Authors: Mohammed Sahab Dheyaa , Rahma Abdul Monem S.
Published: October 2023

Encryption is necessary to maintain data confidentiality and protect against outside attackers and internal administrators in the remote database (DB). However, the use of encryption makes it difficult to retrieve data from the remote database .where in traditional methods, is retrieved all data from the DB then, data are decrypted to obtain the specific data requested by the user. However, this process is time-consuming and does not maintain enough data security. In this paper, a technique was proposed to solve traditional method defects in encrypted DB systems. The proposed technique builds queries within the proxy server and retrieves only specified encrypted data from the remote DB without the requirement of retrieved all encryption data, then decrypted at the proxy site. Results showed that the proposed method took less time than conventional methods while maintaining data confidentiality.

Authors: Ahmed Ahmed Sh. , Salah Hussein A. , Jameel Jalal Q.
Published: October 2023

In life, a chaotic system has many applications in different fields, including physics, biology, communication, and cryptography. In this study, a new hyperchaotic system is introduced. This hyperchaotic system is a two-dimensional system that is based on three maps-namely, logistic, iterative chaotic, and Henon maps. The dynamics of this system are investigated using maximal Lyapunov exponents, bifurcation diagrams, phase portraits, basin of attraction, and complexity via entropy. This system shows highly complicated dynamics. On the basis of the proposed system, a new algorithm for image encryption is also introduced. Confusion and diffusion can be achieved with this algorithm, which are fundamental demands. The stochastic behavior of this system is used to reinforce the security of the encrypted image. The image is divided into four parts, each of which uses a different random key established by the proposed chaotic system. The security of this cryptosystem is validated on the basis of key security parameters and common attacks.

Authors: Shareef Omar Salah F. , Sagheer Ali Makki
Published: October 2023

One of the big issues for dynamic organizations is managing the confidential information of big data. Improving security is needed to secure exchange of confidential documents, protection against unauthorized accesses, handling changes in the permissions and roles of people and dealing with the dynamism that can happen if any person leaves or join the system. However, there are limitations in using traditional cryptographic systems and Public Key Infrastructure (PKI) concerning flexibility and manageability. In this paper, we propose a secure and verifiable access control system that implements a Certificate Authority coupled with Role-Based Access Control to provide the permissions to the user to access data. The digital certificate is certified, issued, and revoked by a central administrator; as a result, the certificate is sent based on the role of the user. The proposed scheme has been demonstrated on a big dataset. We believe that our work can be applied to organizations that rely heavily on big data.

Authors: Selman Hassan Khalil , Ali Akbas Ezaldeen
Published: October 2023

It is widely acknowledged that the current Internet of Things (IoT) ecosystem is highly fragmented. The Web of Things (WoT) aims to counter the fragmentation using the principles of Web, standardized metadata and APIs. QR i.e. "Quick Response" code is a 2D matrix code that is designed by keeping two points under consideration, i.e. it must store large amount of data as compared to 1D barcodes and it must be decoded at high speed using any handheld device like phones. QR code provides high data storage capacity, fast scanning, omnidirectional readability, and many other advantages including, error-correction (so that damaged code can also be read successfully) and different type of versions. Different varieties of QR code symbols like logo QR code, encrypted QR code, iQR Code are also available so that user can choose among them according to their need. The WoT relies exclusively on application level protocols and tools. Web protocols are a critical factor in the successful implementation of the WoT. However, one of the main issues is web latency that may significantly affect the real-time performance of IoT systems. Some pioneer open stages and models are likewise shown. The latest research results are painstakingly outlined. Moreover, numerous efficient examinations are made to give the understanding in the advancement and eventual fate of WoT. At last, we call attention to some open testing issues that will be confronted and handled by research network.

Published: October 2023

Because of the rapid development and use of the Internet as a communication media emerged to need a high level of security during data transmission and one of these ways is "Steganography". This paper reviews the Least Signification Bit steganography used for embedding a variety of related binary images in a single grayscale image rather than traditional methods of embedding information which is embedded one image in another image (cover image). First three images represent the secret images which are used for hiding from unauthorized users while other images used for making more difficult and more secret watermark. In this paper, we have merged both methods of hiding and watermark. Instead of either creating a watermark or hiding secret data in a grayscale image, we can use both of them at the same image to take advantage of both the hiding and watermark properties at the same time. The findings of the research were the results as a new watermark composed of multiple related binary images and hidden secret multiple binary images inside.

Authors: Toman Sarah Hussein
Published: October 2023

Recently, most of the web applications depend on the web services to solve the application integration problem. Web service is an intermediate software that allows the interaction between the applications written by different languages. Web Service is a client-server, modular, self-contained, and dynamic application that ensures the communication between the applications via the World Wide Web (WWW). The aim of this paper is to choice right kind of Web services at design stage of the project. Thus, we provide an overview of web services. Next, we clarify the architecture of web services. After that, we focus on the most popular kinds of web services, the Representational State Transfer (REST) and the Simple Object Access Protocol(SOAP) then explain APIs details. Finally, we address the performance evaluation of the previous works and explained the results as comparison between SOAP and REST. A recommendation to use RESTful web services has been concluded from experimental result.

In this paper, we established some mathematical methods in order to solve real zeroes of nonlinear equation for a single diode model for a PV cell without second derivatives for the function using Improved Double False Position method as called (Illinois algorithm) which is mainly due to some scholars and Ford (1995). We applied the new proposed method with two-step iterative method to solve test example in order to assess their validity and accuracy. The results obtained reveals that the modified method is accurate and efficient with a lesser number of iterations compared with the other standard methods such as NRM.

Published: October 2023

In a host of mathematical applications, the bounded linear transformation arises. The aim of the present work is to report the definition of continuous for linear transformation by using the idea of G-fuzzy normed linear space (GFNLS) with proving the main theorem regarding the continuity. Besides, the notion of a bounded linear transformation depending on GFNLS is presented and some basic properties related to this notion are proved. Furthermore, the extension of a bounded linear transformation is discussed and proved. Finally, a characterization for the notion G-B(X,Y) which is consisting of all bounded linear transformations is presented and proved that this characterization is a complete GFNLS if the space Y is complete.

With a large rise in crime globally, there is a necessity to analysis crime data to bring down the rate of crime. This encourages the police and people to occupy the required measures and more effectively restricting the crimes.     Crime analysis and spatial analysis using Geographic Information System(GIS) tools such as hot spot generation, zoning, navigation and crime profiling, detection of mobile locations and various web-based applications are well known and can be used scientifically for citizens advancement, while crime prediction and control can be used effectively. Crime data analysts will enable the law enforcement officials to speed up the crime resolution process. We can analyze previously unknown, helpful information from unstructured data by using the theory of data mining. The purpose of this work is to perform a survey on the crime analysis by using several data mining techniques that has been applied towards criminal activities over the years to be a valuable guide to  young researchers that are interested in this field.
