Steganography (from Greek steganos, or "covered," and graphie, or "writing") is the hiding of a secret message within an ordinary message and the extraction of it at its destination. The new steganography algorithm which is constructed and implemented hides a large amount of data (image, audio, text) file into color BMP image. Adaptive image segmentation with bits replacement on the appropriate pixels has been used. These pixels are selected randomly rather than sequentially by using new concept defined by main cases with their sub cases for each byte in one pixel. Some specific image based steganography techniques show that an observer can indeed distinguish between images carrying a hidden message and images which do not carry a message. In this algorithm, 16 main cases with their sub cases cover all aspects of the input data into color bitmap image. High security layers have been proposed through three layers to make it difficult to break through the encryption of the input data. Comparison is made with the previous steganography algorithms like S-Tools and factors like the amount of data that could be hidden, the nature of the image and the length of the password have also been discussed. The proposed algorithm can embed efficiently a large amount of data with high quality of the output.Keywords
