Abstract
A method begins by a processing module processing a data retrieval request that identifies data, wherein the data is stored as a plurality of sets of encoded data slices, wherein one or more encoded data slices of the plurality of sets of encoded data slices has been replaced with one or more encoded secret slices of secret data. The method continues with the processing module receiving at least a threshold number of the plurality of sets of encoded data slices and determining whether a secret data extraction process is initiated. The method continues with the processing module obtaining an inter-dispersing function to extract the one or more encoded secret slices to produce extracted encoded secret slices and decoding the extracted encoded secret slices in accordance with secret dispersed storage error encoding parameters to reproduce the secret data when the secret data extraction process is initiated.
