摘要：Editing, reproduction and distribution of the digital multimedia are becoming extremely easier and fasterwith the existence of the internet and the availability of pervasive and powerful multimedia tools. Digitalwatermarking has emerged as a possible method to tackle these issues. This paper proposes a schemeusing which more data can be inserted into an image in different domains using different techniques. Thisincreases the embedding capacity. Using the proposed scheme 24 binary images can be embedded in theDCT domain and 12 binary images can be embedded in the spatial domain using LSB substitutiontechnique in a single RGB image. The proposed scheme also provides an extra level of security to thewatermark image by scrambling the image before embedding it into the host image. Experimental resultsshow that the proposed watermarking method results in almost invisible difference between thewatermarked image and the original image and is also robust against various image processing attacks.
