Abstract: A software product and a method a method determines classification of text displayed within a browser on a computer. A processor within a server is used to generate a consolidated index of tokens contained within the text. The processor is used to identify a first classification of the text by matching each of one or more terms of a first association defined within a rule set with the tokens of the consolidated index. The first association associates the one or more terms with the first classification. The first classification is indicated with the text by interacting with the browser. The server may continually receive characters from a communication stream and report any matched classifications therein.
