Remote Face-to-Face Authentication for Card Transactions

The patent introduces a Remote Face-to-Face (RF2F) system as an intermediary between the merchant and the cardholder. This system includes a remote authentication service that verifies the cardholder's identity and card presence through multiple authentication factors (biometric data, PIN, card verification value) without requiring physical proximity. The RF2F system acts as a mediator that provides the security of card-present transactions while maintaining the convenience of remote transactions.

The patent changes the authentication parameters from traditional card-not-present methods (card number, expiration date) to card-present level authentication parameters (biometric data, PIN, card verification value). By changing these authentication parameters, the system elevates the security level of remote transactions to match card-present transactions, thereby reducing perceived fraud risk and associated processing fees.

The patent segments the authentication system into distinct functional components: a client device that collects authentication data, a communication network that transmits the data, and a remote authentication service that verifies the data. This segmentation allows each component to be optimized independently and reduces overall system complexity by distributing functions across multiple entities.

The RF2F system is designed to be universal and compatible with existing card-not-present transaction infrastructure. It can process various types of card transactions (credit, debit, prepaid) and works with different authentication methods (biometric, PIN, CVV). The system integrates with existing payment networks and merchant systems, reducing the need for entirely new infrastructure and thereby limiting the increase in device complexity.

The patent implements dynamic authentication where the required authentication factors are adjusted based on the transaction context and risk assessment. The system can require one or more authentication factors depending on the transaction amount, merchant reputation, and detected risk levels. This dynamic approach maintains security while improving user convenience for low-risk transactions.

The system performs preliminary authentication actions during the enrollment process, where cardholder biometric data and other authentication factors are collected and stored securely. This preliminary action allows the actual transaction authentication to be faster and more convenient, as the heavy lifting of data collection and verification setup has already been completed beforehand.
