摘要： The invention relates to a method for supplying a virtual product to a third party, said product being in a digital form in an original version (300) and having a pre-determined level of quality. According to said method, a reduced version (308) of the virtual product together with information (310) relating to a distributor of the virtual product is provided. The quality of said reduced version (308) is lower than the quality of the original version (300), and the information relating to the distributor is associated with said reduced version. Other information can be produced on the basis of the information (310) associated with the reduced version (308). Said other information indicates that the reduced version has been distributed to the third parties by the distributor. The other information is produced if the third party has obtained rights on the reduced version after receiving the same.

摘要： The invention relates to a device for testing a dataset (112), said data set (112) having a plurality of subsets and one partial test value (114) per subset. The inventive device comprises a facility (102) for establishing a test value and a comparative facility (103). The facility (102) for establishing a test value is adapted to establish, based on the partial test values (114) of the subsets, a common test value (116). The comparative facility (103) is adapted to compare the common test value (116) with a comparative value (118) provided to the comparative facility (103).
