Abstract	:	The rapid growth of the ~ntemet and digital multimedia makes communicationeasier and more extensive than before. People can make and share products quickly andelectronically. This presents o strong demand for the protection of copyright andintellectual property for audio, video, image, and document. Image watermarking is atechnique that plays a very important role in protecting the copyright of image data.In this research, a digital image watermarking technique based on the redundantdiscrete wavelet transform (RDWT) method in the transform domain is investigated. Theperformance and robustness of this technique is tested through common image processingoperations, such as filtering, requantization, halttoning, and common still imagecompression techniques such as PEG, etc.,....-...,..tested for theQ1 PC1 bus cardBoth these projects mere sofixare des elopment efforts tonards contributing to dlfferentaspects of Roboucs and lZ1echatronics projects m the Controls and Roboucs Group..
