Abstract

A processing module of a dispersed storage network determines an obfuscation method is determined from a plurality of obfuscation methods for a data segment. The method continues with the processing module obfuscating the data segment according to the obfuscation method to produce an obfuscated data segment. The obfuscated data segment is encrypted and dispersed storage error encoded to produce a set of encoded data slices. The set of encoded data slices is then transmitted for storage in the dispersed storage network.
