Research of digital semi-fragile watermarking of remote sensing image based on wavelet analysis

In this paper, we present a novel semi-fragile watermarking scheme based on wavelet packet. The method in the paper includes four parts: first, to produce watermark; second, to scramble watermarking image; third, to embed watermark; last, to inspect and locate tampered marked image. To inspect whether including watermark in an image with the key attained from process of embedding watermarking. If it is a marked image, then extracting watermarking. At last to validate the degree of robustness by compression and noise, to locate tamper by cutting and altering.
