Artifacts Removal of Compressed Digital Images by Linear Enhancement and Filtering

Digital images that are compressed by JPEG compression schemes are affected by compression artifacts. The blocking artifacts and the ringing artifacts are the commonly seen compression artifacts. These artifacts need to be removed when we decompress the image for various applications. The objective of this work is to remove these artifacts without degrading the image. These compression artifacts can be reduced by low pass filtering of compressed mages. Low pass filtering of images cause loss of information whereby the images get blurred or the clarity of images get reduced. In this work, compressed image is first enhanced using linear enhancement technique and the resulting enhanced image is filtered using Gaussian type filter. The enhanced artifacts are removed more effectively when filtering is done in the enhanced image domain. After the removal of compression artifacts the linear enhancement is removed by the inverse of the transform which is used for linearly enhancing the image. After the removal of artifacts images will be of good quality which can be used in application areas like analysis medical image, analysis of satellite image, remote sensing and product inspection in industry.
On the possibility of secure program obfuscation in some model of cloud computing

In this paper we study the possibility of using a certain cloud computing model supplied with cryptoservers to obfuscate software programs. Earlier, we proposed this cloud computing model in our study of some information security problems for multi-client distributed computing over encrypted data. Based on this model, we proposed a new approach involving the use of threshold homomorphic cryptosystems for program obfuscation. The main result of this paper is a new definition of the resistance of obfuscation of programs in the cloud computing model and a theorem proving the cryptographic strength of the proposed algorithm of obfuscation of programs under the assumption of the existence of cryptographically strong threshold homomorphic encryption systems. The paper is organized as follows. In the introducing section we discuss the main aspects of the information security problems for cloud computing systems. Section 2 provides a description of the obfuscation program objectives, as well as a brief overview of the main achievements in its study. The next section provides general information about homomorphic cryptosystems. Section 4 describes a more special class of homomorphic cryptosystems - threshold homomorphic encryption systems. Section 5 introduces the cloud computing model, which is used as framework for our program obfuscation techniques. For this computing environment, in Section 6, the definition of the cryptographic strength of program obfuscation is formulated, a new method of program obfuscation using threshold homomorphic cryptosystems is described, and the cryptographic strength of the proposed obfuscation algorithm is proved.
Information Security

Information is now more accessible than ever before. Before the advent of electronic media, we stored and shared information mainly on paper media. For example, knowledge was exclusively shared by means of books and newspapers. People bought these or borrowed them from a library. Even further back, communication media consisted of sending letters and telegrams. In those days, if you wanted to secure some information, you would physically lock it up in a secret storage location, such as a locked cupboard or a safe. Secure messaging could be done by using a trusted courier, who would not share the information with anyone else and would share it only with the correct recipient.

Trusted and Protection of Exemplary Eventualities of Threats against Privileged Data Secrets across Sleepwake Cycles in Personal Computers

Our paper notices that with a high probability the computer faced with physical attacks can be in a suspended mode. We have more interest in addressing a series of existing and plausible threats to cyber security where the opponent possesses unconventional attack capabilities. Such unconventionality includes, in our exploration t but not restricted to, crowd sourcing, physical coercion, substantial machine resources, malicious insiders, etc. Throughout this paper, we have a tendency to tend to demonstrate but our philosophy is applied to affect several exemplary eventualities of unconventional threats, and elaborate on the model systems data secrets across sleepwake cycles. Most PCs, particularly laptops, remain in rest suspend to RAM, when not in dynamic use. A vital inspect for unattended PCs in rest is that the nearness of client insider facts in framework memory. An aggressor with material approach of a computer in rest will launch side vein memory attacks, by handling liable device drivers; regular mitigations include like bugs etc. A sophisticated assailant can likewise fall back on chilly boot assaults by handling DRAM memory impact. Hypnoguard2 protects in RAM information once a laptop is in sleep simply just in case of assorted memory attacks ecosystem for every desktop and mobile platforms, the appliance of reliable computing still remains rare or exclusively by certain manufacturers. In reality, a way larger issue is that the inspiration of trust is sometimes a combination, this becomes a significant barrier for the tutorial analysis due to lack of access to hardware primitives or public documentation. We believe the high level methodology of these research topics can contribute to advancing the security research under strong adversarial assumptions, and the promotion of software hardware orchestration in protecting execution integrity therein.
Visual Cryptography

Performability modelling and analysis of server virtualised systems subject to workload-dependent software aging

This paper tackles performability modelling and analysis of versatile server virtualised systems subject to workload-dependent software aging, failures and rejuvenation. We develop a modular modelling approach based on stochastic reward nets to investigate dependencies between several server virtualised system modules including virtual machine monitor, virtual machine, data intensive applications and workload-aware power management mechanism. Two case studies are considered, each of them accounts for a specific virtual machine monitor rejuvenation technique (Cold-VM or Migrate-VM). We show through numerical analysis how steady-state availability and power-performance metric are impacted by workload-dependent software aging and workload burstiness.
8. Designs

This chapter discusses designs law, which is a collection of legal rights that can protect designers of products from having the appearance or shape of their products copied, or give them a monopoly over the commercial exploitation of a shape. Designs law is not about any literary or musical content recorded on a product—that will be protected by copyright. Similarly, the underlying technological ideas may be protected by a patent. In the UK, copyright in designs cannot be used to prevent designs for everyday, functional articles from being copied; only artistic designs can be protected by copyright. Design right protects non-artistic designs and registered designs, and protects designs which are new and of individual character by a monopoly right that lasts 25 years. Registered designs law has been harmonized by the European Union.

Design of Image Steganography using M-BAT Optimization

This paper devotes itself to the study of secret message delivery using the cover image and introduces a novel steganography technique based on bat algorithm. To maintain the same quality even after extraction of the image at the receiving end of the system, we used a data encryption standard approach integrated with wavelet transform for preserving high security. Also to increase the embed capacity modified BAT technique is used that results in high PSNR and low MSE values. With the help of modifications to exploitation, swarm initialization and Torus gives rise to (M-BAT) for fast convergence rate. All the simulations are carried with Matlab 2017a and its evaluation parameters are related with other traditional techniques.

CAN TAILORING SKILLS BE DELIVERED THROUGH E-LEARNING PLATFORM; PERSPECTIVE OF THE THREE-LEARNING DOMAINS (COGNITIVE, AFFECTIVE AND PSYCHOMOTOR DOMAIN)

E-learning is a process of learning where we use the electronic-based platform through the internet. Nowadays, e-learning has become very essential for academia and vocational skills training through the use of the internet. During the ongoing lockdown, the Ministry of Education of Bangladesh is conducting online classes through various e-learning platforms. Education activities have been completed through e-learning but technical education is lagging in Bangladesh in the new-norm situation. With this backdrop, the study has developed a model for teaching tailoring curriculum to train the tailors' course to participants in selected areas of Bangladesh. The approach of this research is classroom action research in e-platform involving teachers to examine common issues. Teachers have followed the three learning domains (Cognitive, affective &amp; psychomotor domains) to make the students skilled in tailoring via e-platform. The study will show how the new teaching method was applied using e-platform and the impact of the proposed teaching method in the gradual improvement of the psychomotor skill in the tailoring of the students. This study implies the NSD program of the Ministry of Education. It is expected that the study will help to improve psychomotor skills by a proposed teaching system using an e-platform in the new-norm situation.

Creating web signature for each individual user and its various applications

In this paper we describe our experiments and their results to generate unique web signatures for students and study its relationships with their time spent on internet, academic performance and participating in curricular activities. Further, we demonstrate the usage of this web signature to identify outliers in student community based on their different behavioural dimensions. Our results contradict widely held perception that access and usage of internet have adverse effects on academic performance. It seems to contribute positively in academic performance. The major applications of web signature are: 1) to help administrators to predict the more overloaded timing per day and plan for that; 2) to group users based on their similarity of contents of behaviours and establishing social network between those users. Main benefits for creating this social network are to help to fresher students for connecting to professional and expert people and discuss problems or difficulties.
A novel dyadic multiresolution wavelet image steganography using N-ary

Steganography plays an important role in information sharing. In this paper a wavelet based image steganography using Haar wavelet and an N-ary notation is proposed. The high and middle frequency coefficients are selected based on the Shannon entropy value to identify the best sub band for data hiding. Peak signal to noise ratio and Structure similarity index metric values are computed from the stego image. The empirical results show the proposed method provides good, better imperceptibility and data capacity with average peak signal to noise ratio 53.60 dB for 359,112 bits in terms of effectiveness. To prove this accomplishment of the method, several experiments were conducted and compared the results with existing works.

Hierarchical Tensor Representation

The hierarchical tensor representation (notation: Hr) allows to keep the advantages of the subspace structure of the tensor subspace format Tr, but has only linear cost with respect to the order d concerning storage and operations. The hierarchy mentioned in the name is given by a ‘dimension partition tree’. The fact that the tree is binary, allows a simple application of the singular-value decomposition and enables an easy truncation procedure. After an introduction in Section 11.1, the algebraic structure of the hierarchical tensor representation is described in Section 11.2. While the algebraic representation uses subspaces, the concrete representation in Section 11.3 introduces frames or bases and the associated coefficient matrices in the hierarchy. Again, higher order singular-value decompositions (HOSVD) can be applied and the left singular vectors can be used as basis. In Section 11.4, the approximation in the Hr format is studied with respect to two aspects. First, the best approximation within Hr can be considered. Second, the HOSVD bases allow a quasi-optimal truncation. Section 11.5 discusses the joining of two representations. This important feature is needed if two tensors described by two different hierarchical tensor representations require a common representation.
Hash Tables Considered Harmful

Many system administrators would agree that, had it not been for access points, the study of evolutionary programming might never have oc-curred. In this paper, we disconfirm the analysis of the Internet, which embodies the significant principles of machine learning. We introduce an analysis of flip-flop gates, which we call Wyd-Humorism.

Rasterhadoop: An Application Perspective of Raster Data Processing on Hadoop

Hadoop is currently the most popular platform for parallel processing. With its two major components namely the Distributed File System (HDFS) and a parallel processing paradigm (MapReduce) in addition to its ease of installation and usage, Hadoop has become the chosen platform for efficiency whether in the commercial arena or the scientific arena such as Satellite Data Processing. The number of remote sensing satellites have also grown leaps and bounds and the data sent back by them for processing has all the three characteristics namely volume, velocity and variety that make it Big Spatial Data. In this paper, we present the extensions provided to Hadoop that enable Image Processing using legacy code and further elaborate on the various methods provided.
Collecting and Analyzing Academic Publication with UTeMAIR

Academic publication has been one of the main requirements in academic research and university ranking to seek research funding and scholarship. Mostly, the publication is published as academic journal article, book or thesis in offline and online distribution. There are variety of tools and services available today to understand academic publication data. However, existing tools is still very limited in the terms of specific institute and academics. In this study, we propose a practical tool, UTeMAIR which retrieve publication information for academic staff of specific institute from online publication repositories sites such as Google Scholar and Scopus. Specifically, UTeMAIR consists of three main components namely, crawling engine, statistical analysis and keywords analysis. The objectives of this system to retrieve and store publication record of academic staff, to continuously update the collected information and to analyze publication data for all academic staff. With the availability of an effective retrieval and analysis tool for publication data, the university can monitor scholarly information in a better way and plan towards increasing the publication index among academics and ultimately improve university visibility.
