    摘要: A computer includes an interface and a processing module. The processing module receives, over time and via the interface, requests to playback recorded broadcast data, wherein a single copy of the recorded broadcast data is dispersed error encoded to produce a plurality of sets of encoded data slices that is stored in a dispersed storage network (DSN). In response to the playback requests, the processing module identifies unique combinations of at least a threshold number of encoded data slices for sets of the plurality of sets of encoded data slices to produce unique copies of the recorded broadcast data. For a particular playback request, the processing module retrieves a unique copy of the unique copies of the recorded broadcast data from the DSN and outputs, via the interface, the retrieved unique copy to a device associated with the particular playback request.

    摘要: A method begins with a processing module obtaining encoded key slices from a plurality of user devices and decoding a threshold number of the encoded key slices utilizing a first error coding dispersal storage function to produce a key when the threshold number of the encoded key slices has been obtained. The method continues with the processing module receiving encoded data slices and decoding a threshold number of encoded data slices utilizing a second error coding dispersal storage function to produce encrypted data when the threshold number of the encoded data slices has been received. The method continues with the processing module decrypting the encrypted data utilizing the key and an encryption function to produce data.
