Next time you’re on a conference call, you might want to reconsider typing on your computer while your microphone is on.
UK researchers successfully trained artificial intelligence to decode keystrokes on conference calls, meaning the AI can determine what you’re typing, even if your screen and keyboard aren’t on display during the call, Hacker News reports.
The research notes that while people often hide their screens or keyboards when typing a password, they often don’t do anything to obfuscate the sound of their keyboard. But AI can capture essentially anything you type on your computer, including sensitive emails or documents.
According to the paper, AI trained by keystrokes recorded by a nearby phone achieved a 95% accuracy. When trained on keystrokes recorded by Zoom, it had a 93% accuracy.
Even when the AI wasn’t able to perfectly determine what was typed, it would often only be off by one key, making it easy for potential hackers to circumvent the error.
