Data utilization device, data utilization program and data utilization method

摘要

Problem to be solved: to provide a data utilization device capable of inhibiting utilization of data obtained by another user.The synthesizer 50 attempts to copy the sound data from the external recording media 45 (S11: Yes), and the user's key that has purchased the sound data is Whether or not the user key of the user key memory 52b of the synthesizer 50 coincides with each other (S14).When the user key does not match (S14: no), an instruction is made to delete the user key of the user key memory 52b (S15).When the user key is deleted, the sound data stored in the synthesizer 50 is also deleted (S4).Thus, it is possible to prevent the user from storing the sound data obtained by the user other than the user possessing the synthesizer 50 in the synthesizer 50.Diagram
