Image Steganography is superimposing a secret image into a cover image such a way that perceptability and properties of cover image remains unchanged. In this paper proposing a modified approach of Image Steganography which is based on Block DCT and Huffman Encoding without inserting a Huffman table into stego image. In the proposed method embedded an encoded secret image (Huffman Table) to the transformed cover image (Block DCT) by ± 1 embedding method. To working on N x N block DCT transforming cover image. The experimental result shows that the modified approach gives better Steganography properties of stego image in terms of PSNR, correlation coefficient than the existing algorithm.
