Our modern civilization is based on Internet and sometimes it is required to keep the communication secret. It becomes possible by using two techniques: Cryptography and Steganography. The key concept behind both of two approaches is to hide information in anyway. There is little difference of these two approaches. Cryptography conceals the content of the secret message whereas Steganography is more advanced concept of the former. It embeds the secret message within a cover medium. Steganography is art and science in which the secret message is embedded into a cover medium so that no one else than the sender and the recipient can suspect it. So the third parties except the sender and receiver are imperceptible and unaware of the existence of the secret message. There are so many efficient Steganographic techniques like that text, image, audio, video and so on. This paper proposes only Image Steganographic method using Block Level Entropy Thresholding Technique.
