This artificial intelligence (AI) could represent a threat to the privacy of users .
A team of researchers from Cornell University in the United States has developed an Artificial Intelligence capable of identifying passwords by analyzing the sound of the keys pressed on a computer.
According to Tom’s Hardware, “By recording keystrokes to train the model, they were able to predict what was typed on the keyboard with up to 95% accuracy. This dropped to 93% when Zoom was used to train the system.” .
However, this Artificial Intelligence does not operate with any random keyboard, as it requires to be trained for a particular keyboard with information about which character is associated with each keystroke. Additionally, this training can be done via a microphone or remotely using the Zoom app to record the sound of keystrokes.
Nearly 100% accurate for password stealing
At the project exhibit, the research team used a MacBook Pro computer to test artificial intelligence .
Tom’s Hardware mentions that they “individually pressed 36 keys 25 times each. This set the stage for the AI model to identify which character was associated with which keypress sound,” taking into account that the waveforms generated by the recording differed sufficiently to allow precise recognition of each key.
For the low-noise tactile keyboards, the team achieved a hit rate of between 64% and 40% (although it would be feasible to use software to generate white noise to increase the accuracy of the percentage).
Danger in sight?
This AI has the ability to record everything it perceives to identify sensitive content, such as confidential messages, bank details, personal information or credit card numbers, among others. However, to prevent such threats, users are advised to replace the conventional keyboard with one that does not generate noise.
