Identification assistance data generation technology and identification information extraction technology

摘要

PROBLEM TO BE SOLVED: To surely extract unique data from a target even in a situation where an ID or the like is not attached to the target. In the first phase, a step of acquiring an input vector representing each of a plurality of objects and a space including the input vector are included in different subspaces so that the input vector representing each of the plurality of objects is included in the different subspaces. It includes steps to generate a plurality of hypersurfaces that are divided and used to generate a unique vector that identifies each of the plurality of objects. In the second phase, a step of acquiring a vector representing a specific object included in a plurality of objects and a space including the vector are divided and held in advance so that each of the plurality of objects is included in a different subspace. It includes a step of generating a vector that identifies a specific object by evaluating a vector that represents a specific object using a plurality of hypersurface surfaces.
