An Analysis of Memory Usage in  Web Browser Software

Web browsers may delete some files but it doesn’t delete everything. The purpose of private browsing is for users to browse private mode just as a standard browsing session would, but without storing any data such as log-in credentials or browsing history upon exit. A secure framework to secure the web browser artefacts is proposed to fulfil the requirements. In order to compare and contrast the different methods of artefacts encryption, a hybrid method was introduced; Base64 + AES on the prototype. The test systems were created by utilising virtual machines. The prototype was developed using C# language in Microsoft Visual Studio application that runs on Windows. To provide countermeasures, this research proposes an implementation of a third-party privacy application, called PRINDOW, to improve security in hiding a user's browsing activity. Every browsing session is recorded and scanned using the prototype. This method allows only the base requirements to be installed on the virtual machine for each file with the cryptographic method. This framework could theoretically enhance current practises by making slight changes to the web browser's application structure.

Real-time web applications such as a virtual world require considerable computing resources. However, as the number of servers increases, so does the maintenance and financial cost. To share tasks among web browsers, the browsers must share data. Therefore, a network must be constructed among the web browsers. In this paper, we propose the construction of a web browser network based on the Barabasi–Albert model (BA model). We focus on a web-based multiplayer online game that requires higher frequent communication and significant computing resources. We attempt to optimize computing resource utilization for web browsers. We improve upon the method in our previous study, which constructed a network for a web-based virtual world, using only location information. When a new user logged into a world, the web browser connected to two other browsers whose users had a location close to that of the user. The experimental results of that method showed 50% data coverage, which was insufficient to display the game screen because the web browser displays the characters on the virtual world. In this study, we attempt to use the BA model to construct more efficient networks than those in the previous study to increase data coverage. Our new method uses the number of connections of the web browser and location information to calculate the probability of web browser selection. The experimental results show that the data coverage exceeds 90%, indicating significant improvement over the previous method.

This chapter focuses on the Internet working environment of Knowledge Workers through the customization of the Web browser on their computer. Given that a Web browser is designed to be used by anyone browsing the Internet, its initial configuration must meet generic needs such as reading a Web page, searching for information, and bookmarking. In the absence of a universal solution that meets the specific needs of each user, browser developers offer additional programs known as extensions, or add-ons. Among the various browsers that can be modified with add-ons, Mozilla’s Firefox is perhaps the one that first springs to mind; indeed, Mozilla has built the Firefox brand around these extensions. Using this example, and also considering the browsers Google Chrome, Internet Explorer, Opera and Safari, the author will attempt to demonstrate the potential of Web browsers in terms of the resources they can offer when they are customizable and available within the working environment of a Knowledge Worker.

The students consider learning Javanese script to be difficult particularly in distinguishing and memorizing Carakan, and memorizing Sandangan and Pasangan with its writing rules. This work intends to develop a supporting medium for learning Javanese script. The development process is started by defining the game functionalities by using the use-case diagrams, and then, the activity diagram is created to describe the workflow of the game algorithm. The database to support the game is also created and displayed by using the physical data model. Afterward, the game algorithm script is created using JavaScript so that the game can be played through a web browser. There are 27 respondents requested to test the game and to fill in questionnaires about the web application. The results suggest that 100%of respondents agree that the web application is necessary and useful to learn Javanese script. The application provides positive benefit to the users such as students who still need to learn Javanese script in schools with 97% average success rate to run the game

The VLab (Virtual Laboratory), developed in the context of the European projects ECOPOTENTIAL and ERA-PLANET, is a cloud-based platform to support the activity of environmental scientists in sharing their models. The main challenges addressed by VLab are: (i) minimization of interoperability requirements in the process of model porting (i.e. to simplify as much as possible the process of publishing and sharing a model for model developers) and (ii) support multiple programming languages and environments (it must be possible porting models developed in different programming languages and which use an arbitrary set of libraries).In this presentation we describe how VLab supports a multi-cloud deployment approach and the benefits.In this presentation we describe VLab architecture and, in particular, how this enables supporting a multi-cloud deployment approach.Deploying VLab on different cloud environments allows model execution where it is most convenient, e.g. depending on the availability of required data (move code to data).This was implemented in the web application for Protected Areas, developed by the Joint Research Centre of the European Commission (EC JRC) in the context of the EuroGEOSS Sprint to Ministerial activity and demonstrated at the last GEO-XVI Plenary meeting in Canberra. The web application demonstrates the use of Copernicus Sentinel data to calculate Land Cover and Land Cover change in a set of Protected Areas belonging to different ecosystems. Based on user&#8217;s selection of satellite products to use, the different available cloud platforms where to run the model are presented along with their data availability for the selected products. After the platform selection, the web application utilizes the VLab APIs to launch the EODESM (Earth Observation Data for Ecosystem Monitoring) model (Lucas and Mitchell, 2017), monitoring the execution status and retrieve the output.Currently, VLab was experimented with the following cloud platforms: Amazon Web Services, three of the 4+1 the Coperncius DIAS platforms (namely: ONDA, Creodias and Sobloo) and the European Open Science Cloud (EOSC).Another possible scenario empowered by this multi-platform deployment feature is the possibility to let the user choose the computational platform and utilize her/his credentials to request the needed computational resources. Finally, it is also possible to exploit this feature for benchmarking different cloud platforms with respect to their performances.&#160;ReferencesLucas, R. and A. Mitchell (2017).

AbstractThere is an increasing trend in moving desktop applications to web browsers, even when the web server is running on the same desktop machine. In this paper, we go further in this direction and show how to combine a web server, a web application framework (enhanced to support desktop-like Model–View–Controller interaction) and a context-aware architecture to develop web-based mobile context-aware applications. By using this approach we take advantage of the well-established web paradigm to design the graphical user interfaces (GUIs) and the inherent ability of the web to mash up applications with external components (such as Google Maps). On top of that, since the web server runs on the device itself, the application can access local resources (such as disk space or sensing devices, which are indispensable for context-aware systems) avoiding the sandbox model of the web browsers. To illustrate our approach we show how a mobile hypermedia system has been built on top of our platform.

Cross-Site Scripting (XSS) attack is a vulnerability on the client-side browser that is caused by the improper sanitization of the user input embedded in the Web pages. Researchers in the past had proposed various types of defensive strategies, vulnerability scanners, etc., but still XSS flaws remains in the Web applications due to inadequate understanding and implementation of various defensive tools and strategies. Therefore, in this chapter, the authors propose a security model called Browser Dependent XSS Sanitizer (BDS) on the client-side Web browser for eliminating the effect of XSS vulnerability. Various earlier client-side solutions degrade the performance on the Web browser side. But in this chapter, the authors use a three-step approach to bypass the XSS attack without degrading much of the user's Web browsing experience. While auditing the experiments, this approach is capable of preventing the XSS attacks on various modern Web browsers.

This paper discusses the issue of comparing Java and Kotlin technologies based on the web application framework. The criteria taken into account for testing purposes are: execution time, memory usage, CPU load, database response in set time. A series of tests and their in-depth comparative analysis are carried out. For this case, tests and code analysis were carried out to draw comparative conclusions. The performance in terms of web frameworks, database response speed and tests implementation in different languages - in all these Kotlin proved to be less efficient. There is no significant difference between CPU load between individual easurements, the difference does not exceed 2%. Implementation in the Kotlin language has never achieved the best result in any group of measurements.

The web application approach has become widespread in recent years due to the development of the Internet. Modern web browsers have enough processing power to run complex web applications and are not limited to just websites. During the development process, various methods for constructing surfaces and visualization methods were analyzed to choose the most optimal solution for web applications. We analyzed and presented basic methods of creating 3D surfaces. We highlighted the key differences between wireframe and polygonal methods of surface definition. We considered several models with dynamic surface computation. We described the kinematic method of surface formation in detail and the developed algorithm for transforming kinematic models into a surface using a polygonal mesh. We described in detail the rendering process and ray tracing method. We demonstrated a way of working with a video chip and parallelizing computations to optimize a web application using the GPU.js library. We presented the structure of a web application with a description of the main project directories. The project structure is based on the Vue.js framework. The framework allows one to endlessly expand the functionality of a web application. The article presents how the web application works and example of step-by-step creation of a kinematic surface and rendering on a scene using graphic effects such as shading and lighting. Also it contains an example of rendering many objects on a scene
