Common biometric comparisons.

Biotechnology Channel News: With the rapid development of biometric technology, users often ask: biometric technology so many categories, choose which is the most appropriate? In addition to the fingerprint recognition that has been talked about above, there are common face recognition, iris recognition, which technology is better?In one case, there are three ways to authenticate individuals: 1) what you have, such as an NFC phone, a smart card, 2) what you know, such as a PIN, password, and 3) and finally yourself.
cards, tokens, PIN verification, etc. can only be 100% sure that the contact information is correct, but it is difficult to guarantee that this person is real.
biometrics brings a ring of validation between people and behavior, and another benefit is convenience.
you won't lose it, forget it or share it with others.
End-user experience and the quality of biometrics are equally important, including three factors: 1) there is no doubt that the quality of hardware products is a key factor in image input quality, the selection of a reliable hardware product is the basis of biometrics;
have their advantages and limitations in all kinds of biometric technologies.
fingerprint is the most widely used and mature technology, but also the starting point of biometric applications.
fingerprint identification is relatively cheap, functional, but also a very reliable way to verify.
, but if you need more advanced security options, a fingerprinter and smart card or a fingerprint card and password are a good choice.
low-level security options are typically applied to a phone or tablet and interact with the user through sensors.
, fingerprint recognition still has significant limitations on some difficult fingers (peeling, etc.) and recognition conditions (wet fingers).
iris recognition has been hailed as the most accurate and safe way to identify biometrics.
, the cost of iris recognition is also relatively high, and the need for professional hardware products.
But with the maturity of iris recognition technology, the current iris recognition costs are no longer a "stunning" state, manufacturers have even developed a sophisticated, compact mobile terminal dedicated iris module, cost-effective.
is closely followed by safe and accurate biometric authentication, providing high-quality authentication similar to fingerprint identification, or interacting directly with users.
face recognition is non-contact recognition, very friendly and convenient, but also a better way to use the camera.
can be used in a wide range of environments, including construction sites, mobile devices, website logins, and even without specialized hardware support.
speech recognition is also a very convenient way to recognize.
is a quick and easy verification solution for mobile devices.
but voice quality control is one of the key factors affecting its recognition and development, and its security is a concern, but it can still make a big impact on call centers and customer service.
, such as electronic signature, gait recognition (walking contours), earprint recognition and other new technologies, is still in a wait-and-see state.
there is no uniform answer to which biometric method to choose, depending on what the user is doing, but there are general principles.
1, low-cost solutions still favor fingerprints, sometimes with smart cards or passwords attached.
2, mobile solutions usually use face and voice, fingerprints are also very popular, but now iris recognition has gradually become one of the important means of competition among mobile phone manufacturers.
3, if you want contactless recognition, you tend to face recognition or iris recognition.
4, secret monitoring tends to face recognition, speech recognition and gait recognition.
5, large-scale projects often use fingerprints or irises, such as Chinese identity cards will be included in fingerprints, India biometric projects will include iris recognition and so on.
6 and higher security levels tend to be iris or finger vein recognition, often combined with cards or passwords to form multi-factor authentication.
7, if the certification conditions or environment is relatively harsh, tend to iris recognition, because iris recognition is less affected by external factors, such as mine iris solutions.
