ALTERNATE PRIMARY ACCOUNT NUMBER GENERATION

摘要

A method for alternate primary account number generation is described. The method comprises receiving, from a device, an input data string containing sensitive data. The input data string comprises a first portion, a second portion, and a third portion. A plurality of values is generated using the second portion of the input data string, wherein each of the plurality of values are of a predetermined amount of numbers, each of the plurality of values having a corresponding key. A first key is selected, based on the second portion, from the plurality of values. A second key is generated using the first key. An output value is selected, based on the second key, from the plurality of values. An output data string is generated using the first portion, the output value, and the third portion.
