US Cops Can't Keep License Plate Data Scans Secret Without Reason, Court Rules (theregister.co.uk)

An anonymous reader quotes a report from The Register: Police departments cannot categorically deny access to data collected through automated license plate readers, California's Supreme Court said on Thursday -- a ruling that may help privacy advocates monitor government data practices. The ACLU Foundation of Southern California and the Electronic Frontier Foundation sought to obtain some of this data in 2012 from the Los Angeles Police Department and Sheriff's Department, but the agencies refused, on the basis that investigatory data is exempt from disclosure laws. So the following year, the two advocacy groups sued, hoping to understand more about how this data hoard is handled. The LAPD, according to court documents, collects data from 1.2 million vehicles per week and retains that data for five years. The LASD captures data from 1.7 to 1.8 million vehicles per week, which it retains for two years. The ACLU contends [PDF] that indiscriminate license plate data harvesting presents a risk to civil liberties and privacy. It argues that constant monitoring has the potential to chill rights of free speech and association and that databases of license plate numbers invite institutional abuse, not to mention security risks.

    That's the crux of the problem. I'm OK with them collecting the data. I'm even OK with them holding it for a few months (2-5 years seems excessive). What I'm not OK with is them (or the public) being able to access the database willy nilly to look up any license plate they want. The system should be behind lock and key, and require a warrant before they can search for a specific license plate. Or maybe a wildcard search for a partial plate at a certain location around a certain time. Or a match search if the same plate appears at multiple locations at specific times, which spits out only the plates which match that criteria, none of the other plates.

    If the data can be anonymized until such time as it is needed in an investigation, then I don't see a problem with the longer data retention.

    But it can't be anonymized in any way that would still make it useful for investigative purposes. A plate number is an identifier. It is impossible to anonymize an identifier in such a way that it can be consistently rehashed from the original value to the same "anonymized" value every time, but in such a way that someone with access to the original value cannot effectively de-anonymize the data at will. If there's a way for the license plate readers to convert the plate number into a consistent identifier, then the police can perform the same conversion just as easily, so it isn't really anonymized from the police. If there isn't a way to do so, then it isn't useful for the police to have the anonymized data, because there's no longer any way to determine whether two "anonymized" values refer to the same car.

    And if the intent is to hash it in such a way that you can look up a specific car but can't easily see who was near a particular location, that won't prevent abuse, either, unless you don't have traffic cameras or other storage that would contain the unencrypted plate information (even for a short time). After all, to unmask a hashed plate number, all you would have to do is watch for a particular hashed plate to pop up somewhere, then look at the unhashed plates in that spot, checking each plate until you find the one that hashes to that value. Although that would be harder, it still would not require a judge to issue an order or otherwise force external oversight into the investigative process in any meaningful way, at least from a technical standpoint.

    The best you could realistically do would be to discard the complete data and store only a colliding hash in you throw away everything but the last two digits, thus allowing you to say yes or no to the question of whether a car with those last two digits was in a given area at a given time, but not which of the millions of cars with those last two digits were there. This would make it harder to use for tracking, but would also make it less useful for investigative purposes, providing only sufficient grounds for getting a judicial order to compel access to the complete (unhashed) records.

    Realistically, the options are either A. don't keep the records, or B. keep the records offline, in a vault, with a judge's order required to remove one of the tapes from the vault, and the key used to encrypt it kept in the independent custody of an antagonistic organization, e.g. the police have the tapes, but major news media outlets have control over the private key required to decrypt them, split in such a way that a certain number of outlets have to agree before you can reconstruct the entire private key.

    LOL, you can get all that information just from scanning a license plate?

    By scanning it in the right places, you can establish patterns that strongly imply those things, assuming the psychologist or cancer specialist is in a clinic dedicated to that specialty and not in a general hospital. You can also determine that your husband or wife is in a particular neighborhood on Friday nights and not at work as he or she has claimed, thus leading you to discover that your husband or wife is having an affair. You can determine whether clusters of adjacent houses won't have anyone nearby to report someone breaking in and stealing everything. (Just be sure to cover your plates a few blocks away.) And so on.

    The general public gaining access to such a database would be a privacy nightmare. And as a rule, if disclosure of information would be a big enough disaster, the right solution is to not retain the data, or where possible, to not create the data in the first place.

Its total budget should probably not be greater than and of the higher population states (which will grow to do a lot of what the feds are doing now).

    In today's America I am willing to bet that the underground and black market economies are as large as the official economies.

    Yes, if she was driving a car formerly owned by He-Man, I definitely would want to know about it. :-D

    But if you mean her car, then no, it would not be nice. It would strike me as creepy, psycho, stalker behavior. The sorts of people who want that level of access to everyone's history are often precisely the people who should not be allowed to have it. As soon as you allow someone that level of access, they will find ways to use it to manipulate and control people.

    For example, it is relatively trivial to cherry-pick data to paint unflattering pictures that will embarrass you, even if you have done nothing wrong. Between property crimes and violent crimes, a crime is reported about every ten minutes somewhere in San Francisco. If you have a car, the probability of your car being near a significant number of them approaches one by the time you have lived there for a year. So you could use this, potentially, to implicate anyone for anything.

    And that doesn't even consider whether people should have a right to privacy in their personal lives, in their medical history, etc. We have explicit laws to prevent disclosure of a person's medical history precisely because there is a good reason for a right to privacy in those areas. Yet if you have full access to plate data, you can show a pattern of someone going to an oncology center for a chemo appointment every n weeks, and suddenly you know something that you really should not have a right to know.

    And what of that bride to be? What right do you have to know who every one of her ex-boyfriends was? You could get that from plate data. Correlate which plates appeared in the same places at the same times week after week, and you now know intimate details. Oh, and that one time when she spent a couple of extended stops at an abortion clinic followed by suddenly no longer seeing that guy... well, now you know that, too.

    You definitely don't have a right to know everything about everyone—even the people closest to you. What your bride-to-be chooses to disclose to you is her decision, and hers alone. That is as it should be. The past is the past, and unless your bride-to-be poses a real risk of causing you harm in the present, you should leave it in the past. And if she does, you shouldn't be marrying her in the first place. More to the point, if you don't trust her, you shouldn't be marrying her in the first place, because either she is untrustworthy or you are untrusting, and either one will eventually lead to the marriage self destructing.
