What is Biometric Identification?
Biometric Identification is the latest in cybersecurity. Biometric Identification Techniques use the unique identifiers of the human body to recognize who a person is. Until recently, biometric identification might have seemed like the stuff out of science fiction movies, but it is quickly becoming commonplace. In fact, many people use it to unlock their own cell phones. That’s right, unlocking your phone by touching your finger to the home button is a type of biometric identification. Newer versions of the IPhone also use face recognition as a security measure–another form of biometric identification. So what is biometric identification and what are some of the most commonly used techniques.
Fingerprint Image Processing
Fingerprint Image Processing is the oldest biometric identification technique and the one many people are most familiar with. If you have worked in a government job, you have likely had images taken of your fingerprints. Additionally, crime scene investigators have been using fingerprint identification for a long time. It is quick and easy, but there are some roadblocks that come with it. Although it is not easy, fingerprint images can be forged.
Facial recognition is perhaps the most human-like biometric identification technique, as it is the one humans use on a regular basis. We are used to recognizing people from their faces. This technique simply teaches computers to do the same. Despite the simplicity of it, unfortunately accuracy is low at this point. There is plenty of research into this technique, though, so we may see improvements in the near future.
Voice analysis is an inexpensive biometric identification technique, but one of the easiest techniques to forge. Many high quality voice recordings have tricked voice analysis software, so it is best to use this technique in conjunction with another for top security.
Iris scanning is a biometric identification technique that is becoming more popular in the cybersecurity community. There are some major disadvantages, though. Some users have complained the machine is uncomfortable and unhygienic, due to having to place your chin on a chin rest that is used frequently by numerous people. There have also been instances where a high quality picture of a person’s eye has been able to trick iris scanners.
Retina scans are similar to iris scans, but much more difficult to fake with a picture, due to the retina’s location in the eye. Although retina scans are more secure, they are also highly expensive. Due to the retina scans high level of accuracy; those with top security needs may choose to use it. Due to the cost, however, every day use of this technique is not likely in the near future.
Palm Vein Pattern Recognition
Another high cost-high accuracy technique is the Palm Vein Pattern Recognition. It is virtually impossible to fake the palm vein patterns of another person. An infrared scanner looks at the patterns beneath the skin on your palm. This technique is great for high security needs, however, it too comes with a high price tag. Companies with high cybersecurity needs may want to prioritize this technique.
