DRM stands for Digital Rights Management and TPM stands for Technical Protection Measures. Both of these are terms for “digital locks”. Digital Locks allow the manufacturer to control their product after we have bought them. Personally, I would think that a digital lock should be illegal, because once I buy something, I own it. But that’s another article.
The Canadian DMCA has just been tabled by the Conservative government. The main provision of Bill C-32 the so-called “Copyright Modernization Act” that pretty much everyone agrees is bad is that the resulting law will make circumvention of digital locks illegal.
Which got me thinking about PDFs. A PDF is a technical protection of content locked in a digital format.
I used to be simply annoyed by PDF files. If I am getting information online, I don’t think it should be necessary to download special software in order to read it. So unless I really want the information badly, I won’t. And then I won’t use the Adobe reader which alwasy seems to have security warnings about all the ways Adobe Readers allow malware to get into our computers. How do computer viruses spread? By putting insecure things in our computers.
Everyone everywhere on the internet can read files in html without having to put software they don’t want on their computer. That’s what we see when we look at web pagees, or blogs or email.
I recently learned that the reason PDFs exist is to lock the document format for printing. So really, the only reason to put your information into a PDF file is to send it to a printer. It is not the right choice for disseminating online information.
If the information is really important to me, I will use the PDF reader I have. So it is possible for me to deconstruct important information like say an ACTA leak into html so that people can read it Shine a Light on ACTA: A.C.T.A. Anti Counterfeiting Trade Agreement Unlocked Then the information can also be indexed by search engines.
But the question is:
Is a PDF DRM or TPM?
The reason people put content into a PDF file is to preserve the formatting. A PDF file uses technical protection measures to preserve the formatting. Many people have software to deconstruct PDFs, dor me, if I want to circumvent a PDF’s TPM I have to do it the old fashioned way, by re-typing it.
So if they pass Bill C-32, deconstructing a PDF will be circumventing a digital lock. It will be illegal, won’t it?
P.S. Oh look, more warnings:
