Abstract

Now the world became more digitalized and the digital communication over the internet increases day by day. At present days the digital data is widely transfer over the internet and the whole information of living being has been uploaded on the server. With the increase of internet use, the misuse of private data also increases. There exist are many hackers and they may easily hack our private data too. So now a days security of private data has become major part of concern. For the prospective of security, cryptography and steganography of secret data can be used. In cryptography the original secret message is converted into ciphertext that is ununderstood. While in steganography technique the secret data is hiding in cover media. Cover media may be multimedia file such as data, images, audios and videos. In this paper we are introducing video steganography technique using discrete wavelet packet transform (DWPT). Additional security can be achieved by using combined cryptography and steganography for better security of secret information. Result shows that the video steganography using discrete wavelet transform provide better performance parameter as compare to other technique of steganography.
