Development of information technology and the Internet has co-created a new space, divided between physical and virtual reality. Due to its specific characteristics, the legal regulation of cyberspace was disputed during the first years after its emergence. Today, the dilemma whether international law and human rights apply to cyberspace is already resolved. The international human rights law was already able to explain; how certain human rights should be interpreted in the context of cyberspace. This can be said in particular for the freedom of expression and the right to privacy. Therefore, the core part of this master thesis is dedicated to their application on the internet. I am addressing topics such as blocking and filtering of web sites, liability of intermediaries, the significance of anonymity, mass surveillance, data retention etc. I also seek to highlight some other questions that still need to be resolved in the future, including extraterritorial application of human rights treaties, internet and economic, social and cultural rights and rights of the child.
