APOLLOUNIONSensorNow on the market, most smartphones are equipped with fingerprint scanners. The major mobile phone manufacturers are also claiming how secure their fingerprint scanners are. But it's really safe?

The answer is not so. First of all, these fingerprint sensors are not absolutely secure. Old-fashionedcapacitive sensorWhen your hands are sweaty or wet, the fingerprint sensor is difficult to recognize correctly. If you have scratches, scars and other skin defects on your fingers, it will also reduce the accuracy of identification. In addition, how to effectively distinguish between real fingers and fake fingers is also a security loophole.

With the release of the ultrasonic fingerprint recognition sensor by Qualcomm, the above problems will be effectively solved. Security research experts have found that fingerprint images on HTC One Max and Samsung Galaxy S 250.00g phones can be easily stolen by any software that has access to users' pictures and the Internet. Although developers have made security patches, who can guarantee that there will be no such loopholes the next time a new phone is launched or an updated system is released?

Although Apple phones do a good job in this regard, because the fingerprint data is encrypted. However, many other smart phones are still quite weak on the fingerprint sensor, making it easy for some malware to steal fingerprint images from the fingerprint sensor.

Some mobile phone manufacturers use ARM TrustZone technology to protect the fingerprint data stored in the phone, so that the main operating system can not access. Unfortunately, depending on the implementation model, this technique also has drawbacks.

If someone tells you that a fingerprint is not a password and that no one can share it with others, tell them not to take it seriously. At the beginning of the new year, experts showed us how to easily steal fingerprints-remotely, as long as we can get a high-resolution photo of the victim's fingerprint. DSLR cameras or high-definition photos from magazines will do.

If the password is stolen, you can change it immediately, but the fingerprint is not so easy. What if the fingerprint is stolen? So for the current major mainstream mobile phone manufacturers advertising, you can not fully believe. Here are a few simple safety rules:

1. Don't trust any mobile phone manufacturer's commitment to the security of mobile phone fingerprints, let alone use fingerprint scanners to authorize any services involving financial transactions. If your phone is stolen, you will be at great risk. Hackers can easily copy the fingerprints on the phone shell, and then use your fingerprint permissions to buy their own. The difficulty of stealing passwords is much higher.

2. People usually use the index finger and thumb of the right hand, and hackers can easily get fingerprints from the items you touch. It is suggested to make fingerprints with the little thumb and ring finger of the left hand, reflect on the dimension and strengthen the anti-theft.

3. Because fingerprints are not enough to protect the private data in your phone. Therefore, it is suggested to install some third-party software with mobile phone encryption function, such as 360 mobile phone software and Tencent mobile phone butler. The advantage of this is that after the mobile phone is lost, the data in the mobile phone can be cleared remotely. Enhance security.
