Robust Medical Image Watermarking Scheme with a Novel Modified Embedding Algorithm in comparison to a Lightweight Encryption Algorithm

The primary goal is to evaluate two separate methods, namely a new enhanced embedding algorithm (EmA) and a lightweight encryption algorithm (LEA), with the aim of improving the peak signal-to-noise ratio (PSNR) of a robust medical picture watermarking (WM) methodology. This study contrasted two groups: one using the lightweight encryption technique (N = 10) and the other using the innovative modified EmA (N = 10). With an alpha of 0.05, an enrollment ratio of 1, a 95% confidence interval, as well as power of 80%, the power programme determined a total sample size of 20. A PSNR of 55.4650 dB was reached by the innovative modified embedding technique through analysis of the simulation data, whereas a ratio of 42.2360 dB was acquired by the LEA, with a significance level of 0.000 (p<0.05). In comparison to the Extracting algorithm technique, the new updated EmA approach performs much better.
