QR code detection using deep learning
Černohous, Matěj ; Kříž, Petr (referee) ; Přinosil, Jiří (advisor)
This bachelor thesis deals with the design of an algorithm for detecting and decoding QR codes in images using deep learning techniques. The work involved the construction of 2 datasets, a YOLOv7 neural network model for detecting QR codes in images, a YOLOv4-tiny neural network model for detecting position markers of QR codes, and a Python program utilizing these models to read QR codes in images. For evaluation, the algorithm was compared with other options for QR code reading.

Exercises and problems in linear algebra
ČAPKOVÁ, Klára
The aim of this thesis is to create a collection of solved examples and problems of linear algebra, which could serve as a learning tool for the first-year students of the Faculty of Education of University of South Bohemia in České Budějovice. The most important part of this thesis is the electronic processing of the collection in a program GeoGebra and its visual interpretation of examples and problems by 3D pictures, QR codes and hyperlinks that specify the solutions.

Attribute Authentication on Android Platform
Strakoš, Jan ; Ricci, Sara (referee) ; Malina, Lukáš (advisor)
This master’s thesis focuses on implementation of ABC (Anonymous attribute-based credential) pilot system on the Android platform. The support for attribute authentication on the Android platform is very weak in terms of the number of implementations and needs a special attention. The theoretical part of the thesis describes the cryptographic support on the Android platform, the use of the Android Native Development Kit (NDK) and the Host-Card Emulation (HCE) service. The theoretical part of the thesis also includes a description of attribute authentication schemes, including a pilot RKVAC system. The practical part describes the implementation of the RKVAC system on the Android platform along with the implementation of a custom cryptographic kernel based on the native MCL cryptographic library. The practical part of this thesis describes implementation proces of RKVAC system on Android plaform, that uses native cryptographic library MCL. The final part shows the results of time, memory and computation difficulty of developed applications.

Informačný systém pre sledovanie potravín
Hrádela, Stanislav
This thesis deals with integration of company information system NetSuite to monitor the composition and origin of the food using QR codes to support small food producers. Analytical part of thesis contains the legislative aspect of food labeling within the EU and the Czech Republic, followed by functionality, advantages and origin of QR Codes. After that is introduced company Oracle + NetSuite and its business focus. In solution design part of thesis is discussed data structure of records in NetSuite system. Then are discussed possible solutions for QR code generation and their pros and cons. In the last part of analytical section is discussed creation of advanced PDF/HTML templates in NetSuite system. In the implementation part of thesis is described basic configuration of the system, applied solution of data structure of product records,continuing with selected QR Code and PDF generation solution. In evaluation part, the results of the integration of the solution are discussed, and at the conclusion section thesis deals with the added value of the solution and the possible extension of the solution in the future.

SAP Modul for Encoding Invoices to QR Codes
Švancar, Boris ; Hrubý, Martin (referee) ; Kočí, Radek (advisor)
The master's thesis deals with encoding payment data invoices into QR codes in accordance with the by square standard. The SAP system along with a process of encoding data into QR codes and by square PAY standard is introduced in my thesis. In compliance with the standard function module is designed for the SAP system which is in the ABAB language, using Smartforms form allowing the QR codes to generate the invoice. The module is then subjected to testing. The results are evaluated in conclusion of the master's thesis and a description of potential further development is assessed as a final step.

Secure data transmition using bar codes
Kratochvíl, Martin ; Herout, Adam (referee) ; Beran, Vítězslav (advisor)
The goal of this thesis was to create a system for visual data transmition using bar codes. It focuses mainly on the protection of the system against abuse. A mechanism was designed for the data transmition itself and the various security concepts. The most appropriate bar code for data transmition was selected on the basis of the analysis.
