Do smart locks work? Listen to a 27-year experience of a high-security lock industry

In the past two years, with the blowout of the smart lock market, various brands, various identification methods, and various functions of smart locks have emerged on the market. Many consumers who want to buy smart locks don’t have the ability to start with a dazzling array of products. Today, Xiao Bian asked the industry insider who had 27 years of experience in the lock industry with this question. Hear what he said?

Do smart locks work?

Lock industry experts:

It's important to use a sense of experience from the customer, easy to use, easy to use to solve some pain points in life is a very important reason to buy, but security is also one of the important considerations for the door lock. At present, there are fingerprints, human faces, irises, and veins on the market that use life identification technology to verify unlocking.

To make a comparative analysis: The first three are in vitro feature recognition, veins are in vivo feature recognition. Analyzed from the ease of use, the fingerprint advantage is not limited by the body's high and low posture, the finger activity area is relatively large, one finger can easily identify the opening of the door; face iris limited by the scope of the head activity limit, the use of experience will be a little worse . The problem that fingerprints currently have to overcome is that they are affected by the environment. The temperature is too low, the air is too dry, the fingers are dirty, there is water in the hands, and the fingers are tanned. In addition, some groups adapt to the fingerprints of children and young girls. Shallow, old, severe keratinization of fingers, long-term wear and tear of the fingerprint road; industrial workers' finger wear is also a serious group; various environmental and crowd factors will greatly reduce the customer experience brought by fingerprint recognition! Some manufacturers are not satisfied with responsibility. The reduction means of comparing the feature points will be adopted. It is extremely undesirable to increase the refusal rate to increase customer experience at the expense of safety!

Analyze from the security of biometric identification: Do not look forward to the concept of biometrics' safety and the flicker's living concept. Biometrics technology is ultimately the collection and identification of computer images, as long as they are seen by the image capture device. Images with the same biometric image, even with dynamic images, are not very complicated. So as long as your biological characteristics are stolen by someone else, counterfeiting is not a problem, so it is easy to judge whether a biometric technology is safe or not. Just look at whether this biometric feature is easily stolen by others!

Fingerprints and human faces belong to in vitro feature recognition, and the relative concealment is poor. Vein recognition is relatively obvious in terms of in vivo feature recognition. You are extremely difficult to steal my biometrics in the case of non-coordination. Even if it uses so many anti-counterfeiting technologies for Apple's mobile phones, it is still being attacked by emulation masks only for half a month. Face recognition is not suitable for access security management, and security is too low!

In summary, it is currently the best choice to choose vein recognition in the unlocking recognition mode. The popular expression is that the “key” is hidden in the blood, and you don’t need to worry about criminals to steal my characteristic information to unlock the door; because the internal features are affected by the environment It is very low, and the environment and crowd adaptability is high. The weather in the north is cold and dry. The south is hot and humid, the elderly and children are easy to use.

Do you have any good recommendations?

Lock industry experts:

I stayed in this industry for 27 years, and a family company is now able to apply finger vein recognition technology to home door locks.

The company is called Nanjing Dongwu Electric. It is a high-tech enterprise established in 1991. They have always been committed to high-security locks. They have accumulated rich experience and accumulated technology in the field of high-security locks. The products are marketed in more than 40 countries around the world. In the region, there are cooperation with 120 domestic banks. (Note)

In 2016, they launched a high-security vein lock for the mass market. This year, second-generation vein locks have also been introduced.

This Dong Fang. Shi An intravenous lock V8 uses a unique second-generation vein recognition technology: do not change your habits; pulp dirty skin serious and rapid identification; circuit design uses a financial encryption technology that can effectively prevent professional thieves The destruction. The key parts are equipped with anti-drilling plates, and the lock body's unique re-locking mechanism prevents professionals from opening violence. The switchable anti-cat's eye does not change the hand-opening habit of the handle, and can be freely switched according to the humanized demand. No threading before and after, solved the problem of fire prevention and the installation was as simple and convenient as the mechanical lock. The unique disaster recovery and perfection system has solved the anxiety that locks have problems and cannot leave home and other service personnel.

From biometrics, circuit encryption design, mechanics, and overall security solutions are enhanced; user-friendly use of functional design exceeds your imagination!
