BTP (Blind Signature Protocol)

The Blind Signature Protocol (BTP) is a cryptographic method allowing a person to get a signature on a digital message from someone else without revealing the message's content. Think of it like endorsing a document without seeing what it says. This process ensures privacy and anonymity while still verifying authenticity. It's commonly used in secure voting, digital cash, and privacy-preserving authentication systems, enabling trust without exposing sensitive information.
