Watermarking Using Energy-LSB Embedded Method

Digital watermarking technology is increasingly used to protect copyright and demonstrate ownership of digital multimedia (such as text, music, photos, videos). In order safeguard intellectual property rights rules for multimedia, this project suggests a text watermark algorithm. The process hiding little or grayscale images the main focus, though. masking in high-color high-density area block picture has been proposed using an embedding technique based on energy function Least Significant Bits (LSB) method. Even with various format types sizes chosen conceal cover changing message size, quality results that image suffers from less distortion than image, suggested algorithm powerful random even smaller sizes. An additional optional choice encrypt before also recommended because doing so would make it harder hackers read text. This can be encrypted Caesar cipher method implemented images.The experimental extracting large number were satisfactory, giving level peak signal-to-noise ratio (PSNR) Signal Noise Ratio (SNR) low mean square error (MSE) values. However, PSNR degrades more quickly LBS size increases, was determined suitable applying rather stego It employed share information securely
