LSB Steganography in Color and Grayscale Images without using the Transformation
Abstract:
A technique which enables to have a secret communication in modern technology using public channel is known as steganography This paper deals with constructing and implementing new algorithm based on hiding a large amount of payloads (image, audio, text) file into color image. We have been used adaptive image filtering and adaptive image segmentation with bits replacement on the appropriate pixels.The information has to be hidden in the LSB of the cover image,so there is no much chances present in the embedded image.High security layers have been proposed through three layers to make it difficult to break through the encryption of the input data and confuse steganalysis too. We show that our algorithm can embed efficiently a large amount of data that has been reached to 90% of the image size with high quality of the output. . It is observed that the proposed algorithm has excellent PSNR, provides high level security and more robust compared to individual transform techniques.
