How unique are you? Today in class we learned about unique physical features, such as our irises, fingerprints, retinas, DNA, and handprints, and how they can be used for identification. Biometrics combines measurements of these individual traits with technology to identify people. For example, many of us now can use our thumb instead of a passcode to unlock our cell phones, or maybe we open up a security door at work with a touch of our hand. As our society becomes even more technological, the uses of our personalized biometrics patterns will only increase!
