Where is the security of fingerprint locks? Isn t a fingerprint lock very secure?

The combination of mechanics and identification technology is key.

Any electronic part has the possibility of error or missed the time to change the battery, relatively speaking, the mechanical part should be more stable, keep the mechanical key of the lock as a backup way to open the door at home, you can open the door in time and facilitate maintenance when the electronic part of the door lock is out of the problem. What would you do if there was a fire in your home, or if a thief damaged the electronic part of your door lock because he didn't pick the lock? Don't covet the so-called non-porous psychologically, and ignore the way back, choose the kind of door lock without a mechanical key, but the assembled mechanical lock should reach the atomic lock above the B-level anti-theft, etc., the design of the lock cover has been alarmed, and dare to do it again.

At present, fingerprint authentication is very mature, there is no need to worry about its security, of course, absolute security does not exist, you should try to buy products from large manufacturers such as Probuck, Samsung, Central Control, Wendatong are more professional manufacturers in the industry.

Because a person's fingerprint is unique, not even a fake one. I read a news today, the above is about a nanny stealing the master's house, this is a typical case, you can search for fingerprint lock industry news to see.

Due to the uniqueness of a person's fingerprint, theoretically, a fingerprint lock can only be opened by a designated person.

Using the only fingerprint recognition technology, it is very convenient to open the door, and the fingerprint lock in my house opens the door as long as the finger is put down.

Compared with traditional mechanical locks, fingerprint locks are indeed more secure, but there are still some drawbacks.

One. Basic concepts.

Fingerprint lock is a kind of intelligent lock with the fingerprint of the human finger as the identification carrier and means, which is the perfect crystallization of computer information technology, electronic technology, mechanical technology and modern hardware technology. Fingerprint locks are generally composed of two parts: electronic identification and control, and mechanical linkage system. The uniqueness and non-replication of the fingerprint of the living trapped experience determine that the fingerprint lock is the most secure lock among all locks at present.

In addition to fingerprint identification, fingerprint locks shall be equipped with emergency mechanical keys according to the provisions of the Ministry of Public Security.

Two. Function.

Fingerprint opening, password opening, emergency key opening, and now the way of opening with a card has been added, so that consumers can trust and choose fingerprint locks more. There are many manufacturers who integrate doorbells, voice prompts, networking, alarms and other functions on their products. At first glance, users seem to have a lot of features, which seems to save other unnecessary costs, which may be tempting.

Personally, I think this is an irresponsible design of the manufacturer, and the main function of the fingerprint lock is security and convenience.

Three. The core components of the fingerprint lock: the motherboard, the Likai ruler (semi-automatic lock), the fingerprint collector, the password technology, the microprocessor (CPU) watch, the smart emergency key, the power supply equipment (battery charger, transformer, etc.).

The possible security risks of fingerprint locks are as follows:

1. The fingerprint recognition rate needs to be improved, mainly because some people cannot use the fingerprint lock, usually 1%-5% of people cannot use the fingerprint lock, or they need to be identified multiple times to pass. However, some manufacturers are beginning to make finger vein locks to make up for the shortcomings of fingerprint recognition.

If the fingerprint lock can be convenient for more than 98% of people to use, it is quite good. Any product has its own flaws, and the vast majority of people can use it, and that's fine.

2. The battery life is different. The number of high-energy-consuming functions, the scientificity of circuit design, the rationality of leakage protection, the number of users and the frequency are all important factors affecting power supply.

In practical application, the life of many manufacturers' fingerprint locks is less than half a year, and the fingerprint lock does not prompt the user to replace the battery, which often causes the user to be turned away and causes unnecessary trouble.

3. The stability of the fingerprint lock is not high, the fingerprint lock is a device combined with a motor, the quality of the lock cylinder, the scientificity and rationality of the design of the first circuit of the electric shed, will affect the stability of the fingerprint lock. When consumers buy products, it is best to choose fingerprint locks produced by professional manufacturers.

Fingerprint locks may be convenient to use, but it doesn't mean that they are absolutely safe, because these are easy things for unlocking masters. Like the fingerprint lock I use at home, it is purely for convenience, because my husband and I often forget to bring the key, and it is very troublesome to keep changing the lock. <>

Judging from the fact that we often forget to bring the key and have to change the lock repeatedly, every time we invite the master to unlock it, it will be easy to unlock the ordinary lock at home. Then the fingerprint lock was used in the house. But it's still easy to watch the master change the lock!

For thieves, it shouldn't be difficult! Since you have done this business, you must have a certain amount of technicality.

Our family bought a new house in August last year and changed the fingerprint lock. Later, because my mother-in-law was pregnant, she often came to take care of her, so she entered her mother-in-law's fingerprints, and then my father-in-law and brother-in-law also came to the house one after another, so I entered these people's fingerprints. It means that there are already five people in the family who have fingerprints.

There are certain hidden dangers in these. <>

You must know that the fingerprint lock is not only as simple as entering the fingerprint to unlock, but also can enter the password. Then there were two times when we were not at home, and two relatives came to the house and needed to pick up something, so we told them the fingerprint lock code in a hurry, and then something happened...

My husband's cousin is a very dishonest person, because once there was a power outage in his house and there was a baby, and my husband and we were not at home, so he kindly told his wife the password and let them rest in our house. As a result, once my husband's cousin's sister and his ** saw that they were at my house, so they told us about it. It's really a very angry thing, and it's scary to think about it!

Without our consent, without our knowledge, his cousin brought someone to my house! It wasn't until later that my husband questioned him that he confessed. Because his cousin is in the intermediary business, we don't sell houses, and we don't take strangers to our house to see the house without our consent.

When I think about it, I am very prepared. The first thing I did when I got home was to quickly check the soft at home, the real estate certificate and other things. To be honest, we may not be able to see some things very clearly, my husband and I are more careless people, and we don't care about how much cash and other things are stored at home.

But people with bad character like this really don't want to be in contact with them in the future.

Therefore, families who are ready to change fingerprint locks should still consider security from many aspects. If a relative like us asks you for a password and is embarrassed to refuse, but if you only have the key, there is no such hidden danger. Fingerprints are sometimes easy to lose.

There are a lot of problems anyway.
