Under de senaste två årtionden har det blivit en drastisk ökning av privat ägda laptops. Detta har öppnat för nya möjligheter som bring your own device (BYOD) digitala prov i skolan. Men med detta blir nedlåsning av datorn inför digitalt prov ännu viktigare. Undersökningar har gjorts gällande elevernas uppfattning kring digitala provsystem samt deras åsikter om digitala prov i allmänhet. Andra arbeten har gjorts gällande hur digitala provsystem fungerar tekniskt men samtidigt finns det artiklar som visar hur viktig lärarnas åsikter är. Därför kommer detta arbete definiera kraven som de krav som lärare har för att undersöka deras perspektiv, inte på det digitala prov eller provsystem som andra arbeten utan på nedlåsningsprogrammet för datorn vilket bidrar med information i ett nytt perspektiv. Detta görs genom insamling av enkäter från lärarna på en gymnasieskola för att definiera krav. Dessa krav ställs sedan mot vanligt använda nedlåsningsprogram för att svara på hur de klarar av de krav som lärare har. Resultatet av detta visar att nedlåsningsprogrammen inte uppfyller alla krav som lärarna ställer. Dock vid undersökning av de krav som underkändes bedöms nedlåsningsprogrammen leva upp till en majoritet av lärarnas krav då anpassade lösningar och vikten av olika krav disskuteras. Detta ger ett positivt betyg för nedlåsningsprogrammen och ger uppmaning till lärare att gå över till digitala prov utan att oroa sig för nedlåsningen av datorerna.

I denna uppsats beskrivs gränssnittsproblematiken i dagens webbläsare. Syftet är att undersöka om användargränssnittet i webbläsaren hämmar användarna till att sätta sina individuellt anpassade säkerhetsinställningar. En stor del vardagliga sysslor utförs via webbläsaren, exempelvis hantera bankärenden eller ladda upp bilder på sociala medier. Därför finns det ett behov av att webbläsarens gränssnitt kommunicerar olika säkerhetsnivåer och inställningar så att alla användare kan använda och förstå de inställningar som erbjuds. Med hjälp av teoretiska utgångspunkter söker vi svar på eventuella brister i webbläsaren med hjälp av användarstudier. Genom att observera och intervjua våra försökspersoner kom vi fram till att det finns brister i webbläsaren som behöver utvecklas. Vi vill med vår uppsats öppna upp för en diskussion då vi vill förmedla importensen av att användare behöver känna sig säkra i webbläsarens gränssnitt för att kunna tillgodogöra sig information angående sin egen säkerhet. / In this paper we describe the problems with today’s web browsers within the interface. We are aiming to investigate whether or not the browser interface inhibits users from putting their personal safety settings. A great amount of everyday tasks are performed via the browser, for example banking transactions or uploading images on social media. Therefore the need of a browser user interface that can communicate different security levels and settings so that all users can understand and use the settings that are offered. With the help of theoretical starting points, we seek answers to any shortcomings in the browser interface through user studies. By observing and interviewing our subjects, we concluded that there are flaws in the browser that need to be developed. We want our thesis to open up for discussion in which we want to convey the importance of the users’ needs to feel safe in the browser interface to assimilate information about their own safety.

The author of this thesis aims to analyze and develop a prototype of a software responsible for showing how the specific web application would be displayed by the concrete device. First, the problem of diversity of devices for accessing the web and of the level of support of modern web technologies is explained to the reader. Then the thesis offers a way how to help developers with testing across web browsers on different hardware. The analytical section describes the methods the author would like to use for accomplishing the goal, and also the set of suitable technologies. The penultimate section shows the manner the author implemented the prototype of the software. The Software is then subjected to tests showing that the prototype meets the requirements.

This master thesis deals with the topic of browser extensions, their environment and analysis. The goal is to describe the extensions environment, online Webstores, that offers extensions and to show best practices for analysis and optimization of its extensions and their assets. Within the thesis you can find very precise analysis of online Webstores for Google Chrome extensions and Mozilla Firefox add-ons. Conclusions are made based on this analysis that include special characteristics of the previously mentioned browsers. The master thesis consists of two parts, theoretical and practical. The theoretical parts deals with the description of the browser extensions environment and it presents specific characteristics about online Webstores and browser extensions to the reader. In the practical part the thesis is focused on objectives set by the thesis and it presents the results of the Webstore analysis and description of the universal Google Analytics solution that helps developers to analyze their extensions The thesis contributes to the topic mainly with the precise description of the browser Webstores and extensions environment, best practices and recommendations and by creating the universal Google Analytics solutions for the developers.

Users of internet browsers are constantly monitored, without their consent. By using the JavaScript APIs, it is possible to obtain various information about the browser, which together form a browser fingerprint, which can then be misused. Therefore, the goal of this work is to use a robust fingerprint protection solution of Brave browser and port it to the JavaScript Restrictor extension. In this work, the problematics of obtaining an fingerprint and countermeasures in the Brave browser are analyzed and then compared with the current protection in the JSR extension. The method of porting of Brave's countermeasures is presented and subsequently the procedure of implementation of these defense elements into the browser extension is described. The resulting implementation has been tested and evaluated, with the new protection appearing to be effective.

This Master's thesis was written to create the extension for an experimental rendering engine CSSBox about scripting support in JavaScript language. In the theoretical section the thesis describes the architecture of the rendering engine and introduces problems of the scripting in HTML documents according to the recommended HTML 5 specification. This thesis deals with thorough analysis of existing scripting engines and their interfaces, which could be used for the extension implementation. Depending on the knowledge gained from the previous parts this thesis focuses only on the scripting engine Rhino and introduces an abstract design of its integration into the CSSBox project. At the end it evaluates the reliability and efficiency of the implemented functionalities and considers possibilities of their further development.
