ABSTRACT
Recently, the mode of living became more complicated without computer systems. The techniques of
camouflage information have acquired a vital role with the requirement of intensifying trade of multimedia
content. Steganography is the technique that utilizes disguise in a way that prohibits unauthorized access
from suspicion of the existence of confidential information exchanged during communication channels
between the connected parties. In this paper, an integrated image steganographic system is designed to
conceal images, messages or together where the mainly deliberate the improvement of embedding capacity
through embedding text with image simultaneously. For that purpose, used matrix partition to partition the
secret image then embedded each partition separately after scrambling each pixel by replacing msb instead
of lsb to provide the second level of security furthermore to steganography. The simulation results clarify
the better performance of the proposed algorithms.

1. INTRODUCTION
In this contemporary age, computers and the internet are greater communicating media that join
varied portions of the globe. Therefore, people can easily transfer data. Consequently, the safety
and security stay an important question. The requirement to answer this question has guided to
the improving of steganography system [1].
The name Steganography is formed from a Greek expression, “Steganos” denote "covered " and
“Graptos” denote "writing ", which denote concealed communicating. In this technique, the
existence of a message is camouflage[2] .
Steganography is closely associated with cryptography[3]. Cryptography is the most significant
realm in computer security. Actually, it is a technique for exchanging private data through an
open system correspondence, with the goal that as it were the recipient who has the mystery key
can peruse the encoded messages, which may be reports, telephone discussions, images, or
different types of information[4].Unlike cryptography where communicating is observable, but
the content is kept private, steganography is the scientific discipline that hiding data within some
data media [3].There are five primary class of cover which can be utilize for steganography
technique [5].
Figure 1.demonstrate the kind of media that utilized as a cover for steganography technique.
The Image steganography deals with the information that is concealed in the image and can be
performed in two domains [6]. The spatial domain where the private data is concealed by

Despite the fact that the aim of the cryptography and steganography system are similar, which is
to supply guard end to end data communicating, their meanings of robustness to the offense are
dissimilar. A cryptography framework is considered as crack when the outsider acquire accesses
to decrypt information, while the steganography framework is considered as crack when the
outsider acquires the appearance of mystery information[8].
Steganography used in broad of applications such as military constitution for protecting the
transmission of private information, intelligence service, in intelligent identity cards where
particular details are hidden in the picture of a person for copyright restrain, medical imaging
where patient’s information is concealed within image give security of information and decrease
transmitting time[9].
In this paper, we present a new partition steganography techniques utilized LSB algorithm in
spatial domain to hide images, messages or together using RGB color and grayscale as cover
images. The remains section of the paper is organized as listed below:
Section 2 shows The literature review. Section 3 explains Model of image Steganography system
with measurement. Section 4 shows the proposed approach. The results are illustrated in section
5, and the conclusions demonstrated in Section 6 pursue the pertinent references.
2. LITERATURE REVIEW
S. Ali, et. al. [10] proposes a spatial domain LSB replacement method for grayscale image
concealed and Arnold transform is applied to ensure security. The proposed system is verified
against a series of standard images and it has features of imperceptibility and security but the
limitation of the method is being slow in extracting algorithm when utilizing large size image
greater than 160*160. Also, it employs images of the same dimensions.
Kh. A. Al-Afandyi, et al. [11] propose a data hiding scheme based on cropping a color image and
separate The private message into section identical image crops and Each section is concealed
into an image crop according to private sequence utilize the LSB. The proposed approach
provides higher security for the private message.
Y. Parti, et al.[12] propose a steganographic approach for grayscale image hidden based on
spatial domains which utilize three times the XOR operation and utilizes three MSB bits 8th, 7th,
and 6th as keys to cipher the private message earlier and then concealed it utilizes the LSB
algorithm. The proposed methods provide another level of security with a simple operation.
S. Mahdie [13] suggests a method based on Selected Least Significant Bit to hide data into color
images utilize magic square. The proposed algorithm has two strong points; the private text is
dispersed among the image using magic square order, which raises the complexity of the
algorithm, and the secret bits are altered by their Xor with the corresponding Selected Least
Significant Bit value but the Mean Square Error approach 10.81.
Kh. F. Rafat, et al.[14] propose Secure image Steganography where the secret information is
dispersed irregular into cover image utilize Stego key dependent position where the attacker may
not definite whether the image holds some hidden data . The proposed scheme is difficult to
detect but limited capacity when applied to color image because of used the only blue channel.
V.Shahuse.[15] suggest Sparse Matrix for Steganography in the spatial domain to encode data
such as the key and message which support the security of the algorithm and the proposed is
better in time of execution but lacks cover image size to analyze performance.

K. Joshi, et al.[16] propose a
combine it with cryptography in a spatial domain. In the proposed scheme, the private message is
ciphered employ Vernam cipher and then the cipher is hidden into an image utilizes LSB with
Shifting. The proposed method enhances the security of concealed information but doesn't
determine exactly the number of a bit from LSB that used for data hidden to recognize the total
capacity that available to conceal the private message.
3. IMAGE STEGANOGRAPHY
3.1 MODEL OF IMAGE STEGANOGRAPHY
The entire steganography system is constituent of cover media, stego media, concealing

know for sender and receiver [17]. The steganography system that utilizes images as the cover
media is known as an image steganography where conceal private information into images is the
common employ manner as it can gather benefit of the confined power that associate with the
human visual system and an enormous amount of superfluous data of images th

6. CONCLUSION
In this paper, an integrated image steganographic system based matrix partition utilize RGB color
and grayscale carrier images is proposed to hide text, image, or both, where hiding text with the
image simultaneously in the proposed algorithms provide three features, The first feature seize
the attacker's attention to the amount of data thus supply more protection for private message.
The second feature, offer details about secret image with append secret message embedded in the
cover image simultaneously thus exploit time that consumes when sent them separately and the
third feature uses matrix partition to private image that increase the concealed capacity of the
algorithm. Also, present better performance in terms of speed of execution and extraction. The
simulation results exhibit that our proposed algorithm realize better embedding capacity with the
excellent visual quality of both stego image and extract private image with providing additional
security by using scramble of each pixel furthermore to steganography. The limitation of the
proposed algorithms that stego image loss secret data if exposed to lossy compression because the
algorithm accomplishes in spatial domain using LSB algorithms. As a future work, the proposed
method may be utilized with the encryption algorithms to provide three levels of security and the
proposed method may be also applied in transform domain rather than spatial domain to provide
robustness against attack.
