Browser Fingerprinting Using Web Assembly
Škuta, Matúš ; Koutenský, Michal (referee) ; Polčák, Libor (advisor)
The main goal of this bachelor thesis is the implementation of device identification using Web Assembly technology. In this work we are discussing the existing methods of device identification, methods to prevent identification and ways to circumvent these barriers. We are also getting acquainted with the Brave browser, which seeks to reduce the identification of devices on the Internet. We are explaining how Web Assembly works, what are its positives, negatives and if we are able to bypass various defences against device identification thanks to this new technology. Next, we are looking at the several web APIs we are using to identify devices, and we are introducing a few extensions designed to prevent or completely limit device identification. Existing security extensions limit the activity of the Web Assembly, for example this work shows that the Web API Manager extension can neutralize the test page implemented in this work.

Hybrid Application for Calibration of Camera Lenses
Dovhalenko, Dmytro ; Malaník, Petr (referee) ; Šimek, Václav (advisor)
The goal of this bachelor’s thesis is to design and implement a tool for correction of image distortion caused by the physical curvature of a fisheye camera lens. The theoretical part is concerned with available solutions analysis in order to find an image distortion correction tool that uses modern technologies. The technologies are analyzed and described to find alternative points of view resulting in a way to change software delivery process and deliver a tool in the form of a web application. The thesis takes into account the necessity to deliver a tool that can be developed and deployed in a context of corporate environment. It focuses on the issue of generating settings for hardware-accelerated image correction since it is used more frequently in the real world than its software counterpart. The practical part analyzes various usage scenarios, suitable architecture design as well as user environment design. To achieve this, hybrid web technologies in combination with OpenCV library in the form of a web assembly, as well as other modern tools such as SSO authentication and browser’s built-in storage are used. This thesis will benefit mostly customers in need of modern image distortion calibration solutions. It proves that it is possible to use hybrid web applications to deliver native application alternative that simultaneously increases user comfort. The thesis also provides data important for transformation of native applications into hybrid web applications.
