The aim of this research is to design a steganography algorithm which not only hide the message behind the image but also provide more security than others. For the purpose of security, encryption technique is used with a user-defined key. In the algorithm designed by author a message is hide into an image in the form of an image that is using image generation method message is converted into the image of predefined format and then by using designed algorithm that image will hide into the cover image. RGB image format is used to improve the quality of the stego image. At last that RGB image will saved as BMP image file so that no lossy compression can occur and the original message do not destroy and can be extract as it is.
