However, they also shift the threat. If Authoritarianstan police know that CryptoToolX deletes messages after a while, they are likely to feel more justified in further interrogating the suspect, knowing that if the messages aren't there now, it's likely that they were there earlier. It's hard to discuss those features not because they aren't cool and useful (they are!) but because they make it difficult to maintain a sense of priority. Measuring how a feature will help, how it'll change the threat and whether it will eclipse attention from greater threats and concerns is kind of trick AFAICT. > > Certainly this is not a be all and and all, but does seem like a > potentially valuable feature based on my own broad observation of "fools" > amongst many activist and journalist groups. > > Brian > > > On Tue, Feb 5, 2013 at 11:11 AM, Jacob Appelbaum <[email protected]>wrote: > >> Brian Conley: >> > Apparently Silent Circle is also proposing such a feature now. >> >> Such a feature makes sense when we consider the pervasive world of >> targeted attacks.
