Smart Door Lock Solving Technology
2013, iPhone5s equipped with fingerprint identification turned out when the amazing time. IOS8 released in 2015, Apple’s HomeKet smart home software project turned out. At that time there is a domestic thinking, if the fingerprint recognition technology can be used in the smart door lock on the smart home of the hub, it may play an important role. Technology is the core, intelligence is the trend. From the domestic and international smart home wave of technical reserves point of view, family lock from the smart and fingerprint this dream has become a reality.
Traditional door locks in the same dummy, technical ideas or a way out
What kind of security door to achieve the role of anti-theft it? An anti-theft door for many years in the industry, anti-theft security of the two basic components is the door and anti-theft lock. In terms of anti-theft performance, qualified anti-theft security door body thickness should generally be more than 20 mm, the door body to be covered with reinforced steel, and to fill the filling, so that the front and rear panels organically connected together to enhance The overall strength of the door.
Even so, the thickness of the steel plate is still not the focus of anti-theft door. Because the road a little high foot tall, mechanical anti-theft door lock can not stop cat’s eye break, wire picklock and other “clever” as the times continue to improve. It is so, the theft of the door was still pry the accident is still repeated.
More noteworthy is that the security door is not not be prized open, but in a certain period of time not to be forced open. National standards are provided, Class A security door anti-theft time of not less than 30 minutes, B anti-theft door anti-theft time of not less than 15 minutes, C-level anti-theft door anti-theft time of not less than 10 minutes, Ding anti-theft door anti-theft time of not less than 6 minutes.
In this case, the traditional mechanical lock seems to have suffered a life and death crisis. With the further development of intelligent tide, home intelligent and convenient is the mainstream of life, intelligent buildings, smart home, intelligent transportation and so on in the intelligent gradually penetrate into people’s lives, intelligent door lock is almost a sure thing.
Three different solutions, forward-looking conservative
Driven by the tide of intelligence, at home and abroad have been thinking about the new way out of the lock. Based on the network and Bluetooth smart door locks, fingerprint gates based on fingerprint recognition and even face recognition, iris recognition of the door lock has become a choice. These three solutions, based on the network and Bluetooth smart door lock is relatively conservative, and fingerprint, face, iris program is relatively radical. The three major solutions to talk about which is stronger, in fact, all manufacturers in the technical and practical aspects of their own thinking, have a strong rationality.
1, based on WIFI, GSM, Bluetooth network
Currently based on WIFI, GSM network or Bluetooth smart door lock is the mainstream choice at home and abroad. This is the most basic solution for smart door locks.
The birth of a residential door lock in the United States has these features. This lock is based on the data network, can support iOS and Android mobile phone system, and also with the use of smart watches. Users in the open door, do not need to like the traditional door locks that need mechanical keys, as long as the phone near the door lock on it. If the user forget to carry a cell phone or cell phone happens to be no electricity, the door is also equipped with a touch Peng screen, the user can be set according to the previous 4-8 Arabic alphanumeric code to unlock.
But some of the domestic smart door lock more focus on safety, so it is relatively conservative. In order to prevent the phone was stolen brush or hackers break the situation, these locks still need to choose the traditional key lock, but the key with smart chips, each time the door will be through the WeChat, SMS way to remind the user. Similar to it, domestic solutions also use the GSM data network approach, because the GSM data network can take the encryption route, compared to WIFI and other programs more secure. In order to ensure security, the program also has a separate background and the cloud, to connect with the phone to help users through the phone in time to accept and at any time to check the family access door information, and remote alarm.
American lock manufacturers of a variety of products under the idea is more conservative. In order to ensure absolute security, its door locks do not even go GSM network, but directly through the Bluetooth connection to unlock the phone. According to its solution, users can use iOS or Android applications to create an account, through the Bluetooth pairing, you can achieve automatic lock door or unlock the operation. Because there is no use of WIFI standards, so do not need to connect to the Internet, it will avoid the Internet attack and crack.
2, based on fingerprint identification of biological characteristics
Fingerprint lock is the use of human biometric fingerprints for identity security identification certification to open the door, with high-tech digital image processing, biometric and DSP algorithms and other technologies, in line with modern security requirements of a new generation of access control system. At present, the fingerprint lock has been widely used in government agencies, military bases, banks, senior apartments and other places need absolute safety and privacy. Old Wang Xie Tang Qian Yan, flying into the homes of ordinary people. In the past, the use of fingerprints in related secret places now with some manufacturers of technology research is also gradually used in the ordinary people living.
Foreign well-known brands have begun to enter this area, trying to want a share. The old company launched a direct campaign to launch their own products. The new product is equipped with a doorbell and a door bolt, as well as a camera and a microphone. Users can directly see from the home visitors who, even when no one at home when you can leave a message.
As with traditional smart locks, you can remotely unlock and lock through app apps that come with Android, iOS, and Windows. There are four ways to enter the smart door locks, respectively, through the application, key card, pin or keyboard or even the user’s fingerprint. In fact, the domestic smart lock is also based on fingerprint identification of the door lock on the exploration.
Fingerprint recognition is the biggest obstacle to the fingerprint of the biological characteristics of a crack, it is a life-long crack. Apple, Meizu and other models using fingerprint recognition are in fact fingerprint information blocked in a mobile phone inside the encrypted area, never docking with the clouds. Part of the domestic solution is with the Swedish fingerprint identification chip manufacturers “FPC” cooperation, development and production of biometric components and technology. It is understood that the fingerprint recognition technology and Huawei Mate7 and millet 5 and other mobile phones to provide fingerprint core technology at the same level.
3, face recognition and iris recognition
With Alibaba, Tencent and other financial products in the use of face recognition, this technology will rise to a new height. Data show that in 2012 China’s face recognition industry market size of about 1.67 billion yuan, is expected by 2015, China’s face recognition industry market size will reach 7.5 billion, the future potential market size will exceed 100 billion. The concept of face recognition companies are good technology, Hanwang technology.
Compared with face recognition technology, iris recognition and intravenous authentication and other technical theory is more scientific and reliable, with a low error rate, biological characteristics is not easy to damage, difficult to forge, copy the advantages. Especially iris recognition, has been hailed as the most accurate and safest way of biometrics.
For this smart door lock in the future use of face recognition, iris recognition and intravenous authentication technology is also the date can be expected. And even such technology even more convenient than fingerprints, can not be copied.
With the rapid development of intelligent terminal equipment and mobile Internet industry, in the information security, Internet finance and social entertainment, as a cutting-edge technology biology will usher in a huge space for development.
Although the current have a hypocritical password, burglar alarm, smart home and other functions, anti-theft play a multiple protection, but the current development of smart locks is still in the immature state, part of the logic of the product there are problems. Although the technical tough, but this product idea is clearly a big problem, and people to prevent the stranger’s psychological out of tune. The future of intelligent door locks or in the smart home and networking, which led to the entire smart home system in the chemical type of comprehensive response.
