Abstract
A method and apparatus for recognizing a fingerprint in an electronic device includes recognizing a fingerprint that is input through a touch-based device, determining whether the recognized fingerprint is a white image, and when the recognized image is determined to be a white image, displaying on a display screen a request for a fingerprint retouch.
Claims18
A method for fingerprint authentication in an electronic device, comprising:
- recognizing a fingerprint in responsive to a touch input to a touch input unit;
- detecting whether the recognized fingerprint is a white image;
- displaying a request for a fingerprint re-touch on a display if the recognized fingerprint is detected to be the white image;
- increasing a count of a number of times a fingerprint authentication process failed if the authentication process fails;
- and
- maintaining a current total of the count if the recognized image is determined to be the white image.
3 more elements
An electronic device comprising:
- a display;
- a touch input unit;
- a fingerprint recognition device configured for recognize a fingerprint in responsive to a touch input on the touch input unit;
- at least one memory;
- and
- a processor configured for
- detecting whether the recognized fingerprint is a white image,
- displaying on the touch display a request for a fingerprint re-touch if the recognized fingerprint is detected to be the white image,
- increasing a count of a number of times a fingerprint authentication process failed if the authentication process fails, and
- maintaining a current total of the count if the recognized image is determined to be the white image.
7 more elements
A method for recognizing a fingerprint in an electronic device, comprising:
- recognizing a fingerprint in responsive to a touch input;
- detecting whether an area of the recognized fingerprint is smaller than a reference value;
- responsive to the area being smaller than the reference value, displaying on a display screen a request for a fingerprint re-touch;
- increasing a count of a number of times a fingerprint authentication process failed if the authentication process fails;
- and
- maintaining a current total of the count if the recognized image is determined to be a white image.

8 more elements
A method for recognizing a fingerprint in an electronic device, comprising:
- recognizing a fingerprint in responsive to a touch input;
- detecting whether the recognized fingerprint matches a pre-stored fingerprint;
- detecting whether the recognized fingerprint is a white image if the recognized fingerprint does not match with the pre-stored fingerprint;
- and
- displaying on a display screen a request for a fingerprint re-touch if the recognized image is detected to be the white image;
- detecting that fingerprint authentication has failed if the recognized image is detected not to be the white image;
- increasing a count of a number of times a fingerprint authentication process failed if the authentication process fails;
- and
- maintaining a current total of the count if the recognized image is determined to be the white image.
