Abstract

This study combines the Redundant Discrete Wavelet Transform (RDWT) and Singular Value Decomposition (SVD) methods as a watermarking technique used to increase the imperceptibility and robustness of digital images. The purpose of this study is to measure or load the Peak Signal to Noise Ratio (PSNR) and Correlation Coefficient (CC) values for the inserted image file. The digital image used consists of 11 cover images and 1 watermark image in JPEG format. Testing is divided into three processes, namely the insertion process, the extraction process, and the extraction process after an attack. Tests carried out in the insertion process produce the highest value on the parameter scaling parameter 0.01 with a value of 44.74 while the test carried out on the extraction process produces the highest value on the parameter scaling factor 0.1 with a value of 34.26. The test results prove the value of PSNR and CC has high resistance to the type of attack and has a low defense to the type of speckle attack
