Comparative Analysis of Image Security Using DCT, LSB and XOR Techniques

In current technology, the majority of data is transferred over the internet, and the most useful data type is image. As a result, image security is necessary for safe transmission. Image security methods are used to safeguard the image. Low MSE and high PSNR values are necessary for improved hiding. This paper shows the comparative analysis of DCT, LSB and XOR image security techniques and obtained the MSE and PSNR values from these techniques and shown techniques, which provided the better image security.
