摘要：Steganography is the art and science of writing hidden messages in such a way that no one, apart from the sender and intended recipient, suspects the existence of the message, a form of security through obscurity. Steganography is a Greek origin word which means "hidden writing". Steganography word is classified into two parts: steganos which means "secret or covered" (where you want to hide the secret messages) and the graphic which means "writing" (text). It can be defined as the art of hiding the fact that communication is taking place, by hiding information in other information. Many different carrier file formats can be used, but digital images are the most popular. In this paper, a new image steganography method is proposed. The proposed method hides the secret message inside the cover image by representing the secret message characters using Braille method of reading and writing for blind people that can save more than one-fourth of the required space for embedding. From the experimental results it is seen that the proposed method achieves higher visual quality as indicated by the high peak signal-to-noise ratio (PSNR) in spite of hiding a large number of secret bits in the image.
