In today's digital world, protecting personal and sensitive information is crucial. A new threat has emerged called acoustic side-channel attacks on keyboards, which exploit unintentional acoustic signals generated while typing to decipher keystrokes. This survey paper provides a thorough analysis of this danger, including attack strategies, methods, and their consequences. We explore key recognition techniques, the different acoustic features used, and performance metrics for evaluation. This survey is an essential resource for researchers, practitioners, and security experts to protect against acoustic side-channel attacks on keyboards.
