back to article Good luck deleting someone's private info from a trained neural network – it's likely to bork the whole thing

AI systems have weird memories. The machines desperately cling onto the data they’ve been trained on, making it difficult to delete bits of it. In fact, they often have to be completely retrained from scratch with the newer, smaller dataset. That’s no good in an age where individuals can request their personal data be removed …

  1. Teiwaz Silver badge

    The cops will be scrambling to get their biometrics on one of these post haste.

    Then they'll be able to claim they can't delete anthing it as it would impact their systems.

    1. TechnicalBen Silver badge

      I doubt most AI systems would work that way. The actual trained model probably does not contain the data, just weights relevant to some of the data.

      A bit like knowing a persons (you) supplied data and has black hair and green eyes... you can train an AI on that, but it won't know *you* are the one data point that had green eyes and black hair, because probably hundreds or thousands of other data points match that.

      Likewise, just pumping fingerprints into an AI model will tell you about fingerprints in general, not an individual's prints.

      However, it is still your data, and you could revoke access to it.

      1. Lee D Silver badge

        Unfortunately, you generally have no way of knowing how its been trained, even if you trained it.

        If you train by, say, genetic algorithms - it's quite possible that there's a mirror of your data in the trained network and it flags "success" as "John Smith was a success and this guy's data also looks like the John Smith data which I have taken upon myself to copy inside me".

        Maybe not intentionally but that's the problem - you have no idea what it's training itself on, what changes that makes to itself (could be a statistic, could be wholesale copying of the input data), or how to untrain / delete that part.

        Good luck proving in a court of law that the thing *doesn't* contain John Smith's personal information, especially if you've been copying it around your entire company... whoops! So Mr John Smith's address has been visible inside the trained neural net and you've given that to millions of people as part of your amazing AI product? Oh dear!

        These things really are as unreliable, untrainable, uncontrollable and as stupid as they sound.

        1. TechnicalBen Silver badge

          True. But I was not arguing from the legal definition (I backed that as being a requirement to retrain the model, because it is still your data), but from a practicality one.

          I've no worries about AI trained models with my data being backwards engineered, because it's rather extremely difficult. I'm more worried about the original sources still being around!

            "I've no worries about AI trained models with my data being backwards engineered, because it's rather extremely difficult. I'm more worried about the original sources still being around!"

            I agree, I'm not worried about the possibility that my data can be extracted from the model, and worrying about the original data existing is much more relevant.

            However, I also don't want my data to be used to train these systems from a purely ethical/philosophical stance. I am deeply concerned that these systems are increasingly being used for purposes that I think are harmful to everyone, and don't want to do anything that will help in their development, including contributing data.

            1. Message From A Self-Destructing Turnip

              I wouldn't worry too much about the ethical side of things, a nice man, one of the richest in the world, recently donated £150m to Oxford university to set up a new Institute for Ethics in AI. This should ensure there are no major issues for anybody (or AI) to worry about.

        2. Mike Moyle Silver badge

          "These things really are as unreliable, untrainable, uncontrollable and as stupid as they sound."

          So, basically, just like people.

          “Deletion is difficult because most machine learning models are complex black boxes so it is not clear how a data point or a set of data point is really being used,” James Zou, an assistant professor of biomedical data science at Stanford University, told The Register.

          Presumably, then, it's just like I have no idea WHY my mind seems to think that it's important that I keep the theme songs for Stingray and Fireball XL-5 in my data set. Apparently, though, it's really, REALLY important that I do and I have to assume that forcing that information OUT of storage would result in permanent damage to my personal program.

          We may be backing into actual machine intelligence and won't know that we've achieved it until the AI in question intermittently starts saying "Why can't I get that <random, useless bit of data> out of my head?!!?"

          1. I.Geller Bronze badge

            Being trained using dictionary definitions computer can accurately determine parts of speech for each word and build the correct patterns, and begin to understand you. That is, computer can stop being a calculator and start thinking. This is your only chance to force information OUT of storage.

            At the same time the quality of dictionary definitions is incredibly important! The more accurately they explain each word of each pattern the higher the chance that the computer will understand both its data and you, and delete what is not right.

            Without the dictionary definitions you can get a calculator and not AI, the comp won't know what should stay and what must go.

    2. asmblah

      I don't see how any results obtained as the output of a process that cannot be fully understood would hold up in court in the first place. But I suppose it would be useful as a way to demonstrate "probable cause" for warrants and such where they'd find the evidence used to make the case. The idea of a black box being part of the legal system worries me almost as much as the untold number of fallible humans also involved.

    By the time it's ingrained and encoded into a deep learning net...

    is it still identifiable private info? And as the laws requiring such mechanisms for deletion apply to all filing systems, agnostic of the physical medium, electronic, paper or otherwise, does this also apply to people's brains? You'd have to develop some form of amnesia drug, and be sure it had no side effects.

      > is it still identifiable private info?

      This was my question. To take an example, Bob is gay, and has HIV. That's pretty sensitive information.

      However, the relevant trained healthcare model will simply weigh the sexuality as a factor against HIV infection. In simplistic terms, the inclusion of Bob's data may push the model's link between those two facts from 20.1 to 20.2. Bob's statistics affect the model's behaviour slightly, but there is no way you could ask the model if Bob is gay - it simply doesn't know or care.

      Obviously if the training dataset is retained, that's a completely different story - but I can't see how personally identifiable information could be gleaned about a single subject from a true "black box" model.

        In your example there is actually no need for Bob to be personally identifiable so his name/ID should not even be part of the input.

        I think this is where this all should start: if it is painful to remove personal data and will deliver a ginormous fine when it doesn't happen, maybe it's better not to use data that can identify an individual.

        Key is, however, that fines are at GDPR levels of pain, not the usual "give me the change in your pockets and we're even" sort of fines that are the norm in the US.

        Re: By the time it's ingrained and encoded into a deep learning net...

        Black box algorithms do something with their data. Some of it, they keep. The question is whether it's possible to retrieve any of it. If, for example, patient name was used in the training set and given to the program, there is a good chance it has done something with that data. Maybe it identifies that people named Bob are more likely to have certain health conditions than other names. If you provided it with more information about Bob, it might be able to predict more information. Of course, a good AI developer wouldn't include patient name, as that's an invitation to pollute the data and has historically proven problematic*. But people do do it sometimes and it could therefore be a privacy risk.

        *For example, an algorithm trained on medical data to determine the likelihood of a patient having cancer was given the name of the hospital where the patient was receiving treatment. The algorithm was able to determine that patients staying at hospitals with "cancer center" in them were more likely to have or develop cancer. This made the algorithm next to useless, but it also increased the accuracy rate and if we know one thing about AI companies, they like good accuracy rates.

      Re: By the time it's ingrained and encoded into a deep learning net...

      To quote GDPR Article 4(2): ‘processing’ means any operation or set of operations which is performed on personal data or on sets of personal data, whether or not by automated means, such as collection, recording, organisation, structuring, storage, adaptation or alteration, retrieval, consultation, use, disclosure by transmission, dissemination or otherwise making available, alignment or combination, restriction, erasure or destruction;

      So strictly, retaining information about persons in one's memory could be construed as processing. But practically, I believe the interpretation would be narrower - constrained by "use", insofar as information merely remembered can not of itself affect the rights and freedoms of the person remembered unless some action is taken that makes use of the information. Thus the act of making use of the remembered information would be the processing.

  4. revenant Silver badge

    An interesting problem.

    I suspect that in practice there won't be any easy solutions, which leads me to conclude that AIs should not be trained using data that is subject to the GDPR.

    What they need is realistic, but fake, data. Obviously that would be more expensive than just lifting real-life data, but here's a thought : why not train an AI to generate bespoke fake data sets?

    1. Pascal Monett Silver badge

      Re: realistic, but fake, data

      That's an interesting idea, but how do you ensure that said fake data is realistic enough to train on ?

      If you take real data and tweak it, is it still representative of reality within acceptable margins ? What is the impact of training a statistical analysis machine on wrong data, hoping to get right answers ?

      I mean, we know a mentat could do it, but we don't have mentats yet, we only have statistics and, by rule of thumb, if you put in bad numbers, you're not going to get good results however much you try to convince yourself and everyone that you're working with "AI".

      1. revenant Silver badge

        Re: realistic, but fake, data

        Fair points. You would have to be able to analyse the output and conclude that the fake data is statistically identical to the real data. Of course, it might not need an AI to do the fake data generation - depending on how well you understand the source data population, and how good your statistical analysis skills are.

        Maybe it would all be to much, but I reckon any company that can devise a generalised fake data generator, converting a customer's real data into clean and GDPR (or whatever)-compliant data, might find it to be a very profitable venture.

      How can you even be sure that there is or is not information in the AI which is relevant to an individual? And even more worryingly how can you be certain that you fake data does not create relationships which seem to identify individuals. After all, if the data is realistic then it must mimic reality.

    Not a real issue

    Firstly you have to have a retraining cycle for ML models anyway - if not for feature/software release reasons then just for "freshness"

    Secondly a good model should need much if anything in the way of PII, most use cases are about acting on novel views of small-medium groups of people. Most use cases are not UK Rozzer "find the crims" types.

    Thirdly - for Black Box models you would have to prove that the PII has been retained in a format that still makes it PII - with is both unlikely and virtually impossible.

And you might get more precision with the neural nets because it could be more complex, but mostly that first one.

    Sounds a lot like academic studies

    This honestly sounds like the same problem as trying to have you data deleted from an academic study. By the time it is the published paper it is so detached from your identity and yet there are so many derived numbers and conclusions that they could not remove you without redoing the entire piece of research.

    So the balance of privacy and practicality here is all going to be around the correct process to anonymize the data on its way into the process. This is a pretty well understood process for academic papers I do not really think it should be that much of an intractable problem for AI researchers or developers.

    1. NetBlackOps

      Re: Sounds a lot like academic studies

      Sadly, we keep coming back to other researchers who have successfully deanonymized individuals from previously thought "safely" anonymized. That's even before we get into intersection of datasets.

  9. Mike007

    My understanding is that the algorithm doesn't contain the data, just a model that should output the correct answer when supplied with certain input and the data was merely used as part of the process of develping the model.

    I understand it to be similar to using one of those "equality questionnaire" things to produce statistics that say 70% of my customers are white males, then based on that I make a system that assumes a new customer has a 70% chance of being a white male... if one of my customers revokes permission regarding their questionaiire, am I obligated to go back and modify the report I produced to say that 69.9% of my customers are white males and modify the resulting system to say that there is a 69.9% chance of the new customer being a white male?

    Basically, is revoking a right to store the data the same thing as requiring you to modify conclusions that were based on summarising that data as part of a larger dataset?

    1. doublelayer Silver badge

      The problem being that a ML model may contain a lot more than a summary of the data. It might say that a new customer with no identifying information has a 70% chance of being a white male who would like to buy apples at a confidence rate of 62%, bread at a level of 73%, and lettuce at 52%. It might also say that a customer whose address is 1234 2nd St. is 99.5% likely to be a white female aged 42 who will want to purchase potatoes at 97% confidence, oranges at 88%, and bread at 99.83%. The problem with models is that you can keep asking them questions, and while they're not always correct, they'll take any information you give them and try to answer questions based on that info. In this scenario, address would not be a necessary thing, and a good developer wouldn't provide it. A bad developer might not notice, and an evil developer might provide it so you have a black box that's hard to audit but allows access to this data. This is why GDPR has to apply to all the source data they're about to use. If it's discovered that they violated privacy rules in obtaining the data to give to their model creation process, the models that resulted might contain parts of the data.

      1. Mike007

        Does it actually contain the fact that a 42 year old white female lives at 1234 2nd st, or just an algorithm that can produce a result that coincides exactly with reality for that specific example?

        I have bookmarked one of the pages that was generated by the library of babel algorithm. none of that text is stored on the server, it just generates data based on the selected variables... (a bookmark is shorter than telling you how to navigate to the location of that specific page of text, but the page was already there at that location before I went and searched for it)

        Yeah, that specific algorithm kind of demonstrates how complicated these things can get... is possession of the algorithm illegal in countries that ban certain forms of speech?

        1. doublelayer Silver badge

          It really depends how our notional algorithm was trained. The model stores information it thinks is useful, and the developer cannot tell it to retain information or block it from storing information that is provided to it. So if address was an included field, and the algorithm was trained in such a way that it came to the conclusion, correct or not, that address was a useful feature, it would probably store relationships of that nature. Somewhat crazily, in that case, it would think it could guess at every address, including ones it's never seen before (though a good system would lower the reported confidence rate). It's not guaranteed to contain that information, but it easily could.

          The major reason this could happen, outside my example of the evil programmer above, is where there are actually a bunch of patterns. Suppose that the 1200-1300 block on 2nd St. is primarily occupied by vegetarians (we're sticking with the grocers' model in this example). If the model was given this information, it could easily notice that people there are more likely to be ordering lots of vegetables and much less likely to order meat. This might convince it to keep more address information, because it was useful in that scenario. Now imagine that there is a large group of people, say a large extended family, who share the same surname and have specific recipes in common. Now the model sees a pattern where customer name is usefully connected to buying habits, and more of that data is retained. And now we have a model that stores two types of data that are next to useless, because they don't scale to the public at large, but would allow access to potentially private data. Removing that data would require retraining the model to exclude it. That's why we have to not put that data in in the first place.

            What you call “model” I call "profile".

            1. “Training” your data by dictionary definitions you create in each profile a huge number of truly significant patterns, which very accurately determine its semantic orientation. For this "training" must remove from the profile what I call "lexical noise", right at the stage of parsing (preliminary preparation) of the data. This deletion ensures that each profile can both be found and itself find only a narrow circle of other profiles.

            (I wrote in my patent: "Such lexical noise is typically superfluous predicative definitions that do not explain the central themes contained within the digital textual information and, accordingly, removal of such noise often results in an improvement in the quality of the structured data." In another I wrote: "If Compatibility=100% - most likely only absolutely identical paragraphs/passages can be found. If Compatibility=0% - all paragraphs/passages that have even one same word and/or predicative definition are found. )

            Then the presence or absence of some address matters only in combination with a variety of other patterns, since they will allow or not to overcome the compatibility threshold necessary for either receiving or transmitting information.

            Therefore in order for compatibility to really work is necessary to remove all lexical noise, which is impossible without a high-quality dictionary.

            2. If you train your date by "other data" and not by the high-quality dictionary then most likely you will not be able to remove its lexical noise. Indeed, this "other data" plays the role of a dictionary, defining parts of speech and the meaning of the words of your data. That is, you must be sure that the "other data" is able to adequately do it.

            And now please explain me why spend time and a huge number of resources on the creation a new dictionary when there is the old and proven high-quality? Only because you don't want to pay me?

            3. There is a sentence "Alice and Greg swim with joy." If a system doesn't see each word's part of speech, then the word "joy" can be taken as a noun (name) "Joy", resulting in erroneous patterns when parsing the sentence.

            For instance, if the word "joy" is a noun-name, then these patterns appear:

            - Alice swims

            - Greg's swims

            - joy swims.

            If the word "joy" - an adjective, then these:

            - Alice swims with joy

            - Greg swims with joy.

            You what may or may not happen, some system see the words 'joy" and "Joy" the same - try to type 'ilya geller" and "Ilya Geller" in Google?

        Now do you understand why I couldn't get any support from the Government? Why have I struggled for 10 years? I suggested AI to be owned by us, not by third parties like the CIA (Google and FB). But the state, in the face of its Almighty agencies, is not interested in our privacy and I did not get any funding.

        Fortunately, we live in the country of bestial capitalism and someone will surely start selling AI with a privacy option, given our desire to have our lives protected from invasion and pay for this. That's what I hope to.

    ...that the operation to remove the data be termed a "loborkomy".

      On the note of AIs, you know how feeding an AI good literature to train one to write prose gives bad results?

      I wonder what would happen if we gave them your posts.

    Well... for deletion of human memories, progress has been made:

    https://www.telegraph.co.uk/science/2016/03/12/scientists-have-discovered-how-to-delete-unwanted-memories/

    That might point to ways. Next up: Can skills and ability to recognise things be selectively deleted?

      seems to work

      I mean, *I* can still recognise traits no one sane would want in a world leader, but something's happened to the rest of the world. It must be something in the environment / radishes* / celery*. I mean, 'no, we don't want nuclear power because that won't ruin the atmosphere and my friend's friend who secretly advises the gas industry says its scary' , 'lets' vote for Boris / Trump / etc because I wouldn't trust them with anything more dangerous than a sinclair c5'

      Alert

      Pretty sure we've been able to delete human memories for decades

      ...either by the application of voltages across the temples (ECT), or, more drastically, through leukotomy / lobotomy. It;s just that you don't necessarily get to decide which memories get deleted, or how well.

    Even more important than the ability to delete data is an algorithmic audit trail. It should be possible to have a complete log of the full decision tree in order to ascertain that decisions affecting people in the real world have been arrived at reasonably. In fact there should be a standard to which all 'AI' systems must be held.

    1. Charlie van Becelaere

      Good luck with that. I agree there ought to be such an audit trail to any AI training, but I don't think the folks involved really know enough about what's going on inside their processes to manage anything remotely useful.

      Black boxes seem to be equally opaque to all concerned.

    Another great reason

    This is yet another great reason to do everything possible to avoid having our data collected in the first place.

  16. I.Geller Bronze badge

    What a stupid idea! To train date on another date! Why not instead to train it on dictionary? Does training date on another date mean creating of a new dictionary? So why waste energy, money and time creating a new dictionary when there is already a well-established old one?

    How do you unlearn P0rn?

    Is it even possible?

    saving millions

    Dictionary is a book or electronic resource that lists the words of a language (typically in alphabetical order) and gives their meaning, or gives the equivalent words in a different language, often also providing information about pronunciation, origin, and usage.

    Training your date on dictionary you get a ready-made index, plus you get a huge number of patterns that explain the meaning of the used by you words. Instead of many gigabytes of texts you can use only 20-26 megabytes, saving millions.

    The AI database is a blockchain database, that is

    - long-ago use of information

    - and the presence of rarely used templates

    can result into automatic deletion of information.
