Now-a-days, several well-organized data hiding methods have been introduced and implemented using video steganography channel. Data hiding is to accomplish better data communication by hiding information into a video medium carrier to form an unrecognizable code stream. In the consideration of security aspect for communication process especially in video we enhanced this QoS factor security in this paper. Due to heavy packet loss, channel bit errors, video stego analysis have become a significant addition to the security aspects and are extensively developed as a complementary line to conventional security method. In this work, Fourier Transform With Security (FTWS) technique is applied for improve the security on video files in communication process. In this paper, a Secure Hash Polynomial Function to provide multi-layer security according to the modular additions and density functions is presented. Through the analysis of performance factor the security is important factor in our research. Finally, the simulation results evaluated by Video Quality Experts Group with parameter such as security with multilayered for 110 frames using MATLAB. It shows that the method FTWS enhance the security significantly compared with typical state-of-the-art methods.
