①Fingerprint Characteristics
The features extracted by fingerprint algorithm from the acquired fingerprint image represent the information of the fingerprint. Fingerprint storage, comparison and searching are all done by manipulating the fingerprint features.
Fingerprint processing consists of two processes: fingerprint login process and fingerprint matching process [where fingerprint matching is divided into fingerprint comparison (1:1) and fingerprint search (1:N)].
In fingerprint registration, each fingerprint is entered twice, and the images of the two entries are processed and synthesised into a template to be stored in the module.
When fingerprint matching, through the fingerprint sensor, the fingerprint image to be verified is recorded and processed, and then matched and compared with the fingerprint template in the module (if matched with a template specified in the module, it is called fingerprint matching method, i.e. 1:1 method; if matched with multiple templates, it is called fingerprint search method, i.e. 1:N method), and the module gives the result of the match (pass or fail).
