Abstract
A method begins by a set of storage units of a dispersed storage network (DSN) receiving a set of access requests from a requesting device. The method continues with a first storage unit extracting a unique identifier from a first access request, performing a deterministic function on the unique identifier to produce a first obfuscated identifier, seeking a first obfuscated access permissions list, recovering first access permissions from the first obfuscated access permissions list, and processing the first access request based on the recovered first access permissions. The method continues with the requesting device receiving a set of access responses from the set of storage units for the set of access requests for which the requesting device had favorable access permissions with at least a threshold number of storage units.
