Method for identifying peripheral device from digital content
A recently granted patent (Publication Number: US11924494B2) discloses a method for identifying a peripheral device receiving digital content from a master device. The method involves generating a unique identifier for the peripheral device and the master device, watermarking the digital content with this identifier, and creating event data containing transaction information and proof of purchase. The peripheral device is connected to the master device through a wired local connection and is a rendering device. The event data can be sent to a server or stored in the master device, with the server generating a code in response to the data.
Furthermore, the patent describes a master device that transmits digital content to a peripheral device, with a data interface circuit receiving unique identifiers for both devices. The processing circuitry generates marks based on these identifiers, watermarking the content before transmission. Event data, including transaction details, is created and can be sent to the server periodically or upon request. The processing circuitry can also generate a second mark for watermarking purposes. This innovative method and device aim to enhance the identification and tracking of peripheral devices receiving digital content from a master device, ensuring secure and authorized content transmission based on transaction information and proof of purchase.
