- W3202118848 abstract "With the widespread usage of the Internet, security takes precedence above anything else when transmitting data. This research proposed a hybrid encoding approach with watermark embedding that provides excellent security. Our novel strategy is based on cryptography, which allows it to recognize higher secrecy and efficiency. In this research, a hybrid method is used to support visual watermarking and cryptography to embed vital data. Our effort aims to improve the security of hidden facts embedded in the cover picture. The embedding and encryption of the watermark image into the cover image document were performed in two steps. To begin, two keys and an XOR bit operation were used to generate a large number of distinct keys for encryption. Second, a modified approach of the least significant bit (LSB) technique was adopted to hide a high-resolution watermark picture in the cover picture. The suggested second stage involved encrypting the cover image using the asymmetric key cryptography method (RSA), which provides additional secrecy during picture transmission. The original picture, the watermark photo, can be recovered and decoded using the permitted techniques. As a result, encoding and watermarking may be combined, giving the term joint encoding and watermarking legitimacy. Peak Signal to Noise Ratio (PSNR) and relationship aspects are greater with this method. For the implementation of hiding and encoding for the watermark and encoding the digital cover picture, MATLAB-GUI software was utilized. Experimental results demonstrated a good performance with a good correlation for all encrypted images and very high PSNR of the Stego images." @default.
