Multi-Purpose Image Watermarking Method Based on Wavelet Transform

Recently, many image authentication methods are proposed, but most schemes focused on one purpose. In this paper, we propose a multi-purpose image authentication method that embeds authentic information and a watermark into the wavelet domain. This method is tolerant to JPEG and JPEG2000 compression, but sensitive to malicious attacks. At the same time, this method can verify the ownership and identify the original owner. Our experiments demonstrate that this multi-purpose image authentication method can achieve semi-fragile image authentication and copyright protection.
