In the modern world, it's hard to find someone who doesn't use the internet. Almost everyone has a smartphone or computer and uses a keyboard for typing. This study aims to investigate the potential risks of data leakage through keyboards. Each keystroke produces a unique sound and pattern of vibration. It can be difficult for a human to accurately distinguish between similar sounds, and even more so for vibrations generated by a keyboard. However, technology is constantly evolving, and microphones and accelerometers are getting more sensitive and accurate. Modern sensors can detect small fluctuations that humans can't catch. Some attention will be given to how to protect against devices that use accelerometers to carry out attacks.
