What are the characteristics of Win10 facial recognition and iris recognition? What is the difference between the two?

 Windows Hello uses fingerprints, facial recognition, irises and other biometrics to provide another level of security beyond passwords, while Windows Hello save and set unlocking schemes can be used for Windows 10 operating systems, licensed applications, and read data. , login to websites and services.

Win10 Biometric System Windows Hello has three recognition modes: face, iris and fingerprint. For fingerprint recognition, many older devices have this capability, and Windows Hello can also use existing devices for identification. But for facial recognition and iris recognition, many users are not very familiar with it. What are the characteristics of these two identification methods? Let's take a look at it today.

▲Intel RealSense F200

Face Recognition

This feature is currently only available through the Intel RealSense F200 Reality Camera. Some new models of laptops have been integrated. Equipment, there will be more such new products coming out in 2016. The device consists of three parts: an infrared module, a 3D module, and a normal camera. It can be used not only for face recognition, but also for fingerprint tracking, speech recognition, augmented reality, and background segmentation research.

F200 is similar to Microsoft's somatosensory device Kinect, both have 3D image scanning function, users can log in to Windows10 through F200 & ldquo; brush face & rdquo; The working distance of this device is between 0.2m and 1.2m, which allows you to complete the "natural brush" face verification.

The efficiency of this method is much higher than the traditional password login method, which can be completed in an instant. And the security is higher, which saves the difficulty of password memory. At the end of the article, there is the latest Windows Hello face and fingerprint recognition feature introduction video. Friends who like this feature can click to watch.

Iris Recognition

In fact, there are at least two common techniques for eye recognition, namely retinal recognition and iris recognition. The former requires professional equipment to scan the blood vessel pattern at the back of the eye for identification, which is characterized by high precision and high reliability, but the equipment requirements are also very high. In contrast, iris recognition is much simpler, you only need to scan the iris at the front of the eye to complete, ordinary camera /camera can be competent.

In theory, the existing mobile phone camera can complete the recognition function, which means that the existing Windows Phone mobile phone can upgrade the Win10 Mobile without using the addition or modification hardware, you can use the iris recognition, you need to wait for the hardware manufacturer This feature is enabled at the technical level by means of firmware updates and the like. If the camera is to be used for such identification, an LED and a light receiving sensor are required. These lights used to scan the iris are typically invisible (near-infrared) so that the camera can perform the scanning process. Scanning can be done in low-light (even darkroom) conditions, and the scanned person can wear clear contact lenses, traditional glasses, and sunglasses without mirrors.

From a hardware perspective, iris recognition is easier to promote than fingerprint recognition because it requires a common camera, and fingerprint recognition requires dedicated device support. Compared with face recognition, a normal camera is small in size and is generally equivalent to half of the F200.

However, when using iris recognition, the user needs to be closer to the camera so that the camera can capture the iris information. Because of this feature, it is more suitable for use on mobile phones. The latest Lumia 950 and Lumia 950 XL will use this technology soon.

In contrast, although face recognition is more accurate and convenient, but because the current technology is not mature, the camera is large and difficult to integrate into the mobile phone. Maybe it can be transplanted to the mobile phone after future technological advancement. on.

The above is about the characteristics and differences between Win10 facial recognition and iris recognition. Do you understand? I hope to be helpful!
