METHOD AND SYSTEM FOR DISTRIBUTED COPY ADMINISTRATION

摘要

The invention relates to a method for administration of distributed copies of a data-item in a system comprising a device (110 - 130, 140, 145). The method comprises associating a copy of the data-item with two counters (240), one counter representing a number-of-direct-copies made from said copy (245) and one counter representing a generation-number of said copy (250). Hereby is achieved an administration of distributed copies with a reduced amount of administration, more specifically the administration of distributed copies is simplified in part, in particular with respect to the verification of whether or not gifting of a copy of a data-item in the system is permitted.
