Abstract :
The paper proposed a new method for detecting and recovering the tampered regions of images being attacked when they were transmitting in the internet. Our scheme used the wavelet-based semi-fragile watermark, which allowed the detection of changes in the image in localized spatial and frequency domain regions. And we did research on how to recovery the forged regions effectively. According to the results, the watermarked images could be recovered successfully.
