CONTENT DATA PROTECTING SYSTEM, OUTPUT DEVICE WITH PROTECTING FUNCTION, PRINTER WITH PROTECTING FUNCTION, CONTENT DATA PROTECTING PROGRAM, AND CONTENT DATA PROTECTING METHOD

摘要

PPROBLEM TO BE SOLVED: To provide a content data protecting system suitable for protecting content data. PSOLUTION: A host terminal 100 generates print data 400 including a user ID of a user requesting content data, a content ID of the content data, and printing of the content data, and transmits the generated print data 400 to a printer 200. The printer 200 acquires the content ID and user ID from the print data 400 when receiving the print data 400, and determines whether a user is the user with an authority for printing by the one's own printer 200 or not on every segmental area of the content data included in the print data 400 on the basis of the acquired content ID and user ID, and print restriction information 460. When it is determined that the user is not the user with the printing authority, printing of the segmental area is restricted. PCOPYRIGHT: (C)2006,JPO&NCIPI
