Combination of cryptography and Steganography for secure communication is an application, which combines both Cryptography methods (i.e. encryption and decryption) and Steganography techniques to make the communication more secure. The outcome of this project is to create a cross-platform tool that can effectively hide a message (i.e. Word document) inside a image file. It is concerned with embedding information in a secure and robust manner. In embedding stage, the color of the cover image is separated to its component (RGB) then all are partitioned into non-overlapped blocks using quad-tree partition that is called range, and down sampling the range images to quarter its size to generate the domain. The domain pool is partitioned in to over-lapped blocks.
