Abstract Digital image watermarking belongs to the branch of information hiding discipline, the study of the digital watermarking will play an invaluable role in the integrity of business transactions and the protection of personal privacy.This paper introduce the embedding process of digital watermarking technology and the extraction process of digital watermarking technology. We analyze the the characteristics of digital image watermarking and juxtapose the basic principle of the Lease Significant Bits algorithm and the basic principle of the Quaternion Fourier Transform algorithm. Finally, According to analysis and comparison, we summarize the advantages of the frequency domain method.
