This trick only affects machines left screen-locked or in sleep or hibernation mode, and it is a lab technique not an operational police technique.. If you can pull the power before getting arrested then it isn't applicable. If you leave your machine protected by a screen saver then you are already fucked anyway.

"We almost recommended TrueCrypt which works on several platforms. However, in light of this research, only Pretty Good Privacy (PGP) by Philip Zimmerman gets our nod, especially if you’re travelling"

PGP is the best encryption publically available but current draconian laws punish you for failing to reveal the key and the files are identifiable. A cheap and cheerful workaround is to encrypt a file using PGP and then dump that inside a TrueCrypt folder inside another TrueCrypt folder. The law can still force you to open the first folder, but they cannot identify a folder within a folder and so cannot force you to admit to even the existence of any other nestled files, let alone their key. So you are reasonably safe from both criminals and police alike.

what a bullshit. Zimmerman's PGP is closed source and nobody knows how exactly it works. nobody who has a glimpse of understanding what security means recommends that.

that you "have to give the key to you data" is a MYTH. NOBODY, i repeat NOBODY has to help to generate eveidence against him/herself. the law often quoted targets witnesses and clarifies that giving the key to evidence is enforced, the same as they HAVE to give evidence as witnesses.

The source code for the PGP algorithm is available online though? There are plenty of open source versions of it if you need it... and Mr Z did release the original source code.

Yeah, read this and weep . The fact is there is no fifth addmentment to the UK consitution that allows us to stay silent - we don't even have a written constitution so everything they do is 'legal'. It's not democracy, it is not justice, but it is reality. First they came for the animal rights activists..
