A piece of orange peel, can open the phone fingerprint lock in seconds?

Recently, an article entitled "A piece of orange peel can open your mobile phone fingerprint lock and can also transfer money" has attracted a lot of attention. It is mentioned that for mobile phones that require fingerprint verification, some simple processing methods can be used, and anyone's fingerprints can be unlocked, even with a piece of orange peel.

The reporter contacted the publisher of this information, a technician from a technology company in Suzhou. In the lab, the technician demonstrated the cracking process.

It is understood that the relevant departments of the Ministry of Industry and Information Technology and the General Administration of Quality Supervision, Inspection and Quarantine have been involved in the investigation.

Fingerprint touch button cracks anyone can unlock

Not long ago, Xiao Xu from Anhui, the phone accidentally fell to the ground, causing cracks in the fingerprint touch button. What surprised him was that other people could use his fingerprint to unlock his mobile phone. Not only that, but some payment applications that require fingerprint recognition can be used for verification and use.

Subsequently, Xiao Xu immediately contacted the mobile phone manufacturer, and the merchant blocked the fingerprint function for Xiao Xu.

After knowing this, a technician from a technology company in Suzhou simulated the pattern of the fingerprint of the fingerprint of the mobile phone in the laboratory. After many experiments, they found that even if the phone is not damaged, after some processing, the fingerprint can still be cracked. Locks, even with a piece of orange peel, can be verified.

Fingerprint stickers can also unlock the payment

In the laboratory, the technician first recorded the fingerprint of his left thumb with his mobile phone. At this time, only the thumb of the left hand of the technician can be unlocked.

After that, the technicians carried out some processing, including attaching a fingerprint sticker to the fingerprint key, etc., and the reporter who did not input the fingerprint before, even unlocked the boot.

Subsequently, the technicians tested the mobile phones of some mainstream brand models on the market one by one. The reporters successfully unlocked the mobile phones with their own fingerprints without first entering the fingerprints.

In the use of fingerprint verification payment, after the technicians perform some simple operations on the reporter's mobile phone, in addition to the reporter himself can use the fingerprint transfer, the replacement of the fingerprint with the longan, orange peel or even napkins can also be verified.

The technician said that the fingerprint touch key crack pattern was simulated in the laboratory and many experiments were carried out. The key to crack fingerprint verification was the pattern on the fingerprint touch key.

The technician takes a small piece of tape or a popular fingerprint on the market, and the back is coated with a conductive pen to form a pattern, which is attached to the fingerprint verification part of the mobile phone. As long as the fingerprint of the owner touches the tape or the fingerprint sticker, after successfully unlocking the boot several times, others can boot at will.

The technician said that the crack itself will form some patterns on the sensor, and after attaching the film (adhesive or fingerprint), the conductive medium on the film will also form a certain pattern on the sensor, because this pattern is in front of the finger. It will replace the fingerprint. The fingerprint sensor receives these patterns and eventually authenticates them.

The technician believes that the information received by the fingerprint sensor, including the conductive coating on the fingerprint, is not exactly the fingerprint of the owner's finger. When performing fingerprint comparison, as long as some of the information is the same, it can be verified. Therefore, as long as it is processed, other people's fingerprints can also be verified.

â–¡ Tips

It is best to check the touch key before fingerprint verification.

Similar security risks have been found in some electronic locks that use fingerprint verification for laptops and security doors.

Experts suggest that before using fingerprint verification, it is best to check whether the touch keys are attached with foreign objects or patterns. If the fingerprint touch key is not damaged or attached to the fingerprint, it can be used normally without worry.

In addition, if the fingerprint touch button of the mobile phone accidentally breaks, you can try to find out if other fingers can be unlocked successfully. If the unlocking is successful, there is a loophole.
