A DWT-DCT combined approach for video steganography

Advancement in the use of internet network and growth of technology has led to increasing in Steganography. Steganography is the way of carrying out secure communication without giving any evidence for the attacker. Secret data is hidden inside other multimedia such technique of hiding data is called as Steganography. Video Steganography consider being the more powerful type of Steganography since data hiding capacity is more and processing a Video is very complex. This paper presents a novel approach of hiding text data within a Video. Video Steganography is carried by using frequency domain coefficient of frames. Our approach combines a DCT and DWT technique of hiding information together to get more PSNR and high capacity of hiding ratio.
