Claims13
A method of authenticating a candidate fingerprint of a finger of a user by means of a fingerprint authentication system comprising a fingerprint sensor and processing circuitry connected to the fingerprint sensor, wherein the method comprises the steps of:
- receiving, by said processing circuitry, an authentication request for the finger of the user;
- acquiring, by said processing circuitry, fingerprint data using the fingerprint sensor;
- determining, by said processing circuitry, a second plurality of fingerprint features of the finger from the fingerprint data;
- dividing, by said processing circuitry, the second plurality of fingerprint features into a second basis set of features and a second detailed set of elements related to the second basis set of features;
- and
- receiving from a computer memory, by said processing circuitry, a first detailed set of elements relating to the finger of the user;
- combining, by said processing circuitry, the second basis set of features with the first detailed set of elements, forming a third plurality of fingerprint features;
- comparing, by said processing circuitry, the second plurality of fingerprint features with the third plurality of fingerprint features, and
- providing, by said processing circuitry, an authentication signal indicative of a result of the comparison.
An electronic device, comprising:
- a fingerprint sensor providing fingerprint data representing a finger of a user arranged at the fingerprint sensor;
- and
- processing circuitry connected to the fingerprint sensor, wherein the processing circuitry is configured to:
- acquire fingerprint data using the fingerprint sensor;
- determine a second plurality of fingerprint features of the finger from the fingerprint data;
- divide the second plurality of fingerprint features into a second basis set of features and a second detailed set of elements related to the second basis set of features;
- and
- receive a first detailed set of elements relating to the finger of the user from a computer memory;
- combine the second basis set of features with the first detailed set of elements, forming a third plurality of fingerprint features;
- compare the second plurality of fingerprint features with the third plurality of fingerprint features, and
- provide an authentication signal indicative of a result of the comparison.
A computer program product comprising a non-transitory computer readable medium having stored thereon computer program means for controlling an electronic device, the electronic device comprising:
- a fingerprint sensor providing fingerprint data representing a finger of a user arranged at the fingerprint sensor, and
- processing circuitry connected to the fingerprint sensor,
- wherein the computer program product comprises:
- code for receiving an authentication request for the finger of the user;
- code for acquiring fingerprint data using the fingerprint sensor;
- code for determining a second plurality of fingerprint features of the finger from the fingerprint data;
- code for dividing the second plurality of fingerprint features into a second basis set of features and a second detailed set of elements related to the second basis set of features;
- and
- code for receiving a first detailed set of elements relating to the finger of the user from a computer memory;
- code for combining the second basis set of features with the first detailed set of elements, forming a third plurality of fingerprint features;
- code for comparing the second plurality of fingerprint features with the third plurality of fingerprint features, and
- code for providing an authentication signal indicative of a result of the comparison.
