Abstract
A biometric authentication smart card may include a biometric authentication sensor configured to sense at least two types of biometric information of a user and to generate raw images therefrom; and processing circuitry configured to, generate a matching template including biometric features based on the raw images, select a user index from among a plurality of user indices based on the matching template, and output, to a payment terminal, payment class information and payment means information set adaptively for the user index.
Claims21
A biometric authentication smart card comprising:
- a biometric authentication sensor configured to sense at least two types of biometric information of a user and to generate raw images therefrom;
- and
- processing circuitry configured to,
- generate a matching template including biometric features based on the raw images,
- select a user index from among a plurality of user indices based on the matching template, and
- output, to a payment terminal, payment class information and payment means information set adaptively for the user index.
A smart payment system comprising:
- a payment terminal configured to request a payment amount based on sale-related information, and to approve a payment by comparing the sale-related information and the payment amount with payment class information;
- and
- a biometric authentication smart card configured to be accessed by the payment terminal, the biometric authentication smart card including processing circuitry configured to,
- generate a matching template based on biometric information of a user,
- select a user index from among a plurality of user indices based on the matching template, and
- output, to the payment terminal, the payment class information and payment means information set adaptively for the user index.
A biometric authentication smart card comprising:
- a biometric authentication sensor configured to sense biometric information of a user and to generate a raw image therefrom;
- and
- processing circuitry configured to,
- generate a matching template including feature points based on the raw image,
- select a user index of a verification template corresponding to the matching template among a plurality of stored verification templates, and
- output, to a payment terminal, payment information based on the user index such that the payment information output to the payment terminal based on a first user index is different from the payment information output to the payment terminal based on a second user index.
