Claim 11:
12. A master device that transmits a digital content to a peripheral device, the master device being separate from the peripheral device and configured to be connected to a server, the master device comprising:
a data interface circuit configured to receive, from the peripheral device that receives the digital content from the master device, at least a peripheral identifier that uniquely identifies the peripheral device that receives the digital content from the master device; and
processing circuitry configured to
generate, at the master device that sends the digital content to the peripheral device, a first mark as a function of:
the peripheral identifier that uniquely identifies the peripheral device that receives the digital content from the master device,
a master device identifier that uniquely identifies the master device that sends the digital content to the peripheral device, and
transaction information related to the digital content;

watermark, at the master device that sends the digital content to the peripheral device, the digital content using the first mark before transmitting the digital content to the peripheral device; and
generate, at the master device that sends the digital content to the peripheral device, event data that includes at least the master identifier that uniquely identifies the master device that sends the digital content to the peripheral device, the transaction information related to the digital content, proof of purchase of the digital content, and a date of the transaction information,
wherein the peripheral device that receives the digital content from the master device is connected to the master device that sends the digital content to the peripheral device through a wired local connection, and the peripheral device that receives the digital content from the master device is a rendering device.
