Abstract
A non-directional fingerprint and palmprint identification method and a non-directional fingerprint and palmprint data creation method. In the fingerprint and palmprint identification method, a fingerprint and palmprint identification device detects and scans the fingerprints and palmprint of a user to generate a fingerprint and palmprint image and transmit the image to a processor. The processor identifies and calculates the fingerprint and palmprint image to obtain the fingerprint of a specific finger and the palmprint. According to at least one reference line and the fingerprint of the specific finger and the palmprint, the processor identifies and processes the intersection points to generate multiple intersection points. Then the processor calculates and processes the distances between the intersection points to generate multiple characteristic points and converts the characteristic points into digitalized characteristic data to compare the characteristic data with the characteristic data stored in a characteristic database to generate a comparison result.
