This document discusses digital steganography, which is a method of hiding secret messages within other digital data, such as images. It proposes using a new technique of image steganography that embeds encrypted data into the least significant bit of image pixel values using a hash function and RSA encryption for added security. The objectives are to develop a security tool to hide messages in digital media in a way that is not detectable by humans. It analyzes existing steganography methods and their disadvantages, then proposes a system using LSB substitution to replace pixel bit values with encrypted message bits to create a stego-image. The document outlines the modules, algorithms, advantages and future enhancements of the proposed digital steganography system.
Improved LSB Steganograhy Technique for grayscale and RGB imagesIJERA Editor
A number of techniques are there to converse securely. Encryption and cryptography are enabling us to have a secure conversation. To protect privacy and communicate in an undetectable way it is required to use some steganography technique. This is to hide messages in some other media generally called cover object. In todays digital world where images are a common means of information sharing, most of the steganography techniques use digital images as a carrier for hiding message. In this paper a LSB based technique is proposed for steganograpgy. This technique is different from standard LSB technique that along with message hidden in LSB bits a part of message also resides at other selective bits using a key. The method is developed to increase the payload capacity and make detection impossible.

Review Paper on LSB Based Stegnography to Enhance Image Securityijtsrd
Steganography is the technique of hiding a secret message or information in a cover message like an image, text or sound in such a way that only the desired or intended recipient knows about the existence of the secret data. It can be defined as the study of invisible communication which usually deals with the technique of hiding the existence of the secret message. The hidden message may be in the form of text, image, audio and video etc. An image after inserting the secret message into it by using a stego key is known as a stego image. Nowadays steganography is important due to an exponential growth in secret communication by potential computer users over the internet. In this paper we have analyzed the various steganography techniques and observed that the security of the secret message can be enhanced by random selection of the pixels for substitution in LSB steganography. Further the error metrics PSNR Peak Signal to Noise Ratio should be high and MSE Mean Square Error should be low indicating good quality re construction.

encryption based lsb steganography technique for digital images and text dataINFOGAIN PUBLICATION
Digital steganography is the art and science of hiding communications; a steganographic system thus embeds secret data in public cover media so as not to arouse an eavesdropper’s suspicion. A steganographic system has two main aspects: steganographic capacity and imperceptibility. However, these two characteristics are at odds with each other. Furthermore, it is quite difficult to increase the steganographic capacity and simultaneously maintain the imperceptibility of a steganographic system. Additionally, there are still very limited methods of Steganography to be used with communication protocols, which represent unconventional but promising Steganography mediums. Digital image Steganography, as a method of secret communication, aims to convey a large amount of secret data, relatively to the size of cover image, between communicating parties. Additionally, it aims to avoid the suspicion of non-communicating parties to this kind of communication. Thus, this research addresses and proposes some methods to improve these fundamental aspects of digital image Steganography. Hence, some characteristics and properties of digital images have been employed to increase the steganographic capacity and enhance the stego image quality (imperceptibility). Here, the research aim is identified based on the established definition of the research problem and motivations. Unlike encryption, Steganography hides the very existence of secret information rather than hiding its meaning only. Image based Steganography is the most common system used since digital images are widely used over the Internet and Web. However, the capacity is mostly limited and restricted by the size of cover images. In addition, there is a tradeoff between both steganographic capacity and stego image quality. Therefore, increasing steganographic capacity and enhancing stego image quality are still challenges, and this is exactly our research main aim. To get a high steganographic capacity, novel Steganography methods were proposed. The first method was based on using 8x8 non-overlapping blocks and quantization table for DCT with compression. Second method incorporates the DWT technique, with quality of any stego images as enhanced to get correct hidden image. And last LSB as to store images with Key type security built in.
EMPIRICAL STUDY OF ALGORITHMS AND TECHNIQUES IN VIDEO STEGANOGRAPHYJournal For Research
Steganography is the art and science of hiding the actual important information under graphics, text, cover file etc. These techniques may be applied without fear of image destruction because they are more integrated into the image. Information can be in the form of text, audio, video. The purpose of steganography is to covert communication and to hide a message from a third party or intruder. Steganography is often confused with cryptography because the two are similar in the way that both are used to protect confidential information. Though there are many types of steganography, video Steganography is more reliable due to high capacity image, more data embedment, perceptual redundancy etc. This research paper deals with various Video Steganography techniques and algorithms including Spatial Domain, Pseudorandom permutations, TPVD (Tri-way pixel value differencing), Motion Vector Technique, Video Compression, and Motion Vector Technique. The Video compression which uses modern coding techniques to reduce redundancy in video data has been also studied and analyzed. In fact, Video compression operates on square-shaped groups or blocks of neighboring pixels, often called macro blocks. These pixel groups or blocks of pixels are compared from one frame to the next and the video compression code sends only the differences within those blocks. Generally, the motion field in video compression is assumed to be translational with horizontal component and vertical component and denoted in vector form for the spatial variables in the underlying image, such as three steps search, etc. The study also discusses and focusses on the evolution of the Video Steganography techniques and algorithms over the years based on its application and subsequent merits and demerits. Further, Advanced Video Steganography Algorithm/Bit Exchange Method based on the bit shifting and XOR operation in the secret message file has been studied and implemented. The encrypted secret message is embed in the cover file in alternate byte. The bits are substituted in LSB & LSB+3 bits in the cover file. Finally, the simulation and evaluation of the above mentioned approach is performed using MATLAB tools.

Impact of Message Size on Least Significant Bit and Chaotic Logistic Mapping ...ijtsrd
Steganography is the technique of hiding information in other objects. Although many carrier objects can be used, digital images are the most popular because of their usage over the internet. For this purpose, many types of images steganographic techniques have been invented. Each of them has both pros and cons. It depends on the complexity, hiding capacity, security, and so on. In our research, we studied the two most popular techniques of image steganography, least significant bit LSB and chaotic logistic mapping to find the similarities, dissimilarities, and many other factors. In this paper, we presented a detailed comparison of the LSB and chaotic logistic mapping based image steganography for various carrier images and messages.

An important topic in the exchange of confidential messages over the internet is the security of information conveyance. For instance, the producers and consumers of digital products are keen to know that their products are authentic and can be differentiated from those that are invalid. The science of encryption is the art of embedding data in audio files, images, videos or content in a way that would meet the above security needs. Steganography is a branch of data hiding science which aims to reach a describe level of security in the exchange of private military and commercial data which is not clear. This system is proposed to hide the text information files within the image based on the LSB method in order to meet security requirement such as confidential and integrity. The least significant bit is the bit which is farthest to the right and holds the least value in a multi bit binary number. This system is implemented by using C programming.

Design and Implementation of Lifting Based Wavelet and Adaptive LSB Steganogr...Dr. Amarjeet Singh
Image steganography is an art of hiding images
secretly within another image. There are several ways of
performing image steganography; one among them is the
spatial approach. The most popular spatial domain approach
of image steganography is the Least Significant Bit (LSB)
method, which hides the secret image pixel information in the
LSB of the cover image pixel information. In this paper a
LSB based steganography approach is used to design
hardware architecture for the Image steganography. The
Discrete Wavelet Transform (DWT) is used here to transform
the cover image into higher and lower wavelet coefficients
and use these coefficients in hiding the secret image. the
design also includes encryption of secret image data, to
provide a higher level of security to the secret image. The
steganography system involving the stegno module and a
decode module is designed here. The design was simulated,
synthesized and implemented on Artix -7 FPGA. The
operation hiding and retrieving images was successfully
verified through simulations.

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.

A Strategic Approach: GenAI in EducationPeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

In Odoo, the multi-company feature allows you to manage multiple companies within a single Odoo database instance. Each company can have its own configurations while still sharing common resources such as products, customers, and suppliers.
The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

Francesca Gottschalk from the OECD’s Centre for Educational Research and Innovation presents at the Ask an Expert Webinar: How can education support child empowerment?
Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.
2. ABSTRACT
Steganography is a method of hiding secret messages in a cover object while communication
takes place between sender and receiver.
Security of secret or important information has always been a major issue from the past times
to the current time. It has always been the interested topic for researchers to develop secure
techniques to send data without revealing it to anyone other than the receiver.
Therefore from day to day researchers have developed many techniques to fulfill secure
transfer of data and steganography is one of them. In this thesis we have developed a new
technique of image steganography inside the embedding the encrypted Data file or message
using Hash-LSB with RSA algorithm for providing more security to data as well as our data
hiding method.
The developed technique uses a hash function to generate a pattern for hiding data bits into
LSB of RGB pixel values of the carry image.
3. AIM
Hiding sensitive information vital for security purposes
Securing private files and documents
4. OBJECTIVE
The main objectives of our project are to product security tool based on
steganography techniques to hider message carried by stego-media which
should not be sensible to human beings and avoid drawing suspicion to the
existence of hidden message.
5. Information Hiding -Introduction
Purpose:
Hiding sensitive information vital for security purposes
Securing private files and documents
Hiding information - 3methods - Cryptography, Steganography, Watermarking.
Cryptography - Data to be hidden is coded
several techniques ; sophisticated
visually obvious to be encrypted; appears non-sensical
Watermarking
Applies a copyright label ; prevents illegal use of content
Improper removal causes degradation of original information
Steganography -hiding information by using another information as a cover.
Elements:
cover component, message component, stego component.
6. Steganography -Introduction
Types:
Text steganography
Image steganography
Video steganography
Audio steganography
Image steganography is widely used.
Images contain redundant information.
Easy to manipulate few pixels without affecting visual data observably
Slight changes in RGB values undetected by human eye (HVS) - Psychovisual
redundancy.
Types: Text in image ; image in image
7. PROBLEM STATEMENT
The former consists of linguistic or language forms of hidden writing. The later, such as invisible ink, try
of hide messages physically. One disadvantage of linguistic steganography is that users must equip
themselves to have a good knowledge of linguistry.
In recent years, everything is trending toward digitization. And with the development of the internet
technology, digital media can be transmitted conveniently over the network. Therefore, messages can be
secretly carried by digital media by using the steganography techniques, and then be transmitted through
the internet rapidly Steganography is the art of hiding the fact that communication is taking place, by
hiding information in other information.
Many different carrier file formats can be used, but digital images are the most popular because of their
frequency on the internet. For hiding secret information in images, there exists a large variety of
steganography techniques some are more complex than others and all of them have respective strong and
weak points. So we prepare this application, to make the information hiding more simple and user
friendly.
8. PROBLEM ANALYSIS
Steganography takes cryptography a step farther by hiding an encrypted message so that no
one suspects it exists. Ideally, anyone scanning your data will fail to know it contains
encrypted data.
Data is first encrypted by the usual means and then inserted, using a special algorithm, into
redundant (that is, provided but unneeded) data that is part of a particular file format such as
a JPEG image.
Think of all the bits that represent the same color pixels repeated in a row. By applying the
encrypted data to this redundant data in some random or non-conspicuous way, the result will
be data that appears to have the "noise" patterns of regular, non- encrypted data. A trademark
or other identifying symbol hidden in software code is sometimes known as a watermark.
9. EXISTING SYSTEM
Data hiding for vector quantization (VQ)-based images focuses on the problem of embedding
secret data into a cover VQ-based image to achieve secret communication and data protection.
VQ-based data-hiding methods into four no overlapping groups according to their reversibility and
output formats, introduce the details of the representative methods, summarize the features of the
representative methods, and compare the performance of the representative methods using peak
signal-to-noise ratio, capacity of secret data, and bit rate.
An irreversible method is very likely a VQ-based data-hiding method that produces a stego-image
as its output, and it can embed more secret data than a reversible method. Nonstandard encoding
methods (e.g., joint neighboring coding) are becoming popular in reversible data hiding since they
can increase the capacity for embedding the secret data
10. DISADVANTAGE
Huge number of data, huge file size, so someone can suspect about it.
If this techniques is gone in the wrong hands like hackers, terrorist, criminals then this
can be very much dangerous.
11. PROPOSED SYSTEM
Steganography is the art of hiding information and an effort to conceal the existence of the
embedded information.
It serves as a better way of securing message than cryptography which only conceals the
content of the message not the existence of the message.
Original message is being hidden within a carrier such that the changes so occurred in the
carrier are not observable. In this paper we will discuss how digital images can be used as a
carrier to hide messages.
This paper also analyses the performance of some of the steganography tools. Steganography
is a useful tool that allows covert transmission of information over an over the
communications channel. Combining secret image with the carrier image gives the hidden
image. The hidden image is difficult to detect without retrieval
12. ADVANTAGE
Alterations not visible to the human eye
Simple & easiest way of hiding Information
Hidden data can be distributed more evenly over the whole image in such a
way as to make it more robust
21. Methods:
LSB substitution method:
Deals with substituting LSB bits of corresponding pixels in image to store the text
message or another image as a message.
Block method:
blocks of the image are considered and DCT (discrete cosine transform) is done in
order to break them.
Each block is then subdivided into 64 parts (DCT coefficients).
These coefficients are modified i.e. the color gets modified a little by storing some
text or another image in it.
Palette modification:
Every image uses a set of color values.
Palette Modification replaces the unused colors within an image’s color palette
with colors that represent the hidden message.
22. LSB substitution method -Algorithm:
In the current project, emphasis is given to this
method.
Simplicity
Mostly Imperceivable
One of the channels among RGB can be chosen, and LSB of its pixels altered
or all the channels could be used.
Example:
(a) binary form of message to be hidden
(b) few pixel values on cover image
(c) LSB altered
23. Algorithm:
1. Input the message to be hidden. (either image
or text)
2. Check the maximum number of bits that can be
accepted by the cover image
3. Replace the LSB bits of the pixels in cover
image with the binary representation of the
message. => we obtain Stego image
Either color image (RGB) or grayscale image can
be used as a cover image.
In case of color image, 24bit image i.e. 8bits are
present for each for RGB so more number
information pixels can be stored.
Modification can be done to either just the last 1
bit or 2,4 or more bits depending on
requirement.
24. CONCLUSTION
It is observed that through LSB Substitution Steganographic method, the
results obtained in data hiding are pretty impressive as it utilizes the simple
fact that any image could be broken up to individual bit-planes each
consisting of different levels of information.
It is to be noted that as discussed earlier, this method is only effective for
bitmap images as these involve lossless compression techniques. Also, in this
project grey-scale images have been used for demonstration.
But this process can also be extended to be used for color images where,
bitplane slicing is to be done individually for the top four bit-planes for each
of R, G, B of the message image, which are again to be placed in the R, G, B
planes of the cover image, and extraction is done similarly.
25. FUTURE ENHANCEMENT
The future work on this project is to improve the compression ratio of the
image to the text. This project can be extended to a level such that it can be
used for the different types of multimedia files.
