ENHANCED BIOMETRIC MULTIFACTOR AUTHENTICATION FOR TRANSACTIONS

原文（中文）

The present invention relates to an enhanced biometric authentication technique designed for secure retail transactions. A multifactor authentication process is integrated with facial recognition, facial expressions, and hand gestures. When a customer, previously registered with a third-party facial recognition service, is identified at a retail terminal, a loyalty identifier is retrieved, and the transaction begins. For heightened security during payment, the customer is required to perform at least two pre-registered biometric actions-either facial expressions and/or hand gestures-within a predefined time interval. Upon successful authentication, automatic payment is processed on behalf of the user for a transaction. This multiple factor authentication not only bolsters security against fraud but also ensures that the transaction is conducted with the customer's active participation/consent. The system's flexibility allows customers to pre-register their biometric data and set preferences for the authentication sequence and timing, significantly enhancing both security and user experience in retail settings.
