The iris is one of the most unique structures in the human body. The formation of the iris is determined by genetics, and the human gene expression determines the morphology, physiology, color and overall appearance of the iris. After about eight months of development, the iris has basically developed to a sufficient size and entered a relatively stable period. Unless unusual abnormalities, physical or mental trauma, may cause changes in the appearance of the iris, the morphology of the iris can remain unchanged for decades.
Therefore, the iris has a high degree of uniqueness, stability and unchangeable characteristics, and can be used as a material basis for identification.
In people's minds, "eyeball unlocking" becomes a symbol of "high-tech". The common unlocking method is still unlocking the password and unlocking the fingerprint. Although the face can be unlocked because of the development of the mobile field, the devices related to the unlocking of the iris are still very mysterious.
Scan the eye to unlock the computer <br> <br> want in reality, this can have such a cool way to unlock? A company called EyeLock launched a device called Myris that allows you to scan the eye and unlock your computer.
Scan the iris and enter a mysterious vault, which is often seen in movies.
Myris's appearance is similar to Nest's. Nest's middle is where the screen is. It is replaced with a mirror. Above the mirror is a camera. The device integrates a new biometric scanner and a password manager. It stores and manages your passwords through the app. When you encounter a place where you need to fill in a password, you can log in by scanning the eyeball.
EyeLock said that such a solution can prevent people from entering passwords on their own initiative and allow people to use longer passwords without having to remember them. This point, I believe people who use 1Password will feel more.
Similar to TouchID, the biological information recorded by Myris is not stored in the cloud, but is limited to local access. Also, it scans your iris for a unique ID, so it doesn’t store photos or videos of the iris.
EyeLock also believes that the biological feature of the iris is more secure than fingerprint scanning and TouchID, and only DNA can exceed it. In the field of human biometrics, false acceptance rate is a very important indicator. The lower its value, the more accurate it is to identify, and the less likely it is to make mistakes. The false recognition rate of iris recognition is 1/1500000, and that of TouchID is 1/50000.
It is said that the time required for iris recognition will increase the recognition speed to 1 to 2 seconds in the future.
Iris scan phone
Since the iPhone 5s was equipped with fingerprint recognition, many manufacturers began to launch mobile phones equipped with fingerprint recognition. Fingerprints are the only identity authentication for everyone and the security is really high. However, because of the uniqueness of the fingerprint, once the fingerprint is leaked, it will not be able to solve the problem by changing the password like the usual digital password, and it will be a lifetime password leak. Like the fingerprint, the iris is the exclusive pattern of everyone, and the possibility of being stolen is very small. Recently, ViewSonic has exposed a new machine, which is equipped with advanced iris recognition technology to identify humans entering the mobile phone by scanning the iris of the human eye. It also appears to support iris payment services through the promotion video. It looks very cool.
Of course, the reason why TouchID technology is widely loved by everyone is not only because of its security, but also because it is completed in the moment of pressing the phone to unlock, without any learning costs, unknowingly completed everything. While the mobile phone equipped with the iris technology needs to place the mobile phone camera parallel to the eyes when unlocking, letting the identification time be ignored, it is really a strange action to constantly unlock the mobile phone with the eyes in public places. Iris unlock, in the end is dazzling technology, or can really take over fingerprint identification to improve security and to the public, need to see the final product experience, let us wait and see.
However, the most promising place for iris recognition technology is smart homes. When many devices are connected to the Internet, how can it guarantee the security? There is no very convincing solution at the moment, and iris recognition may be one of them.
