<p>PROBLEM TO BE SOLVED: To provide an encryption method for simple image transmission with high security by using partial correlation between different images. SOLUTION: An original image A to be sent to a transmitter side and a reference image B that is an entirely different image from the image A are prepared, and the original image A is coded and transmitted by using partial correlation between the different images, that is, the original image A and the reference image B. Then a receiver side reproduces information that is coded and transmitted while referencing the reference image B at hand.</p> |
