5 biometric tools to replace passwords in the future

There are many things that make you special, such as humor, dance, personal style, shape of ears. Therefore, the ears will become one of the biometric tools, besides heart rate, gait, face or keyboard typing, capable of replacing passwords.

Passwords are used by a lot of people, but the hard-to-remember string of numbers and letters is increasingly losing safety and difficult to manage. Therefore, CNN page predicts the next wave of security will be biometric identification , ie using behavioral and biological characteristics such as fingerprints, gait and even ear shape to determine Get identity.

In fact, now you may have the equipment needed to detect these characteristics. Smartphone is equipped with powerful sensors that can be used to ensure you are yourself. Smartphones have accelerometers, gyroscopes, touch-sensitive screens, microphones and high-resolution cameras, all of which can gather information about physical and behavioral characteristics that no one is like. Come on.

Fingerprint is the most popular biometric identification. Apple soon adopted this technology by embedding the fingerprint sensor on the Home button of iPhone 5s. However, biometrics is still far from replacing passwords - they have bottlenecks to be addressed, moreover, to identify biometrics compatible with existing systems will take some time. In addition, many people are concerned when it comes to collecting information in databases that identify people.

However, the change is coming. Here are five biometric features that will become part of the next wave of identification technology, based on the speculation of CNN:

Heartbeat

The operation of the heart and electrical signals of the heart are very different characteristics of each person and are difficult to copy. ECG reading technology (ECG) has been around for years, but recent advances have narrowed sensor devices into very small devices. For example, an exercise device worn by a person or a surface embedded next to a smartphone can detect heart rhythms. Apple even registered a patent on an embedded heart rate monitor for iPhone.

An interesting product being developed is the Nymi bracelet. It looks like a typical exercise bracelet, but instead of counting junk steps, it detects heart rate to confirm your identity.

It is worth mentioning that it does not use your heart rate to unlock a device. Nymi bracelets are designed to replace physical keys and passwords, by wirelessly confirming your identity on smartphones, computers, doors, cars and even in stores. It can also recognize gestures, so you can unlock the house with a wave of your hand.

Similar technology may appear on other devices, including smartphones. Fitness devices were able to monitor the heart rate as part of the health monitoring function, so it was only a small step when using the heart rate as a means of security.

The shape of the ear

Sensitive touch screen is not only able to identify clapping or clapping behavior. With software and phones, they can recognize the shape of human ears.

That's the idea behind Android Ergo by Descartes Biometrics. When the ear is pressed against the screen, the points that touch the glass will be outlined and compared to an ear-shaped print that has been stored in the device. If appropriate, the user has been authenticated. The application is adjustable and may require multiple scans to meet the highest security needs, or just a scan with people who feel they are not at risk when losing their phone.

Currently, this application is limited to unlocking phones only. But in theory, the ear can be used to identify on the phone for a number of purposes, such as buying and selling in the app store or logging into services.

There are some potential benefits when using shape in comparison to fingerprints. For example, ear size can be scanned with current technology. Therefore, there is no need to spend more money to equip dedicated scanning sensors. In addition, it is possible to recognize the ear shape from an image, which can benefit law enforcement practitioners when studying surveillance videos or photos. Moreover, fingerprints can change over time as people work, hands may be damaged or altered by age. Ear biometrics supporters claim their ears have not changed nearly all their lives.

Gait

Have you ever heard someone coming and immediately knew who it was, or recognized a friend from afar when looking at how they moved? That is the power of identification method through gait.

For the past 30 years, researchers have explored the technology of walking gait with high-resolution videos and specialized floors that can sense pressure. Recently, the explosion of cheap motion sensors like accelerometers and gyroscopes has brought new chapters to this field.

Fitness equipment worn by a person or smartphone will move with the body when you walk. Many things count steps and speed. With sensors and devices, devices will be able to analyze a person's steps and determine if they are the legal owner of the device.

The benefit of gait recognition is that it can collect the necessary information about user habits and users will not need to touch the device or look at the camera.

Typing speed

Typing, as well as walking, are different for each person. Typing biometric technology will record how a person typed and calculated, how fast and how. It will determine how long they hold each key and the time interval between different words.

Online learning site Coursera offers a "Signature Tracking" service for students who want to be certified for the course they have taken. When organizing online classes, anyone can play a student. So Coursera has set up a profile, requiring students to type in a sample phrase. When they need to prove their identity, they will retype the phrase.

Keystrokes can be used to authenticate anyone who is working on a computer, so this system may appeal to companies that are wary of unauthorized users of their internal systems.

Face recognition

As with fingerprints, facial recognition technology is very popular. Law enforcement organizations and many other organizations are building databases to take advantage of recent advances in facial recognition technology.

To successfully identify faces, the device needs a clear, sharp image. Camera on smartphone or tablet has improved very strongly, equivalent to the type of travel camera. The software looks for facial patterns, such as the distance between the eyes, to identify people.

Samsung is one of the companies that have taken advantage of advanced camera technology and now has an unlock feature with face detection on Galaxy smartphones. This feature is still quite new because elements such as lighting and capturing can produce false results.

Recently, Facebook has boasted about its own face recognition project - called DeepFace - almost exactly. The company also claims to be able to recognize faces from one side as well as from the front.
