Systems and methods for communicating risk using token assurance data

Abstract

Systems and methods for communicating risk using token assurance data are provided. A network token system provides a platform that can be leveraged by external entities (e.g., third party wallets, e-commerce merchants, payment enablers / payment service providers, etc.) or internal payment processing network systems that have the need to use the tokens to facilitate payment transactions. An authorization request message can include a token assurance level code that is indicative of a token assurance level associated with a generated token. External or internal entities may use the token assurance level to evaluate risk associated with a payment transaction that uses the token.

The PAN is passed from a merchant terminal, to an acquirer system, a payment processing network, payment gateways, etc.[0003]Because the PAN can be exposed at various points in the transaction lifecycle, some have suggested that payment “tokens” be used to conduct payment transactions. A token serves as an additional security layer to the PAN and in effect becomes a proxy / surro...

AI Technical Summary

Benefits of technology

The invention describes a network token system that can be used by various entities such as merchants, wallet providers, and acquirers for payment transactions. The system includes a detector that can identify the real account identifier associated with a payment token and generate a modified authorization request message with a token assurance level code based on the transaction history and authentication method. The system can improve the level of confidence associated with the payment token by providing a means for requesting and approving it. The technical effects of the invention include increased security and efficiency in payment transactions and improved user experience.

Problems solved by technology

While conventional efforts to use payment tokens have been useful, a number of additional problems need to be solved.

For example, because the real PAN is not apparent from a corresponding token, it is difficult to identify the source of the token or the issuer of the token.
