Steganography using B+trees and LSB
Tanushree Shelare, Varsha Powar · 2016
Data is the most valuable thing today from an individual to an organization because of it large size and useful information. But it is vulnerable and is more prone to attacks. Steganography hides selected files securely in a file system in such a way that without the corresponding access keys, an attacker would not be able to find their existence. Many steganography systems assure reliable data security over the internet. Still there are vulnerabilities which cause threat from attacker. B+trees are fast indexing method and increase performance. The aim of this paper is to introduce an efficient and strong approach for hiding secret message within image by using B+tree as a tool to compress the secret message, and an efficient steganographic algorithm for hiding text files in images for security. We have compared the proposed system with other existing Steganographic techniques. Our main focus is to maintain the quality of the image without distortion. However we have also tried to increase the embedding capacity of the hidden message in an image.
