Deniable authentication

Deniable authentication means that someone can access a system or information without evidence or proof that they ever did it. Think of it like playing hide-and-seek with your friends. If you successfully hide and your friends can't find you, you can deny that you were ever even playing the game.

With deniable authentication, someone can log into a system and do what they need to do without leaving any signs that they were ever there. This can be useful in situations where privacy and secrecy are important, such as in a spy mission or in a confidential business transaction.

However, it's important to note that deniable authentication can also be risky because it could potentially be used for malicious purposes. It's important to use it responsibly and only in situations where it's necessary to maintain confidentiality.
