A GeOMETRIC ATTACKS Robust Image Watermarking Based On DWT Domain Features

摘要

The multi-channel watermarking framework which we have proposed can resist geometric attack efficiently. In this paper, a novel image watermarking scheme using feature points based on the multi-channel watermarking image framework is proposed, which is mainly used to resist geometric attacks. This watermarking scheme generates the watermarking templates in the local feature regions of one channel data's DWT (Discrete Wavelet Transform) domain and embeds the watermarking templates in the local feature regions of another channel data's DWT domain. Self-synchronization can be obtained in the procedure of detecting watermarking, because both the watermarking templates and watermarking image undergo a similar geometric attack. Experimental results demonstrate that this watermarking scheme is robust to lots of geometric attacks and signal processing such as geometric distortion, rotation, JPEG compression and adding noise ect.
