Abstract
Devices and methods for signature authentication of a bearer of a payment processing device during financial transactions are provided. The payment processing device is provided with a signature input panel configured to receive user input signature information for the purpose of authenticating the signature. After the bearer of the payment processing device writes her signature into the signature input panel, the input signature information is compared to a pre-stored signature profile stored in the payment processing device for authentication.
Claims16
A method of authenticating a user of a card during a financial transaction, comprising:
- capturing user input signature information comprising changes in 4-dimensional characteristic parameters of the user's signature on a signature input panel provided in the card, wherein the signature input panel comprises a plurality of sensing layers and is configured to measure changes in pressure when pressure is exerted on the signature input panel by monitoring a number of activated pixel points between successive pair of the sensing layers;
- comparing the user input signature information to a pre-stored signature profile;
- and
- outputting results of the comparing of the user input signature information from an output device provided in the card.

- authenticating the user input signature information;
- outputting an indication of results of the authentication;
- activating a communication element provided in the card when the user input signature information is successfully authenticated;
- and
- maintaining a deactivated status for the communication element when the user input signature information is not authenticated.
A non-transitory machine-readable storage medium, encoded with a computer program code, such that, when the computer program code is executed by a processor, the processor performs a method for authenticating a user of a card during a financial transaction comprising:
- capturing a user input signature information comprising changes in 4-dimensional characteristic parameters of the user's signature on a signature input panel provided in the card, wherein the signature input panel comprises a plurality of sensing layers and is configured to measure changes in pressure when pressure is exerted on the signature input panel by monitoring a number of activated pixel points between successive pair of the sensing layers;
- comparing the user input signature information to a pre-stored signature profile;
- and
- outputting results of the comparing of the user input signature information from an output device provided in the card.
