Mobile phone fingerprint recognition is considered to be a lock screen technology with a relatively high security factor. However, it has recently been reported that mobile phone fingerprint recognition can be arbitrarily unlocked, saying that good security is no longer trusted.
Recently, a Suzhou company reported to the Ministry of Industry and Information Technology, the Ministry of Public Security, the Office of the Ministry of Communications, the People's Bank of China and other four departments, they found a shock hole in the fingerprint unlocking of mobile phones - just use a piece of transparent tape + a conductive pen, you can Second break the mobile phone fingerprint identification system, easy to boot, and even pay.
Why can I unlock it arbitrarily?The principle is that the fingerprint recognition of the mobile phone does not need to be 100% identical, and it is usually only about 20%. When the fingerprint button of the mobile phone is attached with the tape that moves the hands and feet, when the owner uses the finger button, the mobile phone generates a new fingerprint pattern through the sensor, which is equal to the conductive liquid pattern, plus the owner fingerprint. The smartphone remembers the new fingerprint with the conductive liquid pattern. At this time, using any finger, or even any tool that just presses the fingerprint button to unlock the fingerprint, a new fingerprint with the same conductive liquid pattern will be formed, and the mobile phone will unlock and release as long as the conductive liquid pattern is recognized.
The company staff said that this cracking method is available for any brand of mobile phone. “The phone can be unlocked by others, so the privacy and secrets of the phone owner can be seen at a glance.â€
Of course, privacy leaks are only part of it. Especially nowadays, mobile payment has become a trend. WeChat and Alipay, including some bank mobile phone accounts, have used fingerprints to pay and transfer money. When people who are ill-intentioned exploit this vulnerability, this will face a security risk of property damage.
There is no absolute security and confidentiality in the world.Nothing in the world is perfect, without loopholes and malpractices, such as military-grade passwords, various digital passwords, biometric passwords—whether fingerprints, irises, or faces—can be Cracked. After all, these high-tech technologies are all designed and manufactured by us. It is understandable that there are loopholes. The key is whether the loopholes can be identified, remedied, or used by the bad guys.
Therefore, for this fingerprint identification vulnerability, it is recommended that: 1. In daily life, don't let your mobile phone leave your line of sight, basically it will not give opportunities for people with ulterior motives. 2. Use important numbers or Chinese characters for more important documents and data. 3. Lost the mobile phone: immediately report the mobile phone number, freeze the mobile online banking, unlink the WeChat, Alipay and other related accounts, and notify the mobile phone contacts to avoid secondary losses.
