In recent years, security is a complicated task in the transmission medium due to the rapid development of multimedia contents such as image, video, audio over the network. Nowadays many security aspects are available to protect the information from the people who have malicious intentions. Cryptography, Steganography and Digital watermarking are most commonly used techniques for protecting the secret and sensitive information. This paper presents a new hybrid scheme for protecting the text message during transmission over the network. In this hybrid scheme, a combination of three symmetric key encryption algorithms are used for the encryption process and video steganography is used for hiding process. The proposed hybrid scheme is evaluated based on the payload capacity and CER value for the quality of stego-video that provides authentication and validation.
