AI guesses passwords by analyzing keyboard sounds
British researchers have developed a new data-stealing technique that relies on decoding passwords from the sound of keys being pressed on a keyboard.
Will our passwords be useless soon? A group of British academics has developed a powerful algorithm that can crack access codes with the sound of fingers pressing a keyboard, according to reports. phoneandroid . In their study, labeledAcoustic side channel attack on keyboards based on deep learning The researchers state that the AI will be 95% reliable.
To find out the access key, you just need to register a person typing his secret code into the smartphone’s microphone. Once the sounds are captured, the algorithm transcribes the sound information into text.
Great adaptability
For researchers, this post is meant to warn about the vulnerability of personal data. “The wide spread of acoustic emissions from keyboards not only makes them an easily accessible means of attack, but also a very effective means of attack.They write. During its design, a database of tab noises was fed to the algorithm. It can now decode all types of keyboards, including touchpads.
Despite this troubling note, the system does have an Achilles’ heel: the Shift key. The academics report that the AI does not realize when the user releases this button. For maximum security, it is advised to change the lowercase and uppercase letters when designing a password.
