Digital image watermarking (DIW) is the way which is resilient to many attacks on digital mediabased on image where data authentication is full by embedding a watermark in image characteristics.This work incorporates a novel method for DIW using three level discrete wavelet transform (3DWT)-Singular value decomposition (SVD) and PNN classifier with various attacks.Extensive experiments present that proposed watermarking algorithms have high robustness and a good imperceptibility to numerous usual image processing attacks, such as Gaussian blurring, noise attack, Swirl Attack and Negative Attack.To estimate the algorithm efficacy and extracted quality of image watermarking, we used extensively known measurements of image quality function, for example SNR and L2 normalization (L2Norm).Results indicate the excellent invisibility of the extracted watermark image (SNR = 45.68dB), as well as exceptional watermark extraction (L2Norm = 3.0329).
