Abstract
— Steganography is the art of hiding the fact where communication is taking place, by hiding information in other information. Steganography becomes more important as more people join the cyberspace revolution.. In contrast to cryptography, it is not to keep others from knowing the hidden information but it is to keep others from thinking that the information even exists. Steganography include an array of secret communication methods that hide the message from being seen or discovered. 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. Different applications may require absolute invisibility of the secret information, while others require a large secret message to be hidden. This project report intends to give an overview of image steganography, its uses and techniques. In addition to this our project also adds security to both the data hidden and the image that carries the information. Security is provided by Encrypting the data that is sent in the image and again encrypting the image that carries the information using AES algorithm. This encryption of the data and image thus provides double security layer.

A Literature Review on Image Steganography Using AES
IRJET, 2022
The art of concealing / hiding information or data bits on a cover or carrier file is known as Steganography. We can envisage Steganography being utilized in nearly any sort of file, including image files. Masking information, such as text, photos, or audio files, within other image files is known as Image Steganography. Image steganography enables the communication between one another, secretly and stealthily. To add even more security, the secret message, which is contained within the image file, is encrypted. Data compression is an important aspect of information security since compressed data is more secure and easier to manage. By encrypting data and hiding it from attackers, the primary purpose is to save physical space on storage devices and reduce the time it takes to transport data over the internet. The secret message is then coded and compressed before being combined into the compressed cover image file. The result stego-image is then sent to the receptor where the message is uncompressed, decoded and retrieved. This survey focuses on the methods implemented by authors of several works for hiding and securing the information.
SECURED STEGANOGRAPHY APPROACH USING AES
TJPRC, 2013
Today’s cyber world is growing rapidly over Internet technologies & its applications needing high level of safeguard for expensive data during transmission over the open communication channel. Image steganography is a technique for hiding information into a cover image. Least Significant-Bit (LSB) replacement based method is most common steganographic technique in spatial domain owing to its simplicity and hiding capacity. Most of existing approaches focus on the embedding strategy with less consideration to the pre-processing such as encryption of secrete image. The conventional steganography algorithm does not provide the preprocessing required in image for better security and privacy. The proposed work presents an exclusive technique for Image steganography based on the Advance Encryption Standard (AES) using 128 bit block size of plaintext & 128 bits of Secrete key. The preprocessing provide high level of security as extraction of image is not possible without the knowledge of mapping rules of AES and secrete key .
Dual Layer Security of data using LSB Image Steganography Method and AES Encryption Algorithm
In today’s scenario security of data is very big challenge in any communication. Numerous data security and hiding algorithms have been developed in the last decade. The Digital image Steganography is science of hiding sensitive information in another transmission medium to achieve secure and secret communication. In this paper we present the dual layer of security to the data, in which first layer is to encode data using Least Significant Bit image steganography method and in the second layer encrypt the data using Advance Encryption Standard Algorithm. Steganography does not replace the encryption of data, instead it provides extra security feature to it. In our work secret text message is hiding behind the digital image file and this image file is then encrypted using AES encryption algorithm.
PROPOSED AES FOR IMAGE STEGANOGRAPHY IN DIFFERENT MEDIAS
In this paper, the author presents an enhanced version of modified AES for image-audio steganography technique. The proposed technique improves the security level of encryption and steganography process. Digital image processing is a wide area for research. Images are widely used today. Processing on images means some editing, preprocessing, restoration, compression, steganography and encryption. Steganography is concealing secret information into cover information. Encryption is mainly used for encoding the content of an image into something that cannot be understandable by unauthorized persons. Authorized are those who have the legal access to the content. Nowadays everyone is after information so; it becomes the need today to secure the (confidential) information. The proposed AES technique is an enhancement of modified AES method, which focuses on improving the security of steganography images. Modified AES is described in four steps: first step is key expansion, second is sub bytes modification, third is new shift rows and at last mixing of columns is applied to the matrix. This technique will provide better security and good quality encryption and decryption. Results shows that this method takes less time with the high quality of encrypted image
Secured Transmission of Information using Steganography and AES Algorithms
The objective of image processing is to extract important information from images. The information can be in images or some vital data which can useful for further computing and analysis. In this paper a technique is evolved for encrypting the plain text multiple times. The ASCII codes(0-255) for the text information is utilized and even if intruder applies the brute force method for any attack, then he/she must have to exercise a trail for 256! times which is quite absurd. Moreover, the multiple encryption method makes the system further secured. This paper focuses on a technique that would offer better and secured technique to enable secret data transmission for commercial financial transactions using steganography and AES algorithm.
Images Encryption Method using Steganographic LSB Method, AES and RSA algorithm
Nonlinear Engineering, 2017
Vulnerability of communication of digital images is an extremely important issue nowadays, particularly when the images are communicated through insecure channels. To improve communication security, many cryptosystems have been presented in the image encryption literature. This paper proposes a novel image encryption technique based on an algorithm that is faster than current methods. The proposed algorithm eliminates the step in which the secrete key is shared during the encryption process. It is formulated based on the symmetric encryption, asymmetric encryption and steganography theories. The image is encrypted using a symmetric algorithm, then, the secret key is encrypted by means of an asymmetrical algorithm and it is hidden in the ciphered image using a least significant bits steganographic scheme. The analysis results show that while enjoying the faster computation, our method performs close to optimal in terms of accuracy.
Two New Approaches for Image Steganography Using Cryptography
Two New Approaches for Image Steganography Using Cryptography, 2015
The process of jumbling up the contents of a secret message so as to secure it, is known as cryptography, whereas the process of hiding the very existence of a secret message is known as steganography. The term "steganography" describes the method by which the contents of a secret message are concealed inside some other medium, so as to avoid any kind of detection by an intruder. In this paper, we have proposed two new approaches wherein both cryptography and steganography are used to encrypt the data and also to conceal these encrypted contents in some other medium. In the first method proposed, we have secured an image by converting it into an encrypted text using S-DES algorithm and a secret key and then concealing this encrypted text in some other image, whereas in the second method, we have secured an image directly by encrypting it using S-DES algorithm and an image key. The contents thus obtained are concealed inside another image so as to hide its very existence. Both these techniques have been tested and it has been observed that they prevent the possibilities of steganalysis also.

New Approaches to Encrypt and Decrypt Data in Image using Cryptography and Steganography Algorithm
International Journal of Computer Applications, 2016
Nowadays, network has important roles for transferring data accurately and fast from source to a destination. The data is not secure enough to transfer highly confidential. The security of information has become one of the principle challenges of resource sharing with data communication over computer network. Cryptography and Steganography are two methods for protecting data from intruders while transferring over an open channel network. Cryptography is a method to encrypt data and steganography is the art and science of hiding secret message in a cover image. In this paper a Hash Least Significant Bit (H-LSB) with Affine cipher algorithm has been proposed for providing more security to data in a network environment. First we encrypt the data with the new cryptography algorithm and then embed in the image. Eight bits of the secret message are divided into 3, 3, 2 and embedding into the RGB pixels values of the cover image respectively. A hash function is used to select the particular position of insertion in LSB bits. This system allows a message sender to select keys to encrypt the secret message before embedding into the image and a receiver is used the keys to decrypt the message. Receiver can be decrypted the encrypt message with incorrect the keys but to a different form from the original message. This system has the ability to provide better security while transferring the secret message from one end to the other end in network environment.

International Journal of Advanced Trends in Computer Science and Engineering , 2021
The transmission of information through any channel of correspondence needs solid encryption procedures with the end goal of information security. The computerized watermarking assumes a significant part in inserting data into an advanced picture signal, for the check and character of its proprietors. In discrete wavelet change, "investigation channel bank" can be utilized for dissecting picture signals by going through. The channel bank comprises high and low pass channels at every deterioration stage. In this paper, a technique to consolidate steganography (Least Significant Method-LSM) and cryptography Advanced Encryption Standard (AES) is thought to give a safer method to information transmission through any unstable or public organizations. Prior to inserting the content in the picture, the text is scrambled utilizing AES calculation. Utilizing least significant bit (LSB) strategy, encoded the text installed in low-low (LL) subband wavelet decayed of a picture. Converse wavelet changes applied will lead to the output picture is communicated to the recipient. Presently at the collector's end, the picture changed utilizing wavelet and encoded text will be extricated by utilizing the LSB technique. This paper shows how AES calculation is utilized in the decoding of the outcome.

Performance Evaluation of Steganography and AES encryption based on different formats of the Image
IJARCCE, 2015
During the recent times, there has been tremendous growth in transfer of data across the globe which ultimately has boosted data communication over the computer networks. For any data communication network, the information content security of the messages is of prime concern. Steganography and Cryptography are two different data hiding techniques. Steganography puts a cover onto the messages by some other form of digital media whereas Cryptography on the other hand performs the encryption of the message. In this paper, we present a combination of both these techniques wherein the text is first hidden into some form of cover image using Least significant bit (LSB) hiding method and then encryption using Advanced Encryption Standard (AES) is performed on to the stego image. The combination of both these algorithm will certainly ensure high degree of security, integrity, capacity and robustness to the embedded data. Using GUI based MATLAB simulation, a comparative analysis is being made by employing different formats of the images for learning variations in performance evaluation parameters such as delay, Peak Signal to Noise Ratio (PSNR), Mean Square Error (MSE), and Absolute Mean Square Error (AMSE). The objectives of this paper are to provide security against visual as well as statistical attacks and to ensure better quality of received information.

International journal of engineering research and technology, 2019
Steganography is the advanced methodology for concealing secret data than the other strategies used to date. There are often cases when it is not possible to send messages openly or in encrypted form. This is where steganography play its role. While cryptography provides privacy which is intended to provide secrecy. Steganography aims to hide the secret messages and also for communication and transferring of data. So nobody aside from the licensed sender and receiver are tuned in to the existence of the key information. This paper intends to give an overview of image steganography and its uses and hiding the files (text file, audio file, video file, image file, etc.,) by using LSB and AES algorithm where AES is used for password protecting system so that if anyone can find the Stego-image they will not read the message because data is still in the encrypted form and LSB is used for hiding the data.
