Method and system digital for processing digital content according to a workflow

摘要

A method of processing digital content according to a workflow. The digital content is received and information for the workflow is checked to decide if a processing device is authorized to process the content, the workflow imposing that the digital content be processed in a process chain comprising at least two nodes, wherein the processing device is authorized to process the content if it corresponds to the node that according to the process chain is the next node to process the digital content. If the processing device is authorized to process the content, the digital content is processed and the information for the workflow is updated. Also provided is a system.

1. A method of processing digital content according to a workflow, the method comprising, at a hardware processing device,
(a) receiving, by the hardware processing device comprising a processing device identifier, a content file including the digital content, an identifier of a device that most recently processed the digital content and a header; (b) sending, by the hardware processing device, to a second device a content identifier for the digital content, the identifier of a device that most recently processed the digital content and the processing device identifier; (c) receiving, by the hardware processing device, a response signal from the second device authorising the hardware processing device to process the content, the authorization based on workflow auxiliary information for the digital content corresponding to the content identifier, wherein the workflow auxiliary information comprises at least one action that may be applied to the digital content by the hardware processing device and a determination that the processing device identifier corresponds to an identifier of a device following the device that most recently processed the digital content in the workflow; and if the hardware processing device is authorized to process the content:
d1) receiving a decryption key for the encrypted digital content;d2) decrypting the encrypted digital content;d3) processing, by the hardware processing device, the decrypted digital content resulting in a modified digital content called processed digital content; andd4) re-encrypting the processed digital content.
