Abstract
A generation apparatus converts a received key to an encoded key by using an encoding function of an error correcting code, and generates a sketch by applying a first composite transformation on received fuzzy data and the encoded key. A reconstruction apparatus receives a first sketch and a second sketch, generates a composite sketch by applying second composite transformation on the first and second sketches, and reconstruction calculates difference between the two keys used to generate the first and second sketches based on the composite sketch.
