Analysis of security enhancement in video coders

Abstract

Video compression is the process of encoding a video file in such a way that it consumes less space than the original file Large video files make a problem when recording long sequence of videos Video compression reduces the size of the video file by eliminating redundant data from the original video file Video compression is a vast process in which the raw files are converted into a tiny format Security with video file is an essential factor in multimedia applications that are becoming the key concern Also video encryption scheme plays a vital role to protect video contents from unauthorized access Video encryption scheme provides demonstrable security of video data from unauthorized users It is very much essential to provide efficient motion estimation system which determines the quality of compression Also an effective security mechanism which consumes less time for its operation is needed to protect the video content In this research different motion estimation systems with secure video encryption technique in H264 encoder are addressed to provide effective security during video compression newline
