Abstract

Digital watermarking is a technology of embedding watermark with intellectual property rights into images, videos, audios and other multimedia data by a certain algorithm. The basic characteristics of digital watermark is imperceptible, security, reliability, low complexity of watermarking algorithm and security of the hiding place. Digital watermarking algorithm is composed of three parts: watermark embedding algorithm, the watermark extraction algorithm and the watermark detection algorithm.Future research of digital watermarking technology will focus on the watermarking algorithm, the study of watermarking theories, the watermark attacks and the evaluation system of watermarking system.
