Think of the number of things in use today for controlling access to anything; keys, cards, passwords, PINs, and the list goes on. Biometrics is the key to a key-free world, where you don\u2019t need to memorize anything or carry multiple access devices, since the access device is you.<\/p>\n
With biometric technologies like fingerprint scanning, facial and voice recognition, and even iris recognition becoming popular in smartphones, authentication can be made more secure and convenient. In fact, many smartphone apps already use biometric authentication for authorizing payments.<\/p>\n
As with any emerging technology, there is a world of possibilities as well as a few concerns:<\/p>\n
This makes many people skeptical, since collecting and processing biological patterns like fingerprints have been almost exclusively associated with criminal investigation.Many privacy advocates also feel that making certain biometric technology mandatory is a violation of civil liberties and constitutional rights.<\/p>\n
Behavioral patterns have already been integrated with biometrics to provide personalized recommendations and even show relevant advertisements. Soon, these may be linked with authentication methods, and e-signatures might replace digital ones. Doctors will be able to easily access your health records to provide better diagnoses,while airports are already using single-token biometric passports to replace multiple checkpoints.<\/p>\n
