ON-THE-FLY PATTERN RECOGNITION WITH CONFIGURABLE BOUNDS

摘要

Some embodiments of on-the-fly pattern recognition with configurable bounds have been presented. In one embodiment, a pattern matching engine is configured based on user input, which may include values of one or more user configurable bounds on searching. Then the configured pattern matching engine is used to search for a set of features in an incoming string. A set of scores is updated based on the presence of any of the features in the string while searching for the features. Each score may indicate a likelihood of the content of the string being in a category. The search is terminated if the end of the string is reached or if the user configurable bounds are met. After terminating the search, the scores are output.

1. A method for filtering data, the method comprising:
receiving an incoming dataset at a firewall, the incoming dataset directed to a receiver device; receiving a pattern matching engine at the firewall, the pattern matching engine based on a plurality of scores, where each score of the plurality of scores is based on identification of a plurality of features within at least one string meeting user-defined bounds; classifying the incoming dataset into a first category of a plurality of categories based using the pattern matching engine; and determining whether or not the incoming dataset should be transmitted to the receiver device based on the first category.
