In this podcast you'll hear a presentation by Frank Stajano of the University of Cambridge. In it he discusses seven principles for systems security derived from understanding scam victims.
He argues that by understanding the recurring behavioural patterns of victims that hustlers have learned to exploit, we can create systems that are more resistant to fraud.
Frank plays three videos in the talk. With two of them you can get by with the audio alone, but the first one has a significant visual component. The good news is I found the video on Youtube, and I've linked to it here.
You'll hear me, during this presentation, say something along the lines of "check out the video now" so you can pause the mp3 and watch the video. Sounds a bit involved, I know, but it's the only way I could think of to bring this presentation to you.
Here's the YouTube link again.
