit.
