FINGERPRINT ENCODING METHOD AND SYSTEM, AND FINGERPRINT AUTHENTICATING METHOD AND SYSTEM

摘要

A fingerprint encoding method shows an alphanumeric character or a symbol offered by a system first. Then, users select a desired finger corresponded with the alphanumeric character or symbol to touch the sensor, thereby acquiring a fingerprint image or a fingerprint characteristic value of the finger to save the fingerprint image or the fingerprint characteristic value in a memory area corresponded with the alphanumeric character or the symbol in a memory. A fingerprint authenticating method does not need to set a preset password, while showing a random verification code offered by the system, and users enter the correspondent fingerprints in order according to the random verification code.
