Abstract - Cryptographic system develop for the secure our data.
There are number of cryptographic protocol and they provide
security. In this paper used random password. Plaintext
converted into the cipher text using random password scheme in
unbreakable cryptosystem. After used steganography to hide a
secret message. Embedding a secret message into the cover
image is called stego image. A large number of steganography
program use the least significant bit (LSB) embedding as the
method of choice for hiding data. After used another protection
lock for secret message that is cross over algorithm. Cross over
algorithm used to modify the pixel location of stego image. In
cross over algorithm first shuffling column pixel and after
shuffling row pixel. This proposed system is highly secure &
reliable. This data secure implementation is done in java
platform.
Keywords - Steganography, Unbreakable Cryptography, Crossover Algorithm, Crypto-analysis, modified pixel image, Stego
image.

INTRODUCTION
A. Cryptography
Cryptography referred as the encryption and decryption.
Encryption is the process to convert plaintext into the cipher
text, while in Decryption process, the cipher text convert into
plaintext. In cryptosystem used the ordered list of element of
finite possible plaintext, cipher text, key and the encryption
and decryption algorithms which correspond to each key. So
It used unique password to provide secure cryptosystem .That
is developed by Gibert Vernam in 1918.It used the secret key
(PAD) as the same length as the plaintext. This secret key is
not reusable .Crypto analysis is the term used for the study of
method for obtaining the meaning of encrypted message
without secret key normally required to do so that is the study
how to crack encryption and decryption process or their
implementation details.
B. Steganography
The term steganography is comes from the Greek words
stegos which means cover and grafia means writing defining
it as covered writing. In image steganography the secret
message is hidden in images. Steganography is the technique
for secret communication .It is the practice of encoding
/embedding secret information in a manner such that the
existence of the information is invisible. The Original files
can be referred to as cover image. After inserting the secret
message it is referred to as stego-image. A key is used for
hiding/encoding process to restrict Detection and extraction
of the embedded
Image Steganography is the art and process of secret
communication. Steganography program used for hiding data
it has low computation complexity and high data encoding
capacity. The Steganography system deals with secret
message encoded in least significant bits of the cover image
that is called stego image, and this security given by the
secret key. Secret message embedded so, stego image does
contain any detectable artifacts. Digital image files that
contain the information can be used as cover image to
embedd secret message. The best embedding method of
steganography to hide a message is lsb based steganography:
in which right most bit in a binary form is replaced with a bit
from the embedded message
In this paper one more protection lock for the secret
message that is called cross-over algorithm This cross-over
algorithm is used to modify the image pixel position of stego
image, in this algorithm shuffling pixel row and column. So,
detection of secret message is complex. Both the topic of
steganography and unbreakable cryptography used for image
security research on combining these two topic but results are
not good with respect to RS analysis. The use of
steganography
in
combination
with
unbreakable
cryptography is the study of model and a lot of challenges to
detecting such hidden messages and encrypted data
.

Image Security Using Steganography and Cryptographic
Techniques for securing the image by encryption is done by
DES algorithm using the key image. The decryption can be
done by the same key image using DES algorithm.
IV. PROPOSED SYSTEM
C. Literature Survey
The word cryptography derived from Greek word “Kryptos”
means “Hidden secret” and “graphein” means writing”.
Cryptography mostly referred the encryption, which is
process to converting the information into the unreadable
format. Decryption is reverse of that. Cryptography demand
increases in industry interest and individual interest that is
secure wireless communication. In ATM card, computer
password also used the cryptography.
The word steganography derived from Greek word,
“Steganos” meaning “cover” and “graphic “meaning
“writing”. The first published work describing steganography
was written by the German abbot, Johannes trithemiu (14621516). Steganography it means the art of hiding Data.
Different method were used during the worlds wars just like
using invisible ink for message and placing small dots above
or below letters in a text. The cover text is often chosen to
imitate spam-message due to the vast spread of such message
in steganography.
II. MOTIVATION
The first reason for selecting steganography among the list of
possible project topics was due to an unfamiliarity of the
word that twigged an interest in the given subject.
Second reason for researching the topic was after reading an
online article in the USA titled 'Terror groups hide behind
Web encryption' which claims terrorists particularly, Osama
bin Laden and the al-Qaida network, they are using
steganography for secret communication with each other in
planning terrorist attacks. It uses the images with hidden
messages are placed on bulletin boards for other terrorists to
pick up and retrieve hidden messages. So the current thinking
has yet to be proven.
III. RELATED WORK
Combine use of Steganography and Visual Cryptography for
Secured Data hiding in Computer Forensics(2012) designed a
feasible RS-resistance secure algorithm which combines the
use of both Steganography and Visual Cryptography. Many
RS analysis has a potential to detect the hidden message by
the statistic analysis of the pixel value.
The proposed system is basically a framework designed in
java swing with the Embedding and Extracting process of
steganography, cross over algorithm and cryptography.

Fig 1. Proposed System
Highly secure steganography for the security of secret
message in an image. User (user 1) should be able to secure
the data using steganography which is used for secrete
communication. Users should be able to encrypt or decrypt
the secret message. In encryption process user gives secret
message as an input of Cryptography module (Module 1).
The cryptography modules generate a cipher text and secret
key for user which is use after for decryption process.
Cryptography module provide cipher text and User provide
cover image as an inputs of steganography module (module
2) respectively, steganography module generate stego image
the secrete message embed into the cover image is called the
stego-Image. In LSB based steganography the data are embed
into pixel. Each pixel represent 8-bit binary value and the
data is embed by replacing digit of lsb position of pixel value.
The selection of pixel is random manner for better security it
is an encoding method of steganography where the right most
bit in a binary number stream is replaced with a bit from the
embedded message. LSB steganography has low
computational complexity and high encoding capacity.
Digital images and other computer files which contain
perceptually irrelevant or redundant information can be used
as “covers” or carriers to hide secret messages. The generated
stego image is converted into modified pixel image by
shuffling row and column pixels of stego image in Cross-over
algorithm (module 3). Cross over algorithm first shuffling the
column pixel then shuffling row pixel.
In decryption process, the other user (user2) who receive the
modified pixel image has to perform the reverse process.
Before start reverse procedure user must have to enter secret
key. Firstly performs the reverse cross-over algorithm,
modified pixel image is converted into stego image by
reverse shifting row and column pixel. They are having the
secret shared key to retrieve the secret message from image.
The user provide secret key to separate cipher text and cover
image from stego image. In extraction process the data is
extracted by finding random pixel which contain actual data
in their lsb position of pixel value. The data is collected as
cipher text from cover image. After cipher text convert into
the plaintext by using reverse cryptography , unauthorized
user do not have secret key to decrypt the secret message so,
the proposed system provide multi layered data security for
users .

V. IMPLEMENTATION AND RESULTS
The proposed system work is designed on 64 bit Windows
OS with Core i3 Processor, 4 GB RAM and 1.80GHz using
Java Platform. The original image is in JPG format whereas
SECRET MESSAGE is in a plaintext Format
The original secret message is encrypted first and then it is
embedded into the image by using LSB based cryptography
method. The resultant image is called as stego-image. Crossover algorithm is used to modify the image pixel position of
stego image which is another protection lock for the secret
message and image. Using cross-over concept the column
pixel shuffling happen first and the row pixel shuffling
happens next and the detection of this message is complex.
User who received the modified pixel image has to do the
reverse process and the data hide key to retrieve the Image
and secret message .It is almost impossible for anyone who
will attempt to decrypt the embedded secret message within
that image.
VI. CONCLUSION
We have discussed the process of implementation of
embedding secret message in an image using cryptosystem
with a secret key and steganography along with cross over
algorithm. It can be concluded that normal data security using
steganography and cross-over algorithm technique is applied,
it makes the task of the investigators not feasible to decrypt
the encoded secret message. It provide multi layered data
security for users .The security features of the steganography
are highly optimized using cross-over algorithm. This
proposed system is highly secure & reliable
