For a long time, information hiding has focused on carriers like images and audio files. A problem with these carriers is that they do not support hiding in new types of network-based services. Nowadays, these services often arise as a consequence of the increasingly demand for higher connection speed to the Internet. By introducing streaming media as a carrier of hidden information, hiding in new network-based services is supported. The main purposes with this thesis are to investigate how information can be hidden in streaming media and how it measures up compared to images and audio files. In order to evaluate the approach, we have developed a prototype and used it as a proof of concept. This prototype hides information in some of the TCP/IP header fields and is used to collect experimental data as well. As reference, measurements have been collected from other available carriers of hidden information. In some cases, the results of these experiments show that the TCP/IP header is a good carrier of information. Its performance is outstanding and well suited for hiding information quickly. The tests showed that the capacity is slightly worse though.
