1. A fingerprint recognition method, comprising:
- obtaining, by a fingerprint sensor, first input data;
generating, by a processor, a first waveform diagram corresponding to a first minutia of the first input data by taking a first minutia as a center of a circle, taking a first length as a radius to generate a first circumference, and transforming the first circumference to the first waveform diagram;
obtaining, by the fingerprint sensor, second input data;
generating, by the processor, a second waveform diagram corresponding to a second minutia of the second input data by taking a second minutia as a center of a circle, taking the first length as a radius to generate a second circumference, and transforming the second circumference to the second waveform diagram;
andcomparing, by the processor, the first waveform diagram with the second waveform diagram.
