Abstract:
1. A memory device that stores operational instructions that, when executed by a processing module, causes the processing module to: receive a plurality of record requests to record a broadcast of data; encode the data using an error coding dispersal storage function to produce a plurality of sets of encoded data slices when the data is broadcast and in response to a record request of the plurality of record requests; generate a list of requesting device identities corresponding to the plurality of requests; store the plurality of sets of encoded data slices and the list of requesting device identities in a dispersed storage network (DSN) memory; receive a playback request from a device identified in the list of requesting device identities; generate a unique retrieval matrix for the device based on the error coding dispersed storage function; and output a unique plurality of sets of encoded data slices from the plurality of sets of encoded data slices in accordance with the unique retrieval matrix.
