Abstract

The need to develop new encryption schemes comes from the fact that traditional encryption schemes for messages are not suitable for multimedia data stream. Valuable multimedia content such as digital images, however, is vulnerable to unauthorized access while in storage and during transmission over a network. A new steganography algorithm is presented for hiding a secret image in a cover image. A fundamental task in many image processing applications is the visual evaluation of a distorted image. The scheme image Cryptography is used to encrypt an image or document by breaking into shares. In order to take the advantage of this property, the third party can recover the secret image if the shares of secret image are passing in sequence over a network. This paper presents an approach to encrypt image using Cryptography (2, 2) scheme for easy transmission over network. The aim of this paper is not only to show the efficiency in hiding the attributes with better cover image selection using steganography technique but also presents better image encryption with visual cryptography scheme for secured and effective image transmission over internet.
