摘要

A three-dimensional position information generation unit (210) generates three-dimensional position information using measured data acquired by a measurement instrument (201). An additional information acquisition unit (220) acquires, as additional information, at least any one of authenticated user information, instrument information, and measurement information. An information encryption unit (231) encrypts a set of the generated three-dimensional position information and the acquired additional information.
