Certain investigations on performance analysis of color image and video steganography using new encoders and decoders

Abstract

Computers and related Internet of things have become essential in normal life which simultaneously increase the security issues While transmitting the information in digital media digital watermarking steganography and cryptography are some important techniques used to improve the efficiency of secret communication Steganography is the art and science which attempts to hide the information in secure communication through the cover media The cover media types may be a digital image text document different digital audio formats and any video streams The objective of this research is to investigate and improve the performance of various steganographic systems such as image steganography audio steganography and video steganography In the first proposed work Robust Multitier Spatial Domain Secured Color Image Steganography in Server Environment MSS SE method intends to bring down the probability of disclose the steganographic image identification in secure communication networks In MSS SE steganography algorithms instead of transmitting directly the actual image which is available in the server a cover image and confused image selected randomly from the same sever have been transmitted The MSS SE system has been formulated with Pseudo Noise code and the distance matrix algorithm which results increase in the robustness and the security The system also provides less time complexity of On In the second proposed work Sparse Data encoder and decoder to improve newline
