抄録

In this technical report, we propose a method of digital watermarking for airborne laser scanner data. Our method is executed in two steps. In the first step, the area in which we bury digital watermarking is selected by a method of using entropy. In the second step, digital watermarking is buried in the selected area. At this time, the error margin caused by burial of digital watermarking is reduced by using mode filter. Through the experiments using DSM (Digital Surface Model) data, we demonstrate the effectiveness of our method.
