1. A data transform system comprising:

  • a processor;

    a memory connected to the processor, storing a collection of data; and

    a data transform module, accepting a usage constraint, a privacy constraint and the collection of data from memory, the data transform module transforming the collection of data according to the usage constraint and the privacy constraint,wherein the usage constraint defines a subset of the collection of data, andwherein the data transform module suppresses the subset of the collection of data according to the privacy constraint, the privacy constraint defining a minimum number of entities in a subset of the collection of data, wherein any combination of all values of a suppressed collection of data output by the data transform module can be narrowed to the subset having at least the minimum number of entities in the collection of data.
