A modern reality is that we have a lot of passwords to remember, and it's becoming a problem. Considering that every day we face a heavy data stream it’s not always easy either to create a hard-to-crack password or to remember it afterwards. However authentication is clearly important. People are trying to get rid of passwords altogether and fingertips are a good way out of the situation. Nevertheless online security market keeps growing. Companies are trying to use other parties of bodies than fingertips as unique “password” of a person. Faces and eyes seem to be on the top of the list of future passwords.
The first tech giant, which implemented finger scanner into its devices, was no other than Apple. Although some users pointed out it didn’t work perfectly and was quite unsecure, other companies (for example Samsung, Nexus/Pixel, LG and HTC) followed Apple introducing fingerprint locks into their gadgets.
Despite the spreading of fingerprint sensors, companies continue developing new biometric methods of logging in. Google revealed its Face Unlock on Android 4.0 Ice Cream Sandwich with facial recognition identification, then the ZTE Grand S3 and the Alcatel Idol 3 released eye-print authentication using a retinal scan to match the user. This technology doesn’t require any additional hardware – your selfie camera is enough. At the same time it takes longer to identify a user by means of retinal scan than by using finger scanner.
Iris scanning may be a pretty good alternative to previously mentioned technologies, as it uses more compact algorithms. That means a shorter period of time to wait for detection. Moreover the technology is rather mature – it has been used by secure labs, buildings and even airport security before. It’s also far more secured than fingertips. The disadvantage of iris scanning is necessity to have an infrared camera. But Samsung has already implemented it in some devices and other brands are likely to follow it.
The payments industry is one of the biggest forces, motivating developing more and more sophisticated technologies of online securing. The most graphic example to it is Apple incorporating NFC into the iPhone 6. Payments giant Mastercard is also taking measures for avoiding simple passwords. The company has been researching biometric-authentication methods using fingerprints, eye-based tech, facial recognition and even heartbeats, considering that these are unique to the user and don't require memorizing. Fingerprints and face detection seem the most easily scalable at the moment. Recently Mastercard launched its "selfie pay" authentication method in Europe. The feature works by taking a selfie and blinking to prove your personality. Public enquiries received predominantly high rating.
It’s obvious that convenience simplicity of fingerprint locking is a sign that this technology is likely to stay and new technologies, such as face- and eye-recognition do not mean to replace it. The new methods may complement finger scanners as they are permanently improved. Until then, we'll have to fight with remembering our complex passwords.
