Warning Fatigue
One of the many problems facing security engineers is warning fatigue – the tendency of users who have seen too many security warnings to start ignoring the warnings altogether. Good designers think carefully about every warning they display, knowing that each added warning will dilute the warnings that were already there. Warning fatigue is a…

Reading the Broadcast Flag Rules
With the FCC apparently about to announce Broadcast Flag rules, there has been a flurry of letters to the FCC and legislators about the harm such rules would do. The Flag is clearly a bad idea. It will raise the price of digital TV decoders; and it will retard innovation in decoder design; but it…

SunnComm's Latest
SunnComm is now taking yet another position regarding Alex Halderman’s paper – that the paper is just “political activism masquerading as research”. (The quote comes from SunnComm president Peter Jacobs, responding to a question from Seth Finkelstein.)

Alex Halderman has published an interesting technical report analyzing the newest CD “copy protection” technology. Alex, who is a graduate student here in Princeton’s computer science department, also wrote the definitive paper on the previous generation of CD copy protection. Alex’s paper explains how the SunnComm technology works and why it won’t help the record…

"Hacktivism" by Artists
A debate has started over the suggestion by Harvard Law prof Charles Nesson that artists respond to file-sharing of their work with “hacktivism,” by launching targeted denial-of-service attacks on people who redistribute their work.

Story Time (Cont.)
Several readers took issue with my previous post relating anti-infringement technology to anti-cancer technology. So let me clarify what I was and wasn’t trying to say. First, I wasn’t saying that infringement is okay. It’s not. And I wasn’t trying to draw a moral equivalence between infringers and copyright owners. Remember: I analogized infringement to…
