Abstract:

The paper proposes two information hiding algorithms for multimedia based on Quantization Index Modulation (QIM): IM-QIM and SIM-QIM. They are designed to prevent a statistical attack which is able to restore a secret key using the correlation between key bits and multimedia data samples. To obtain the required security, we use a correlation immune embedding function, which guarantees statistical independence between the watermarked data and the key. The proposed algorithms are described for the case of spatial embedding in images but the algorithms can also be used to hide information in any multimedia data source in spatio-temporal and spectral domains. The results of the experimental investigation have confirmed that the algorithms developed provide the required security against a statistical attack and also have shown that the algorithms do not introduce additional distortions compared with the conventional QIM method. However, the experiments have also shown that the new algorithms are less robust against additive noise and JPEG compression.

Abstract In this paper a new method for information hiding in open social networks is introduced. The method, called StegHash, is based on the use of hashtags in various open social networks to connect multimedia files (like images, movies, songs) with embedded hidden messages. The evaluation of the system was performed on two social media services (Twitter and Instagram) with a simple environment as a proof of concept. The experiments proved that the initial idea was correct, thus the proposed system could create a completely new area of threats in social networks.

Full text

Abstract:

Bit-plane complexity segmentation (BPCS) steganography is advantageous in its capacity and imperceptibility. The important step of BPCS steganography is how to locate noisy regions in a cover image exactly. The regular method, black-and-white border complexity, is a simple and easy way, but it is not always useful, especially for periodical patterns. Run-length irregularity and border noisiness are introduced in this paper to work out this problem. Canonical Cray coding (CGC) is also used to replace pure binary coding (PBC), because CGC makes use of characteristic of human vision system. Conjugation operation is applied to convert simple blocks into complex ones. In order to contradict BPCS steganalysis, improved BPCS steganography algorithm adopted different bit-planes with different complexity. The higher the bit-plane is, the smaller the complexity is. It is proven that the improved BPCS steganography is superior to BPCS steganography by experiment.

Abstract:

This paper aims to find an effective and efficient information hiding method used for protecting secret information by embedding it in a cover media such as images. Finding the optimal set of the image pixel bits to be substituted by the secret message bits, such that the cover image is of high quality, is a complex process and there is an exponential number of feasible solutions. Two new ant-based algorithms are proposed and compared with other algorithms. The experimental results show that ant colony optimization algorithm can find the solution efficiently and effectively by finding the optimal set of pixel bits in a few number of iterations and with least Mean Square Error (MSE) comparable with genetic and genetic simulated annealing algorithms.

Abstract:

In order to effectively increase embedding capacity and completely extract the watermarking information in information hiding of encrypted images, a new reversible watermarking embedding algorithm based on rhombus prediction model and difference histogram shifting ideas is proposed. Firstly, the images are pretreated according to rhombus prediction model. Then, the watermarking information is embedded in encrypted images by effective combination of homomorphism encryption scheme and reversible watermarking techniques. Finally, the watermarking information is completely extracted and the images are recovered based on computed difference histogram from left to right and from top to bottom. So, the efficiency and reversibility are ensured when watermarking information is embedded in encrypted image. Experiment results show that the proposed algorithm is simple and easy to realize, the embedding capacity is effectively increased, watermarking information is completely reversible, and the image can be recovered with no distortion.

Abstract:

Knowledge hiding is a destructive behavior that degrades organizational success. Knowledge hiding is the intentional withholding of information from another employee. It has been reported that 76% of U.S. employees hide knowledge from each other. The displaced aggression theory suggests that employees are more likely to hide knowledge from others in the presence of mistreatment by a leader. Therefore, there was a need to investigate new ethical theories that have been shown to influence organizational commitment and potentially decrease knowledge-hiding practices among employees. This research used foundational leadership theory (FLT) developed by Fuller in 2021 to examine the overall influence on knowledge hiding. The sample consisted of 306 full-time employees across various industries throughout the United States. The results indicated that FLT had a significant negative relationship (-0.64); regression analysis indicated that, as FLT increased, knowledge hiding decreased by 0.57. Therefore, leadership training programs that teach ethical leaders based on integrity, assurance, and pragmatism will likely reduce knowledge hiding tactics among employees and create a strategic advantage among competitors.

Abstract:

Commitment schemes are important tools in cryptography and used as building blocks in many cryptographic protocols. We propose two commitment schemes by using Rubik’s groups. Our proposals do not lay the security on the taken-for-granted hardness of the word problem over Rubik’s groups. Instead, our first proposal is based on a symmetric encryption algorithm that is secure based on the hardness of the conjugacy search problem over Rubik’s groups, while our second proposal is based on the hardness of a newly derived problem—the functional towering conjugacy search problem over Rubik’s groups. The former is proved secure in the sense of both computational hiding and binding, while the latter is proved even secure in the sense of perfect hiding and computational binding. Furthermore, the proposed schemes have a remarkable performance advantage: a linear commitment/opening speed. We also evaluate the efficiency of the commitment schemes and show that they are considerably fast.

Abstract:

<p class="Abstract">Data Hiding has a huge range of applications in the medical field for transmission. It is helpful in securing the documentation of the patients from the violator with good storage space. The medical images of different modalities like CT, MRI, and PET with the digitized clinical information can be sent to the doctors across the world for the treatment. Due to the bandwidth and storage constraints, medical images along with the clinical information must be compressed before transmission and storage. This paper gives a technique for hiding the digitized clinical information along with the DICOM images in Complex Contourlet Transform (CCT) Domain. It also analyses the compression method by using an Entropy Encoder method. Hence, this work suggests that the data hiding method based on Complex Contourlet Transform (CCT) is efficient and also it has a high hiding capacity. The improved value of Compression Ratio (CR), Space Saving (SS), Mean Square Error (MSE) and Peak Signal to Noise Ratio (PSNR) shows that the new method satisfies the properties of the data hiding method.</p>

Abstract:

In this era of internet development, security of information sharing is the main problem faced by human being. Data hiding technique is one of the solutions. However, hiding credential information within a multimedia file such as image reduces its visual quality. Therefore, unauthorized users may suspect the existance of secret data within that image. In the past years, various data hiding algorithms have been developed by researchers to overcome the problem of high distortion of image after data embedding process. Achieving a high quality stego image, however, is still a challenging problem. In this paper, we proposed a new data hiding algorithm based on different expansion. It aims to enhance the quality of stego image for a given payload size. The new algorithm is evaluated on various medical images. Thereafter, the experimental results show that the visual quality is improved; and increasing the embedding capacity leads to more noises. Therefore, a better choice of base point and a reduced difference expansion affect the quality of stego image.

Full text

Abstract:

This work presents a new asymmetric data hiding technique that hides a variable number of secret message bits in the discrete cosine transform (DCT) coefficients of a cover image using a modular distance technique. Prior to data hiding, the proposed framework transforms a cover image from a spatial domain to various frequency coefficients using DCT. The DCT coefficients are arranged in two groups: one with low-frequency coefficient, and the other with the medium and high-frequency coefficients. The medium and higher frequency coefficients are processed for variable data hiding asymmetrically. The proposed technique hides variable sets of secret information bits in different coefficients. The variation in hidden secret information is maintained using a key developed based on the modulo of distance of a coefficient from the reference point. The same key is also used to retrieve the confidential information at the receiver ends. The results reveal that the presented framework does not create any visually significant distortion, and thus the hidden information does not attract the human visual system (HVS). The technique also results in high data hiding efficiency.

Abstract:

This article describes how privacy preserving data mining has become one of the most important and interesting research directions in data mining. With the help of data mining techniques, people can extract hidden information and discover patterns and relationships between the data items. In most of the situations, the extracted knowledge contains sensitive information about individuals and organizations. Moreover, this sensitive information can be misused for various purposes which violate the individual's privacy. Association rules frequently predetermine significant target marketing information about a business. Significant association rules provide knowledge to the data miner as they effectively summarize the data, while uncovering any hidden relations among items that hold in the data. Association rule hiding techniques are used for protecting the knowledge extracted by the sensitive association rules during the process of association rule mining. Association rule hiding refers to the process of modifying the original database in such a way that certain sensitive association rules disappear without seriously affecting the data and the non-sensitive rules. In this article, two new hiding techniques are proposed namely hiding technique based on genetic algorithm (HGA) and dummy items creation (DIC) technique. Hiding technique based on genetic algorithm is used for hiding sensitive association rules and the dummy items creation technique hides the sensitive rules as well as it creates dummy items for the modified sensitive items. Experimental results show the performance of the proposed techniques.

Abstract:

We introduce a new type of cryptographic primitive that we call a \e{hiding fingerprinting scheme}. A (quantum) fingerprinting scheme maps a binary string of length $n$ to $d$ (qu)bits, typically $d\ll n$, such that given any string $y$ and a fingerprint of $x$, one can decide with high accuracy whether $x=y$. It can be seen that a classical fingerprint of $x$ that guarantees error $\le\eps$ necessarily reveals \asOm{\Min{n,\log(1/\eps)}} bits of information about $x$. We call a scheme \e{hiding} if it reveals \aso{\Min{n,\log(1/\eps)}} bits; accordingly, no classical scheme is hiding. }{We construct quantum hiding fingerprinting schemes. Our schemes are computationally efficient and their hiding properties are shown to be optimal.

Abstract:

Facility location is the problem of locating a public facility based on the preferences of multiple agents. In the classic framework, where each agent holds a single location on a line and can misreport it, strategyproof mechanisms for choosing the location of the facility are well-understood.We revisit this problem in a more general framework. We assume that each agent may hold several locations on the line with different degrees of importance to the agent. We study mechanisms which elicit the locations of the agents and different levels of information about their importance. Further, in addition to the classic manipulation of misreporting locations, we introduce and study a new manipulation, whereby agents may hide some of their locations. We argue for its novelty in facility location and applicability in practice. Our results provide a complete picture of the power of strategyproof mechanisms eliciting different levels of information and with respect to each type of manipulation. Surprisingly, we show that in some cases hiding locations can be a strictly more powerful manipulation than misreporting locations.

Because of the nature of PE, it is used for cloud storage so that users can retrieve encrypted data without revealing any information about the data to cloud servers and other users. Although lots of PE schemes have been studied, the predicate-hiding security is seldom considered; that is, the user’s secret key may leak sensitive information of the predicate. Additionally, the security of the current predicate-hiding PE schemes relies on the discrete logarithm assumption which cannot resist the quantum attacks in the future. In this paper, we propose a generic PE for inner product under symmetric-key setting, called private IPE, from specific key-homomorphic pseudorandom function (PRF). The rigorous proofs are provided to show that the construction is payload-hiding, attribute-hiding, and predicate-hiding secure. With the advantage of the generic construction, if the underlying PRF can resist quantum attacks, then, through our proposed generic construction, a quantum-resistant private IPE can be obtained.

In this paper, we proposed a new method for hiding and extracting information in printed chinese documents. This new method embeds information into chinese documents by varying the typefaces of chinese words. In addition, an information extracting method based on missing feature concepts is proposed to handle the partial occlusion, generated by printing and scanning operations. The new improved approach has been evaluated on numerous printed documents and demonstrated improved performance over other systems.

Abstract:

Medical image data, like most patient information, has high requirements for privacy and confidentiality. To improve the security of medical image transmission within the open network, we proposed a medical image key area protection algorithm based on reversible data hiding. First, the coefficient of variation is used to identify the key area, that is, the lesion area of the image. Then, the other regions are divided into blocks to analyze the texture complexity. Next, we propose a new reversible data hiding algorithm, which embeds the content of the key area into the high-texture regions. On this basis, a quick response (QR) code is generated using the ciphertext of the basic image information to replace the original lesion area. Experimental results show that this method can not only safely transmit sensitive patient information by hiding the content of the lesion, it can also store copyright information through QR code and achieve accurate image retrieval.

Abstract:

Information hiding in a resources section’s redundancies has large amount of watermark embedding, and the software watermarking based on PE file resources section format has high concealment. This paper combined this two algorithms’ advantages, and embedded the watermark information in these two ways. It also introduced the information hiding technology based on ICON file and binder technology to realize the tamper-proof function of the watermark. Experiments shows that this scheme not only improves the embedded information capacity, but also overcomes the problem that the embedded watermark are susceptible to tamper-proof attack. So the new scheme improves the watermark’s comprehensive performance, and create a more secure and robust software watermark.

Abstract:

Today, in the age of wireless communication, network security is an important issue. Image steganography is a popular approach to make communication secure. Among two categories (spatial domain and frequency domain) of image steganography, frequency domain is more secured than the spatial domain. The proposed scheme develops a secret communication technique in frequency domain steganography. In steganography, the concept of Laplace transformation is used during embedding and extraction procedures of secret information in image files. As a result, all the conditions of information security are developed in high density. The efficiency and effectiveness of the scheme is evaluated by measuring the hacking chance from different statistical attacks by RS steganalysis and originality of actual cover image after inserting secret information by Mean Squared Error (MSE) and Peak Signal to Noise Ratio (PSNR).

Abstract:

<p><span>Information Hiding is a task that face difficult challenges in current time. <br /> The reason for these challenges is the rapid development of methods of detection of hidden information. So, researchers have been interested in developing methods of concealment, making it difficult for attackers to access hidden information using new methods of concealment. Such as the introducing a complex algorithms, use a random methods and invent more complicated and difficult steps. This paper presents a new method of hiding information within the image. This method creates a new sequence of mysterious and difficult steps by dividing the secret text on all image and random distributing of bits to each row. Then using a special reverse method to hide the bits in that row. The LSB method has also been developed to make it more difficult to hide the pixel. The results presented illustrate the strength and security of the method and provide greater protection for hidden information. Also, the result illustrate the quality of the stego image compared with the original image using PSNR and SSIM quality measures.</span></p>

Abstract:

This paper proposes a new technique for hiding secret messages in ordinary English text. The proposed technique exploits the redundancies existing in some English language constructs. Redundancies result from the flexibility in maneuvering certain statement constituents without altering the statement meaning or correctness. For example, one can say “she went to sleep, because she was tired” or “Because she was tired, she went to sleep.” The paper provides a number of such transformations that can be applied concurrently, while keeping the overall meaning and grammar intact. The proposed data hiding technique is blind since the receiver does not keep a copy of the original uncoded text (cover). Moreover, it can hide more than three bits per statement, which is higher than that achieved in the prior work. A secret key that is a function of the various transformations used is proposed to protect the confidentiality of the hidden message. Our security analysis shows that even if the attacker knows how the transforms are employed, the secret key provides enough security to protect the confidentiality of the hidden message. Moreover, we show that the proposed transformations do not affect the inconspicuousness of the transformed statements, and thus unlikely to draw suspicion.

Abstract:

Based on human visual gray sensitivity, a fragile large capacity spatial domain information hiding algorithm, and a new calculation formula of image peak signal-to-noise ratio were put forward. An adaptive embedding method was proposed, which had the minimum visual gray sensitivity when massive information were hidden into an original image. Experiments showed that this algorithm had massive amount of embedded information and excellent masking properties, and what’s more, once there is a bit tampered randomly, the watermarking image could not be recovered correctly. So it was suitable for the situation where the received information must be very strict reliably.

Abstract:

Data hiding is emerging as an important area of research with the advent of digital technologies. Watermarking, fingerprinting and steganography are important applications of data hiding techniques. Besides the classical use of data hiding in ownership protection, authentication and copy/access control, it serves as a general tool to convey side information. New files are a good choice for steganographic carriers. In this paper, the authors use Microsoft Excel as a cover file. A methodology has been developed that consists of three techniques for embedding the valuable data with three layers of security and high robustness. The resultant stego Excel file can be transmitted anywhere using any channel. Experimental results show the feasibility of the proposed methodology.

Abstract:

In today’s electronic era, wealth of electronic information are accessing over the Internet. Several important information and private data transferring over the Internet are being hacked by attackers via latest communication technology. So, maintaining the security of secret data has been a great challenge. To tackle the security problem, cryptographic methods as well as steganographic techniques are essential. This paper focuses on hybrid security system using cryptographic algorithm and text steganographic technique to achieve a more robust security system. In this work, to overcome the limited data hiding capacity, suspiciousness, and data damaging effect due to modification, of traditional steganographic techniques, a new technique for information hiding in text file is proposed. The proposed approach conceals a message, without degrading cover, by using first, second, second last, and last letter of words of the cover text. Hence, from the embedding capacity point of view, its capacity depends on the similarity of characters of the words in cover text. In addition, as further improvement for security, secret message encryption is performed using Blowfish algorithm before hiding into the innocuous cover text.

Abstract:

Data hiding techniques are very significant in the research area of information security. In this article, the authors propose a new reversible data hiding (RDH) scheme using difference expansion. At first, the original image is partitioned into 3 × 3 pixel blocks, then marked Type-one and Type-two pixels based on their coordinate values. After that, the authors find correlated pixels by computing correlation coefficients and the median of Type-one pixels. Next, secret data bits are embedded within Type-two pixels based on correlated pixels and Type-one pixels based on the stego Type-two pixels. The data extraction process successfully extracts secret data as well as recovers the cover image. The authors observed the effects of the proposed method by performing experiments on some standard cover images and found significantly better result in terms of data hiding capacity compared with existing data hiding schemes.

<p class="0abstract">One of the unexpected intelligence tactics known in World War II was to conceal the data in images that were reduced to the size of a point that was used in every text and transported in front of the enemy's eyes. In the new age, and after the expansion of Internet science and the use of the Internet worldwide, we will establish a security feature of the IOT service that will work more reliably and more effectively to deal with the Internet of Things and ensure the work of the services that the customer interacts with. A secret-key stenographic scheme that embeds four gray-scale secret size (128*128) pixel images into a size (512*512) pixel cover image in this work. Wavelet transform is the method used in this project to analyze the cover into its frequency components. In this work, combinations of steganography and cryptography were made to increase the level of safety and make the device more difficult for attackers to beat. The resulting stego-image that will be transmitted did not raise any suspicion by both objective and subjective evaluation, so the primary objective of Steganography is achieved. The proposed system was designed by using (MATLAB R2018b) and running on a Pentium-4 computer. The Internet of Things works with the encryption system for data in a synchronized manner with the technological development, and in order to maintain the stability of any Internet of things service, whether it is information signal services, visual or audio data, a remote control system, or data storage in the Internet cloud, we must focus on data preservation from internet pirates and internet system hackers.

Abstract:

In the modern digital era, the privacy of personal communication is a serious concern to all netizens. A better way to preserve privacy could be to hide the secret message inside some innocent looking digital object such as image, audio, video, etc., which is known as steganography. A new steganographic scheme using a reference image along with the cover image has been proposed in this article. It enhances the robustness and security by increasing the obscurity of the hidden message. It also employs an additional dictionary-based encoding module to increase the hiding capacity as well as security. Experiments show that bit changes in the reference image are very few and undetectable to human perception, it also evades common statistical tests. Evaluation of standard quality parameters such as MSE, PSNR, UIQI, SSIM along with chi-squared statistics based embedding probability testing has been performed. When dictionary-based encoding is applied it further improves the quality parameters.

Abstract:

Attacks on text-based CAPTCHAs are getting more sophisticated. Most existing schemes defend attacks by increasing deformation or distortion rate of words which sacrifice the friendliness of the system. In this paper, we propose a secure one time text-based CAPTCHA scheme which can effectively defend multiple attacks without decreasing the friendliness of the scheme for valid users. The core of our design is an information obfuscation scheme which determines which character image to display and which to hide in an online manner from a sequence of 62 character images which makes it more difficult to attack. Encryption method is employed for protecting display policies which control showing and hiding of information. Prototype has been implemented and the preliminary results are encouraging.

Abstract:

Image encryption is one of the most important methods of image information hiding. A new image encryption method based on some techniques and knowledge of genetic engineering for image hiding is presented in this paper. This method is implemented by using modern biological techniques as tools and biological hard problems as main security basis to fully exert the special advantages. The keys are some substances of biological materials such as restriction endonuclease, polymerase and so on, the preparation flow and the experimental conditions. The analysis demonstrates that the image encryption algorithm is feasible and highly secure. Moreover, the size of the decrypted image is the same as the original image so that it can be applied for image hiding and be transmitted via the Internet.
