Steganography and Its Applications in SecurityIJMER
ABSTRACT: Steganography is the dark cousin of cryptography, the use of codes. While cryptography provides privacy,
steganography is intended to provide secrecy. Steganography is a method of covertly communicating. Steganography is a
process that involves hiding a message in an appropriate carrier for example an image or an audio file. The carrier can then
be sent to a receiver without anyone else knowing that it contains a hidden message. This is a process, which can be used for
example by civil rights organizations in repressive states to communicate their message to the outside world without their
own government being aware of it. In this article we have tried to elucidate the different approaches towards implementation
of Steganography using ‘multimedia’ file (text, static image, audio and video). Steganalysis is a newly emerging branch of
data processing that seeks the identification of steganographic covers, and if possible message extraction. It is similar to
cryptanalysis in cryptography. The technique is ancient emerging monster that have gained immutable notice as it have
newly penetrated the world of digital communication security. Objective is not only to prevent the message being read but
also to hide its existence.

Enhancement of Payload Capacity for Image Steganography based on LSBEditor IJCATR
In this result paper we will show the implementation result of our proposed method. Steganography is an art and
science of Hide the data in a cover image using some techniques that it remains undetected by the unauthorized access. We hide
the data in a manner that the stego image looks like a single entry by any third person. No one has doubt that the image is the
stego image. We use some different methods that keep data to be secret. It is a powerful tool for security with which we can
keep the data secret behind an object. An object may be Text, Audio, Video, and Image. The factor that affects the steganography
methods are PSNR, MSE, Payload Capacity and BER. Security of data will be shown by the Histogram of picture.

Using SBR Algorithm To Hide The Data Into The JPEG ImageCSCJournals
Data hiding is the art of hiding data for various purposes such as--- to maintain private data, secure confidential data. Well known technique is the Steganography; Steganography has evolved into a digital strategy of hiding a file in some form of multimedia, such as an image, an audio file or even a video file. This paper presents a new Steganography technique in spatial domain for encoding extra information in an image by making small modifications to its pixels. The proposed method focuses on one particular popular technique, Least Significant Bit (LSB) Embedding. Instead of using the LSB-1 of the cover for embedding the message, LSB-2 has been used to increase the robustness of system. and protect the message against the external influences such as noise, filter, compression…etc.[Using SBR Algo].
For more protection to the message bits a Stego-Key has been used to permute the message bits before embedding it. An experimental result of the modified method shows that this paper helps to successfully hide the secret data into the image file with minimum distortion made to the image file.

International Journal of Computational Engineering Research(IJCER) is an intentional online Journal in English monthly publishing journal. This Journal publish original research work that contributes significantly to further the scientific knowledge in engineering and Technology.
steganography system uses two algorithms, one for embedding and one for extraction. The embedding process hides a secret message within a cover image/video. The result of embedding process is called stego image.
The main advantage is that the secret message will not be accessed if a third party tries to intercept the cover media.
A Steganography LSB technique for hiding Image within Image Using blowfish En...IJRES Journal
Steganography refers to information or a file that has been hidden inside a digital image, video
or audio file. There are different carrier file formats can be used such as Text Steganography, Image
Steganography, Audio/Video Steganography, but Image Steganography are the most popular because of their
frequency on the Internet. It is the first common methods used for hiding the information in the cover image.
The Least Significant Bit (LSB) steganography is one such technique in which least significant bit of the image
is replaced with data bit. steganographic algorithm for 8bit (gray scale) or 24 bit (colour image) is presented in
this paper. Sometime steganography will not cover the total security of secret massage. So an additional security
need to the secret massage. For this purpose blowfish encryption Algorithm is used in the proposed
Steganographic system This work is concerned with implementing Steganography for images, with an
improvement security and image quality.
The experimental result shows that the stego-image is visually indistinguishable from the original cover-image
It comes under the assumption that if the feature is visible, the point of attack is evident, thus the goal here is
always to cover up the very existence of the embedded data. and that the algorithm has a high capacity and a
good invisibility.
A Cryptographic Key Generation Using 2D Graphics pixel ShufflingIJMTST Journal
Now a day with incredible change in social media network like mobile communication and computer, all
type of a data such as audio, video, images are used for the communication .Privacy for that data is an
important issue .Cryptography is one of the technique used for stopping unauthorized access and increasing
integrity of that data. In research area encryption and decryption scheme is used based on image pixel
shuffling and transposition. For security purpose we can use cipher algorithm for generating key using RGB
values of the pixel instead of using only pixel values. For that purpose in our proposed system we are using
m*n size image on which different operations can be performed. Our proposed system is more secure as
compare to existing system.

CFD Simulation of By-pass Flow in a HRSG module by R&R Consult.pptxR&R Consult
CFD analysis is incredibly effective at solving mysteries and improving the performance of complex systems!
Here's a great example: At a large natural gas-fired power plant, where they use waste heat to generate steam and energy, they were puzzled that their boiler wasn't producing as much steam as expected.
R&R and Tetra Engineering Group Inc. were asked to solve the issue with reduced steam production.
An inspection had shown that a significant amount of hot flue gas was bypassing the boiler tubes, where the heat was supposed to be transferred.
R&R Consult conducted a CFD analysis, which revealed that 6.3% of the flue gas was bypassing the boiler tubes without transferring heat. The analysis also showed that the flue gas was instead being directed along the sides of the boiler and between the modules that were supposed to capture the heat. This was the cause of the reduced performance.
Based on our results, Tetra Engineering installed covering plates to reduce the bypass flow. This improved the boiler's performance and increased electricity production.
It is always satisfying when we can help solve complex challenges like this. Do your systems also need a check-up or optimization? Give us a call!
Work done in cooperation with James Malloy and David Moelling from Tetra Engineering.

It contains various customized modules for effectively maintaining automobiles and stock information accurately and safely.
When the automobile is sold to the customer, stock will be reduced automatically. When a new purchase is made, stock will be increased automatically. While selecting automobiles for sale, the proposed software will automatically check for total number of available stock of that particular item, if the total stock of that particular item is less than 5, software will notify the user to purchase the particular item.
Also when the user tries to sale items which are not in stock, the system will prompt the user that the stock is not enough. Customers of this system can search for a automobile; can purchase a automobile easily by selecting fast. On the other hand the stock of automobiles can be maintained perfectly by the automobile shop manager overcoming the drawbacks of existing system.
Cosmetic shop management system project report.pdfKamal Acharya
Buying new cosmetic products is difficult. It can even be scary for those who have sensitive skin and are prone to skin trouble. The information needed to alleviate this problem is on the back of each product, but it's thought to interpret those ingredient lists unless you have a background in chemistry.
Instead of buying and hoping for the best, we can use data science to help us predict which products may be good fits for us. It includes various function programs to do the above mentioned tasks.
Data file handling has been effectively used in the program.
The automated cosmetic shop management system should deal with the automation of general workflow and administration process of the shop. The main processes of the system focus on customer's request where the system is able to search the most appropriate products and deliver it to the customers. It should help the employees to quickly identify the list of cosmetic product that have reached the minimum quantity and also keep a track of expired date for each cosmetic product. It should help the employees to find the rack number in which the product is placed.It is also Faster and more efficient way.

2. CRYPTOGRAPHY & STEGANOGRAPHY
CRYPTOGRAPHY :
The art of protecting information by transforming it
(encrypting it) into an unreadable format, called cipher text.
Only those who possess a secret key can decipher (or decrypt)
the message into plain text.
STEGANOGRAPHY:
Steganography is basically referred as hidden writing. It is
entirely different from cryptography. In cryptography ,we
basically perform the encryption and decryption by changing
the text into another form.
3. STEGANOGRAPHY
But in steganography, we do not change the text into
another form but just hide it into the image or audio so
that the attacker doesn’t know about the hidden message.
4. RSA algorithm is a part of cryptography in which a text
message is hidden in some other form. Using steganography
alongwith RSA algorithm works for 2-level security.
Introduction to RSAAlgorithm
5. TYPES
Types of Steganography:
1. Image Steganography
2. Text Steganography
3. Video Steganography
4. Protocol Steganography
5. Audio Steganography
6. HOW STEGANOGRAPHYWORKS
Now the question is how steganography works!!
In steganography first we select the text or any file that we
want to send to another person.
Then we select the image or audio file in which we want
to hide our file(containing message).
7. Then we use the steganography software for encryption.
After encryption the text file is now converted in an image
file which contains our confidential data.
Then the receiver will also use the same software for
decryption.
8. IMAGE STEGANOGRAPHY
WITH RSAALGORITHM
How the image steganography works:
Before encrypting file into image file, we use the well
defined RSA Algorithm to increase the security of the data
transmission.
Then, we use this encrypted message to be encrypted
o9nce again into the image file.
9. Every image is formed of the pixels. There are a number
of pixels in the image. Every pixel is formed of 24 bits.
Each pixel has 8 bits of red color, 8 bits of green color and
8 bits of blue color(RGB).
10. Also the file that we want to send to the receiver is also formed
from a number of bits.
Now the next step is to store every 3 bits of the file in every
pixel’s Least Significant bit (LSB) i.e. 1-1 bit in 8th bit of red ,
blue, green color bits.
In this way our encryption will be done.
In this way, decryption can also be performed by extracting the
8th bit of every color from each pixel.
11.
12. CODE ANALYSIS
First we extract the image by using
Image im=Image.fromfile(imagepath);
Get the height and width by im.height and im.width
Get the pixel info by using
Bitmap bt=new bitmap(im);
13. IMAGE STEGANOGRAPHY
Now we extract the file and get the fileinfo by using
FileInfo fi=new FileInfo(filepath)
We convert the file into stream of bytes by using
fc=File.ReadAllBytes(file path)
14. Now we perform the encryption
In encryption function, we start a loop and in loop we access
every byte of the file 3 times .
We also use the functions ‘byte2bool’ and ‘bool2byte’ which
converts byte into bits and vice-versa
15. Starting from LSB, in the first iteration we first put 3 bits
of the file in the red pixel, then in the green one and in
third i.e. blue we put 2 bits.
The chromatic influence of blue color is maximum for
human eye so we change only 2 bits of it.
When all the bytes of the file are not able to store in the
last bits of every color then we start to replace the 7 th bit
of every color.
16. In this way the storing capacity of the image file increases
but little noise is also increased in the image
In the same way we can perform the decryption
