摘要

A two-dimensional bar code generating apparatus 10, the original generator 12 on the basis of the published procedures, to generate original bar code 40 that has two-dimensional bar-coded information to be transmitted, a key for generating a key image 52 I includes a generator 16, and a message generator 14 for generating a transmission image statement 45 encrypted by the action of the key image 52 in the original bar code 40.
