Abstract: A method for verifying the integrity of data in a message by a data processing device, the message comprising a plurality of packets, the method comprising: receiving, at the device from a first resource, a manifest associated with the message, the manifest comprising a plurality of group check values for the plurality of packets; receiving, at the device, from the first or a different resource, the message; generating a first progression of rolling hashes for the plurality of packets; deriving group check values from the first progression of rolling hashes for groups of the plurality of packets along one or more paths; verifying the integrity of the data in the message based on or in response to a determination that the derived group check values correspond to the plurality of group check values in the manifest.

Abstract: A machine-implemented method or data processing component for controlling the processing of digital content from plural sources by at least one data processing device comprises receiving at least two digital content manifests at the data processing device; receiving at least one digital content payload at the data processing device; and responsive to the at least two digital content manifests, performing an atomic action using the at least one digital content payload.
