Abstract: The internet provides a method of communication to distribute information to the masses with the growth of data communication over computer network, the security of information has become a major issue. Cryptography and Steganography are the two popular methods for secure data. Cryptography is the science of change the format of text from readable to unreadable text. Steganography is technique and art of hiding a secret message in carrier file. Steganography is the technique and art of hiding a secret message in a carrier file. A method proposed in this paper to improve the security system is to combine encryption and concealment. In this research the proposed to improve security system by combination between cryptography and steganography. Firstly, the International Data Encryption algorithm (IDEA) is used to encrypt the secret message. Secondly, the encrypted message has been embedded and distributed in even-frame in the video file using LSB steganographic and then applying DCT steganographic also to this stego-video. Thus, two levels of security have been provided using the proposed hybrid technique. In addition, the proposed technique provides high embedding capacity and confidentiality.
