Steganography is an art of hiding the secret information inside digitally covered information. The hidden message can be text, image, speech or even video and accordingly the cover can be chosen from either an image or a video. The message is concealed in lowest bits of cover. We shall perform steganography on videos and hide message in encrypted form, by this security is increased by two times. The mostly used technique is LSB (Least Significant Bit)[1] steganography. But instead of simple LSB technique, we will use Lazy Lifting Wavelet transform [2] and then apply LSB in the sub-bands of the video that has been obtained. The proposed approach will utilize the video as well as audio component to hide message, in video component we will hide the encrypted message and in audio we hide the length, up to which the message is hide in video, using LSB technique. Experimental results show that the proposed technique has a high payload capacity and low computational requirement.
