Patent

CA 2639662

Data to be exchanged in a transaction is protected by using a hashing function to transform sensitive data into a scrambled form. The hashing function can use as its inputs data derived entirely or in part from portions of the data to be exchanged. The hashing function can also use as its inputs data derived entirely or in part from other locally available data. The output of the hash function is then transmitted to a destination that attempts to recreate the output of the hash function in order to validate the data transmission.
