Electronic smart door locks have many new high-tech functions. Whether these new functions are safe has become one of the most concerned issues for consumers.

Fingerprint unlock function

It is understood that fingerprints are very unique among the biological characteristics of the human body. Only theoretically, there is a possibility of coincidence, with a probability of one in 15 billion. And fingerprint recognition algorithm software has been a mature industry after nearly two decades of development. Therefore, from the perspective of security identification, the fingerprint identification function of the electronic smart door lock is safe. At the same time, for misrecognition (false recognition rate) and rejection recognition (rejection rate), the country has national standards, industry standards and group standards specifically for smart door locks. As long as they meet the standards, their security is trustworthy.

Moreover, fingerprints are not easy to be copied. At present, there is a saying that fingerprints can be copied with a small piece of material, but it is actually unreliable. If you want to copy a fingerprint, the premise is that the person being copied takes the initiative and cooperates many times. If the fingerprint is handed over to the copying party for multiple copies, it is only possible to succeed. The fingerprints left on water cups, tea cups and other items in life are basically impossible to be copied completely.

However, experts suggest that during the process of using the fingerprint lock, if a foreign object is found in the fingerprint reading area, it should be removed immediately and the fingerprint should be re-registered.

Password unlock function

There are two types of password security issues. One is the length and strength of the password. Electronic smart door locks are generally six-digit or more passwords, and bank cards are also six-digit passwords. Practice has proved that the probability of being cracked is extremely low. Moreover, the smart door lock also has an anti-violent cracking mechanism. When the password is entered incorrectly a certain number of times, the smart door lock will be locked to prevent multiple cracking. Therefore, judging from these two points, the password of the electronic smart door lock is safe.

The other is the problem of password protection, such as the problem of virtual passwords and passwords being stolen. At present, the length of virtual passwords should not exceed 50 digits. The smart door lock companies of domestic mainstream brands generally have 32 digits in length, which is safe. As for the problem of password theft, relevant experts suggest that the password should be changed regularly and the password should be self-protected. Do not use obvious information such as simple birthday or ID number as the unlock password to prevent the password from being stolen. On the whole, the password function of the electronic smart door lock is also safe.

Swipe to unlock function

Many media have reported security incidents related to the card swiping function before, but the fact is that the prerequisite for copying is to obtain the card that can be unlocked, otherwise it cannot be copied. Therefore, as long as you protect the security of your card, you can greatly prevent the card from being copied.

Electronic smart door lock companies have developed a copy-preventing CPU card through several years of technology research and development and a large amount of investment. It has begun to be used in some products and will be promoted in the industry on a large scale in the future.

Internet function

The networking functions of electronic smart door locks can generally be divided into remote information interaction (locking, closing information, etc.), unlocking condition control (setting the unlocking time, duration, etc.), multi-terminal linkage (security product support), smart home linkage (TV, Several major functional categories such as air-conditioning, lights and other products, household products linkage).

The security of the Internet function is determined by three aspects: the information security of the lock, the information security of the transmission, and the information security of other terminals (control terminal, cloud, etc.), which constitute a comprehensive security system. The door locks, whether they are electronic smart door locks or mechanical door locks, are locks that protect safety. Therefore, the safety of electronic smart door locks is the safety of the lock first. At present, most manufacturers have designed security management software and security chips. Wait for the hardware to solve the information security problem to ensure the security of the lock.

Remote opening function

To ensure the security of Internet functions, on the one hand, we must start with technology to ensure the information security of the lock, and on the other hand, we must start with physical protection. Therefore, unless in a specific place or under the premise of security, it is not recommended to use the remote direct opening function. If remote opening is required, the remote authorized opening function can be used to ensure the safety of the door lock.
