Linking encrypted datasets using common identifiers
Abstract:
A device, system and method for linking encrypted data sets using common encrypted identifiers in encrypted space. A first and second parties' encrypted data sets may include first and second respective encrypted data and associated first and second respective encrypted identifiers. The first and second encrypted identifiers may be converted into a first and second respective sets of a plurality of elemental identifier components. Each of the plurality of elemental identifier components in each component set characterizes a distinct numeric property of the corresponding converted encrypted identifier. The first and second sets of the plurality of elemental identifier components may be composed, component-by-component, to generate a plurality of component-specific results. If the plurality of component-specific results are determined to satisfy a matching criterion indicating that the first and second encrypted identifiers match, the first and second encrypted data associated with the first and second matching encrypted identifiers may be linked.
