Multimedia Data Hiding: Three-in-One

Data hiding considers a class of process utilized to embed data into various formsof media, such as image, audio, or text. The suggested data (text, audio, binaryimage) in image steganography system is a new technique used to embed data intocolor image. Instead of using the least-significant-bit-plane (LSB 1) of the cover forembedding the data, third-least-significant-bit-plane (LSB 3) has been utilized inorder to increase the robustness. First and second-least-significant-bit-plane (LSB 1and LSB 2) can be changed according to bits of the data, to reduce the differencebetween the cover and the stego-cover. Then, for more protection to the datacharacters, a stego-key has been constructed to permute the data characters beforeembedding it. Experimental results of the modified technique proves that Peak-Signal-to-Noise-Ratio (PSNR) is greater than the traditional approach of LSBssubstitution. Thus, the proposed system introduces good results and it is suitable forseveral cases of life.
