Abstract
A method comprising the steps of receiving a request for tokenization from a user, the request including a Session Token; decoding and validating the Session Token; retrieving a token definition, a token key, and a security policy from a database; appending the user key and the token key to the received value to create an input value; replacing each input value character with a known character to create a replacement input value, where the known character is related within a lookup table; generating a secure hash of the replacement input value to create a derived key; substituting each character of the replacement input value with a character from lookup tables to create a third input value, the lookup tables being selected based on the received value, the position of the character being replaced within the replacement input value, and the derived key; and returning the input value to the user.
