After entering the fingerprint or password in the fingerprint lock, the lock handle does not respond, so you can only use the key to open the door. I don't know why.

After entering autumn and winter, the weather is getting colder and colder and the air is getting drier, especially in the morning and evening. At this time, the skin on the surface of our fingers will become very dry, and the dry skin surface is very unfavorable for the collection of fingerprint images. If the image is not clear, the features of the fingerprint cannot be extracted naturally, so the fingerprint is insensitive.

Some people mistakenly think that the fingerprint lock is broken, but it is not. Solving this situation is actually very simple. Before entering the fingerprint, you can put your finger on your mouth to make it moist, or rub some hand cream to make your finger moist, which can generally solve the problem that your finger can't open the door because of the dry fingerprint.

2. The hands are not cleaned, and there are colored oil stains on the fingerprints, which is not conducive to the collection of fingerprint images. If the image is not clear, the characteristics of the fingerprint cannot be extracted naturally, which leads to the fingerprint being unrecognizable; This situation is also easy to solve, just wash your hands.

3. Finger injury or serious fingerprint wear leads to blurred fingerprints, and the fingerprint lock cannot identify fingerprints; At this time, we need to take fingerprints again, then click Register, use the registered fingerprints to enter, and then delete the registered ones. In addition, at ordinary times, one of us can record more fingerprints of several fingers. If one finger fingerprint is blurred, we can try more fingerprints.

4. The fingerprint lock has been used for a long time, and the battery equipped with the fingerprint lock is dead, resulting in the fingerprint lock not working normally; The problem of battery exhaustion is easy to solve, just replace the battery.

Offscreen fingerprint unlocking has become the new favorite of many mobile phone manufacturers, but is this technology really safe while realizing the second unlocking? Tencent Security Xuanwu Lab demonstrated the "residue reuse" vulnerability that affects the touch screen to unlock Android devices. The reporter saw that security researchers can let anyone unlock the off-screen fingerprints of mobile phones through ordinary cards.

Tencent Security Xuanwu Lab explained that the current off-screen fingerprint unlocking function is to capture the user's fingerprint image by using optical technology. By cheating with reflector, the fingerprint traces left on the screen can be used to make the fingerprint sensor think that the owner of the mobile phone is using fingerprint verification.

In addition, on GeekPwn 20 18, the AMC team successfully demonstrated the challenge of cracking private photo albums of mobile phones. Taking advantage of the vulnerability of the mobile phone operating system, the team can call other components with higher permissions by installing malicious apps in the mobile phone, thus bypassing the authentication of private photo albums.

The player also explained that this kind of cracking is a loophole based on the operation of the mobile phone, and even if the album password is longer and more complicated, it cannot be resisted.

People's network-a piece of paper opens the fingerprint lock of mobile phone in seconds.
