Abstract:
A method of authenticating the execution of a negotiable instrument by the maker of a negotiable instrument having a front face and a back face when the negotiable instrument is presented to a payee for payment to the maker of the negotiable instrument comprising:(a) emplacing a numeral identification number of the front of the negotiable instrument;(b) emplacing marking means on the front face of the negotiable instrument that can be marked by the maker of the negotiable instrument when presented, to incorporate coded symbols identified with the maker of the negotiable instrument;(c) comparing the numeral identification number with the coded marking symbols emplaced on the front face of such negotiable instrument, according to the following mathematical relationship using in conjunction with any set of numbers on the front face of the check 10 would be: ""R"" (R) is the resultant unadded sequence of integers or numbers a', b', c', d', e', f' . . . such latter numbers being respectively and individually the separate product of (Z+Y)+(X+W)+(V+U)+ . . . where Z is the first of the verity coded numbers and Y is the last number of the numbers of any numbered sequence on the check, and X is the second of the verity code numbers and W is the second from last of the numbered sequence used on the check and V is the third of the verity code numbers and U is the third from last of the numbered sequence used on the check, and where the exact number of digits comprising the unadded sequence R for the code may vary from 1 up to any higher number using the foregoing algorithmic sequential approach.
