80% OF SMARTPHONES CAN UNLOCK WITH FAKE FINGERPRINTS
Fingerprint recognition is a biological model that is very common on current smartphones. But it is not safe!
This ratio is based on 20 attempts made by researchers who created fake fingerprint devices. ‘This level of success rate means that we have a very high probability of unlocking any of the tested devices before it falls back into the pin unlocking,’ the researchers said.
In addition, the study also pointed out that the most susceptible devices to fake fingerprints are padlocks, such as fingerprint authentication for iPhone 8, MacBook Pro 2018 and Samsung Galaxy S10, with a success rate of over 90%. The reason for this is that one of the core logic of fingerprint unlocking is to guess the fingerprint you have entered.
Interestingly, the Samsung Galaxy A70 has 0 success rates so that the fake fingerprint could be blocked. ‘Our fake fingerprints did not work on the Samsung A70. But the authentication rate is far lower, including on the real fingerprint than on the other devices.’
For this situation, the researchers bluntly said that no technology can be truly safe. The iteration of technology means that there is no 100% absolute security. But security issues have always been escalating offensive and defensive confrontation. So the design of security systems has never been a single point of dependence. And the more important issue is how we prevent it.
