Does biometric technology meet your security needs?

Vance Bjorn, founder of DigitalPersona, a developer and supplier of biometric technology systems, said, "Biometric technology is inherently safer than passwords and most other commonly used identification methods. Anyone can pick up a password, smart card or your visa card and use it, but biometrics can let the system know clearly who is operating it, and biometrics can also be applied to many applications. " Fingerprint reader is one of the most widely used biometric devices. Fingerprint readers entered the mainstream market a few years ago, when manufacturers were still applying this technology to the keyboards of notebook computers and desktop computers. By then, the same fingerprint identification technology can also provide independent identification equipment for various security applications. Vance Bjorn pointed out that there is a natural connection between fingerprint and identity protection, and fingerprint is widely regarded as the most reliable way in the field of identity identification. Although fingerprint scanning is cheap and accurate, it is not as foolproof as other biometric technologies. Fingerprint readers can also be fooled, for example, a real fingerprint can be stamped with latex fingers. Some fingerprint readers can also recognize this kind of fingerprint, that is, the fingerprint formed by using laser printer toner, and then transferred to the copier. Another disadvantage of fingerprint identification is that some disabled people can't use this technology. Eyes are another human feature used by biometric technology developers. Most experts believe that iris recognition system has high reliability, and the accuracy of this recognition technology even exceeds that of DNA detection, and we all know that DNA detection is an invasive, expensive and inconvenient authentication method. During authentication scanning, iris acts as a kind of "human body barcode", that is, a unique code composed of complex connective tissue and other visible light features. In the whole human race, no two people have the same iris, even between identical twins or triplets. The biggest disadvantage of iris recognition technology is its high price, and the entry-level iris recognition system costs thousands of dollars or more. Similar to fingerprint readers, developers need to provide disabled users (users without iris scanning) with a way to access protected systems. Because of its uniqueness, facial recognition is increasingly favored by people. This technology is a very passive recognition technology, which allows people to scan their faces without being noticed. Some police agencies have used security cameras combined with facial recognition software to match people's faces in order to find out the criminals stored in those databases. The function of face recognition is to identify by analyzing faces and measuring facial features (such as measuring the proportion of eyes, mouth and nose). With the help of special calculation method, it can be matched with the face pictures stored in the database. However, there are some limitations in using facial recognition function as an access right recognition technology. The basic facial recognition system only costs a few hundred dollars, but the commercial version is more expensive, and it is not very accurate when used in low light conditions, which requires a lot of computing power.
