In recent years, technological developments have led to digital files being more easily
distributed, for example through Napster (a file sharing service on the Internet). In
order to manage and control the distribution of digital files, a new concept has been
developed, called DRM (Digital Rights Management). The purpose is to set every
single file with individual rights that are extremely hard to break, and consequently
make people pay and use the files legally. The file will then be fully protected from
intrusion and alteration until the set rights expire.
The goal of this thesis is to look into and summarise DRM of today. We have
concentrated on the mobile DRM market, and especially mobile phones. Especially
the solutions/applications that already exist and their functionality and properties, but
also requirements regarding security levels, compatibility etc. We have also added
predictions of the near future, ours as well as others.
Existing applications for DRM are well made but few are constructed for mobile
phones. Mobile phones will however be a good and secure platform for DRM. At
present there is no DRM application inserted in mobile phones in Europe. The third
generation (3G) network will push the progress with the capability of broader
bandwidth, with capacity of downloading more content to the phone.
Since the mobile phone software is embedded and the mobile phones are within a
trusted network, the security level of a DRM application in a mobile phone can be
discussed. A lower level of security would make it easier for managing content but
also open up the market for hackers that wish to trespass. With a lower level of
security you always have to consider the consequences and often it creates more
problems than it solves.
We believe the DRM market and its value will increase exponentially over the next
few years. The number of players on the mobile Internet DRM market will be less
than on the Internet DRM market, due to the complexity of getting applications into
the phone. The latter will consist of many more players, and remain fragmented, since
it is an open market.
