Bachelor thesis is dedicated to the problematics of digital footprints, to what extend the user is able to control it and protect his privacy by the use of freely available tools. In the first part the term digital footprint is analysed from several different points of view and the risks linked to their creation are explained. It is clarified how one can find the extent of his digital footprint and how to manage it. Next tools for providing protection from tracking, software for ensuring anonymity in the internet environment and techniques for potential removal of an existing footprint are analysed. The practical part is dedicated to choosing the right tools from the previous chapter and their mutual comparison for the purpose of finding out to what extend the user is able to protect his privacy and avoid possible risks. Conclusions are made from the results of the comparisons.

State informations keeping methods using HTTP
Novák, David ; Pinkas, Otakar (advisor)
The mission of this batchelor thesis is to give complete view to the problems concerning usage of interactive WWW services in the internet, where the communication is runned by HTTP protocol. This protocol is stateless. It means, that no information is stored between each connection. Nowday’s interactive web applications needs state informations for their proper functionality. That’s why this thesis considers methods of storing and transmission of state informations. In the first part is HTTP protocol described with mentions to the historical development. Actual version HTTP 1.1 is mainly focused. Next part is addicted to state informations, to the definition explanation, classification and methods of storing and transmitting theese informations. Following section is concerned with communication intermediaries in HTTP protocol. It means proxy and cache servers, which saves backup coppies of data for faster reusing and transmission capacities saving. This system brings along many problems, which are discussed in context of internet activity. References to extension of HTTP protocol for carrying state informations are highlighted. This is cookies. Their security risks are being discussed and also implementation in the relation to other methods is evaluated. In context of cookies is described P3P platform concerning protection of users privacy. Practical part consists of trivial application implementing the best of methods described here from the view of security and protection of privacy. Whole work might serve to the web application builder, it helps to understand patterns and to detect appropriate security risks.
