Abstract
Non-informational data D is generated as an output using a non-informational data E and informational data as inputs to a function on a computing device in an information- restricted domain. The function may be an XOR and the non-informational data E may be a pseudorandom string of the same length as the informational data. The non-informational data D is moved to an unrestricted domain where it may be managed normally. When the informational data is needed it can be re-generated using the non-informational data D and non-informational data E as inputs to an inverse function (XOR is its own inverse). The non-informational data E may be generated from a smaller random seed.
