Researchers Find 'Mind-Control' Gaming Headsets Can Leak Users' Secrets 107

Sparrowvsrevolution writes "At the Usenix security conference in Seattle last week, a group of researchers from the University of California at Berkeley, Oxford University and the University of Geneva presented a study that hints at the darker side of a future where we control computers with our minds rather than a mouse. In a study of 28 subjects wearing brain-machine interface headsets built by companies like Neurosky and Emotiv and marketed to consumers for gaming and attention exercises, the researchers found they were able to extract hints directly from the electrical signals of the test subjects' brains that partially revealed private information like the location of their homes, faces they recognized and even sequences of numbers they recognized. For the moment, the experimental theft of users' private information from brain signals is more science fiction than a real security vulnerability, since it requires tricking the victim into thinking about the target information at a certain time, and still doesn't work reliably. (Though much better than random chance.) But as BMI gets more sophisticated and mainstream, the researchers say their study should serve as a warning about privacy issues around the technology of such interfaces."

        Technology-enabled telepathy is actually what I call cellphones today : you hold a talisman, another talisman rings and transmits speech. Just implant it if you want, but the magic is already done.
        • Not entirely telepathy, IMO. It still requires actual speech. It's functionally equivalent to telepathy in that another person knows what you intended to convey, but the requirement of actual physical speech brings it back over the line.

          Cellphones transmit sound, and speech is just a subcategory of that.

          When I said "telepathy", I meant what a person is *thinking*. This could include spoken words, but it could also include what is being seen, or even imagined or remembered.

          You misunderstand the meaning of the word. Telepathy is transference of thought or experience. It isn't simply the transfer of voice, words, or even expression of ideas. The roots would be "tele" and "pathe", which would translate as "distant" and "experience" respectively. For your cell phone, I think "distant voice" would be far more accurate, or "telephone"...

          Though, smart phones with cameras might also fall under "distant sight", or... "television".

          • Yes, but we are speaking English, not Latin. In English, Telepathy refers specifically to the direct transference of thought messages from one mind to another mind, without first traveling through intermediate mediums such as text or speech, perhaps even disregarding the need of language. To suggest that using a cellphone is a form of telepathy, is much the same as suggesting that shouting to a person across a large room from you is a form of telepathy. While this is apparently true for the definition of "t

      We've been taught that the only people who need privacy are terrorists or pedophiles.

      So, why would anyone need to go through the trouble of reading our minds when we've been pretty well conditioned to just hand out our personal identifiers without thought?

        I'm not certain why this is modded funny instead of insightful. We have been programmed by popular media and life in general to devalue privacy.

        Actually, you've been programmed by the media into believing privacy is something historically "normal". As a general rule in human history, privacy has been totally foreign. People always knew what their tribe, hamlet, neighborhood or building were up to. There wasn't an expectation of any sort of privacy, for anything from actions, to sexual activities, to hygeine. It just simply didn't happen.

        Privacy, as a popular expectation, has a lot more to do with manipulating people. Shame is a powerful method of control. When society convinces you that you should be embarassed about something, the person who knows it gains a lot of power over you. If everyone knew it, there's no power. Shame, and the associated need for a concept of privacy, were constructs that arise over and over as ways of controlling a population.

        • You're basically right: as I understand it, in America around either pre-Colonial or Colonial times, you were expected to keep your windows open (or at least unshuttered and with curtains open) so that neighbors could peek in and make sure you weren't up to anything ungodly. Failure to do so would have been regarded as suspicious.

          But there was still shame in those days, despite the expected lack of privacy. You could easily be shamed for what you did right out in the open. The concepts of shame and priva

Soundproofing is kind of a prerequisite for home privacy. If people can hear you doing something they might just as well see you doing it, especially if one of the many town gossips hear you. It also helps if most homes had multiple bedrooms, much less multiple rooms, which from what I read most colonial homes did not. Actually

      This is another one of those cases where the authors want to write about a science fiction scenario that doesn't exist like direct neural input so they do an EEG study that in no way resembles the scenario they are imagining. EEG is terrible for extracting information so there's not much to worry about.

      • Alot depends on the required statistical accuracy of the information you are trying to extract, and the costs associated with a false-positive or false negative.

        If you are trying to prove guilt/innocence in a court of law or planning to bomb some remote village based on "intelligence" then its a pretty poor method, as with torture.

        But if all you are after is a better than average statistical correlation, then might catch the attention of advert-targeters and fraudsters. From inside an EEG controlled MMOG, y

      • EEGs are terrible when used as polygraph in a court of law. This is because they are not perfect and make mistakes fairly often, therefore cannot be used as evidence beyond reasonable doubt. However, if you want to get "some" information about a person, with only a degree of certainty, they are pretty damn good.

      Not watched the Mythbusters episode about the lie detector? Apart from the absolute rubbish asserting that polygraphs work (despite there being NO scientific evidence that they have ever or could ever work and vast evidence to the contrary - and HUGE problems with their experiment setup in the first place), they do a bit where they stick people in MRI's, EEG's, fMRI's, etc.

      Basically, it's hard to tell without a very good MRI scan happening *as* the person lies, real consequences if they are found out, complete amateurs being tested, no counter-measures being taken by them, huge amounts of analysis, etc. to say if someone is lying. But if someone doesn't want it to be known they are lying, it's almost impossible to tell from any external measurement.

      And if you can't do it with medical-grade EEG or room-sized MRI results, you can't do it with a gaming headset for the next 30 years.

      Hell, the US is just about the only "first-world" country that's EVER allowed polygraph results to be used as "evidence" in a court of law.

      It's just that shite, and unreliable, a method to detect what someone is thinking. And if you can lie automatically and convincingly, then you have nothing *TO* detect in the brain. At least until you can *literally* read people's thoughts as if they were sentences being spoken aloud about what they intend to do.

      Hell, our knowledge of the brain at the moment stems mainly from waiting for someone to have a bolt fired through their brain by accident and seeing what facility they lose and what parts of the brain were damaged. Above and beyond that, the brain's a black box of which we can only measure "activity" by way of measure electromagnetic changes. That's like trying to tell what colour object is inside a opaque box that you can't touch by waving a metal detector near it.

      • And if you can't do it with medical-grade EEG or room-sized MRI results, you can't do it with a gaming headset for the next 30 years.

        That is why the "it" is likely to be targeted advertising not the extraction of evidence for use in court. Marketing doesn't need the level of accuracy that a court would.

    • by jovius ( 974690 )

      The problem is that you'd first have to record a huge amount of EEG data correlated with the verbal output and the perceptions of the person to be questioned, to construct any sort of model to be used later in the interrogation room. Otherwise the EEG data is mostly meaningless noise. Besides the person with the EEG headset can obfuscate the interrogation ad infinitum by pressing teeth together for example (thus enhancing alpha waves), or moving the facial muscles in some other ways.
