- W2977497964 abstract "Presently, multi-day data security is the greatest issue of challenging over the world. There are various systems accessible for image and data security; watermarking is one of them. This paper proposes a new technique for watermarking encryption image by using LSB and based on the frequency and geometric transform. In this work, the Discrete Wavelet Transform (DWT) technique is used to deal with the cover image at the frequency domain without spatial domain where late studies have shown the strength of this type of transform. The rotation geometric transforms applying on the logo image to preserve it and to protect it from eavesdropping and unauthorized entities. The rotate transform considers the type of disguise. Therefore, to increase the security of the watermarking system, it should be considered to also apply Rivest Cipher 4 (RC4) encryption algorithms on logo image before perform watermarking embedding. In finally Least Significant Bit (LSB) is used to embed a logo image in the cover image. The demonstrated experiment is based on Peak Signal to Noise Ratio (PSNR) and Mean Squared Error (MSE), the DWT achieves better results as compared to other methods when the rate of PSNR reached from 50 dB to 60 dB." @default.
