In this fast-paced, information-charged era, portable electronic devices such as mobile phones have become indispensable to our daily lives. They allow us to interact with the world and enjoy ourselves, during work, in our personal lives, or when we seek entertainment. An electronic device is like a world in itself, providing us not only with slick apps but also a sense of security—we are so used to having phones around us that we feel uncomfortable and insecure without them.

In order to enhance this sense of security, the vast amount of private information stored on phones must be strongly protected. At present, facial recognition is undoubtedly one most secure, effective, practical, and convenient security protections, when compared to password, fingerprints, or other forms of security. Its working principle is to analyze facial features and complete a facial comparison quickly, on the basis of having already obtained facial feature images. Facial recognition is widely used in scenarios such as logins and payments to protect user privacy.In this fast-paced, information-charged era, portable electronic devices such as mobile phones have become indispensable to our daily lives.

Huawei deeply respects individual privacy and strives to continuously develop security technologies to overcome limitations and provide continuous optimizations and upgrades. Huawei's facial recognition technology uses 3D structured light technology involving 3D depth-sensing facial technology (which consists of multiple sub-modules including a structured light module, secure running environment, facial recognition algorithm, and upper-layer applications) to capture 3D facial data, resulting in more accurate capture of facial information and faster facial recognition. This achieves improvements in both accuracy and security.

Security: all day, all night

Huawei's 3D facial recognition technology is based on the principle of 3D structured light. The structured light module includes a speckle projector, an infrared illuminator, and an infrared camera. When recording facial data, the speckle projector projects 30,000 invisible specks of light onto facial features to obtain face depth information. At the same time, the infrared illuminator is turned on to help obtain facial feature information. With this information, and the image taken by the infrared camera, accurate facial data can be obtained.

Compared to coded structured light, the lights projected by the speckle projector are random and therefore more secure. In addition, the infrared camera can accurately identify facial features such as the nose tip, pupil reflections, or cheekbone shadows by recognizing key facial points, and through 3D anti-counterfeiting. Thanks to the infrared camera and the speckle projector, facial features can be recognized even in backlit or low-light environments, allowing users to unlock their phones with their faces both in the day and at night.

Such highly accurate facial recognition allows for unlocking within milliseconds, providing a fast and smooth experience.

Security: 360-degree personalization

3D facial features are hard to copy. As a cutting edge technology, 3D facial recognition is an improvement on fingerprint recognition and 2D facial recognition technologies and has an error rate of only one millionth.

Huawei 3D facial recognition technology uses 3D structured light to create 3D anti-counterfeiting labels, greatly improving accuracy and security.

Hardware-based encryption and anti-theft feature: Recorded facial data is processed to remove some information while retaining key features. Therefore, even if the phone is stolen, facial data cannot be restored, preventing the facial data from being stolen.

Preventing unlocking the phone with photos: The reflectivity of infrared light varies on different objects. Therefore, Huawei 3D facial recognition technology is able to accurately identify and reject printed photos, electronic photos, videos, silicone masks, or 3D models, preventing other people from using the user's photos or videos to unlock the phone.

Preventing unlocking the phone when user's eyes are closed: Huawei 3D facial recognition technology can detect whether the user's eyes are closed. The phone is unlocked only when the user looks at the screen with both eyes open. This effectively prevents other people from unlocking the user's phone when the user is asleep.
