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: In one example, a method includes obtaining, by a data processing device, first secret data associated with a first user and corresponding to a first location of a remote resource. The method further includes generating, using the first secret data, a first uniform resource locator (URL) usable to obtain the first location, and accessing the first location using the first URL. The method further includes obtaining, in response to transfer of usage rights of the data processing device from the first user to a second user, second secret data associated with the second user and corresponding to a second location of the remote resource. The method further includes generating, using the second secret data, a second URL usable to obtain the second location, and accessing the second location using the second URL. The second location is inaccessible via the first URL. The first location is inaccessible via the second URL.
