A Non-Blind Robust and Impercept Watermarking Using Discrete Cosine Transform and Discrete Wavelet Transform

Non-blind watermarking is a form of with watermark image validation process that requires host image. The use the transform domain more robust and imperceptible. method resistant to various forms digital attacks. In this study, Discrete Cosine Transform (DCT) Wavelet (DWT) were selected as insertion algorithms. DCT faster attacks, especially in compression but has lower imperceptibility than DWT. DWT also known be noise filtering, blurring, cropping, high depending on sub-band selection not Based each algorithm's advantages disadvantages, there an opportunity combine it analyze compare results itself. To test imperceptibility, we used Peak Signal Noise Ratio (PSNR), while robustness, Cross-Correlation (CC) Bit Error (BER). Without PSNR proposed can reach 71 dB. CC value without attack perfect 1 BER = 0. highest result filtering attack. From tests have conducted, been proven DCT-DWT imperceptive previous studies
