    摘要： A method for securely distributing a profile within a dispersed storage network (DSN) that begins by encrypting a profile using a key. The method continues by encoding the encrypted profile in accordance with a dispersed storage error encoding function. The method continues by outputting the set of encoded profile slices to the DSN for storage therein. The method continues by encoding the key in accordance with an error encoding function and outputting the set of secure key portions to a set of devices of the DSN for storage therein. A device obtains the profile by retrieving secure key portions from the set of devices and recovering the key therefrom. The device then retrieves encoded profile slices from the DSN and decodes them to recover the encrypted profile. The device then decrypts the encrypted profile using the key to recover the profile.

    摘要： A method begins with a processing module of a centralized digital video storage (DVS) system regarding recording of multi-media content that is to be broadcast at a particular broadcast time, determining a number of subscriber devices that have selected to record the multi-media content. At the particular broadcast time, the method continues with the processing module receiving the multi-media content as it is being broadcast. When the number of subscriber devices is less than a first value, the method continues with the processing module encoding the multi-media content using first level encoding parameters to produce sets of first level encoded data slices for storage. When the number of subscriber devices is equal to or greater than the first value, the method continues with the processing module encoding the multi-media content using second level encoding parameters to produce sets of second level encoded data slices for storage.

    摘要： A method begins by a computing device of a dispersed storage network (DSN) encoding digital content into a plurality of sets of encoded data slices and generating at least one set of write commands, where a write command includes an indication of a number of copies of an encoded data slice to be stored. The method continues by a set of storage units of the DSN storing the plurality of sets of encoded data slices, where a storage unit stores the number of copies of the encoded data slice in accordance with the write command. The method continues by the set of storage units receiving a plurality of retrieval requests from a plurality of requesting computing devices regarding the digital content and fulfilling the plurality of retrieval requests utilizing various combinations of copies of encoded data slices of the plurality of sets of encoded data slices.

    摘要： A method begins with a processing module of a centralized digital video storage (DVS) system storing, for playback, a plurality of sets of encoded data slices in storage units, where multi-media content is encoded to produce the plurality of sets of encoded data slices. The method continues with the processing module monitoring the storage units for a failure mode and monitoring a number of subscriber devices requesting playback of the multi-media content. The method continues with the processing module determining whether a sufficient number of unique combinations of a decode threshold number of encoded data slices per set of slices exists to service playback of the multi-media content. When the sufficient number of the unique combinations do not exist, the method continues with the processing module reassigning unique combinations of the decode threshold number of encoded data slices per set of encoded data slices to some of the subscriber devices.

    摘要： A method begins by a processing module of a dispersed storage network (DSN) retrieving a decode threshold number of encoded data slices of a set of encoded data slices from a first grouping of storage units of the DSN. The method continues with the processing module determining a first status level indication of the retrieved decode threshold number of encoded data slices and sending check status request messages to a second grouping of storage units of the DSN. The method continues with the processing module receiving check status response messages and processing the check response messages to produce a second status level indication. When the second status level indication is substantially equal to the first status level indication, the method continues with the processing module indicating that the decode threshold number of encoded data slices is of a common status level as other encoded data slices of encoded data slices.
