Steganography can be applied to different objects like text, picture, image and audio or video. This objects called cover object or carrier object of the steganographic method. Steganography is a very well-known method of information security through information hiding. Here two different steganographic methods have been used instead of using one steganographic method. This has been done with a layering approach. This method is named as multi-level steganography. Multi-level steganography has advantage of difficult decoding and sending two secret message through a single cover object.
