Introduction
to Digital Media Copy Protection
In the age of the internet everything is digital.
Music, books, and movies can all be compressed digitally and passed around
without the knowledge of their owner. The internet and file sharing has changed
the face of copyrighted media. The
biggest problem with digital media these days is piracy. The internet has been
a big player in the digital media revolution. With the rise and fall of
Napster, the music industry has found out the hard way how not to market its
products. Once Napster was shot down, another file sharing network popped up to
take its place. The music industry is fighting a never-ending battle with these
music pirates. The business side
of the music industry says no business model can compete with free. Even with
the MP3 revelation of the file sharer, the recorded music industry receives 32
billion dollars a year in revenue [1]. After the success of Napster peer to peer group stopped just
sharing only music and broadened their scope to anything digital. A person with
an internet connection can go and download movies, books, and even expensive
applications off these file sharing groups.
The increasing
speed of internet connection and the decrease in the price of memory storage is
also a big reason why file sharing has grown so rapidly [2].
The solution that
these media producer have come up with is to use digital media rights
management technologies to protect their products [4]. These
technologies make it more complicated for the user to use the products they
buy. These technologies have never existed before on bound books and compact
discs [4].
Most people would
think that laws would be made to protect these industries livelihoods. The laws
have been made but they are so complex that even lawyers don’t comprehend them [4]. The problem here
is between the producers who want to be paid for their work and the digital industry
that does not want to stop meaningful invention.
The courts have
made many opinions on this subject. They have decided that if the digital media
is stored on a server that is owned by the file sharing network then it is
illegal. The way peer to peer groups get around is by a big loophole. The newer
file sharing networks are just software that enable
computers to connect to each other with no middleman servers owned by the
company that produce the software.
Figure 1. Napster and Lime wire websites [5] [6]
Napster has changed its ways after being shut down in
the late 1990s. It is now a pay-per-song downloading service that allows artist
to get paid for their work. Lime wire on the other hand is a peer to peer group
where a user can download any digital media that can be found on the computers
connected to the network for free.
Benefits of
Digital Media Copy Protection
The benefits of digital
media copy protection are only for the maker of the media. With useful right
management software most pirating could be eliminated. With most file sharing
eliminated there would be no option but to buy the media from the people who
produced it. This would put the market the way it once was before the internet
came along and changed everything. The producers of media are always scared
that a new way of doing things will change their industry. When the radio came
around the music industry though there job would be over [3]. This obviously
did not happen. There will always be people who are going to pay for everything
and the media producers will not suffer from copyright violations. There will
always be people who are going to copy tapes, burn CDs, and download music so
the music industry should just put their concerns away and keep producing
because the bottom lines are not getting any smaller no matter what new
technologies bring.
There are plenty of
ethical issues associated with digital media copy protection. When digital
media is downloaded it is like stealing from the manufacturer. Artists don’t
get paid for work that is downloaded. You can’t will stealing
of digital media to be universal, so it is immoral. Not that it being immoral
stops anyone from doing it.
Problems
with Digital Media Copy Protection
The problem with right management software is that as
soon as it is released a hacker has already broken the code and it is free and
open to the public again. All it takes is one open copy spread over the
internet to turn into millions of free copies for the file sharing public.
In 1998 the
Digital Millennium Copyright Act (DMCA) made it illegal to produce any software
that would make copy protection software not work correctly. If a copy
protection software is broken and the producer finds out who broke the code, it
could not only sue for stealing the media but for breaking the code in the
first place [4].
Digital media copy protection also keeps useful
products off the market because they could be used for file sharing purposes.
Companies who produce media could avoid all digital
media copy protection problems if they put a reasonable price on the media they
make. In the case of music downloads most song on pay service cost about 99
cents per song. If you look at the price of a compact disc it is about 15
dollars, which would also be about a dollar per song. But wait, the music
company did not have to produce the round discs and the various papers that
come with them. They did not have to ship the CDs all over the world to stores
where they could be sold. The songs are just created and put on a server to
sell. This has to cost less then the alternative. If it was cheaper, say 25
cents per song, many more users would drop there file sharing ways in order to
get better quality music and not have to worry about the FBI knocking on their
door. I know that the music industry says nothing can compete with free, but if
the price and profits were more reasonable more people would be willing to pay.
