The important issue of modern communication is establishing secret communication while using public channel and is achieved by steganography. In this paper, we propose Coherent Steganographic Technique using Segmentation and Discrete Cosine Transform (CSSDCT). The cover image is divided into 8*8 blocks and DCT is applied on each block. The number of payload MSB bits is embedded into DCT coefficients...
In recent years Steganography plays an important role in secure communication. Steganography is a technique of embedding secret information into cover media, like image, video, audio and text, so that only the sender and the authorized recipient can detect the presence of secret information. In this paper we propose Spatial Domain Steganography using 1-Bit Most Significant Bit (MSB) with chaotic manner...
