Indistinguishability obfuscation (IO) is like a special cloak that makes your digital information invisible. It works by using complicated math to make it so that when a hacker looks at your data, they can't tell what it is. Even if they know what kind of data it is, they can't tell who it belongs to or what it's supposed to do. IO provides a way to protect your digital information so that hackers can't access it and misuse it.
