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. In this research apply Multi-Level Steganography for image steganography was presented. MLS consists of at least two stenographic methods utilized respectively. Two-levels of stenography have been applied; the first level is called (the upper-level), and it has been applied using enhance LSB (secure LSB-L1) image steganography, the secret data in this level is English text, and the cover is Bitmap image, the output is a stego_image called (intermediate image). The second level is called (the lower-level); it has been applied using another enhance LSB (secure LSB-L2) based image steganography. In this level another Bitmap (BMP) image has been used as a cover image and embeds (the BMP image output from level one) as a secure data and generates the new BMP image as stego_image. Lossless data compression technique using Huffman, LZW algorithm and Winrar Application between First and Second level of steganography are applied.
