Advantages and disadvantages of fingerprint recognition technology
advantage
1. Fingerprints are unique features of the human body and their complexity is sufficient to provide sufficient features for authentication;
2, if you want to increase reliability, just register more fingerprints, identify more fingers, up to ten, and each fingerprint is unique;
3, the speed of scanning fingerprints is very fast, very convenient to use;
4. When reading the fingerprint, the user must touch the finger and the fingerprint collection head to each other, directly with the fingerprint collection head;
5. Contact is the most reliable method for reading biological characteristics of the human body;
6, the fingerprint collection head can be more miniaturized, and the price will be more low;
Disadvantage
1. Some people or certain groups have fewer fingerprint features and are difficult to image;
2. In the past, because of the use of fingerprints in criminal records, some people were afraid to “record fingerprints”.
3. In fact, the current fingerprint authentication technology may not store any data containing a fingerprint image, but only store the encrypted fingerprint feature data obtained from the fingerprint;
4. Each time the fingerprint is used, the fingerprint of the user will be left on the fingerprint collection head, and these fingerprint traces have the possibility of being used to copy the fingerprint.
