Business and government are similar in that they are all staffed and run by people (that is, greedy grafty nasty people). They are different in that we elect our government people and there is some oversight of the work and the results - sometimes late, and sometimes shoddy, but the oversight is there.. A business on the other hand, involves no community decision, is run as a dictatorship and there is minimal oversight (less and less every day since the 80's).
I'm not anti-business, just honest. The problems come from the people, not the organizational method. The organizational method is supposed to be a way of compensating for the problems while minimizing the bad side-effects.

And besides, not entirely true:
A: There is no "back door" implemented in TrueCrypt. However, there is a way to "reset" a TrueCrypt volume password/keyfile. After you create a volume, backup its header (select Tools -> Backup Volume Header) before you allow a non-admin user to use the volume. Note that the volume header (which is encrypted with a header key derived from a password/keyfile) contains the master key with which the volume is encrypted. Then ask the user to choose a password, and set it for him/her (Volumes -> Change Volume Password); or generate a user keyfile for him/her. Then you can allow the user to use the volume and to change the password/keyfiles without your assistance/permission. In case he/she forgets his/her password or loses his/her keyfile, you can "reset" the volume password/keyfiles to your original admin password/keyfiles by restoring the volume header (Tools -> Restore Volume Header).

During normal operation, you mount both the outer container and the hidden container using both the outer and hidden key. This enables truecrypt to see the hidden container and move around hidden data as you write to the outer container.
When you are arrested, you provide the key to the outer container, but not to the hidden one. In this mode, it's as if the hidden container doesn't exist and can of course be overwritten. There's absolutely nothing to prove that the hidden container exists, as long as you have a plausible outer container and can say "Look, this is what I was trying to hide".

Re:TrueCrypt's method is not detectable (Score:5, Insightful)
When you initialize your encrypted disk space, you tell Truecrypt how many containers you want. Say that you choose 2. When you mount your Truecrypt drive, you must always mount both containers. In this way, Truecrypt knows and can maintain integrity between the two--they won't start to overwrite or corrupt each other, because they are both known about and available. If you ever only give the first key (you can't just give the second key, as the second container is entirely within the first) then you run the risk of corrupting the second container--in fact, any write operation will probably do it.
Now you can choose more than just two containers, and the same applies. One thing I'm not sure of is whether the third container is fully within the second.
If I am sending encrypted mail using PGP, I'm using someone else's PGP key. I don't have to have a PGP key myself in order to do this. If someone else is sending me encrypted messages, they could be sending it using anyone's PGP key--it's only obviously my key if it's provable that I've read the messages. For example, Alice could encrypt a message using Bob's public key, and then send that message to Charlie in an effort to frame him. Charlie gets the junk message and deletes it, but the feds who were wiretapping Charlie come in and demand to know what was in the message. Charlie can't answer--he has no idea. So he gets 2 years in prison from the RIPA act.

Re:TrueCrypt's method is not detectable (Score:5, Interesting)
That's actually pretty much a stretch. Your 'decent' lawyer would have to give some sort of proof that there was a second partition there. Something that TrueCrypt is pretty much designed to prevent. You can easily show the existence of the first truecrypt partition - it's there in the open. You can't prove the existence of the second partition.
I'm not sure a judge will buy 'because we didn't find what we were looking for' as a reasonable showing of proof that a second partition exists, and unfortunately, that's all the proof that exists. The formatting method and the processing method result in random data covering the entire partition block, as data is written to both the shown & hidden partitions, that data changes from random to encrypted. However the whole goal of the crypto data is to make it look random.
So you have potentially 3 blocks of random data each constructed with the same randomizing algorythm. How exactly do you show where one begins & one ends? How do you even show that the 3rd block exists? The whole purpose of the hidden block is to make it almost impossible to prove the existence of that third block. You literally are more likely to brute force the key than you are to prove the existence of the hidden partition.

Don't just encrypt -- Hide! (Score:5, Insightful)
Encrypting your data and not hiding it is the same as getting a $100k super secure safe, locking your stuff in it, but leaving it in the middle of the living room. Any { law enforcement agency / criminal gang / anyone with more resources and more muscles that you } will just force you to give them the key. In other words, they see the super secure safe and automatically assume there must be at least $1M in there and then they force you to give them the key. The govt will cite all kinds of stupid idiotic laws, the criminals will start cutting of the fingers (yours or your loved ones').
The solution is to use something like steganography and hide the data such that nobody even will suspect anything. The best secrets are the ones that are not even known to exist.
If the adversary is convinced that you do have the data and knows the data type, then create a similar but fake data set to be substituted for the real one.

You never used Truecrypt eh? It's not a zip file. It acts as a virtual hard drive partition that can be mounted as a drive.
When you create the volume it generates random bits throughout the virtual partition. You can copy whatever files you want onto the virtual partition, the rest of it is random noise. You may or may not choose to have additional hidden encrypted partitions within that noise. Adding up the size of know files tells you nothing about what may or may not lurk in the rest of the space on the virtual partition.

Just because the possibility exists, the authority in question might ask for something he cannot prove isn't there. If you have nothing to give, this leads to the problem of lying to authorities to give them what they think they want, when you've already given them what they asked for and it proves you innocent.

That said, I believe that there *is* a time and place where this sort of activity counts as reasonable search & seizure. Say the cops get a warrant to search your house, and you have a safe, and you say, "gee, officer, I have *no* idea how that safe got mounted behind that picture," nobody will believe you and you'll get subpoena'd for the combo. Encryption keys shouldn't be treated any differently from a combination to a safe. If there's a reasonable suspicion for evidence to be hidden somewhere, the cops have a duty to search it.

There are already laws against perverting the course of justice and hiding or tampering with evidence. The difference is that they have to show some evidence that there's relevant evidence in the safe. If RIPA applied to safes, they'd just have to show you have a safe and won't open it. They only have to have a 'reasonable belief' that you can open it, and having it on your property, or on property in any way associated with you is enough to meet that criteria. That's sufficient to carry up to 5 years in jail, regardless of what's actually in the safe, or what they can demonstrate might be in the safe.
The law is intended to allow them to put suspected terrorists and pedophiles in jail, even when they have no evidence they did anything illegal, and don't have the capability to brute force their encrypted files, and don't have sufficient grounds to charge them with something else. As we can see, once the british justice system get an 'anti-terrorism' power, it immediately becomes a tool to use against everyone.

Its funny. Animal right activists always wage their violent protests and hate campaigns against scientists and business people. Where are the hate campaigns against slaughterhouse workers and farmers? Much if not most of the practices of these people are at least on the same level as animal research.
The fact is this. Violent animal rights activists are not committing these actions because they care about animals. They are committing these actions because they enjoy committing these actions. They enjoy harassing and threatening push over scientists and businessmen. They enjoy vandalism, petty crime and shouting people down. They enjoy it, it's that simple.
These people are middle and upper class thugs who have latched onto animal rights as an excuse to engage in violence. They need an excuse because their upbringings will not allow them to simply engage in it randomly.
Activists would never attempt any of their antics outside a slaughterhouse, because they would be quickly intimidated by the altogether more straightforward meat workers. Can you imagine what would happen if a violent animal rights protester spat on a slaughterhouse worker, or shoted abuse to them outside their home? I'd pay to see the results.
Vandalism, threats, pretending to be a terrorist movement, designating "Legitimate Target" (LOL), it's how they get their kicks. It's a giant LARP for these people, except that real people doing real research on real problems are getting seriously hurt by it. They're having their fun, and the animals have nothing to do with it.
Violent animal rights workers are simply bullies who pick soft targets, i.e. scientists, who they proceed to harass and abuse to make themselves feel better. They are not a legitimate movement. They are not a cause. They don't have a point of view. They are a rich kids' street gang, too afraid to actually walk the streets.
I don't approve of animals suffering needlessly. I find experiments like this one [wikipedia.org], or this [wikipedia.org] contemptible, and if I was a research lab director, I wouldn't have approved them. I would however have approved less severe variations of such experiments. Ones in which while I knew animals might suffer somewhat, that they would not suffer needlessly or excessively. Animal research is necessary, and I defend its use, but only under the condition that the animals are treated with respect, and that their suffering and sacrifice is acknowledged. It's funny how more "primitive" cultures seem to follow such rules as a matter of fact, but our more "modern" scientists have to be reminded of it.
We need science, but we also need our consciences. Animal rights activists have neither.
