      Thank heavens you aren't allocating bit-space then. Part of the power of what you think are excessively large address spaces comes from the fact that they stay sparsely populated (and the resultant ease with which you can perform classifications due to that sparseness).

      Example: IIRC there are less than 256 countries in the world. One possible IPv6 allocation is an 8-bit country code field embedded in the 128-bit address, leaving 120 bits for each country to address devices. And then in the US, for instance: 6 bits for the state field, 8 bits for the county field, 8 bits for the city field, still leaving 98 bits for addressing *per city*. A similar example holds for 96-bit barcodes.

      I could give you uniqueness using only 64-bits.

      Sure, for a while. Back in the 70's, I'm sure they figured that 12-bit barcodes were plenty. According to the article, they're now starting to run out.

      It's called thinking ahead: Design a system that will last at least twice as long as you think you'll need. Yeah, 64 bits is incredibly huge. They're talking about serializing every product made by every company with a unique id. So say we plan on it lasting 100 years. That's still like 184,400,000,000,000,000 unique id numbers, per year (64bit). Actually, that does seem pretty damn excessive.

      But who knows - maybe there will be other uses for this space as well. Using a few bits to encode sizing/weight information, color, hazards, if it's flamable, disposal instructions, etc, to allow simpler devices to read it without having to link to a database somewhere. A good example of this is the licence scanners some bars use: they swipe your drivers licence, and it shows the info encoded on the card, and they compare it against the info printed on the card. It doesn't link back to a database to verify anything, its just a simple device to help prevent fake id's. Same sort of thing could apply here for shipping purposes, and probably lots of other things, too.

      It's a lot easier to just use 96 bits now, than switching to 64 now, and then having to switch to 96 again in a few (or many) years.

        The article is pretty confusing. This is not a barcode at all: it is just setting up the number space that will be used for RFID tags. All that has been decided, AFAICS, is that it will be a 96 bit code in the RFID chip, MIT will hold the central registgry, and many interested manufacturers are meeting to agree on how to divide up and administer that 96 bit space.

        Bit of a "Duh" if you ask me. Of course it has to be done, but this is pure implementation territory: it doiesn't affect the privacy issues on bit.

        Mind you, I do wonder what the delta cost on the RFID chip of moving from 96 bit to (say) 128 bit - or even 256-bit. While I agree that these things are going to be produced in trillions and therefore millionths of a cent add up, I would have thought that most of the cost was constant per unit - slicing, packaging, testing etc.

It also said this new system would take around a decade to catch-on, because obviously the cost of printing a bar code on an already existing bit of paper on the product is a lot less than creating a little microchip/transmitter/thingy.

        The VIN is truly unique; no two cars have the same number. They are unique amongst a common manufacturer, and unique amongst all automotive manufacturers. Every car, truck, minivan, SUV, etc. has one of these numbers, often written in multiple places, and oftentimes PHYSICALLY STAMPED in the material of the car so as to prevent fraud (it's illegal to remove this privacy-infringing device!)

        These numbers are not protected at all; they're prominently displayed on the dash of all vehicles equipped with them, so that anyone simply walking past your car can look in and record the number. From it, they'll know what manufacturer produced your car, the car's series, its body style, engine type, emissions, what model year it is, what factory it was produced in, and on top of that, A SIX-DIGIT UNIQUE IDENTIFIER!

        This problem has existed for decades, and few people actually know the evils that lurk inside! This must be stopped! Stand up to your car manufacturers, tell them you WILL NOT BUY another vehicle from them until this travesty is corrected!

Network configuration would be simplified - just scan the barcode - and the item wouldn't need a UPC *and* a IPv6. They would be the same. That would simplify marketing and tracking as well, items such as coke cans and underwar could simply be ping:ed on the net. No need to bother with those RFID tags.

    UPC-A barcodes are 12 digit long. There are many many other types of barcodes, including 2D barcodes that can hold up to 1K of data on them. They just have to pick another type of barcode, like CODE128, for consumer products and declare it the new standard. No need for revolutionary changes here.

    Article states:
    "No more inventory counts. No more lost or misdirected shipments. No more guessing how much material is in the supply chain--or how much product is on the store shelves."
    Boy, these guys need to get into the real world. Stuff gets spoiled, damaged/dropped/spilled, eaten by rats, misfiled/misplaced, etc. Sure, you query the rdif tags, and they report back that you've got 6 cans of #2345 white paint in stock. Now you go to ship all 6, and find that 3 cans are leaking, 2 of the other cans are mislabeled, and the last one, someone's opened and "borrowed" the contents to repaint the john..

    You'll always have a need to do a physical audit.

  • I'd rather have each item identified by a unique bar code than a unique RFID chip. Bar codes don't broadcast information. Unfortunately I predict the more invasive technology (RFID) will become the industry/worldwide standard.

    Man, I don't want to be respomsible for that database.
    Hey, Microsoft, maybe you'd like a shot at this one? Then everyone would be happy knowing that there data may not be secure, but when it crashes (not if), we all get to start over.
  • I know everyone is going to be jumping on the "1984-esque abuse of privacy" bandwagon shortly, but I have to say (donning flame-retardant suit), that this doesn't seem like a bad idea.

    I know there is the potential for this to be misused, but to be honest, I don't think the potential is much worse. If a big bad tracking company is going to follow me, I don't feel any worse about them knowing that I bought this specific can of Coke rather than just a can of Coke.

    While reading another article about those nasty RIFD tags the other day, I suddenly had a thought....

    Why not just attach the RFID tags to the product packaging rather than permanently to the product itself. The packaging gets thrown away, not the product. Most of the privacy issues simply disappear. (Other than that someone could run your trash through an RFID scanner, but would still need access to a database in order to determine that that number is a particular subversive book that you should not be reading.)

    I'm not saying it's a total solution to the problem of RFID tag privacy. But if tags were affixed to packaging rather than products, most / many privacy issued just go away. (Some remain.) Or have I overlooked something major?

    So you have a 96-bit ID number. That means you have 2^96 unique numbers.

    Make a tag for each one.

    Let's say for the sake of argument that the tags weigh 0.01 grams.

    Now make all 2^96 of them. You have just created 792,281,625,142,643,375,935,439.50336 kg of tags.

    That's a shitload of tags! For reference, Planet Earth has a mass of 5.972e24kg. Your tags would weigh 1/132 as much as the entire planet.

    That's less than 1%, but that's still a MAJOR volume of tags. We'd be choking on them. They'd be everywhere.

    At 1,000,000 tags per second, how long would it take to manufacture 2^96 tags? 7,922,162,514,264,337,593,543 seconds. That's 2,512,308,552,583,217 years.

    When I read this line (from the article):

    "Under EPC, every can of Coke would have a one-of-a-kind identifier."

    It occured to me that it's quite possible that such unique id's on consumable items could later get tracked back to their purchasers, then automatically impose a littering fine on them if said Coke can is found empty and discarded on the ground somewhere.

    I don't really see that as becoming a reality, but it's possible.

    • On the upside, tracing individual packages of products means more precise recalls. Also, companies will be able to track all the steps a product went through, from manufacturing, to storage, to delivery, to shelf life, to consumer. Yes, it has got its privacy issues but the benefits exist as well.

      The same exact thought occured to me. Right now, if someone dumps garbage in, say, a park the only way they can investigate it is if there is a witness or they find addressed mail (or similar papers) in the pile. Now they'll just have to put bar codes on all of those damn Dunkin Doughnut coffee cups I constantly see on the ground.

      I'm sure we'll see a market for microchip destroying devices of some sort for home use if RFID's ever take off in significant numbers.
    • if said Coke can is found empty and discarded on the ground somewhere.

      All it would take is a little wind to blow it out of the over-full trashcan it was carefully placed in, or a homeless man to accidentally drop the can on the way to the recycling center.
  • Well 96 bits is a little inconvenient for storing these values in a database.

    2^96 is not nearly enough for every molecule on earth. Avogadro's number is 6 * 10^23, which is approximately the number of protons that weigh 1 kilogram together. Most molecules weigh less than 100 protons. 2^96 = 8 * 10^28. So at most 10^7 kilogram can be tagged uniquely with ECP. The earth weighs approximately 6 * 10^24 kilograms. Yeah, those "MIT boys" are really smart...

    When our whole lives are encoded in a database, what is to stop future legislation that punishes people for crimes they never knew they commited? What about people who make mistakes in their young adult years and want to reinvent themselves somewhere else but can't due to their digital legacy? What about people whose business isn't our own but who have access to this data and use it against us?

    Databases of this scale are immensely dangerous regardless of what trivial conveniences they allow. These databases can take our lives out of their social context and make us vulnerable to blackmail and extortion by public officials.

    These databases also violate the Fourth Amendment. What about a future where law enforcement officials don't even need to step on a person's property to execute a search?

    Simply, privacy is fundamentally important and is a fundamental human right. Only when citizens can control their own information, can a proper balance of power be mainained in a representative democracy like the USA. Remember, those who hold the information are those who are truly in power.
    • Reality is that the likelihood of extortion and blackmail over previous events in life becomes far less likely if everyone is held accountable. Currently the system is built more around how much money one can throw to make things go away.

      The sad state of affairs, particularly in the US, is that everyone is expected to live up to a high level of morality, because everyone hides what they've done wrong. When no one can hide what they've done wrong, the system as a whole becomes far less black and white.

    After reading the article I don't understand a few things:

    1. Why the article's title on CNET mentions "futuristic barcode" when the project is apparently in relation to low capacity (96bit) RFIDs or the like.

    2. Why it took 5 years to develop. RFID technology is readily understood. Databases are readily understood, wireless communication is readily understood. Prototyping hardware and writing some connectivity software should not have taken 5 years for such a "group". I'm either dissapointed or confused.

    3. Why give each tag a only specific serial number that MUST be looked up in the database to ID it. The current barcode mass-grouping is still valid even with more bits. A stripped down database could then be used for off-line reading and you would still know the manufacturer and possibly the product family. For example barcodes starting with "636920" are from O'Reilly; all barcodes starting with "05000" are from Nestle. Isn't that much easier than having NO idea what "aj380dk358fh3k8i" is?

    4. Why access a database directly? Why not use the Internet and stanard DNS and HTML/XML? Purchase a domain and make simple IRLs that include the tag info: ? The server would see the code, and send back a response containing one of two things: 1: the product information in XML (including a link to more info from the manufacturer), 2: an error. Such a thin HTTP/HTML client could be written quite quickly and be embedded in almost anything. There are already many synconization and caching sytems in place for HTML.
