Should be relatively trivial to break the encryption, since it can't be over 40-bit (or 56-bit if the company joined the kiss-ass alliance). Probably just as easy or easier to disassemble the software or do some creative tweaking of Windows DLLs to intercept data. Custom hardware is probably out due to cost and distribution problems, and even with it, it's still possible to intercept data between the hardware and the software, or the software and the OS. -- Brian Buchanan brian@smarter.than.nu No security through obscurity!

Note that, if the person who has the authority to modify the code of the operating system wants to intercept the data, even a "real" OS can be easily modified.

Ahem. Notice the dateline on the article. Calgary. Not a problem, eh? Plenty of Canadian content in that one, so they could even show it on TV if they wanted to.

On the other hand, if they can inhibit mass piracy, they're ahead of the game, probably far enough to rack up some sales. And even if their solution is a total technical crock, it's a crock a bunch of people are trying to develop, and it can be used as an argument to lawmakers that they don't need to introduce draconian new legislation to "solve" the copyright problems because we're doing it technically - though of course lawmakers have figured out that this gives them the choice between being visibly obsolete or writing clueless legislation to regulate the new technology as well as the old....

I think the point they were trying to make was the data is not left in the clear on the storage media (this is typical marketing droids at work). For practical reason data must be in the clear in memory at some point in time. Also the data must be transferred into some type of peripheral so the user can do somthing with the data (read text off a monitor, print a document, listen to music, ...ect). This is the biggest failings in these systems. Once the user has the ability to decrypt the data the game is lost. One does not need to break the crypto system as they give you the keys with the product!! Will this prevent John doe from giving a copy of the document to a friend?? Nope as he will just give the friend the passphrase (or what ever mechanism they use) along with the copy. Will this prevent the Warez groups?? It may slow them down some but it woun't get rid of them. Will it stop commercial pirating?? HAH!! It will not even slow it down, a minor inconvenience at best. - -- - --------------------------------------------------------------- William H.

Yep see Electronics and Computer Science added to the Evil Book Topic list: Evil Book Topic List ==================== Chemistry -- could be used by "Terrorist" Physics -- could be used by "Terrorist" Biology -- could be used by "Terrorist" Mathematics -- could be used by "Terrorist" Not to mention the fact that if you have any equipment related to any of these evil topics and you are not a state approved scientist automatically elevates you to either "terrorist" or drug manufacture if not both. Basically it is getting to the point where having an IQ greater than 100 is a crime (no doubt generated out of jealousy by those who work for the State).

Persistent Cryptographic Wrappers (RightsWrapper) - No matter where the digital document (financial newsletter, educational test, minutes from a court proceeding, sensitive health care records, etc.) goes, no matter how it gets there, whether it is used and then subsequently redistributed, etc. the document is always encrypted. It is never left decrypted and exposed even while it is being viewed.
They have lost their mind. Since humans are notoriously bad at performing decryptions in their head in real time, whatever is sent to the display *must* be cleartext. Any competent programmer can grab it at that point.
Undoubetedly there will be attempts to create display chips with built-in decryption and special display and/or raster/vectorizing approaches which are comfortably viewed but are difficult to snap shot using "screen shooters" or simple capture hardware. With the new USB and FireWire interface standards this isn't too far fetched. All, as you say probably doomed to failure. --Steve
