  1. Re:Why not digital destruction? on Ask Slashdot: Data Remanence Solutions? · · Score: 1

    Maybe I misunderstood what the article author was suggesting. It sounds to me from the writeup that they already have unencrypted drives, and he is proposing that they encrypt the drives then destroy the key as their disk destruction technique. If that's the case then taking time to encrypt the drive would both be much slower than a random pass, and not as secure: if not done correctly it could leave unencrypted data behind in unused blocks, and there's always a (fairly negligible) risk that the encryption algorithm gets fundamentally broken.

    Meanwhile both methods have the same remenance problems, but a random pass could be done multiple times (though I guess they could encrypt the encrypted data with a new key).

  2. Re:Why not digital destruction? on Ask Slashdot: Data Remanence Solutions? · · Score: 1

    Yep, this is better than encrypting the drive in that it's possible to secret away a copy of the encryption key and later unlock all the data, or perhaps the algorithm used for encryption gets broken, so suddenly the data is readable again, and so forth.

    Encryption offers no advantage over a strict drive wipe, particularly with random data. Realistically multiple passes are not needed because modern bit densities make it improbable that magnetic memory can be meaningfully recovered. Thinking it does demonstrates failed thinking. If you're encrypting just certain files, then empty sectors may still contain unencrypted data. If you're encrypting the whole drive with the intention that it's unrecoverable, then random passes are the same thing.

    However, I see any soft destruction as most likely being completely out of the question. It's impossible to look at the outside of a drive and know if it's been correctly wiped, no matter how good the wipe process was. To audit the destruction you'd have to load up each disk and examine it electronically one at a time. And if full-disk encryption was used (maliciously), but it was advertised as a random wipe, that would be impossible to spot.

    If it's not your own data that you're destroying, physical destruction of the device is the only way to be sure it was done as advertised.

    There's an app for Android phones, called Antennas. It shows you the location and status of nearby towers, and can be configured to run and collect the status of nearby towers in the background.

    If a modified version of this app was used to crowd-source information about towers, false towers such as this could be identified. These mobile false towers will be physically located close to the interception victim, and will be a lot less powerful and have a lot less range than a typical tower. They'll also have less capacity than a normal tower, and maybe be physically located in an unusual spot (eg, on the street). These details should be able to be aggregated and the information used to warn about a new tower or a tower which has moved, or a tower whose signal strength is not on par with typical towers. Anyone curious about the status of a suspicious tower can drive out to its location and have a look to see if there's a real tower there, or instead it's a "news van" at that spot.

    It seems like on a rooted phone, you ought to be able to blacklist certain towers, maybe give the device a whitelist of verified towers to use in a certain area. Maybe even make that black/whitelisting selective - only disable suspicious towers when making / receiving a call (since it seems likely the purpose is not location awareness, but call interception).

    With so much of that capital on Wall Street today being typically invested only for minutes, if not seconds, I don't think it offers much value to the company.

    There's a huge problem in the US economy at large where stock holders don't care about what's good for a company's long term prospects any longer, they care instead only about the shortest possible term changes to stock price. They incent CEOs to make decisions which raise stock price for today, but which cannibalize value from the company in the longer term. The CEO's have these golden parachutes, when things start going bad, they bail and take a pile of cash with them, so there's no downside.

    Except that a company which employs people and which produces a product which is presumably valuable to society is less able to employ and less able to produce.

    I think a new tax is in order. Tax stock profits based on how long the stock was held for. Anything 5 years or longer gets zero capital gains tax. Anything shorter gets taxed on a scale according to how long it was held, with the highest tax reserved for any stock held for less than 24 hours. The tax rates should be sufficiently steep that most investors are looking to invest for at least 1 year in order to maximize value.

    High frequency trading contributes nothing to society, it merely saps value out of the economy and puts it in the pockets of those who can afford the hookups. Worse yet it causes some of our best and brightest intellectual minds to waste their skills trying to game a system rather than produce something of value to society.

    The loophole I mentioned is that although they must "produce" it themselves, it's not difficult to create a financially independent subsidiary which is effectively managed by some third party, in space rented from that third party and on equipment owned by that third party for a negligible amount, which then sells exclusively to that third party for prices reflecting what would have been the original licensing fees.

    Let's say New Patent Troll Incorporated (NPT, Inc.) "invented" a widget (in the past tense, along with some entirely-internal paperwork supporting this), which Some Startup Company (SSC) has a patent on and recently demonstrated a market for. Bob's Widget Supply (BWS) contacts SSC and asks what it costs to license the patent so they can produce it too. SSC isn't really interested in price competition since they have been working without income for the last few years, and have a lot of debt to make up, so they demand $0.50 per unit in royalties (SSC selling the widget at $1.00 wholesale).

    BWS doesn't like this price, they realize that they can't compete against SSC like that (whose net is around $0.30 per unit). So BWS contacts NPT Inc. NPT, Inc., after a few days of "exhaustive" searching is able to produce some documentation showing that they have been using some prototypes of the exact same invention. NPT, Inc. offers to sell this product to BWS for $0.10 each, but as part of the agreement, BWS must provide manufacturing space and equipment to NPT to "bolster" NPT's current supply line, and must cover the increased costs of payroll and materials acquisition for NPT.

    Basically NPT becomes a proxy for BWS to manufacture this item, and they pay a greatly reduced "markup" on the final product, but BWS is responsible for all of the details. On paper, NPT is manufacturing this product and selling it on the market exclusively to BWS at a rate which allows BWS to directly compete against the patent holder, because the law says NPT is allowed to do this even though they don't hold a patent for the product and SSC does.

    The physical widget example is a little strained, but NPT can charge any amount less than SSC's license requirements, and it's a better deal for BWS. But in the technology world, when it comes to things like software patents, there isn't actually manufacturing involved. So there's no shady setups to create where BWS has to provide manufacturing capacity to NPT, NPT's actual costs for "producing" more units of a particular software product are trivial, and that's the arena where this really creates a truck sized hole in the patent process.

    Maybe SSC could sue NPT. If NPT is a shell corporation created by BWS explicitly for this purpose, they draw things out to ramp up legal costs for SSC, then bankrupt NPT. SSC, being a startup (and therefore the "little guy"), will have had to have exhausted a lot of resources to shut NPT down, and in the mean time, BWS has spent a few years with free reign on the market, and with no permanent consequences in the end. But more likely SSC realizes it's a legal quagmire and sends a few threatening letters for good measure, but never really pursues it since they see they would bankrupt themselves and accomplish nothing.

    Sure, they don't own a patent that they can sell, and they can't sue others for breaching the patent (so it's not an item in their patent warchest), but they can compete directly with the actual inventor without needing to pay royalties, including selling a competing product on the market.

    There's a loophole here big enough to drive a truck through. Even though they can't license this invention directly, they can still accomplish the same thing in effect. The third party is their "distributor" and pays them a "commercial" rate equivalent to whatever the original patent licensing fee would have been. This company just has to be responsible for the manufacturing (heavily and directly subsidized, perhaps even overseen by the third party).

    Because they have the resources to cast the widest possible net without regard to working out specifics or surmounting challenges present in the invention. Basically they are "inventing" in the sense that they think of an idea, and document it entirely internally (read: completely forgeably), then let the market prove the invention worthwhile. They can then pursue only those inventions the market has demonstrated a demand for.

    In effect they can let third parties take all the risk while they reap the reward. Small inventors don't have the resources to do something similar, so any time they patent something, as soon as they start seeking royalties they potentially risk having invested years of research and work creating something incredible only to have a big corporation show up claiming "Oh, we've been doing that all along, it's just that nobody but these two guys in our extremely highly paid R&D team knew about it," and start selling licenses of their own. Their investment is much lower, and their risk is practically none.

    I could understand if this exception permitted continued use in the same manner as the company has already been using it. That is, if any scale, so you get the ability to sell it the same as the patent owner does," is just a smack in the face to anyone without enormous R&D budgets.

    Since the patent system is intended to reward people for taking the risk of inventing, a clause such as this which shifts the burden of risk from the big kids to the little kids is directly opposed to the design of the patent system in the first place. It's turned into a cash-back guarantee for big companies, and this legislation furthers that trend.

    He does explain why:

    As one example, the Act expands the Prior Use defense to patent infringement to apply to all inventions (it was previously limited to business method patent claims) in a manner that encourages those with sufficient R & D resources -- generally, large companies -- to discover, document, use in an "internal commercial use," and maintain as a trade secret new methods and/or materials producing a "useful end result" which can then be sold or transferred with impunity. If a patent application claiming the new methods and/or materials is filed a more than a year later by another entity, and issues as a patent, this prior internal commercialization, or the transfer or sale of the end result, is immune from patent infringement, and is protected thereafter so long as it is continuously performed.

    Basically if they do a large amount of internal R&D (most big tech companies), anything they piloted internally gets them a license to the tech. Even if you come up with an amazing new idea, if their R&D team spent any time on something similar, they can sell it commercially even though you have a patent.
