US Appeals Court Upholds Suspect's Right To Refuse Decryption

An anonymous reader writes "The U.S. 11th Circuit Court of Appeals has found that forcing a suspect to decrypt his hard drive when the government did not already know what it contained would violate his 5th Amendment rights. According to Orin Kerr of the Volohk Conspiracy, 'the court's analysis (PDF) isn't inconsistent with Boucher and Fricosu, the two district court cases on 5th Amendment limits on decryption. In both of those prior cases, the district courts merely held on the facts of the case that the testimony was a foregone conclusion.'"

He has one computer in his home, and the cops are reasonably sure that said porn was accessed and stored at that physical location only. They order him to decrypt his hard drive, because they know it has evidence of his illegal porn habits. He replies, "No it doesn't. It has other stuff. Stuff you don't know about. You can't see it."

    Now, they could say that they know for certain that he's a lying sack of crap and force him to decrypt it anyway. No child porn evidence, but he's be embezzling from his company, according to what they find. Now what?

However, in the United States, searches can be with a warrant issued "upon probable cause, supported by Oath or affirmation, and particularly describing the place to be searched, and the persons or things to be seized." Allegations can be supported by Oath, e.g. several friends and family members say they saw child porn on your laptop. Allegations can be supported by affirmation, e.g. they set up a sting operation whereby they do, in fact, know that at one time a computer in your house had downloaded child porn. But being very certain that it was downloaded onto a machine in the house just isn't the same as knowing on what machine and by whom. It also isn't the same thing as knowing it is still there.

    I know that legally the government enjoys the presumption of trust, but this is as close to self-incrimination as it can get.

    It also doesn't answer the question of what happens if, during their examination of the decrypted drive, they 'discover' other information that could lead to other charges. At least in the example of the rotting smell from the garage, if it turns out to be your dog, do they have the right to dig up the foundation to try and find a human body also? Or would the goverment then have to ask for a new warrant? In the cse of data, would they be compelled to ask for a new warrant it they 'happen' to notice evidence of unrelated crimes.

    Actually the real question for me is still a Fifth Amendment one. If they drag you into court and ask you about the rotting corpose in the garage, you can still sit there mute and refuse to answer, and there may be penalties for that, but you cannot so easily be compelled to incriminate yourself.

    Decrypting your data is a different thing, and it is virtually impossible for the government to claim they can look ONLY for the data they seek, and ignore all else. It's another thing to say they are looking in the garage for a corpse, and be able to avoid looking in the trunk of car parked on the street, despite walking by it repeatedly as they swarm over the garage.

    Sorry, but I think we need much more protections. My phone has enough information on it to give law enforcement access to things they should need more than one warrant for, and discovery they should not be able to make while searching for something else.

    No it isn't. To continue your analogy of a dead body, they can get a warrant that allows them to search your garage. If you don't open it for them, they then can break in and conduct their search. To apply this to the laptop scenario, the government indeed had a search warrant for the laptop and it was turned over by the defendant. She, in no way, can be compelled to unlock it or do anything else to it but in retrospect, the government would have the right to break into it. In trying to force the defendant to open it, the government has stated that they can't or won't break into it for fear of damaging possible evidence. That's their problem, not the defendant's problem.

    [IANAL] I agree w/ the appeals court's decision here. Forcing the defendant to unlock and/or decrypt her laptop would be forcing her to provide evidence against herself thus violating her 5th amendment rights.

    There are two problems with this analogy: Doors can be picked and destroyed. Picking a lock or destroying a door would not destroy the evidence/property that the door was protecting.

    A better -- but still not perfect -- analogy is a safe (as another user pointed out earlier). Assume a perfectly unbreakable safe, the government would need you to provide the combination to the safe in order to gain access to the documents. IANAL, but telling the government a combination is generally not something that they can use against you. The government would have to prove that the safe belonged to you and only you through some other method.

    An encryption key is slightly different as the passphrase could be "I have a ponzi scheme and the contents of this safe prove it". I would assume that the government could not use this phrase against you. But they sure can use the contents of the decrypted files.

    All cynicism aside, we as a People need to find a way to allow the government to prosecute real criminals but also protect John Q. Citizen. I think the compromise that the police know that the drive contains specific information (e.g. they saw a specific kiddy porn picture) and then forcing the suspect to provide the decryption key is a good one. However, requiring a decryption key as a condition of me flying, driving, or doing anything else would be an intrusion.
