Fingerprint authentication door lock, which is constantly cracked by mysterious women at the exhibition fair | China

Become a small black box of social problems. By skipping high-voltage electromagnetic waves, the circuit of the electronic door lock is broken and the key is disabled.

The password era is coming to an end, and fingerprint authentication door locks are popular.

　The era of passwords is drawing to a close. Many smartphones support fingerprint authentication and face authentication. When you have to enter a password, you can do fingerprint / face authentication, and enter the password automatically. If it is biological authentication, because it will not be forgotten, so there is no need to make password notes, hidden somewhere such a pre-era thing.

　The physical password = the key also fades away. Many cars have become electronic locks, which can unlock the door and start the engine with a button.

　Whether it is the door of the home, or fingerprint authentication things are beginning to increase. You don't need to take the key with you. You don't have to worry about losing it. According to the fingerprint authentication method, when the door is closed, it can be locked automatically. This is because if you use the previous key method for automatic locking, there will be frequent accidents of being locked without a key.

　In China, fingerprint-certified door locks also began to sell well about three years ago. When opening the door, hold the doorknob no matter what. It is convenient and well received to configure the type of fingerprint sensor in the holding position.

　On EC sites such as Taobao, prices range from 30, 000 yen to 50, 000 yen, which is by no means cheap, but one of the good ones. It is reported that Haier, Panasonic, Samsung and other manufacturers have also joined in, there have been more than 30 manufacturers bidding.

　However, in May 2018, a major event took place at the Ninth China International door Industry Expo held in Yongkang City, Zhejiang Province.

"I can break your door lock in three seconds."

　The fair is a so-called door-related exhibition fair, which is exhibited and demonstrated by many manufacturers. There appeared a young woman who claimed to be the king. Princess Shi visited the booth showing fingerprint authentication door locks and declared: "I can break your door locks in three seconds."

　Then, take out the black box-like device from the bag, put it on the electronic door lock and open the switch, and the electronic door lock is released. Princess Shi visited the booth showing electronic locks, cracked a total of eight electronic locks, and left the venue. It is not yet known who this woman is, what background she has, and what purpose she is doing.

　The device she uses is not uncommon, commonly known as the "little black box", which is very famous for the people on that road. The principle is very simple, which is to emit high-frequency electromagnetic waves. The electromagnetic wave flows through the high voltage current in the circuit inside the electronic door lock, initializing or destroying the circuit. Therefore, it can attack not only the lock of fingerprint authentication, but also all the locks of password, IC card, face authentication and so on.

　EC website "Taobao" also used the price of several hundred yuan as the "electronic door lock security testing device." At present, it has been criticized by all parties and has been designated as a banned product.

The experimental image of the small black box reported by Chinese online media Pear Video.

　In the case of electronic door locks, in order to eliminate the influence of external electromagnetic waves, metal covers should be used to cover the circuit, but many products are not simple. According to Princess history, the simplicity of the industry will be revealed.

　Manufacturers quickly try to deal with this small black box attack, adding electromagnetic wave defense shielding, but it is not all manufacturers. Among the weak and small manufacturers who take cheap as the selling point, although there is a "no problem" explanation, there are actually many places that have not done anything.

　Consumers can't try it themselves. The small black boxes are not available because they are banned from display on many EC sites. Moreover, if tried, the circuit may also be damaged.

In the end, the actual damage occurred and new problems were found.

China's Yantai radio and television station broadcast surveillance video using small black boxes to capture intruders in empty nests.

　Among them, the harm of using the empty nest of this small black box has been reported.

　The China Consumer Association attached great importance to this issue and tested 29 kinds of electronic door locks, the results of which were made public on May 5. It turned out that there were 28 kinds of electronic door locks to deal with, only one was unlocked by a small black box attack.

Part of the test results made public by the China Consumer Association. It only quotes the products of manufacturers that are also familiar in Japan.

　This time, however, a loophole has been found from another angle. Especially in the electronic lock of the card mode, 90% of the products can simply copy the card information.

　In addition, the national "General Technical conditions for Lock Safety" stipulates the strength of the key Bello part, but among the 29 products, only 12 products have passed the standard. It also provides for an alarm when an external force is applied in an attempt to destroy it, but this is only available in 15 of the 29 products.

Choose products that pass safety standards

　As a best-selling product, many Chinese families use electronic door locks, but the safety of the products is still in the future. Electronic door locks, including fingerprint verification, have been sold on the EC website in Japan. Some of them are Chinese products tailored for Japan. In Japan, with the support of the Police Agency, the Ministry of Land, Transport and the Ministry of economy, Trade and Industry, standards for spare parts of anti-theft buildings have been established, allowing qualified products to use a unified logo. If you want to buy a fingerprint-certified electronic door lock, we recommend that you seek a product that meets this marked standard.

The CP mark has been removed from the anti-theft building parts of the anti-theft standard.
