Gestão de direitos digitais (DRM em inglês)

Digital rights management (DRM) is a generic term for access control technologies that can be used by hardware manufacturers, publishers, copyright holders and individuals to try to impose limitations on the usage of digital content and devices. It is also, sometimes, disparagingly described as Digital Restrictions Management. The term is used to describe any technology which inhibits uses (legitimate or otherwise) of digital content that were not desired or foreseen by the content provider. The term generally doesn’t refer to other forms of copy protection which can be circumvented without modifying the file or device, such as serial numbers or key-files. It can also refer to restrictions associated with specific instances of digital works or devices. DRM technologies attempt to control use of digital media by preventing access, copying or conversion to other formats by end users. See wikipedia.

Quais as consequências do DRM para mim?

When you buy an e-book with DRM you don’t really own it but have purchased the permission to use it in a manner dictated to you by the seller. DRM limits what you can do with e-books you have «bought». Often people who buy books with DRM are unaware of the extent of these restrictions. These restrictions prevent you from reformatting the e-book to your liking, including making stylistic changes like adjusting the font sizes, although there is software that empowers you to do such things for non DRM books. People are often surprised that an e-book they have bought in a particular format cannot be converted to another format if the e-book has DRM. So if you have an Amazon Kindle and buy a book sold by Barnes and Nobles, you should know that if that e-book has DRM you will not be able to read it on your Kindle. Notice that I am talking about a book you buy, not steal or pirate but BUY.

O que faz o DRM pelos autores?

Publishers of DRMed e-books argue that the DRM is all for the sake of authors and to protect their artistic integrity and prevent piracy. But DRM does NOT prevent piracy. People who want to pirate content or use pirated content still do it and succeed. The three major DRM schemes for e-books today are run by Amazon, Adobe and Barnes and Noble and all three DRM schemes have been cracked. All DRM does is inconvenience legitimate users. It can be argued that it actually harms authors as people who would have bought the book choose to find a pirated version as they are not willing to put up with DRM. Those that would pirate in the absence of DRM do so in its presence as well. To reiterate, the key point is that DRM does not prevent piracy. So DRM is not only pointless and harmful to buyers of e-books but also a waste of money.

DRM e liberdade

Although digital content can be used to make information as well as creative works easily available to everyone and empower humanity, this is not in the interests of some publishers who want to steer people away from this possibility of freedom simply to maintain their relevance in world developing so fast that they cant keep up.

Porque é que o Calibre não suporta DRM?

calibre is open source software while DRM by its very nature is closed. If calibre were to support opening or viewing DRM files it could be trivially modified to be used as a tool for DRM removal which is illegal under today’s laws. Open source software and DRM are a clash of principles. While DRM is all about controlling the user open source software is about empowering the user. The two simply can not coexist.

Qual é a posição do Calibre sobre fornecedores de conteúdos?

We firmly believe that authors and other content providers should be compensated for their efforts, but DRM is not the way to go about it. We are developing this database of DRM-free e-books from various sources to help you find DRM-free alternatives and to help independent authors and publishers of DRM-free e-books publicize their content. We hope you will find this useful and we request that you do not pirate the content made available to you here.

Como posso ajudar a luta contra o DRM?

As somebody who reads and buys e-books you can help fight DRM. Do not buy e-books with DRM. There are some publishers who publish DRM-free e-books. Make an effort to see if they carry the e-book you are looking for. If you like books by certain independent authors that sell DRM-free e-books and you can afford it make donations to them. This is money well spent as their e-books tend to be cheaper (there may be exceptions) than the ones you would buy from publishers of DRMed books and would probably work on all devices you own in the future saving you the cost of buying the e-book again. Do not discourage publishers and authors of DRM-free e-books by pirating their content. Content providers deserve compensation for their efforts. Do not punish them for trying to make your reading experience better by making available DRM-free e-books. In the long run this is detrimental to you. If you have bought books from sellers that carry both DRMed as well as DRM-free books, not knowing if they carry DRM or not make it a point to leave a comment or review on the website informing future buyers of its DRM status. Many sellers do not think it important to clearly indicate to their buyers if an e-book carries DRM or not. Here <> you will find a Guide to DRM-free living.
