I just posted the article Researchers develop fingerprint forensics as DRM replacement.

 Academics  at the University of Maryland's A. James Clark School of Engineering have been  working on a digital fingerprinting technology which aims to protect music,  video, images and certain...

And if someone stole it?:S

While this may discourage the user from sharing their content online, unfortunately it also means they will need to treat all their AAC protected content as they would with confidential documents!
Result: no one would buy this, affraid of the problems inerent :r

even though those who developed in place of drm, it will be used for drm. the whole point of making the signature (watermark, digital fingerprint, or whatever) is to identify whether the source is legit or not. the signature will be compared with the user id or the player id, then they will be played. no matter the licensee would be punished, mpaa or iraa would be pissed if their “properties” are floating around the world. although they stated as if it is impossible to remove the signature, there are low tech ways to remove them unless the signature signal is very strong which will also cause degration in quality of the media stream.

So… give DRM the finger? :+

Say in theory to implement this policy effectively, we would need to chain some 650 million policemen to every computer that is capable of using the internet, or a phone home intel TPM chip,(given existing ic chip production facilities world wide, to implement this policy would need a ten year lead time minimum) Oh ,onward and upward does this propaganda fly, where it stops, and where it goes, only the deaf blind and dumb DRM guru knows!:X

  1. I don’t think that this “locks” the person into only using on one or two or five pieces of equipment, the owner can use it on any machine anywhere. This “DRM” will only point to who the original owner is if it were to be found that it was used for piracy purposes. 2) I do not think this will be of much effect because if someone buys one of these discs, plays it once, it gets tied to his/her machine, then he/she thinks the content was rubbish, sells it on Ebay. The buyer then uses it to pirate the software, the authorities find out who the original owner was and goes after him/her. The owner proves that he/she sold it on ebay, end of story. The owner should be let off the hook. If the owner sold it at a flea market, then oh well, the authorities will have to figure out something because the owner did nothing wrong, been to plenty of flea markets where used software, videos and music CD’s were for sale this DRM should not change that. 3) Sounds like this will require some kind of hybrid CD/DVD that will allow one write of the serial number of the device that it is first played on. So I don’t see this technology going too far, but as far as DRM’s go, this is probably the least intrusive and probably the best way to do it, although it will be unenforceable by the MPAA and the RIAA and that’s why it will not happen. :B Here’s an enhancement feature: Force the disc to require owners to enter their full names and addresses which will be used for the watermark. I am sure the majority of people will be honest and enter their true names and addresses, only pirates would enter false information. :wink:

“Here’s an enhancement feature: Force the disc to require owners to enter their full names and addresses which will be used for the watermark” that’s what drm is all about; you pay, then you download the contents with your signature. the difference is that today’s drm relies on the encryption of the contents with your signature, but the digital finger print adds one more layer of “protection” against piracy. even after the decryption of the contents; your name will be all over the places; thus, they hope this would be used to bring the “justice” with the digital printer print technology, hackers not only have to find either keys or short cut to break encryption, they would have to remove the digital fingerprint which would be really difficult to do in honest way (mathematically sounding way :wink: ) bd/hd dvd employ similar systems; each disks’ contents are encrypted with different keys (even among same titles) the decryption keys are not stored in the player either; they would have to be downloaded from the net although first few years, it would not be required. audio contents were to be water marked…at least that’s what i heard; thus, the player will not play any disks with water mark without the authentication. i am afraid that even on pc, we might not be able to run programs without authentications (or activations)

Speaking as a security specialist, I can assure you that security has to be reasonably harassment free or it will be ignored. That oh-so-obvious tenet dooms this effort to failure (as it does most DRM schemes).

When will they learn that the thieves are always one step ahead. :d All these attempts to protect content will end up costing millions and will fail eventually if not upon release. But anyways, who would want to copy the crap that comes out today anyways? Most of the movies and music I have seen or heard in the past couple of years has totally sucked. :r Just my two cents! :X
