Abstract
A method begins by a processing module receiving a plurality of requests to record a broadcast of data. The method continues with the processing module encoding 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 request of the plurality of requests. The method continues with the processing module generating a unique retrieval matrix for each of the plurality of requests based on an identity of a requesting device and the error coding dispersal storage function to produce a plurality of unique retrieval matrixes. The method continues with the processing module storing the plurality of sets of encoded data slices and the plurality of unique retrieval matrixes in a dispersed storage network memory as a plurality of unique copies of the data.
