Abstract

The article describes solution path of the problem of information automatic copying from web-sites in the Internet, which is implemented using parsing techniques based on regular expressions or function libraries. To protecting against this type of information security threat, it is proposed to dynamically generate and periodically change the object model of the HTML document when generated and sent to the browser. These changes should affect the values of the identifying tag attributes and the structure of the object model tree. As attribute values it is offered to use character sets of limited length obtained as a result of random numbers hashing; change of the structure of the object model should be done by adding of additional tags at the corresponding levels of the hierarchy of the tree representing it. The simultaneous application of these methods excludes the possibility of algorithm compile for the necessary information extraction in the overall structure of the web page.
