Abstract
A system and method are provided for generating access tokens on a user device rather than via a remote server computer. An access token can be generated on a second user device by combining and encrypting, with format preservation, a primary access identifier, variable value, and salt. The resulting value can be provided to a first user device that can subsequently can provide the access token to an access device as part of an interaction. The access device can generate an authorization request message that comprises the access token and transmit it to a remote server computer for processing. The remote server computer can process the access token to determine the primary access identifier despite not being involved in the generation of the access token, providing an improvement over conventional tokenization methods.
