Secure Data Carrying Methodology Through Digital Protection Wall Using Higher LSB Technique over Wireless Network
Devika Gawande, Sharad W. Mohod · 2019
The secrecy and security of information has always been important to the people whenever it come to confidential data. Today there is advancement in internet technology and hence there has been increase in use of text and multimedia data transfer over internet. Thus this motivates us to add another layer of security to secrete data,which hides the confidential information within carrier. The carrier we used is the transfer of images that can hide secret information within the region of image. The paper proposes half toning visual cryptography technique with digital protection wall. Technique improves the imperceptibility as well as capacity of carrier by considering higher LSB layer for hiding secret information and replacing RGB component bit with secret information. Thus transfer of carrier through wireless media and recovering the secret data at receiving side. The data is extracted simply by using reverse algorithm. And the capacity, imperceptibility is compared by using various factors like cross correlation, MS error, peak to signal noise ratio. The executed protection wall is flexible so that carrier can hide the data within the protected area and shall protect from unauthorized user which will be known to receiver only.
