Which Biometric Technology Is Best?
Say you were deciding to implement or purchase a biometric security system. How would you know which was right for your needs? There are, of course, advantages and disadvantages to each system, and with as many options as there are (and more forthcoming), it’s important to know which is best suited.
Fingerprint and iris scanning are pretty reliable, as each of these features is developed early in life, during the formation of the zygote while in the mother’s womb. Fingerprints and irises don’t tend to change much over the course of a lifetime, so many say that identifying traits like these are a good reason to trust biometric security systems over time.
But fingerprint readers, while small and easy to install, may not be the best bet, as they typically offer less storage capacity and are not as good at managing bulk loads of information. It’s also rare to achieve perfect accuracy. Equally, iris scanning systems have trouble with low or odd lighting, and if direct eye contact is not made it can trip up the system. We’ve written a bit about new and improved iris scanning systems that can capture data among a wider range, so perhaps there are improvements on the horizon. Of course, as technology improves, so does the accuracy, but there are other systems that have returned higher results.
Voice recognition systems have posed some problems based on the continually changing nature of one’s voice. If the change is natural it can make for problems.
We’ve been writing quite a bit about face recognition systems lately, and these seem to be the most fertile ground for biometric security development. An identification system based off an individual’s facial details – the distance between the eyes, lips, ears, etc. – naturally works with a larger database as it needs to store various information for so many aspects of the human face. A face, when rescanned, matches new patterns with older ones, and it could keep a changing log of features over time. Accuracy and reliability are generally higher in previous tests.
We found an article in an online library database that stands as a strong proponent of face recognition systems for security. Face recognition has been studied widely and it seems that it’s commonly understood to be quite accurate and efficient among other identification and security systems.
Either way, whatever system is best-suited for your needs, you can guarantee there will be another faster, more efficient, and better system coming round the bend.
