In the paper we propose a method of detecting and removing a hidden content which
could be sent through the HTML code of WWW pages. We start from the overview of known
methods of inserting hidden data to the mark-up languages (HTML or XML)-written texts.
Next we propose a method of detecting suspicious web pages, based on statistical analysis.
We also propose the method of transforming the HTML code of the web pages to remove any
hidden communication.
