Krčma, Marek ; Mészáros, Jan (advisor) ; Buchalcevová, Alena (referee)
This bachelor thesis deals with the identity management in the SaaS environment. The first part of the thesis defines and connects the areas which identity management is related. These areas are: cloud computing, authentication and authorization, legislation and standards. In areas of cloud computing, authentication and authorization is taken emphasis on security issues. The next part of the thesis compares three authentication and authorization standards (OpenID, OAuth and SAML) that are appropriate solution of the identity management in SaaS applications. The thesis defines the specifics for each standard and specifies the requirements for effective implementation. The last part describes how to implement OpenID authentication standard in an existing web application.

Karády, Gabriel ; Pavlíček, Luboš (advisor) ; Gála, Libor (referee)
The purpose of this thesis is to describe and compare password managers for users and small teams on different software and hardware platforms. It deals with the problem area of passwords in general, user habits, and comfort and password quality. It further introduces and categorizes password managers and compares a few of them by several criteria, from security -- used encryption and its cryptanalysis, user protection from malware -- through usability -- the abilities and ease of use of the tool, its integration with applications and the operating system -- up to teamwork enhancements -- synchronization abilities and sharing of both single passwords and password databases.

Residual Strains of Arteries as Forensic Index
Adámek, T. ; Horný, L. ; Chlup, Hynek ; Žitný, R.
It has been known for long time that arteries are pre-strained in situ. These residual strains play crucial role in arterial load-bearing capacity. However, to the best of authors’ knowledge they have never been considered from forensics point of view. This paper concerns a possibility of employing the longitudinal pre-strain of human aortas as an indicator of human subject age. Lengths of abdominal aorta were measured within autopsies before and after segment resection. Longitudinal stretch ratio was calculated for 45 male and 12 female cadavers. It was found that both male and female data samples give approximately the same mean of the stretch ratio = 1.2. The correlation coefficients between the pre-strain and age were R=-0.7926, R=-0.8684 in male and female samples, respectively. Linear regression equation with confidence intervals was employed. The correlation between pre-strain and age seems to be suitable statistics to be used in forensic sciences.

Comparsion of classic and modern authentication methods
Koudela, Radek ; Doucek, Petr (advisor) ; Cidlina, Jaroslav (referee)
Owing to the growing significance of data protection and informatics in general, the importance of information system security counts among the most actual topics at this time. The main goal of this work is to give a comprehensive overview of the issue of users' authentication, including current trends on this field. There are also described the principles and working methods of classic and modern authentication methods, and listed their pros and cons. The main benefit lies in the comparison of these methods as well as in the evaluation of their deployment. As a result of this are suggestions, which can managers take into account when deciding about the method of authentication, and a description of weak points that need an attention. One part of this work also includes a reliability and performance test of modern biometric device.
