Latest Episode: Rise of the Hackers

Sep 24, 2014 Season 42 Episode 2 watch on (Paid)

From PBS and NOVA - Our lives are going digital. We shop, bank and even date online. Computers hold our treasured photographs, private emails, and all of our personal information. This data is precious — and cybercriminals want it. Now, NOVA goes behind the scenes of the fast-paced world of cryptography to meet the scientists battling to keep our data safe. They are experts in extreme physics, math and a new field called "ultra-paranoid computing," all working to forge unbreakable codes and build ultra-fast computers. From the two men who uncovered the world's most advanced cyber weapon to the computer expert who worked out how to hack into cash machines and scientists who believe they can store a password in your unconscious brain, NOVA investigates how a new global geek squad is harnessing cutting-edge science — all to stay one step ahead of the hackers.
