2021-01-23A news release on the th said: because the weather was too cold, the fingerprint lock installed at home failed, and the fingerprint identification unlocking, password unlocking and remote control unlocking failed. They couldn't open the door. Then they had to borrow a hot water bag from their neighbors to cover the fingerprint lock and unlock the door.

Some netizens said that the fingerprint lock was not frozen at minus 30 degrees and minus 10 degrees in Northeast China, and the unlocking method of intelligent lock is not only fingerprint, but also password and key. They doubt the authenticity of the video.

In fact, whether the above things are true or not, only from the application stability of the two, the fingerprint recognition intelligent lock must be mature over the face recognition intelligent lock.Although face recognition technology has been applied in many fields such as security, most ordinary consumers' impression of it still stays in film and television pictures.Fingerprint identification technology has been developed for more than 20 years, and people have trusted and recognized fingerprint identification technology. With the adoption of fingerprint unlocking function in the mobile phone field, people are even more interested in fingerprint identification technology products.For the unfamiliar face recognition technology, people have to show their own appearance, and this technology has not shown more charm to the public, so people's attitude towards face recognition lock is more curious, questioning and wait-and-see.

Face recognition smart lock is a technology that allows users to fully obtain the personal information stored in the device by recognizing faces.In short, the user records his face through the camera, so that the device can memorize the face information in advance, recognize the face through the camera and unlock it.The essence of face recognition intelligent lock is nothing more than security, convenience and fashion.False rejection rate and false recognition rate are undoubtedly one of the most important indicators, which can also be called rejection rate and false recognition rate.

Face recognition technology is to recognize the input face image or video stream based on human face features.Firstly, the recognition process is to judge whether there is a face. After recognizing a face, scan the position and size of each face and the position information of each main facial organ. Then, according to these information, further extract the identity features contained in each face and compare them with known faces, so as to recognize the identity of each face.Compared with fingerprint recognition, its main advantage is that the face recognition intelligent lock can actively obtain user information without user contact.

2Years ago, the face recognition commonly used in the industry was still 2D recognition - in theory, a photo can deceive the camera.Of course, in order to eliminate this problem, many face recognition SDK developers (bat, Kuangshi, Shangtang, Yitu, green deep pupil, etc.) have launched live detection technology, allowing users to blink, shake their head, side face and other actions towards the lens to judge real people.

Therefore, 3D face technology began to popularize.Unlike the pure algorithm scheme of 2D, 3D technology depends on hardware.Through hardware capture, we can instantly judge the living body while verifying the face, which is a real biometric technology.Is that why there is a fringe on the top of the iPhone x?This is not only because there is a front camera, but also a lot of other sensors to capture users' facial expressions.

Secondly, the power consumption of face recognition lock should be one of the concerns of consumers. Ordinary fingerprint lock comes with 4 dry batteries, and the power consumption is basically only used for fingerprint recognition, so it is normal to replace the battery for about a year;The energy consumption of face recognition in obtaining face is much higher than that of fingerprint lock. At the same time, it is also necessary to enable lighting in dark occasions, or change the battery and charge frequently. Inadvertently, the power is insufficient, resulting in the inability to open the door and affecting life.

Solving the above two problems of technology and power consumption is now the top priority of the improvement and optimization of face recognition intelligent lock, because it determines whether the face recognition lock can win the trust of consumers.

In addition to "face recognition", intelligent lock can make people feel trendy temporarily. Its practicability, convenience, stability and security are far better than fingerprint lock. At the same time, fingerprint lock is also developing. For example, ultrasonic fingerprint recognition can read fingerprint information without touching each other.Therefore, in the future, face recognition lock will not pose a threat to fingerprint lock.

Baidu knows that some netizens answered questions and said that the current fingerprint identification algorithm is no longer the traditional image method on the mobile phone to unlock. Many high-end fingerprint locks are compared and identified through fingerprint feature points. This is also that the FBI identifies a person's identity through 13 feature points on a person's fingerprint. The feature point acquisition algorithm effectively solves the problems of shallow fingerprint and dirty hands,Wet hands.The advantages of high-end fingerprint lock are fast recognition and high recognition rate.Most face recognition algorithms use face space algorithm. At present, there are still many loopholes. The key point is the power consumption, which has always been a pain point of face recognition.

Face recognition is not the mainstream of intelligent lock industry.However, in the long run, with the improvement of technology maturity and the decline of cost, the popularity of face recognition in intelligent lock products will be further accelerated.Because compared with other authentication methods, face recognition is the only contactless recognition method at present, which has an absolute advantage in shaping the user experience.

At the same time, compared with fingerprint, whether optical fingerprint, capacitive fingerprint or ultrasonic fingerprint, the amount of information in face recognition verification is the largest and the probability of being cracked is relatively small.In vivo detection, compared with finger vein, face recognition module has small volume and high efficiency.However, in about three to five years, brushing your face and entering your home will become a modern consumption stereotype we are used to.

Which is the better application experience between fingerprint lock and face recognition intelligent lock?Conclusion:

Science and technology are driving the progress of society, and everything in the world is changing all the time. Nothing is invariable. The essence of the world is always forward and progress!

Although, in terms of technical maturity, the error rate and application performance of fingerprint lock must be better than that of face recognition intelligent lock at this stage, and the total consumption of fingerprint lock is also greater than that of face recognition intelligent lock.However, technology is always broken through, and the experience will be more and more advanced.In the past, when Nokia was brilliant, some people said that the physical keys of the mobile phone must be better than the touch screen. After 15 years of baptism, where can we see the mobile phone with physical keys now?

The essence of intelligent door lock technology is the same. If current intelligent lock manufacturers do not develop, produce and sell face recognition intelligent locks, human intelligent locks will only stop at fingerprint recognition intelligent locks.But is that possible?
