This document summarizes a research paper that proposes a new method for encrypting images with high security when transmitting over a network. The method involves dividing the source image into multiple parts, encrypting each part separately with a different encryption key, and then combining the encrypted parts into a single encrypted image for transmission. This provides stronger security than encrypting the whole image with a single key. The document provides background on existing image encryption techniques and visual cryptography. It then outlines the proposed new methodology, which first divides the source image into multiple smaller images, encrypts each part separately with a different algorithm/key, and has two options for transmission - sending all the encrypted parts individually or combining them into one encrypted image.

ABSTRACT
The security of and information is being used from an ancient age. In an ancient age the
information was also hiding using different methods called steganography. It is the process of
securing information behind any one or many of the other images. Now a day’s steganography is
also using for image security, but most widely used method is encryption and decryption. Image
Encryption is a process of hiding image from unauthorized access with the help of secret key that
key can be private or public .It is used in many areas where the security risk is very high.
The encryption and decryption mechanisms will improve the security. Information security is
a very important issue in this world, when the information is transfer from one geographically
location to another geographically location through network there is chance of steal of information
through network.
Generally information is encrypted and decryption using one encryption key and one
decryption key for information such as image. In our proposed work an image is encrypted in various
parts using different keys, for each part of the image. Now a day’s parameters (like Bandwidth,
Storage, and time etc.) are not the problem when security is matter.
Keywords: Image Encryption with High Security.
1. INTRODUCTION
As the world changes rapidly technology is also changing rapidly. In advancement of
network technology, large amount of multimedia information is transmitted over the Internet
conveniently. Various confidential data such as Banking and other secured data, space images taken
using satellite and commercial identifications are transmitted over the Internet. While using secret
information we need more secure information hiding techniques.

In our proposed method we are securing information sixteen times instead of one in a single
information transmission.

RELATED WORKS
The concept of the mosaic images was created perfectly and it has been widely used. Four
types of mosaic images namely crystallization mosaic, ancient mosaic, photo mosaic and puzzle
image mosaic are proposed in [2]. In the first two types, the source image is split into tile image and
then it is reconstructed by painting the tiles and they are named as tile images. The next two types
include obtaining target image and with the help of database, cover image has been obtained. They
may be called as multi-picture mosaics. The previously mentioned mosaic image namely
crystallization mosaic uses voronoi diagram which was proposed in [3]. The main concept of voronoi
diagram includes by using different sites. The blocks are placed in the sites randomly. Based on the
original image, the blocks are being filled by the colors.
The emerging Visual Cryptography (VC) techniques used in the secure transfer of the
thousands of images collected by the satellite which are stored in image library and sent to Google
for use on Google Earth and Google maps. The related work is based on the recovering of secret
image using a binary logo which is used to represent the ownership of the host image which
generates shadows by visual cryptography algorithms [4]. An error correction coding scheme is also
need to create the appropriate shadow. The logo extracted from the half-toned host image identifies
the cheating types. Furthermore, the logo recovers the reconstructed image when shadow is being
cheated using an image self verification scheme based on the Rehash technique which rehash the
halftone logo for effective self verification of the reconstructed secret image without the need for the
trusted third party (TTP).
One of the best known techniques to protect data such as image is Visual cryptography [4].
The visual cryptography scheme as a simple and secure way to allow the secret sharing of images
without any cryptographic computations [5] VCS is a cryptographic technique that allows for the
encryption of visual information such that decryption can be performed using the human visual
system. The basic scheme is referred to as the -out-of- VCS which is denoted as VCS. Given an
original binary image, it is encrypted in images, such that where a Boolean operation is an image
which appears as white noise, and is the number of noisy images [6]. It is difficult to decipher the
secret image using individual’s. The encryption is undertaken in such a way that one or more out of
the generated images are necessary for reconstructing the original image. In the case of (2, 2) VCS,
each pixel in the original image is encrypted into two sub pixels called shares. The concept of visual
cryptography using visual information pixel (VIP) in [4] synchronization and in diffusion error to
attain a cryptography encryption method for color visual, that produces meaningful color shares with
high quality visualization in [7] and [9]. Synchronization in VIP retains the pixels positions that
carrying visual information of original images throughout the color channels and diffusion error
generates shares pleasant to human eyes. In [4] color VC encryption method which leads to
meaningful shares and is free of the previously mentioned limitations.
The method (idea) is simple and efficient. It relies on two fundamental principles (rules) used
in the generation of shares, namely, diffusion error and Synchronization in VIP. Diffusion error is a
simple but efficient algorithm for image halftone generation. The error in quantization at each pixel
is filtered and (regenerate for next) fed to future inputs.
3. PROPOSED RESEARCH METHODOLOGY
In our proposed work we will read a image (A) by using some command OR algorithm we
will divide the image in to I*I parts i.e. (2*2, 4*4) parts. Each part of the image will be treated as a

single image we can say that IMG1, IMG2, IMG3 … IMGn. The output of the above i.e. IMG1,
IMG2, IMG3 ……. IMGn, and each parts of the image is treated as a single image. And using
different encryption algorithm, we will encrypt each images, we can say that encrypted images
(Encrypted images= EIMG1, EIMG2, EIMG3 …EIMGn). After that we have two options
1) We can transfer all sub encrypted images EIMG1, EIMG2, EIMG3 … EIMGn at receiver
side.
OR
2) We can combines (Merges) each all encrypted images EIMG1, EIMG2, EIMG3 … EIMGn.
And make a single encrypted image A1, for transfer.
