Investigation of Microsoft Teams and Skype as Distance Education Tools ın Terms of Digital Forensics

necessity has disrupted traditional norms and has affected all aspects of life. Undoubtedly, the education sector is one of the most significant areas affected by technology. As the population rate increases, the importance and necessity of education also increase. In response to this need for education, new educational models emerge based on the contemporary conditions. One of the critical factors that lead to the emergence of these new models is the COVID-19 outbreak that affected the entire world in March 2020. As a result of this epidemic, countries have adopted various methods in the field of education and training. Some countries suspended their educational activities, while others have continued the process through distance education. Distance education is a teaching method that relies heavily on the active use of information and information tools. The extensive use of distance education tools can attract the attention of malicious individuals who may seek to access these services directly or indirectly. This study aims to present the data and information obtained from analyzing the traffic information stored by Microsoft Teams and Skype or incoming and outgoing traffic information over the network in an isolated environment. The study was conducted on computers with the Windows 10 operating system and web client applications installed. One of the primary goals of this study is to assist researchers who will study distance education tools in the future.

MapSafe: A complete tool for achieving geospatial data sovereignty

AbstractSensitive geographic data are invaluable assets for the people to whom they belong and their disclosure should be decided by the sovereign data owner (SDO). Due to several high‐profile data breaches and business models that commercialize user data, the need for new approaches to geoprivacy and data sovereignty has grown. We propose MapSafe, a client web application that first obfuscates datasets using donut masking or hexagonal binning, separately, and thereafter implements a multi‐level encryption scheme that permits SDOs to share the final encrypted volume containing the geospatial information when they choose and at a level of detail which they are comfortable. The authenticity verification of the volume is facilitated by storing the hash value corresponding to the encrypted volume immutably on the Blockchain as a public record. Our approach places geoprivacy under data guardians'’ control, and its integration capabilities promote its adoption in existing and future geospatial web systems.

A Model Driven Approach for Unifying user Interfaces Development

In this paper, we dealt with the rapid development of client web applications (frontend) in a context where development frameworks are legion. In effect with the digital transformation due to the COVID-19 pandemic we are witnessing an ever-increasing demand of the application development in a relatively short time. To this is added the lack of skilled developers on constantly evolving technologies. We therefore offer a low-code platform for the automatic generation of client web applications, regardless of the platform or framework chosen. First, we defined an interface design methodology based on a portal. We then implemented our model driven architecture which consisted of defining a modeling and templating language, centered on user data, flexible enough to not only be used in various fields but also be easily used by a citizen developer.

Lazy Loading Based with Load On Demand and Currency Support in Web Browser

In this work our goal is to make a Web client application for the Real Estate Business. We already have a Stand-Alone Application for the same, so we are migrating from Online Application to the Web Client. Here for this we are using XPA tool which is a tool to move a project and make changes as per necessity. During this, we designed the editing function size and position adjustment, hiding and displaying, style editing, editing by device type etc. for every device type such that the contents will be dynamically converted according to resolution or screen-size in step with various devices. To be able to answer various devices, storing device information in an exceedingly component is created through editing function. With this, we have worked on Currency Format support in Web Client application and implemented a concept of Lazy Loading. Responsive web functionality improve server throughput that shows the response function of Web Client and therefore the processing speed is improved. All features can operate in real-time manners with our software architecture and loading mechanism, called Lazy Loading.

Energy and quality of experience aware web browsing for smartphones

In this paper we propose a framework for improving the web browsing experience of users by reducing battery energy consumption and webpage load time, while maintaining the quality of experience for the user. This is made possible through a collaborative protocol between the web server and the web client application that works using HTTP header fields. The innovation herein lies in dynamically creating multiple versions of the webpages that differ in their quality of content and size, and then delivering an appropriate version to the client based on metrics related to the webpage and the user's phone relevant specifications. These metrics include the user's battery consumption profile, user's network speed, the sizes of the different versions of the webpage, and the estimated energy consumption of the versions. We implemented a prototype and validated the system in terms of maintaining the battery profile and enhancing the load time of different webpages. The results indicate that over 50% reduction in power consumption and 80% reduction in speed requirements (and hence download times) can be achieved as a result of switching over to a lower quality version of the webpage that is still in line with the users’ experience.

Internet of Things: Design and Manufacture of Home Automation System with Web Server Based Arduino and Android

Home automation is an automated system created specifically to facilitate the work of humans, especially at home. Home Automation connects electronic devices to each other in a home that is integrated using the internet network and allows it to be controlled via android smartphone and web client (server). On android smartphone installed applications that have been connected with Arduino microcontroller and Ethernet shield. In this research for controlling or retrieving data via Ethernet network the easiest is Arduino serve as server and we can request and arrange data through web client or android application then data will be sent using protocol User Datagram Protocol (UDP). So to control the electronic devices can be done from a considerable distance as long as connected to the internet.

Schema-Based JSON Data Stores in Relational Databases

JSON is a simple, compact and light weighted data exchange format to communicate between web services and client applications. NoSQL document stores evolve with the popularity of JSON, which can support JSON schema-less storage, reduce cost, and facilitate quick development. However, NoSQL still lacks standard query language and supports eventually consistent BASE transaction model rather than the ACID transaction model. This is very challenging and a burden on the developer. The relational database management systems (RDBMS) support JSON in binary format with SQL functions (also known as SQL/JSON). However, these functions are not standardized yet and vary across vendors along with different limitations and complexities. More importantly, complex searches, partial updates, composite queries, and analyses are cumbersome and time consuming in SQL/JSON compared to standard SQL operations. It is essential to integrate JSON into databases that use standard SQL features, support ACID transactional models, and has the capability of managing and organizing data efficiently. In this article, we empower JSON to use relational databases for analysis and complex queries. The authors reveal that the descriptive nature of the JSON schema can be utilized to create a relational schema for the storage of the JSON document. Then, the powerful SQL features can be used to gain consistency and ACID compatibility for querying JSON instances from the relational schema. This approach will open a gateway to combine the best features of both worlds: the fast development of JSON, consistency of relational model, and efficiency of SQL.

BlackWatch: Increasing Attack Awareness within Web Applications

Web applications are relied upon by many for the services they provide. It is essential that applications implement appropriate security measures to prevent security incidents. Currently, web applications focus resources towards the preventative side of security. While prevention is an essential part of the security process, developers must also implement a level of attack awareness into their web applications. Being able to detect when an attack is occurring provides applications with the ability to execute responses against malicious users in an attempt to slow down or deter their attacks. This research seeks to improve web application security by identifying malicious behavior from within the context of web applications using our tool BlackWatch. The tool is a Python-based application which analyzes suspicious events occurring within client web applications, with the objective of identifying malicious patterns of behavior. This approach avoids issues typically encountered with traditional web application firewalls. Based on the results from a preliminary study, BlackWatch was effective at detecting attacks from both authenticated and unauthenticated users. Furthermore, user tests with developers indicated BlackWatch was user-friendly, and was easy to integrate into existing applications. Future work seeks to develop the BlackWatch solution further for public release.

Using SWISH to Realize Interactive Web-based Tutorials for Logic-based Languages

AbstractProgramming environments have evolved from purely text based to using graphical user interfaces, and now we see a move toward web-based interfaces, such as Jupyter. Web-based interfaces allow for the creation of interactive documents that consist of text and programs, as well as their output. The output can be rendered using web technology as, for example, text, tables, charts, or graphs. This approach is particularly suitable for capturing data analysis workflows and creating interactive educational material. This article describes SWISH, a web front-end for Prolog that consists of a web server implemented in SWI-Prolog and a client web application written in JavaScript. SWISH provides a web server where multiple users can manipulate and run the same material, and it can be adapted to support Prolog extensions. In this article we describe the architecture of SWISH, and describe two case studies of extensions of Prolog, namely Probabilistic Logic Programming and Logic Production System, which have used SWISH to provide tutorial sites.

Developing a MTConnect Framework for RepRap Additive Manufacturing Machines

The MTConnect standard provides a bridge to bring networked physical manufacturing resources to cloud manufacturing environments. However, making legacy manufacturing equipment compliant with this new standard is still a difficult task. Regarding additive manufacturing machines, this issue has been poorly studied. To address the subject, this work introduces an MTConnect-compliant framework for shopfloor data access and monitoring of RepRap additive manufacturing machines based on Arduino open technology controllers. A communication channel based on TCP/IP protocol using an Ethernet module was incorporated into the machine’s system to extend the functionalities of RepRap 3D printers to connect to the Internet. Two MTConnect implementation architectures named Type 1 and Type 2 were proposed. A web-client application was also developed to validate the system by performing real-time machine monitoring over the Internet. The proposed MTConnect solution allows retrieving data of axes position, heat-bed temperature, hot-end temperature, material extrusion, current layer number and elapsed time from the web application, demonstrating feasibility to operate in cloud manufacturing environments.

Flood early warning system on the Đetinja river Basin in Serbia

The Đetinja river basin, in Užice, western Serbia, is ungauged. Many torrential floods have occurred there over the past decades. In the city of Užice, there are no rainfall intensity gauges, and it is impossible to provide the data needed to monitor torrential floods or make a timely response, which is a precondition for successful defense from them. An early warning system for torrential floods was designed, with three key elements: measuring devices in the basin and river, a server application and a web-client application. A hydrologic study was made to assess multiple scenarios, focusing on the analysis of real data to determine alarm criteria for oncoming floods. Alarm criteria were proposed, based on analysis of previous floods and measurements. Using the direct relationship between runoff, rainfall depth and intensity, the alarm criteria are based on precipitation and river stage. There are three levels: the first level ‘warning’, the second ‘regular flood defense’, and the third ‘emergency flood defense’. The earliest possible warning is of great importance, due to the nature and speed of onset of the process. The system plays a key role in active flood control and prevention, by providing the lead time to secure and strengthen the flood defense system, thereby minimizing the adverse impacts of torrential floods.

A Cloud Architecture for Teleradiology-as-a-Service.

Telemedicine has been promoted by healthcare professionals as an efficient way to obtain remote assistance from specialised centres, to get a second opinion about complex diagnosis or even to share knowledge among practitioners. The current economic restrictions in many countries are increasing the demand for these solutions even more, in order to optimize processes and reduce costs. However, despite some technological solutions already in place, their adoption has been hindered by the lack of usability, especially in the set-up process. In this article we propose a telemedicine platform that relies on a cloud computing infrastructure and social media principles to simplify the creation of dynamic user-based groups, opening up opportunities for the establishment of teleradiology trust domains. The collaborative platform is provided as a Software-as-a-Service solution, supporting real time and asynchronous collaboration between users. To evaluate the solution, we have deployed the platform in a private cloud infrastructure. The system is made up of three main components - the collaborative framework, the Medical Management Information System (MMIS) and the HTML5 (Hyper Text Markup Language) Web client application - connected by a message-oriented middleware. The solution allows physicians to create easily dynamic network groups for synchronous or asynchronous cooperation. The network created improves dataflow between colleagues and also knowledge sharing and cooperation through social media tools. The platform was implemented and it has already been used in two distinct scenarios: teaching of radiology and tele-reporting. Collaborative systems can simplify the establishment of telemedicine expert groups with tools that enable physicians to improve their clinical practice. Streamlining the usage of this kind of systems through the adoption of Web technologies that are common in social media will increase the quality of current solutions, facilitating the sharing of clinical information, medical imaging studies and patient diagnostics among collaborators.
