摘要：A new image steganography method for hiding data using Gray Level Images in Spatial Domain is proposed in this paper. This method uses the 5th, 6th and 7th bits of pixel value for insertion and retrieval of message by using the same bits of pixel value. This method is an improvement over earlier methods like least significant bit (LSB) method [4] and gray level modification (GLM) method [6]. This method retains the advantages of above said methods but discards the disadvantages associated with above methods and provides us the better results.
