Shit, I've been tricked.

I've just bought the CD MINIMUM-MAXIMUM of KRAFTWERK

No problem to listen it on my hi-fi system, but as soon as I insert it on my PC, I get this message (same thing on Apple's OSX):


I click CANCEL (I'm not that stupid!).
And I cannot listen to the CD.

exploration of the CD:




(No trace of the audio files)

I launch my audio player MUSIKCUBE.
I try to look up for the tracks:


I try a MP3 rip to put it on my MP3 player:


conclusion:




Thanks to the DRM....


CD bought in Hongkong, with the sticker copy controlled
"This contains Copy controlled technology."

and a text indicating that "on some equipments for example car CD playback problems may be envoutered"

Don't make the same mistake as I did !

Researcher: DRM Has Deep Flaws

DRM won't protect the music and film industries from illegal file sharing, researcher says.

Digital rights management (DRM) technology has deep flaws despite the hope of content providers that encrypted files will deter illegal file sharing, a computer security researcher said Monday.

DRM is a catch-all term for a variety of methods used to limit content sharing. Techniques include digital encryption of songs and encoded limits on the number of times content can be accessed. But DRM technologies are far from foolproof, and the ones developed so far have been easily circumvented by adept hackers, said Ian Brown, a senior research manager at the Cambridge-MIT Institute in England.

DRM won't protect the music and film industries, which have spent the last decade lobbying for new laws to protect their content but neglected trying to find better ways to monetize their offerings, he said. Bands such as U2 and the Grateful Dead use their music more as a promotional tool, relying on touring and merchandise for revenue, he said.

"It's the business models that need changing, not the technology," said Brown, whose doctoral thesis in part covered DRM technologies. He spoke at the Changing Media Summit in London.

DRM technology is simple but making it work is difficult, Brown said. The data has to be decrypted to be used, and the "analog hole" remains--the ability for determined bootleggers to use a microphone or regular video camera to record content for posting on file-sharing networks.

So-called "watermarks"--instructions regulating the usage of the file that are invisible to the users--can be removed by a determined programmer, allowing them to post a file to a P-to-P (peer to peer) network, Brown said. The algorithms used for watermarks are still "primitive," Brown said.

DRM technologies may be most effective for time-based events where encryption would only have to hold for a short period, such as the broadcast of a live sports event, Brown said.

Closely Watched

The progression of DRM technology is closely watched. Music and film industry officials argue that DRM is crucial to preserving revenue in the face of piracy. Consumer advocates say DRM technologies can be too restrictive for consumers who legitimately paid for content and want to share it on several devices.

"Fundamentally, it's an anti-user technology," Brown said. "It's a technology that allows content owners to provide data to their customers with restrictions on how they can use it that aren't justified by copyright law.

Microsoft is incorporating features into its next-generation OS, Windows Vista, to take advantage of DRM capabilities of TPM (trusted platform module) chipsets. TPM chip sets have the capability to store the keys, passwords, or certificates attached to DRM-enabled files and only allow decoding by authorized users.

France is debating legislation that would require companies developing DRM technologies to provide enough information so other companies can make interoperable systems. Apple Computer has lashed out at the measure, saying it will encourage music piracy.

Et merde, je me suis fait avoir.

Je viens d'acheter le CD MINIMUM-MAXIMUM de KRAFTWERK (de chez EMI RECORD). Il passe très bien sur ma chaîne hi-fi mais dès l'insertion du CD dans mon PC(à noter qu'on a le même résultat sur OSX)j'ai ça:


(je clique non-et puis quoi encore???)
Et impossible de le lire.

exploration du CD:




(aucune trace des fichiers audios)

Je lance MUSIKCUBE.
Je tente de reconnaître les pistes via le net:



Je tente de ripper en MP3:



conclusion:



merci les DRM...


CD acheté à Hongkong, avec l'autocollant copy controlled
"ce disque contient un dispositif technique limitant les possibilités de copie."

et un texte m'indiquant "je risque de pas pouvoir le lire sur certains autoradios".

Ne vous faites pas avoir comme moi !


et regardez le site http://stopdrm.info/ en passant.

EDIT: J'ai du nouveau:

un chercheur dans le domaine de la sécurité informatique à déclaré: En dépit de l'espoir deplacé dans les DRM par les fournisseurs de contenus, les DRM ont de gros défauts et ne sont pas en mesure de mettre un terme au partage illégal de fichiers.

DRM est une appelation qui regroupe toute une variété de méthodes pour limiter le partage de contenu, parmi les techniques utilisés on retrouver le cryptage numérique de chansons et un nombre d'accès au contenu limité. Les techniologies DRM jusqu'a présent ont facilement été contournées par des personnes compétentes à déclaré cette fois un directeur de recherche de l'institut cambridge-MIT en Angleterre.

Les DRM ne protègeront pas l'industrie du disque ni l'industrie du film qui ont depuis près d'une décénnie ont misé sur le lobbying pour faire passer de nouvelles lois qui protège leurs contenus tout en négligeant de monétiser leurs offres. Des groupes comme U2 ou les grateful dead utilise leur musique comme un support promotionnel et dépendent des concerts et du merchandising pour leurs revenus.

"C'est le modèle économique qui demande à être changer, pas la technologie" à dit Brown détenteur d'une thèse dont une partie couvre les technologies de DRM. Il faisait partie des orateurs au Changing Media Summit à Londres.

Le principe des DRM est simple mais leur mise en pratique est difficile. Les données doivent petre décryptées pour être utilisables et the "trou analogique" (--la possibilité d'enregistrer la contenu via un microphone ou une caméra) est toujours présent.

Les watermarks --instructions régulant l'usage possible d'un fichier qui sont incluses dans un fichier de manière transparente -- peuvent être retirés par un programmeur déterminé pour ensuite pouvoir les partager .Les algorithmes utilisés comme watermarsk sont encore primitifs à ajouté Brown.

L'utilisation de DRM qui pourrait se révèler la plus efficace est en matière d'évènements basé sur le temps, où le cryptage n'aurait besoin que d'une courte durée de vie, par exemple la diffusion en direct d'un évènement sportif. à ajouté Brown.

La progression des technologies DRM est survéillée de près.les officiels des industries de la musique et de films prétendent que les technologies DRM sont cruciales pour préserver leur revenus mis en danger par le piratage. Les consommateurs et leurs défenseurs trouve que les technologies de DRM s'avèrent trop restrictives pour les consommateurs qui ont acheté un contenu de manière légitime et qui souhaiterait l'utiliser sur différents supports.

"Fondamentalement, c'est une technologie anti-utilisation" a dit Brown. "c'est une technologie qui permet aux propriétaires des droits d'exploitations d'un contenu de fournir au consommateur des donnés dont l'usage est restreint d'une manière qui ne sont pas justifié par les lois sur le copyright."

Microsoft intègre des fonctionnalités dans son prochain système d'exploitation pour profiter des capacités des puces TPM à gérer les DRM. les puces TPM on la capacité de stocker les clés, mots de passe et/ou les certificats associés aux fichiers enrichis en DRM et de n'autoriser le décodage de ces fichiers que par l'utilisateur autorisé.

Puis l'article se termine en parlant de l'amendement de dernière minute de la loi dadvsi sur l'interopérabilité et de la réponse d'apple.
