Today, due to rapid use of digital applications and services, the data lose is very usual. To protect the digital data a way, we proposed a new robust digital watermarking technique using Haar Transform and Orthogonal Transform where a transparent watermarking or visible watermarking is used. By using this technique, we can get digital data without degradation in quality. Digital watermarking technique is a technology to embed the additional or authorized information into a host signal to ensure the security and protection of the digital information. The watermarking scheme deals with the two procedures: Embedding the watermark and Extracting the watermark. There are two approaches used to follow the procedures: Digital Wavelet Transform (DWT) and Principle Component Analysis (PCA).
