A new digital image watermarking algorithm based on image interlacing, DWT, DCT

摘要

The availability of digital data such as images, audio and videos to the public is growing day by day with the expansion of the Internet. Hence preserving the rightfulness of the data is a critical factor and the solution is effectively provided by digital watermarking. Digital watermarking is a developing technology which ensures and facilitates security, authentication and copyright protection of digital data. We tries to propose a secure and robust watermarking algorithm based on the combination of image interlacing, DWT & DCT techniques. To minimize the bandwidth requirement during transmission of watermarked image EBCOT algorithm to compress the image and error correcting codes are applied to receive error free content at receiver end.
