Watermark A visible or invisible signature embedded inside an image to show authenticity or proof of ownership. The hidden watermark should be inseparable the host image, robust enough to resist any manipulations while preserving the image quality. Thus through watermarking, intellectual properties remains accessible while being permanently marked.
