In Cryptography, a blind signature, as introduced by David Chaum, is a form of Digital signature in which the content of a message is disguised ( blinded Undeniable signatures are a form of Digital signature invented by David Chaum and Hans van Antwerpen in 1989. An anonymous remailer is a server computer which receives messages with embedded instructions on where to send them next and which forwards them without revealing where Digital mixes (also known as mix networks) were invented by David Chaum in the early 1980s Onion routing is a technique for anonymous communication over a Computer network. Digital mixes (also known as mix networks) were invented by David Chaum in the early 1980s The dining cryptographers protocol is a method of anonymous communication Generally considered the father of anonymous communications David Chaum first proposed a system for anonymous email in 1981 Bruce Schneier (born 15 January 1963) is an American Cryptographer, Computer security specialist and Writer.
