Validation identity tokens for transactions
Last updated:
Abstract:
A user initiates a transaction by providing identification data at an access device. Certain elements of a validation identity token, such validation keys, may be distributed among several remote server computers. After the elements are retrieved during the transaction, the validation identity token may be generated using the retrieved elements. The validation identity token may indicate whether the user is authenticated. No single entity can possess all elements utilized to generate the validation identity token, which mitigates risk of the validation identity token being compromised. In some embodiments, the validation identity token may be a chromatic identity token, which may indicate validity by color.
