Extension lecture introducing steganography (hidden messages). Security via obscurity. Hidden messages in book Godel Escher Bach. In film Starship Troopers. In games. In cryptography. In teaching. Digital watermarking. SETI. Are we in a simulation?

Extension lectures are for first year computing students at UNSW. The topics covered are non-examinable, students attend only if they are interested. Richard generally raises more questions than he answers.

  • Shouldn't the book be "The Codebreaker" by David Khan.. And not "The Code Book"..??

    I am confused..

  • Yes Kahn's brilliant book is "The Codebreakers" and is the best book on the history and principles of cryptography I've had the pleasure to read. The Code Book is another popular book on codes but i've not read it, quite a few of my students like it however. A book I can strong recommend is "Decrypted Secrets" by FL Bauer, and of course Applied Cryptography by Bruce Schneier is a brilliant introduction to the field since the second world war.

  • Oh. This is cool. Secret messages.

  • Nice guy :D

  • put in "Theory and Practice of Cryptography November, 28 2007" to youtube. There's a google lecture with EXACTLY the same content and in the order that is displayed here.. i wonder is this common order to talk about things in or did someone copy off someone

  • @Orione hahaha me too :D

  • Very good job, from one instructor to another.  You have class, and the ability to simply complicated subjects. Only one regret, wish I had you as an instructor. :)

  • How can we test if we are in a simulation?

  • does anyone know the date of when this lecture was? I want to reference in in my essay

  • I wish my teachers would be like this guy. It makes lessons interesting

  • I like how the smiley face game was not only about the finished drawing, but the way it was drew as well.
