US Patent 11074234 Data space scalability for algorithm traversal

A system for data space limitation includes and interface and a processor. The interface is configured to receive a structured data set. The processor is configured to determine a whole data space for the structured data set; remove duplicate pairs from the whole data space to generate a duplicate pair limited data space; remove hierarchical redundant pairs from the duplicate pair limited data space to generate a redundant pair limited data space; remove user settable combinations from the redundant pair limited data space to generate a user settable combinations limited data space; remove privacy preserving combinations from the user settable combination limited data space to generate a privacy preserving combinations limited data space; remove access prohibited combinations from the privacy preserving combinations limited data space to generate an access prohibited combination limited data space; and provide the access prohibited combination limited data space for combination calculation.
