Abstract
A fingerprint authentication method and an electronic device are provided. The fingerprint authentication method includes: performing a fingerprint enrollment operation through a fingerprint sensor and storing enrolled fingerprint information to a storage circuit; sensing to-be-authenticated fingerprint information through the fingerprint sensor in a fingerprint authentication operation; and performing a default function corresponding to an authentication success of the fingerprint authentication operation and updating the enrolled fingerprint information according to authenticated fingerprint information if a similarity between the to-be-authenticated fingerprint information and the enrolled fingerprint information conforms to a default condition.
Claims10
A fingerprint authentication method for an electronic device comprising a fingerprint sensor and a storage circuit, the fingerprint authentication method comprising:
- performing a fingerprint enrollment operation through the fingerprint sensor and storing enrolled fingerprint information to the storage circuit;
- sensing to-be-authenticated fingerprint information through the fingerprint sensor in a fingerprint authentication operation;
- and
- performing a default function corresponding to an authentication success of the fingerprint authentication operation and updating the enrolled fingerprint information according to authenticated fingerprint information if a similarity between the to-be-authenticated fingerprint information and the enrolled fingerprint information conforms to a default condition.
An electronic device comprising:
- a fingerprint sensor;
- a storage circuit;
- and
- a processor coupled to the fingerprint sensor and the storage circuit,
- wherein the processor is configured to perform a fingerprint enrollment operation through the fingerprint sensor and store enrolled fingerprint information to the storage circuit,
- the processor is further configured to sense to-be-authenticated fingerprint information through the fingerprint sensor in a fingerprint authentication operation, and
- the processor is further configured to perform a default function corresponding to an authentication success of the fingerprint authentication operation and update the enrolled fingerprint information according to authenticated fingerprint information if a similarity between the to-be-authenticated fingerprint information and the enrolled fingerprint information conforms to a default condition.
