Reversible Data Hiding in Encrypted Image: A ReviewEditor IJMTER
Recently, more and more attention is paid to reversible data hiding (RDH) in encrypted
images, since it maintains the excellent property that the original cover can be losslessly recovered
after embedded data is extracted while protecting the image content’s confidentiality. All previous
methods embed data by reversibly vacating room from the encrypted images, which may be subject
to some errors on data extraction and/or image restoration. In this survey paper, we discuss about
various methods and algorithms which were used for reversible data hiding (RDH) in encrypted
image to make data hiding process effortless. We also use visual cryptographic approach for
encryption which helps to protect the image during transmission. The scheme is suitable for
authentication based application where collective acceptance and decision making plays an important
role. The main goal is to retrieve the original image with lossless process and minimum computation
during image encryption /decryption by using keyless approach.

This document summarizes a research paper that proposes a new methodology for reducing additive distortion in steganography. The paper introduces a method to embed 2 bits of information in a pixel by altering only one bit plane. This is expected to make detection of covert communication more difficult for steganalysis algorithms compared to altering the least significant bit. The method uses Java for implementation and MATLAB to analyze histograms of original and stego images. Experimental results on embedding secret text in images are presented, along with analysis of the distortion levels and security of the proposed approach.

The document proposes three methods for image steganography to increase hiding capacity: 1) Modifying image edges to increase edge pixels for hiding bits. 2) Selecting lighter color regions and converting to white pixels for hiding. 3) Combining 1) and 2) using a chaotic map to randomly choose edge or region pixels. The LSB technique hides secret bits in the last 2-bits of chosen pixels. Experimental results showed the combined method achieved a PSNR of 62.72 dB, comparable to other techniques.
DEVELOPING ALGORITHMS FOR IMAGE STEGANOGRAPHY AND INCREASING THE CAPACITY DEP...IJCNCJournal
Steganography is a vital technique for transferring confidential information via an insecure network. In
addition, digital images are used as a cover to communicate sensitive information. The Least Significant
Bit (LSB) method is one of the simplest ways to insert secret data into a cover image. In this paper, the
secret text is compressed twice by an Arithmetic coding algorithm, and the resulting secret bits are hidden
in the cover pixels of the image corresponding to the pixels of each of the following three methods, one of
three methods is used in each experiment: The first method, the edges of the image are modified to increase
the number of edges, in the second method the lighter-colored regions are selected, and in the third
method, the two methods are combined together to increase security and keep the secret message
unrecognized. Hiding in each of the previous methods is done by using the LSB technique in the last 2-bit.
The correction approach is used to increase the stego image's imperceptibility. The experimental results
show that with an average message size of 29.8 kb, the average Peak Signal-to-Noise Ratio (PSNR) for the
second proposed (Light regions) method equals 62.76 dB and for the third proposed (Edge and region)
method equals 62.72 dB, which is a reasonable result when compared to other steganographic techniques.
Reversible Image Data Hiding with Contrast EnhancementIRJET Journal
This document proposes a reversible image data hiding technique with contrast enhancement. It aims to embed data into a cover image in a reversible manner while also enhancing the contrast of the cover image. The technique first calculates prediction errors of pixel values in the cover image. It then generates a histogram of the prediction errors and selects carriers for data embedding from peaks in the histogram. Binary secret data is embedded into the carriers by dynamically shifting the prediction error histogram. This allows data to be embedded while increasing cover image quality compared to other reversible data hiding methods. The original cover image can be recovered by extracting the embedded data and reversing the histogram shifts. The technique is meant to achieve a higher peak signal-to-noise ratio than the original cover image after data
This document provides an overview of digital image steganography and steganalysis. It discusses various image steganography techniques including least significant bit modification in the spatial domain, and algorithms like JSteg and F5 that operate in the transform domain. It also covers hybrid techniques like patchwork and spread spectrum. The document compares the techniques based on parameters like invisibility, bit rate, and robustness. Finally, it discusses steganalysis methods for detecting hidden information in images, including techniques based on higher-order image statistics.

IRJET-Securing High Capacity Data Hiding using Combined Data Hiding TechniquesIRJET Journal
This document presents a method for securing high capacity data hiding using combined data hiding techniques. The method encrypts a message using transposition cipher cryptography, applies a password, and then hides the encrypted message in an image using least significant bit steganography. Experimental results on hiding messages in various images found peak signal-to-noise ratios remained above 30 decibels, indicating hidden data did not noticeably degrade image quality. Statistical analysis of image parameters before and after hiding data also showed little difference, making the hidden message difficult to detect. The combination of encryption, password protection, and steganography provides three layers of security to better protect sizable messages.
Genetic Algorithm based Mosaic Image Steganography for Enhanced SecurityIDES Editor
The document summarizes previous work on mosaic image steganography and proposes using genetic algorithms and key-based random permutation to improve the technique. Mosaic image steganography hides a secret image by dividing it into fragments and embedding the fragments into a target image to create a mosaic. Previous methods required a large database of images or allowed only arbitrary target image selection. The proposed method uses genetic algorithms to generate a mapping sequence for embedding tile images without a database, improving clarity and reducing computational complexity. It also applies a key-based random permutation to the mapping sequence for enhanced security and robustness. The mosaic image can be recovered using the same key and mapping sequence, making it a lossless data hiding method.

In the present scenario the use of images increased extremely in the cyber world so that we can
easily transfer data with the help of these images in a secured way. Image steganography becomes
important in this manner. Steganography and cryptography are the two techniques that are often confused
with each other. The input and output of steganography looks alike, but for cryptography the output will be
in an encrypted form which always draws attraction to the attacker. This paper combines both
steganography and cryptography so that attacker doesn’t know about the existence of message and the
message itself is encrypted to ensure more security. The textual data entered by the user is encrypted using
AES algorithm. After encryption, the encrypted data is stored in the colour image by using a hash based
algorithm. Most of the steganographic algorithms available today is suitable for a specific image format
and these algorithms suffers from poor quality of the embedded image. The proposed work does not corrupt
the images quality in any form. The striking feature is that this algorithm is suitable for almost all image
formats e.g.: jpeg/jpg, Bitmap, TIFF and GIFF.

The document concludes that steganography can help protect messages not only from intruders but also from server-side attacks by making it difficult for the server to detect and decrypt embedded messages.
This document proposes an improved steganography approach using color-guided channels in digital images. It begins with an introduction to steganography and discusses how it can be used to hide secret data or messages within cover objects like images, video, or audio files.

The data is then embedded directly into the LSBs of some channels and indirectly into other channels by encoding counts. This approach aims to improve the visual quality of the stego image and have higher embedding capacity compared to existing methods.
This document summarizes a student project on implementing steganography for daily communication. It discusses using a least significant bit (LSB) approach to embed text into an image covertly.

STUDY THE EFFECT OF RESPONSE REDUCTION FACTOR ON RC FRAMED STRUCTUREIRJET Journal
This study examines the effect of response reduction factors (R factors) on reinforced concrete (RC) framed structures through nonlinear dynamic analysis. Three RC frame models with varying heights (4, 8, and 12 stories) were analyzed in ETABS software under different R factors ranging from 1 to 5. The results showed that displacement increased as the R factor decreased, indicating less linear behavior for lower R factors. Drift also decreased proportionally with increasing R factors from 1 to 5. Shear forces in the frames decreased with higher R factors. In general, R factors of 3 to 5 produced more satisfactory performance with less displacement and drift. The displacement variations between different building heights were consistent at different R factors. This study evaluated how R factors influence

STUDY THE EFFECT OF RESPONSE REDUCTION FACTOR ON RC FRAMED STRUCTUREIRJET Journal
This study examines the effect of response reduction factors (R factors) on reinforced concrete (RC) framed structures through nonlinear dynamic analysis. Three RC frame models with varying heights (4, 8, and 12 stories) were analyzed in ETABS software under different R factors ranging from 1 to 5. The results showed that displacement increased as the R factor decreased, indicating less linear behavior for lower R factors. Drift also decreased proportionally with increasing R factors from 1 to 5. Shear forces in the frames decreased with higher R factors. In general, R factors of 3 to 5 produced more satisfactory performance with less displacement and drift. The displacement variations between different building heights were consistent at different R factors. This study evaluated how R factors influence
