Abstract
Ever since the digital revolution allows us to convert and digitalize almost any media into the form of bytes and bits, it is also fairly easy to copy these digital materials. The Internet itself has greatly eased the legal or illegal distribution of such media. Although it is not easy to change the “all for free” habit of the average Internet user today, in the world of mobile telephony subscribers have gotten used to pay for contents or services from the very beginning. For this reason there might be a chance to convince these users to pay for copyrighted materials. As the world of mobile telephony and the Internet is getting closer and closer today, and more valuable services and contents emerge, the technical protection of copyrighted materials is getting into view.
On the summer of 2004, SEARCH-LAB Ltd. and the Budapest University of Technology and Economics (BUTE) carried out a project named Digital Rights Management of Mobile Applications. The goal of the project was to develop a mobile phone based payment system, that is easily configurable to different price and service categories. With the use of such a payment system, the authors of copyrighted digital contents could easily protect their rights for a given object, without the need to develop a proprietary solution.
The goal of this thesis is to describe the various methods and techniques of digital rights management, and to present the server-side applications developed during the project mentioned above.
