发明名称 SECURE SUPER DISTRIBUTION OF USER DATA
摘要 The invention refers to a method for secure super distribution of user data stored on a first data carrier comprising the steps of a) copying said user data from said first data carrier to a second data carrier; b) storing on said second data carrier information that is required by a service center for granting access rights to said copy of said user data; and c) obtaining access rights to said copy of said user data by transmitting at least said stored information to said service center, completing a transaction, and receiving additional access information; characterized in that said service center uses said stored information to grant access rights to said copy of said user data for said second data carrier. Thus copy control is performed over access-controlled content. Additionally, benefits can be given to the owner of original data carriers. The invention also refers to a system for secure super distribution, an apparatus for reproduction and/or recording of user data and to a data carrier.
