Steganography, technology of information hiding that allows people to communicate secretly, in which actual data will be kept hidden inside the cover object. This paper deals with multimedia hiding system in which secret multimedia file is kept hidden in dual cover images. The proposed model takes the secret multimedia file and divided it among two cover images of same dimensions and size. The multimedia files are considered as a continuous byte and then it is vertically split into two halves, in which one half is the most significant half bytes, and the other half is the least significant half bytes. Then the two halves are embedded inside the two cover images using a four bit least significant replacement technique. To avoid capture of stego images by an attacker, it is expected to sent stego images separately through different channels. The secret multimedia file can be extracted by combining least significant half bytes of two stego images. The recovered secret multimedia file is similar in structure and content with original hidden multimedia file.
