The Failing Right of Laptop Privacy

davidwr writes "Wired has an interesting editorial on laptop searches and seizures. It raises some interesting issues, including employee rights against police searches in the workplace, routine vs. non-routine searches at ports of entry, and police use of unrelated data found in a database search. The article ends saying: 'Of course, there's a chance that the courts will not recognize the different scope of privacy interests at stake in computer searches, or will not be adept at crafting a rule that gives enough leeway and guidance to law enforcement, while also protecting privacy. At that point, the Constitution may fail us, and we will have to turn to Congress to create rules that are better adapted for the information age.'"

      That's what a steganographic filesystem is for: plausible deniability. You have multiple layers of data encryption, none of which know about the lower layers, each of which stores data in the free space left behind by the upper layer. They ask you for the password, you provide the password to financial records at the first encrypted layer. For that matter, you could have an unencrypted layer on top so that there's no proof that any encrypted data even exists. In the unlikely event that they find the crypto tool, though, you have financial records at the first encrypted level. Say that there's nothing else, but under duress, admit to a second level with something a little more embarrassing (e.g. your porn collection). Keep anything that has to be kept secret at the third level.

      There are two big problems, though: 1. Writes to the upper layer overwrite data at the lower layers, so the redundancy at the lower layers is pretty crucial to avoid data loss, and even then, beyond a certain point, you'll start losing data. 2. All the implementations I've seen out there are Linux-only (or at best UNIX/Linux), which makes them less than useless for most of the general public.

      TrueCrypt allows for hidden volumes (i.e. encrypted areas within encrypted areas) and it's a windows program. They claim it's not possible to detect the hidden volumes, but I have to take their word for it.

      Actually, they say it is possible to detect hidden volumes a few ways, one being if you're using a journaled filesystem on the host device. It will be possible to see changes to hard disk sectors that the directory will say are not being used by files. So the solution is not to format the source disk as NTFS in a Windows case and use FAT32 or something like that.

    So keep your sensitive personal data on a server at home, where the protections against warrantless search and seizure are more clearly defined, and take with you on your laptop only what you need. Also there are all sorts of ways to remotely access your at-home data securely (DNS Forwarder/VPN, etc). That way your data is there when YOU need it and not sitting on your portable when you are crossing borders or sitting in your employer's office.
    I have made it quite clear to contractors that their laptops will be subject to scrutiny prior to their being permitted to access our corporate LAN, as well there my be periodic spot-checks, especially if I suspect that a laptop might have become infected with something nasty.

    It doesn't matter if you're worried about a snooping government, script kiddies, nosy roommates or family members, or anybody else you don't want looking at your data. In this day and age, there really is no substitute for encryption, and there's also really no excuse to not be using it, given the amount of options (many of them free, as in speech and beer) available today. There's no reason to leave things like tax returns, sensitive work projects, etc. sitting out in the open.

    One of the best things that I've done recently is to wipe and randomize a 40-gig partition on one of my drives and set up a 256-bit AES-encrypted ext3 filesystem. Unless I enter my lengthy passphrase, there is no way to mount the volume, much less look at its contents. Barring some unforseen weakness in AES, this is now data that nobody but me will ever see (unless I do something silly like forget to unmount it).

    It is, in many ways, a brave new world, but people need to know that there are things they can do to protect themselves. This, of course, is not news to the Slashdot crowd, but it is something that the less-clueful public needs to hear about.

    Well, out of the Bill of Rights, Amendments 1, 7, and 8 make absolute statements prohibiting certain acts of Congress (e.g. "Congress shall make no law..."); Amendments 2, 4, 9, and 10 refer to "the people" which could mean all people or 'the people of the United States' (i.e., citizens); and Amendments 5 and 6 use language referring to "no person" or "the accused," which can only mean that they apply to all people, not just citizens. (And for completeness, Amendment 3 would only be relevant for people who owned property in the US.)

    The relevant Amendment in this situation, the 4th, is one of those that refer to "the people:"

    The right of the people to be secure in their persons, houses, papers, and effects, against unreasonable searches and seizures, shall not be violated, and no warrants shall issue, but upon probable cause, supported by oath or affirmation, and particularly describing the place to be searched, and the persons or things to be seized.

    Keep all your actual, working data on a USB Key. For super-extra security, don't stick the USB key in your PC when it's hooked up to the Internet.

    My laptop is really just a shell; it's got an OS, and a ton of music and games on it's HD, but not a single text file or anything personal. Even my browser history is shredded each time I close it. So if I loose my laptop/have it stolen/etc., I'm really just losing hardware and the time it takes to put my OS and music on a new one.

    It's worked great for me - and allowed me to eek life out of otherwise dying laptops. When you use a USB key (and back it up on a 2nd key, as I do, every so often), you are protected against hardware failure. If your PC dies, you take your key, go elsewhere, and continue working.

    Don't store data on your laptop if you take it anywhere out of your house. It's just good sense.

            If they say its just a routine inspection let them look, don't let them open files
            If they want to see a file ask for the warrant
            If they insist ask (don't) demand to see a supervisor

    4 - Be nice, calm, and ask the supervisor to witness
            Any search (with understanding you are under protest) as there is no warrant.
            Ask the supervisor for a full accounting of all files opened/accessed prior to boot/power on

  13. Another Perspective on Personal Data by McLuhanesque · · Score: 2, Interesting

    The overwhelming response of the sysadmins, and many others, is, it's the employer's computer, therefore everything on it is available to the employer (ie. no expectation of privacy as confirmed by 9th Circuit). But there is another perspective that might be reasonably argued (Of course, IANAL; I am a media theory researcher and prof).

    If we consider that electronic stuff (hardware, software and data) as containers within containers, the hardware might be owned by the employer, and the employer might have a right to see what containers are placed on the hardware. However, many of those containers (files) might contain so-called intellectual property that belongs to the person herself. The employer has no right to that (leaving aside, for the moment, contracts in which the individual stupidly gives all IP rights to the employer, even for private, non-work-related, non-compensated creations). The mere fact of physical location does not give the employer the right of unwarranted search. For example, the person's purse happens to be located in the desk drawer of the employer-supplied desk, within the employer's office. The employer does not have the right to search the purse, nor take possession of its contents. By analogy, I would argue that the content of personal data files (not necessarily the wrapper that is the file structure itself) is off-limits to the employer.

    In short: the employer has the right (according to court ruling) to see the files on their property, but not necessarily the file content. The courts have not distinguished among respective ownerships of the hardware, the data structures, and the data contents. This distinction is something that will eventually be tested in court, I expect.

    Like other posters, I agree that the employer could demand immediate return of the laptop and the individual would lose all of her personal information, and therefore the person must assume that risk of loss, encryption or no encryption. And I use my own laptop for my work - the employer does not have the right to access my machine. If they want my work (which they do) they agree to my terms. Every so often I hear the dire warning of the IT department about not providing me support. But then again, I've had occasion to fix some of the messes on other users' computers that were "supported" by the IT department.

    The second admendment does not say firearms are limited to a militia, it specifically states the right of the people to keep and bear Arms, shall not be infringed. People have the right. It make perfect sense when you consider the Founding Fathers were concerned about a tyrannical government, when only the government has firearms and not the people, it invites the government to become tyrannical. that's what happened in 1930's NAZI Germany, in the 1980s Iran after the overthrow of the Shah, and I heard the same thing happened in Rwanda in the early 1990s.

    I'd almost argue this. After all, there's no reason a person needs a main battle tank, or a series of cruise missiles, sitting in their backyard.

    Can you "bear" a main battle tank or a cruise missile? No.

    "Arms", in historical context, meant guns that were carried by a soldier. The term was understood to be distinct from "cannon", big-ass guns that were not something a man would "keep and bear".

    If a weapon is something that an infantryman would carry into battle, it falls within the rightful scope of the right to keep and bear arms recognized in Amendment II, within the corollary to right of self- and community-defense - the right of access to defensive tools.

    If it's a WMD, if its mere presence creates a danger to people nearby (like if my neighbor was keeping anthrax spores or large amounts of TNT in his shed), the RKBA is not infringed by regulating it. Except, for the fact, that a peashooter isn't going to do it these days.

    Iraq. Afghanistan (US and USSR experiences). Palestine. Vietnam. Connect the dots and see the picture: groups with "pea shooters" can mount a significant resistance against an vastly better armed occupier.

    What you've got here is a deliberate attempt to muddy the waters of searching laptops... they're arguing is that you shouldn't worry about your work laptop being searched because it's not yours, and usually work disallows you from putting private data on there anyway. There's two problems with that. First, if it's a work laptop the TSA is searching, YOU are not the owner, especially if you are following the rules, what would you do with an encrypted volume or such work put on there to keep your email or company financial data private if your laptop was stolen? The second fallacy is that the TSA is saying if it's not your "work" laptop you somehow shouldn't be traveling with personal private data... that's the biggest form of bullshit ever. It's the whole "you incriminate yourself" by brining private material into a public place that's going on more and more lately... and that is 10 ways from wrong.. The founding fathers clearly knew what they wrote, in 1776 you would take crates of personal stuff along on trips.. often guys like George Washington or Ben Franklin were away from their homes on travel for MONTHS at a time... personal property is just that...personal... demanding that it remain personal is not some "license" to perform a search because you ask they not look there... that's exactly what unreasonable search is.. especially when the search is unrequested in a public place.
