Secure Data Transmission of Video Steganography by Hashing Pixel Values with DWT

Hnin Lai Nyo | Aye Wai Oo

Abstract: The growing possibilities of modern communications need the high security especially on computer network. Due to the increasing number of data being exchanged on the internet, it is becoming more important to the network security. Therefore, the confidentiality and data integrity are required in order to protect against unauthorized access and use. This has caused to the emergency growth of information hiding research area. In this system, combination of steganography and cryptography techniques are used to transmit data securely to the authorized person and to improve imperceptibility and payload capacity. The hashed frequency values of secret image are embedded in the video file with the use of Discrete Wavelet Transformation and Least Significant bit. The secret key generated these hashed values is encrypted with the another secret key by using a new encryption algorithm, Twisted Exchange Algorithm and the resulted encrypted key is hide behind the audio file with the parity bit technique. The system performance is measured MSU video quality measurement tool and the results are analysed with different parameters.
