ROBUST AND SECURE PIXEL DOMAIN DIGITAL IMAGE STEGANOGRAPHY

Steganography is used in various information hiding applications which encodes the secret data by hiding the existence of the information so that a viewer cannot identify the presence of the secret message. A data securing technique is proposed for embedding the information bits in color images (RGB planes). The input cover image is divided into separate R, G and B planes and then the secret data is embedded. For embedding and extraction, sequential and pseudo random encoding and decoding technique is employed. The randomization process during the encoding adds more security to the method. Experimental results are performed using USC-SIPI image database. Various performance evaluation parameters like PSNR, RMSE and SNR are computed in order to prove the better performance of the presented algorithm. Experimental results demonstrate that the proposed algorithm outperforms all the existing data embedding algorithms in terms of PSNR values
