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 understood. 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.

Highlights

For the protection of our private information the data security is most necessity
Cryptography is a technique in which secret data is change by its character in such a way that third any intruder can’t identify the message
Capacity means that how much system have capable of hiding the information into cover media, security means it should be secure the content of secret data from unauthorized user attacks, and robustness tends to system should be roust to any change in the content of secret message [3], [5]

Summary

Introduction

For the protection of our private information the data security is most necessity. a day use of internet increases so there are chance of secret data can be hacked by cyberpunk. Cryptography is a technique in which secret data is change by its character in such a way that third any intruder can’t identify the message. Capacity means that how much system have capable of hiding the information into cover media, security means it should be secure the content of secret data from unauthorized user attacks, and robustness tends to system should be roust to any change in the content of secret message [3], [5]. Discrete cosine transform and discrete wavelet transform This method is introduced in video steganography baced on the expanded markov and joint distribution on the transform domain – detecting MSU stego video [8]
