Abstract
One or more methods of generating a pseudonymizable document are described. A method comprises receiving a set of subdocuments and generating a first set of random values wherein each subdocument in the document corresponds to a first set random value. A second set of values is generated based on a subdocument and a corresponding value of the first set random value. A set of pseudonyms is generated wherein each subdocument in the document corresponds to at least one pseudonym of the pseudonym set. A third set of values is generated based on the second set of values and the pseudonym set and a summary value is generated based on the third set of values.
