Is the fingerprint unlock of the phone safe, is the fingerprint lock safe

Fingerprint unlock function, the operation method is as follows:

1.Settings - Personal - Lock Screen & Security - Screen Lock Type - Fingerprint;

2.Follow the prompts to cover your finger over the home key, lift your finger, and repeat the process. Move your finger slightly up and down between each attempt until 100% fingerprint is captured, then enter at least 6 characters with at least 1 letter and 1 number as a backup password.

3.Once you've set up your fingerprint, you'll need to select the notification option to show notifications on your lock screen. After three incorrect fingerprint verifications, you can only enter an alternate password to unlock it.

If you need to log out: Settings - Lock screen and security - Fingerprint - Unlock with fingerprint or backup password - Click on the top right corner - select the fingerprint you want to log out - Remove.

Is fingerprint unlocking for phone really safe? It's not too late to know now, so remind your family as soon as possible.

Not very safe.

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.

Manufacturers usually indicate that the battery life of the fingerprint lock can reach one year, in practical application, the life of the fingerprint lock of many manufacturers 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, causing 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 circuit design will affect the stability of the fingerprint lock. When consumers buy products, it is best to choose fingerprint locks produced by professional manufacturers.

Basic Functions of Fingerprint Lock:

1) It can be used for multiple people to open the door with fingerprints (there are often more than one or two people in a home or office), and the product quality should be stable and the performance should be good.

2) You can open the door with different permissions (it is impossible for the head of the household to have the same door opening management authority as the nanny and cleaning tools).

3) You can freely increase or decrease the fingerprint of the door opening (the nanny can easily remove her fingerprints when she leaves).

4) Have a query record function (you can check the door record at any time, sometimes it can become a key evidence, generally with a display screen).

5) Appropriate password function (after all, the fingerprint part is the electronic part may be bad, and the householder can use the password to open the door in temporary circumstances), try not to choose a product that highlights the password function too much, after all, the password is not as secure as the fingerprint. There are usually two types: 4 keys and 12 buttons.

6) Be sure to have a mechanical key, which is a backup way to open the door, like airplanes and automobiles, although they have automatic control status, but still retain the manual control part, which is a safety consideration.

On the whole, fingerprint locks have higher security than traditional locks. But it is not completely safe, and there are the following risks: First, the fingerprint lock avoids the possibility of losing the key and being copied.

Everyone's fingerprint is unique and difficult to copy, so you don't need to worry about the risk of the door lock being illegally opened due to the theft of the key. Secondly, when the ordinary lock is unlocked, it is necessary to visually confirm the lock hole and insert the key, and the fingerprint lock only needs to touch the fingerprint identification area, which is more convenient and fast, and also avoids the difficulty of unlocking in the dark environment. However, fingerprint locks also face certain security risks:

First, fingerprint information can be stolen and copied by hackers. In recent years, 3D printing technology has progressed, and it has been possible to reproduce the fingerprints of ** and other carriers. If the fingerprint information is stolen, it may be used to illegally open the fingerprint lock.

Secondly, the fingerprint recognition rate of some fingerprint lock products is not too high, and there is still a certain misopening rate and missing opening rate. This also increases the risk of being cracked by Imperial Pei. Thirdly, the sensitivity of the fingerprint lead disassembly and identification module of the fingerprint lock that has been used for many years will decrease, resulting in a longer opening time and aggravated misopening, which also affects its safety factor.

Finally, any electronic product has a positive lifespan, and fingerprint locks for long-term use are no exception. However, after the expiration of the life of electronic products, their security will be significantly reduced and they can be easily cracked, which requires users to replace their fingerprint locks regularly. So, overall, fingerprint locks are more secure than traditional locks, but they are not 100% safe.

Be aware of its security, regularly maintain and check the fingerprint lock, and avoid losses caused by security breaches. If it is not necessary, it is not recommended that fingerprint locks be used to store **value items. To achieve both convenience and security, this is where the use of fingerprint locks needs to be weighed.

A phone's fingerprint unlock is not 100% secure for the following reasons:

While each person's fingerprint is unique, researchers at New York University and Michigan State University have found that local features are generally similar between the two fingerprints, making fingerprint-based security systems on mobile phones or other devices much more fragile than they might think.

Researchers speculate that there may be enough similarity between the fingerprint areas of different people to create fake "super fingerprints" that fool the phone's fingerprint sensor.

The security level of the mobile phone fingerprint lock is not high.

The nine-square grid graphics have the lowest security level.

Fingerprint face brushing. Password (numeric).

Password (number + letter).

Password (numbers + letters + symbols).

The security level is gradually increased from top to bottom.

Of course, the above combination will have a higher level of security.

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.

1. Fingerprints are protruding lines on the epidermis. Although fingerprints are available to everyone, they are different, and fingerprint recognition is a kind of biometrics, which is a very safe and convenient way to identify;

2. Although fingerprints may be copied, they are safe enough for mobile phones, and if biometrics are used for bank cards and other higher security levels in the future, technologies such as iris recognition can be used to prevent copying;

3. The mobile phone fingerprint is enough for the protection of ordinary users' mobile phones, if you want higher protection, you can use face recognition or iris recognition.
