EFF Warns TI Not To Harass Calculator Hobbyists

Ponca City, We love you writes "The EFF has warned Texas Instruments not to pursue legal threats against calculator hobbyists who perform modifications to the company's programmable graphing calculators. TI's calculators perform a 'signature check' that allows only approved operating systems to be loaded, but researchers have reverse-engineered signing keys, allowing tinkerers to install custom operating systems and unlock new functionality in the calculators' hardware. In response, TI has unleashed a torrent of demand letters claiming that the anti-circumvention provisions of the Digital Millennium Copyright Act require the hobbyists to take down commentary about and links to the keys. 'This is not about copyright infringement. This is about running your own software on your own device — a calculator you legally bought,' says EFF Civil Liberties Director Jennifer Granick. 'Yet TI still issued empty legal threats in an attempt to shut down discussion of this legitimate tinkering. Hobbyists are taking their own tools and making them better, in the best tradition of American innovation.'"

      They're not. But facts wouldn't get in the way of some good old fashioned hyperbole, particularly if it involves whatever vendor you're choosing to hate.

      Wrong, the crap that Apple pulls is way worse than TI can dream of.

      Calculators are not advertised or thought of by most people as mobile computers. TI doesn't advertize "There's an App for that". It's sad that Apple forces developers to jump through hoops just to get an App proved and bans any political or other useful Apps under the name of duplicate functionality. Apple also has a forced developer tax of 30% and hence prohibits downloads from the developer's website. The alternative is to jailbreak, but it breaks when updated and is not for casual users. Apple even says that the iPhone and iPod touch can be considered as netbooks(which are otherwise normal computers without the App store bullshit).

      Also it is a lot harder make claims about DRM and piracy and such when you are dealing with a calculator. So this legal fight would be easier to win than eg vs Nintendo who can say "if we don't do it we will lose X amount of money." TI can't exactly claim that they are losing money from this because they don't sell any kind of software add ons for their calculator (afaik.)

    The product was not sold as a computer or development platform. It was sold as an end user product with documented functionality as described in the user's manual. Sure enough, when the hacks disable their machines TI will get the support call. Most slashdotters will probably flame me for this.

    I would be very surprised if a calculator hobbyist tried to get support for a modded device. And it is pretty easy for TI to say the warranty is void so STFU in that situation.

    It's really hard for me to see how TI has a case under the DMCA at all. They're claiming the anti-circumvention clause, but it doesn't seem to apply here.

    The anti-circumvention clause makes it a violation to circumvent copy protection -- but what the hobbyists are circumventing in not copy protection, it's a validation key. Without the key, you can still read and copy the existing OS without a hitch. The key is needed to put you own intellectual property on the device, no to copy theirs.

    The key itself was never published by TI, and as far as I can tell was never registered with the copyright office, so copyright doesn't apply to that (even if it can apply to a number, which I doubt.)

    So where's the copyright violation? this looks like a criminal (bad faith) abuse of the DMCA to me.

  5. Re:Perfectly valid by QuoteMstr · · Score: 4, Insightful

    No. The DMCA reads "No person shall circumvent a technological measure that effectively controls access to a work protected under this title".

    How does TI's signing system do that? The TI system just prevents people from loading a new OS onto devices that they already own. It doesn't protect access to work.

    The DMCA is a bad law, but it's not so broad as to say "everything to which a technology company with a market capitalization of over $10 million objects is henceforth illegal."

Will T.I. really lose oodles of greenbacks because Joe geek likes to mod his calculator to play Mario or run Linux or watch porn (last item questionable). I highly doubt people hacking their calculators will cut into revenue, if anything it will increase it by bolstering interest in the extended possibilities of their products.

    All sorts of companies produce the exact same hardware and then have a registry bit/flag hidden somewhere to enable the more expensive features. nVidia and their Quadro cards comes to mind... Or Intel and their underclock/overclock crap... the chips are identical, one is stamped with a different number and frozen at a different multiplier.

    That's why those types of things are done with fuses, so that's it's virtually impossible to re-enable features that have been fused out. It's certainly impossible to do purely in software.

  9. How do you copyright factors of a number? by Myria · · Score: 4, Insightful

    The numbers they are distributing are the prime factors of the RSA key used by the calculators. The factors were determined by a general number field sieve calculation; this was effective because the keys are only 512 bits long.

    The public key itself - the modulus - might be subject to copyright. However, the prime factors were never copied from TI - they were mathematically determined from the modulus. Attacking them because they distribute numbers mathematically derived from a copyrighted number is new legal territory.

    If numbers derived from a calculation on a copyrightable number are themselves "derivative works" in the copyright sense, it would cause far-reaching problems well beyond calculators. For one thing, it would be illegal to distribute SHA-1 hashes of copyrighted material without permission.

    Well, stick around some more, because it's not what the DMCA is designed to prevent.

    As others have pointed out, you can only invoke the anti-circumvention provisions of the DMCA if the technological protection measures are controlling access to a copyrighted work. Simply bypassing a measure alone is not a violation of the DMCA.

    In this case, they obtained keys that allow them to install custom software on the device. Where that software comes from may be a copyright issue, but that is not relevant to the overall matter of whether obtaining and using the keys is a violation of the DMCA. These keys control whether the hardware accepts given software; rather than controlling access to copyrighted software, the keys, in a manner of speaking, control the software's access to the hardware, so it's not a matter for the DMCA.

    Because in the case of direct tv, you're paying for the service, not the hardware. If i go down to Best Buy and shell out $200 or whatever for a new TI-89 Titanium (my classic TI-89 is starting to look somewhat stayed...), then I never need anything from TI again. I take that thing, and I'm done. No real need to plug it into anything; TI doesn't beam the CAS down via CDMA wireless signal like some sort of Kindle thing.

    Basically, with the calculator, the hardware itself is the FINAL PURCHASE, whereas with DirectTV, you're basically renting the hardware as a means to access a service, which is what you're actually paying for in the end. Cheating on what you're paying for as far as channels go is clearly wrong. Modifying a piece of hardware that once bought never needs to have any interaction with the mother company again is completely different.

  12. What about the need for uniformity? by matzahboy · · Score: 5, Insightful

    Although a Ti-83 can definitely be enhanced by a custom OS, the usefulness of a Ti-83 would greatly decrease for students if custom OS's existed. On many standardized tests, including the SATs and ACTs, the tests specify which calculators are permitted for the test. They have a very specific list, based on which ones they think are not too powerful and would give an unfair advantage to a test taker. All ti-83's are allowed on either test for example. But if the makers of the test knew that people could have ti-83's that had undocumented, unfair functions (such as symbolic algebraic solving as in the ti-89), the test makers would most likely disallow these calculators. Why do you think TI still sells the Ti-83 plus, a calculator created in 1999? Certainly hardware abilities and processor speeds have greatly increased in the last 10 years. The reason is that test makers will not accept calculators with very powerful abilities. They want the student to solve the problem and not the calculator. When browsing calculators at education.ti.com, each calculator has a page called "exam acceptance" (ex. http://education.ti.com/educationportal/sites/US/productDetail/us_ti83p.html?bid=2). That is because TI sells a large number of its calculators to students. The custom OS's could greatly hurt TI's reputation in the eyes of its biggest supporters: the test makers.

      Well cry me a river, why is that the problem of hardware hackers who have already PAID for their devices? If we had a law against every activity which might damage somebody else's business model then we would be living in a police state already. If the test makers don't want "powerful calculators" used on their exams then why not simply ban all calculators? If they are interested in testing mathematical knowledge rather than rote arithmetic or button pressing ability then why not simply design the test along those lines in the first place and enforce the suggested ban against electronic assistance? Technology is a moving target which will change over time; attempting to fix it in place by law, for whatever reason, is both destructive and counter-productive.

      Only one problem with that. You ever seen how people abuse things that they are borrowing even for a short time? Plus the calculators would have to be lugged from test site to test site giving even more room for them to be broken.

      Calculators are cheap. Just buy more.

      And what happens to the person who can't get a calculator because one got broken on the trip to the test site?

      Bring extras or refund the test taker's money. It's not hard.

      Truly, the test makers should just go back to not allowing programmable graphing calculators and allow nothing better than a scientific calculator. That is all a student should need for taking a test.

      And how do they know that a student hasn't modded their calculator to be either "programmable" or a communication device? This whole affair illustrates a flaw with the standardized tests. Namely, that they're more interested in reducing liability (and a rather weak liability at that) than in producing a reliable and trustworthy test.
