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.

separable reversible data hiding in encrypted imageZTech Proje
This document proposes a method for separable reversible data hiding in encrypted images. The method uses different keys for image encryption and data hiding, allowing the data and original image to be retrieved independently. This improves on existing systems that use the same key for encryption and data hiding, allowing anyone with the key to access both the hidden data and original image. The proposed method encrypts images with an encryption key, then hides data in the encrypted images with a separate data hiding key. Receivers with the data hiding key can retrieve the hidden data, and receivers with the encryption key can retrieve the original image, without extracting the hidden data.
Scalable Image Encryption Based Lossless Image CompressionIJERA Editor
Present days processing of the image compression is the main protective representation with considerable data
process on each image progression. Traditionally more number of techniques were introduced for during
efficient progression in image compression on the data set representation process of application development. A
content owner encrypts the original uncompressed image using an encryption key. Then, a data hider may
compress the least significant bits of the encrypted image using a data hiding key to create a sparse space to
accommodate some additional data. With an encrypted image containing additional data, if a receiver has the
data hiding key, receiver can extract the additional data though receiver does not know the image content. If the
receiver has the encryption key, can decrypt the received data to obtain an image similar to the original one. If
the receiver has both the data hiding key and the encryption key, can extract the additional data and recover the
original content.\
The protection of multimedia data is becoming very
important. The protection of this multimedia data can be done
with encryption or data hiding algorithms. To decrease

Reversible data hiding in encrypted images by reserving room before encryptionIEEEFINALYEARPROJECTS
The document proposes a novel reversible data hiding method called "reserving room before encryption" (RRBE). It reserves room in the original image prior to encryption using a traditional reversible data hiding algorithm. This allows easy embedding of data in the encrypted image without errors during extraction and recovery. Experiments show it can embed over 10 times more payload than previous methods like vacating room from encrypted images, for the same image quality. The key advantages are real reversibility without extraction or recovery errors, and improved image quality for a given payload or increased payload for acceptable quality.

International Journal of Computational Engineering Research (IJCER) is dedicated to protecting personal information and will make every reasonable effort to handle collected information appropriately. All information collected, as well as related requests, will be handled as carefully and efficiently as possible in accordance with IJCER standards for integrity and objectivity.
This document proposes a method called learnable image encryption that allows deep learning to be performed on encrypted images while protecting privacy. It works by applying weak block-wise encryption to images before training deep learning models. The models can still learn meaningful patterns from the encrypted images. This approach could help shopping malls analyze customer behavior from security camera footage or allow companies to develop AI systems using encrypted data without compromising privacy. The method achieves comparable accuracy to training on plain images while keeping the encrypted images unintelligible to humans. Code and details on the block-wise encryption and decryption algorithms are available online.
The document discusses hiding confidential text data within an encrypted image using reversible data hiding techniques. It begins by introducing the concepts of reversible data hiding and meaningful image encryption. The proposed method first encrypts an original image using AES to create a pre-encrypted image. It then applies discrete wavelet transform to the pre-encrypted image to transform it into a visually meaningful encrypted image. Finally, reversible data hiding is used to hide confidential text data within the meaningful encrypted image while still allowing lossless retrieval of both the image and hidden data. The method aims to provide effective data protection with low computational cost.
The document summarizes key-aggregate cryptosystem (KAC), which allows efficient and flexible sharing of encrypted
data in cloud storage. KAC encrypts data under a public key and ciphertext class. The key owner can generate an
aggregate decryption key that decrypts any ciphertext whose class is contained in the key, while keeping a constant size.
This compact aggregate key can be shared to delegate decryption rights for a set of ciphertexts, without sharing individual
keys. KAC schemes aim to achieve constant-size ciphertexts, public keys, master secrets and aggregate keys to enable
flexible and efficient data sharing in cloud storage.
The document proposes a technique for securing data by hiding it within an image using reversible data hiding and additional encryption. Specifically:
1) Data is first hidden in an image using reversible data hiding to create a watermarked image.
2) The watermarked image is then encrypted using an elliptic curve cryptography (ECC) algorithm.
3) To provide an additional layer of security, the encrypted image is then converted to text format before transmission. This makes it difficult for hackers to determine if the transmitted data is an image or text.
4) At the receiving end, the text can be decrypted back into an image to extract the hidden data, while still allowing recovery of the original image without any loss or

Secured Reversible Data Hiding In Encrypted Images Using Hyper ChaosCSCJournals
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. Here a novel method is proposed by reserving room before encryption with a traditional RDH algorithm, and thus it is easy for the data hider to reversibly embed data in the encrypted image. Moreover data to be embedded is shuffled using a hyper chaotic function which is difficult to be extracted from the stego image without original key. A digital water mark is also embedded which ensures integrity of the data. The proposed method has been validated against three other available RDH schemes and it is observed that the proposed scheme outperforms these RDH schemes both in visual quality and payload. The proposed method can achieve real reversibility, that is, data extraction and image recovery are free of any error.
Secure Data Sharing Using Compact Summation key in Hybrid Cloud StorageIOSR Journals
This document proposes a new encryption scheme called compact summation key encryption for secure data sharing in hybrid cloud storage. It aims to address limitations of existing approaches like predefined hierarchical schemes, attribute-based encryption, and identity-based encryption which cannot provide security to individual files or have non-constant size keys. The new scheme uses five algorithms: setup, key generation, encryption, extraction and decryption. It generates constant size public and master secret keys. Encryption uses file indexes and bilinear groups to create ciphertexts. Extraction combines decryption keys into a single compact summation key using bilinear pairing operations. This key can then decrypt ciphertexts for multiple file indexes, improving flexibility and efficiency of secure data sharing in cloud storage.
The document discusses combining cryptography and steganography techniques for secure communication. It proposes encrypting a message before hiding it in a digital object like an image file. This provides two layers of security since an extracted hidden message would still be encrypted. The document outlines the cryptography and steganography algorithms to be used, including AES encryption and least significant bit steganography with improvements like randomization and hashing.
1) The document proposes using spread spectrum image steganography (SSIS) to securely store data in the cloud by hiding data within digital images. SSIS spreads a message across a digital image as low-power noise to make the hidden data imperceptible.
2) When a user uploads data to the cloud, SSIS software would encrypt the data multiple times within an image. Even if hackers access the encrypted image, they cannot decrypt the data without knowing how many times the user encrypted it.
3) This provides double security by encrypting data within an image format and ensuring hackers cannot decrypt without the encryption key information known only to the authorized user.
Why Encryption For The Cloud Is A Good Ideaarbingersys
The cloud refers to using computers owned by others over the internet to process and store data remotely. While a user's data is usually safe in the cloud, it is not completely private as data breaches or weaknesses in a provider's security policies could expose it. However, encrypting data makes it unviewable by anyone without the encryption key, allowing private data to safely exist in the cloud.
DATA HIDING IN ENCRYPTED H.264 VIDEO FORMATalphin jose
I-frames, P-frames, and B-frames are the three major picture types or frame types used in video compression algorithms. I-frames are fully specified frames that do not require other frames to decode but are the least compressible. P-frames store only the changes from previous frames and are more compressible than I-frames but require previous frames to decode. B-frames can use both previous and forward frames for reference and achieve the highest compression but require both previous and forward frames to decode. I-frames are used as random access points and references for decoding other frames.
The document proposes a chaotic image encryption technique using Henon chaotic systems. It consists of two main steps: 1) Image fusion between the original image and a key image. 2) Encrypting the pixel values of the fused image using a Henon chaotic map. The technique aims to provide high security with less computational time compared to traditional encryption methods. Experimental results show the algorithm is sensitive to keys and resistant to brute force attacks. The technique can be used for applications like secure internet image transmission.
Machine Learning (ML) algorithms are gaining momentum as main components in a large number of fields, from computer vision and robotics to finance and biotechnology. However, many challenges need to be solved when Artificial Intelligence is applied to different settings, such as cloud computing or embedded systems. At the same time, the use of Field Programmable Gate Arrays (FPGAs) for data-intensive applications is increasingly widespread thanks to the possibility to customize hardware accelerators and achieve high-performance implementations with low energy consumption. This presentation is an overview of the ongoing ML-based projects that are developing at NECSTLab, the laboratory of hardware architectures and computer security of Politecnico di Milano.

Reversible Data Hiding In Encrypted Images And Its Application To Secure Miss...CSCJournals
This paper proposes reversible data hiding in encrypted images for secure missile launching. The work is presented in two stages: one involves encryption of cover image by block cipher algorithm and other is embedding secure data related to missile launching. For embedding data, vacant pixels are identified by Slepian-Wolf encoding method along with embedding key to hide the data. At the other end by using decryption algorithm the original cover image is recovered and the secret data is extracted. The performance analysis is presented by calculating parameters MSE, PSNR and SSIM.
novel Approach For Data Hiding by integrating Steganography and Extended Visu...swapnalithakur7
This document proposes a system that combines visual cryptography and steganography to provide multiple levels of security. It aims to overcome the limitations of single-level hiding approaches. The proposed system first encrypts a secret message using RSA encryption and then hides the cipher text in an image using steganography. This stego image is transmitted along with a cover video. The receiver extracts the stego image from the video and decrypts the cipher text using their private key to retrieve the original secret message. The system implements visual cryptography to allow decryption through human vision without requiring any computation.
Decrypt and Encrypt the Image in Cryptographic Algorithm HS Based RDH and LSB...IRJET Journal
This document discusses methods for encrypting and decrypting images using reversible data hiding and least significant bit algorithms with asymmetric cryptography. It proposes a method that reserves room in the image before encryption using histogram shift-based reversible data hiding and least significant bit algorithms with a public key cryptosystem. This allows data to be embedded in the encrypted image simply for the user. The embedded data and original image can then be extracted and recovered later without any loss of pixels or data. The method claims to embed more than ten times as much data as other techniques while maintaining image quality and restoration after encryption.
This document discusses separable reversible data hiding using matrix addition for color images. It proposes a scheme where the content owner encrypts the original image, then a data hider embeds additional data using a data hiding key. The receiver can extract the hidden data and recover the original image by separately providing the encryption key and data hiding key. Lossy and lossless compression techniques for images are also discussed. Reversible data hiding allows exact recovery of the original image and extraction of hidden data without errors when the amount of additional data is large.
Data encryption using LSB matching algorithm and Reserving Room before Encryp...IJERA Editor
Now a days, 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. Previously proposed methods embed data by
reversibly vacating room from the encrypted images, which may cause some errors in data during data extraction
and/or image restoration. In this paper, a novel method of reserving room before encryption with a traditional
RDH algorithm, and thus it is easy for the data hider to reversibly embed data in the encrypted image is
proposed. The proposed method can achieve real reversibility, that is, data extraction and image recovery are
free of any error.
This document proposes a novel reversible data hiding method called "Reserving Room Before Encryption" (RRBE) for color images. The key steps are: (1) Reserve space in the cover image by embedding pixel LSBs before encryption using an LSB plane method. (2) Encrypt the cover image. (3) Data can then be hidden in the reserved spaces of the encrypted image. (4) Data extraction and image recovery are possible without error since space was reserved before encryption, separating these processes from decryption. Using color images provides more data hiding capacity across the three channels. The method allows for reversible data hiding in encrypted images without the errors introduced by previous techniques that vacate space after encryption.

Securing Image Steganogarphy Based on Visual Cryptography And Integer Wavelet...IOSR Journals
The document proposes a new method for securing image steganography using visual cryptography and integer wavelet transform. The method embeds a secret image into a cover image in the following steps: 1) Apply (2 out of 2) visual cryptography to the secret image to generate two secret shares. 2) Apply a two-level integer wavelet transform to the blue channel of the cover image, resulting in four sub-bands. 3) Embed each secret share into one of the four sub-bands. 4) Combine the channels to generate the stego-image. Extraction requires applying the same transforms to the stego-image to recover the secret shares and reconstruct the secret image, without needing the original cover image. The method
This document summarizes a research paper that proposes a novel reversible data hiding scheme using AES encryption. The scheme consists of three phases: 1) AES encryption of the original image, 2) data embedding by modifying parts of the encrypted image, 3) data extraction and image recovery by decrypting the encrypted image and extracting the hidden data. The scheme aims to securely hide data in images while allowing perfect recovery of the original image. Experimental results show the decrypted image has a high PSNR value of 55.11dB and the hidden data can be successfully extracted.
In recent years the topic of steganography has become
very popular and a lot of research is being done in this field.
Reversible data hiding is a method in which the image in which
the encrypted data is hidden is losslessly recovered. In this paper
we have proposed such a method that the previous work done
limitations can be overcome. In this paper, we embed the
encrypted data in the image by using LSB matching technique for
reserving room, so that fast, optimal and lossless steganography
is achieved. The proposed method provides total reversibility,
that is, data extraction and image recovery.

Cloud computing is a powerful, flexible, cost
efficient platform for providing consumer IT services
over the Internet. However Cloud Computing has
various level of risk because most important
information is maintained and managed by third party
vendors, which means harder to maintain security for
user’s data .Steganography is one of the ways to provide
security for secret data by inserting in an image or
video. In this most of the algorithms are based on the
Least Significant Bit (LSB), but the hackers easily
detects it embeds directly. An Efficient and secure
method of embedding secret message-extracting
message into or from color image using Artificial
Neural Network will be proposed. The proposed
method will be tested, implemented and analyzed for
various color images of different sizes and different
sizes of secret messages. The performance of the
algorithm will be analyzed by calculating various
parameters like PSNR, MSE and the results are good
compared to existing algorithms.

This document discusses message transfer using steganography. Steganography is used to hide information like text, images or videos within other media files such as images, videos or music. The document discusses how steganography can be used to securely transfer messages between two parties by hiding the messages within digital files like images without the server being able to decrypt the messages. It discusses how the least significant bits of pixels can be modified to embed secret data without significantly affecting the cover image. Different encryption techniques for embedding the data are also discussed. 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.
11.biometric data security using recursive visual cryptographyAlexander Decker
This document summarizes a research paper on using recursive visual cryptography and biometric authentication to securely store biometric data. The paper proposes a scheme where secrets can be recursively embedded within image shares created by visual cryptography. Additionally, biometric authentication is used to securely access the shares. The scheme involves creating shares of secrets, embedding those shares as additional secrets within other shares, and authenticating users through iris recognition before revealing embedded secrets. This allows for multiple secrets to be hidden and revealed securely through the visual cryptography and biometric authentication methods combined.
Designing an efficient image encryption then-compression system via predictio...LeMeniz Infotech
The document proposes a new image encryption-then-compression system that aims to efficiently compress encrypted images while maintaining a high level of security. It suggests encrypting images in the prediction error domain and using context-adaptive arithmetic coding to compress the encrypted data, resulting in only a negligible loss in compression efficiency compared to compressing the original images. This approach improves upon existing systems that induce significant penalties on compression performance when encrypting images prior to compression.

This document discusses energy-efficient strategies for cooperative multichannel MAC protocols. It introduces Distributed Information SHaring (DISH), which helps nodes make decisions by sharing information with neighboring nodes. This approach was shown to significantly increase throughput but had not addressed energy efficiency. The paper proposes two strategies: in-situ energy conscious DISH which uses existing nodes, and altruistic DISH which uses additional nodes called altruists. Evaluation shows altruistic DISH conserves 40-80% of energy, maintains throughput advantages, and more than doubles cost efficiency compared to protocols without this strategy. In-situ energy conscious DISH is only suitable in limited scenarios.

The document presents a new approach called TSCAN for temporally summarizing topics from a collection of documents. TSCAN first derives the major themes of a topic from the eigenvectors of a temporal block association matrix. It then extracts significant events and their summaries for each theme by examining the eigenvectors. Finally, it associates the extracted events based on their temporal closeness and context similarity to form an evolution graph of the topic. Experiments on the TDT4 corpus show that temporal summaries generated by TSCAN present topics in a comprehensible form and are superior to existing summarization methods based on human references.

Separable Reversible Data Hiding in Encrypted Image
Abstract
1
This work proposes a novel scheme for separable reversible data hiding in
encrypted images. In the first phase, a content owner encrypts the original uncompressed
image using an encryption key. Then, a data-hider may compress the least significant bits
of the encrypted image using a data-hiding key to create a sparse space to accommodate
some additional data. With an encrypted image containing additional data, if a receiver
has the data-hiding key, he can extract the additional data though he does not know the
image content. If the receiver has the encryption key, he can decrypt the received data to
obtain an image similar to the original one, but cannot extract the additional data. If the
receiver has both the data-hiding key and the encryption key, he can extract the additional
data and recover the original content without any error by exploiting the spatial
correlation in natural image when the amount of additional data is not too large.
