摘要

The three-dimensional position information generation unit 210 generates three-dimensional position information using the measurement data acquired by the measurement device 201. [ The additional information acquisition unit 220 acquires, as additional information, at least one of the authentication user information, the device information, and the measurement information. The information encryption unit 231 encrypts the generated set of three-dimensional position information and the obtained additional information.
