Abstract
A system produces certified content by receiving original content acquired from a content acquisition device and receiving a device identity associated with the content acquisition device. The system produces a certification value indicating the original content was acquired from the content acquisition device having the device identity. The system associates the certification value to the original content to produce certified content that can be verified to represent the original content that was acquired from a content acquisition device having the associated device identity while preventing modification to the original content by processing not associated with certification processing. This process is performed in an uninterrupted manner to ensure certified content reflects an accurate device identity. The system can be implemented entirely within a content acquisition device itself, or in a computer system coupled to a content acquisition device.
