SECURED DATA HIDING BY USING EXTENDED VISUAL CRYPTOGRAPHY

Megha Goel, M. Chaudhari

Abstract: Due to the rapid advancement of the internet large amount of data is transmitted over the internet. Some of the transmitted information is very important like password, confidential file, security codes etc. so it is very important to provide security to these data. In computer technology there are two ways to provide security to the data they are cryptography & steganography. Although, in the past, there has been various research related to cryptography & steganography but neither of them provide enough & strong security. So this paper proposes a novel approach for data hiding by combining steganography & extended visual cryptography. Visual cryptography was invented by Moni Naor & Adi Shamir in 1994. Visual cryptography hide secret image within one or more images & then generate shares. For share generation this paper uses Visual Information Pixel (VIP) & error diffusion technique.
