Secure and effectual data transmission in video steganographic system using frame selection techniques

Abstract

newlineNowadays internet application requires for secure and effective data transmission Cryptography Steganography and Watermarking is the major solution for providing security in internet applications Steganography and Watermarking is used for hiding secret data in multimedia files Secret text data can be embedded into an image audio or video files The proposed research work uses video file as cover media and secret data or hiding data as text Because video files can be used for hiding more amount of secret data By using Watermarking technique the hidden data can be identified by third person but it can t be modified By using Steganography technique the hidden data cannot be identified by third person Cryptography technique is encrypting the secret data for improving security This proposed research work proposes video steganography for secure and effectual data transmission with the help of different frame selection techniques Hence secret text data are embedded in the video file by using motion vector analysis It means a new steganography algorithm is proposed which forms motion vectors based on object motion in a video stream, and then the secret information is embedded in motion vectors of moving objects Actually magnitude is calculated for motion vectors then the secret text data is embedded in the magnitude of the motion vectors This methodology increases the PSNR value minimize the mean square error and computational complexity In the proposed research work the sender sends a message within the style of video victimization using MP4/AVI files to the receiver Hence secret text message is encrypted by triple DES algorithm and embedded in different frames of the video
