With the smart door lock market entering the golden period of development, the product form of smart door lock has become "a hundred flowers blossom". Brand lock enterprises began to embrace the brand-new product form represented by 3D face recognition door locks, and achieved their own "breakthrough" in brand marketing and technical solution innovation. So, is the 3d face recognition smart lock safe? What kind of experience can face recognition smart lock bring to users? Compared with fingerprint identification smart lock, what are the unique features of face recognition and why it is more and more favored by users …
Is the 3d face recognition smart lock safe?
As we all know, 3D face recognition smart lock is better than 2D face recognition smart lock in terms of recognition accuracy, recognition speed and anti-counterfeiting ability, and the experience is better than 2D face recognition smart lock. Therefore, 3D face recognition smart locks have become a battleground for major brands.
The security of face recognition depends on the difference of recognition accuracy and whether it can be detected in vivo, as long as the face smart lock adopts the world’s leading and highest-level face algorithm and recognizes more than 10 thousand feature points of the face. At the same time, it is equipped with infrared camera and live detection to ensure that photos and videos can’t be unlocked, so it is safe and reliable. In order to verify the security of smart face door locks, a professional security testing environment for face recognition door locks was built intelligently and independently. Combined with the face recognition technology detection in the Bank Card Testing Center, standards were formulated, mainly to detect whether the face images obtained by the face door locks were from living bodies or false attacks. Hundreds of thousands of attack tests were carried out on two-dimensional static paper, two-dimensional static electronic images, two-dimensional dynamic images, three-dimensional masks, three-dimensional head molds, etc. Under different external environments such as light, distance and angle, the non-living objects were tested for whether they could be identified as living objects. The test results showed that each attack was not identified as living objects, and the error acceptance rate was less than 0.1%.
For the smart door lock industry, the overall solution of face door lock has good adaptability and high integration, which can reduce many unnecessary debugging links between hardware and algorithms and effectively help smart door lock enterprises reduce development costs and shorten product cycle. At present, it has established in-depth cooperative relations with major door lock manufacturers, and will continue to promote the development of 3D face-brushing door lock industry in the future.
At the same time, Intelligent has established a perfect face recognition door lock detection process and test standard, which can realize multi-dimensional detection. Smart also actively opens the door lock detection service of face recognition, and welcomes all major door lock brands to conduct all-round safety detection and technical exchanges to jointly create safe and convenient door lock products and promote the sound development of the door lock market of face recognition.
The early face recognition technology was mainly 2D face recognition technology, but it was eliminated by the market because of its technical and security problems. Smart locks using 2D face recognition technology may be cracked by plane images such as photos. Because 2D camera can’t receive the third information such as posture, illumination, etc., there is inevitably a loss of facial feature information, which is easily influenced by posture, illumination, expression and other factors, and the recognition rate is not ideal. Especially in terms of security, it is relatively poor, vulnerable to false face attacks, and it is difficult to distinguish twin faces.
However, 3D face recognition is different. At present, 3D face recognition used in the market is mainly divided into 3D structured light, TOF and binocular stereo vision according to the principle of camera imaging. "Door Lock World" learned through Zhihu’s inquiry that 3D structured light projects light with certain structural characteristics onto the photographed object through an infrared projector, and then is collected by a special infrared camera; TOF is simply laser ranging. The illumination light source is generally modulated by square-wave pulses, and the distance is measured according to the time difference between pulse transmission and reception, mainly acquiring and processing human posture data. Binocular stereo vision is a method based on parallax principle and obtaining three-dimensional geometric information of objects from multiple images. Two digital images of the measured object are obtained from different angles by two cameras at the same time, and the three-dimensional geometric information of the object is recovered based on the parallax principle, so that the depth information of each point on the image is obtained, and finally the three-dimensional data is obtained.
In fact, no matter what kind of 3D technology, they all have a common feature, that is, obtaining 3D face data. Theoretically, plane photos can’t crack the 3D face recognition smart lock. That is to say, the smart lock using 3D face recognition technology is safe, and users don’t have to worry about its safety. When buying a smart lock with 3D face recognition technology, it is best to choose a smart lock with 3D face recognition technology.
At present, 3d face recognition lock has the following advantages.
3D face recognition lock refers to establishing millimeter 3D face model for users with 3D camera, and detecting and tracking the features of human face through living body detection and face recognition algorithm, and comparing it with the 3D face information stored in the door lock, so as to complete unlocking after face verification, and realize high-precision identity authentication and non-inductive unlocking. Compared with 2D face door locks, 3D face door locks are not easily affected by posture, expression and other factors, and are not affected by light environment. At the same time, they can prevent attacks such as photos, videos and headgear, and their recognition performance is more stable, which can realize high-precision 3D safe face recognition. 3D face recognition door locks are the door locks with the highest security level of smart door locks at present. The application of 3D structured light mainly includes face unlocking and secure payment. For example, on June 19th, 2018, OPPO’s future flagship Findx adopted the 3D structured light technology provided by Obi Zhongguang, which can realize secure payment, 3D reconstruction, AR, games and many other scenes. In July 2019, a number of 3D door locks using structured light technology were released at Guangzhou Jianbo Fair. For example, the 3D face recognition door locks released by door lock manufacturers such as Kaidishi and Zhijiaren all adopted Obi Zhongguang structured light technology, which can realize 3D face brushing and non-inductive unlocking.
1. Comfortable interaction
The product audio-visual feedback system of face recognition smart door lock is very developed. Users only need to walk in front of the door lock and brush their faces to open the door. Compared with traditional door locks and smart fingerprint locks, it is more comfortable in interaction.
2, high security
The security of smart door locks based on face recognition is higher than that of smart fingerprint locks. After all, one is to brush the face to unlock, and the other is to unlock with fingerprints. Only after some people go to Korea for plastic surgery, they will be able to open the door according to the owner’s face. It is impossible to open the door by violence in other ways, and the security is more obvious.
3, the convenience of operation
The face recognition intelligent door lock is not much different from the intelligent fingerprint lock in management operation. Compared with the traditional door lock management, it can be said that it saves consumers a lot of labor, which is also a favorite point of consumers.
4, strong durability
The service life of the face recognition smart door lock is very long. Under normal use, the life of the lock body of a face recognition smart door lock can exceed 100,000 times. If it is used 10 times a day, it can be used for as long as 30 years.
