发明名称 SYSTEM TO ALLOW CONTENT SHARING
摘要 The present invention relates to a method and a system for converting digital rights. The invention is based on the idea that a mechanism is introduced, by which it is possible to convert an unlimited right into at least one limited digital right, which gives a user access to the content a limited number of times. The present invention is advantageous since if a proprietor of an unlimited right wants to share his/her unlimited right with a friend, he/she does not have to give up the unlimited right to the friend. If the proprietor would like to share the right with other content consumers, the unlimited right can be converted into a number of limited rights, wherein these limited rights can be shared with the other content consumers.
