METHOD AND SYSTEM FOR VIRUS DETECTION USING PATTERN MATCHING TECHNIQUES

A method and system for providing virus detection. A virus detection system provides for the use of pattern matching techniques on data at a binary level for virus detection. Whenever an incoming data stream is received, the data stream is segmented into time-based data frames. The time-based data frames are processed to generate associated data frame images utilizing signal processing identification and filter techniques. One or more data frame images are compared to a stored virus image utilizing pattern analysis techniques. A pattern match value associated with each data frame image is generated based on the comparison and a determination is made as to whether or not the pattern match value exceeds a pattern match value threshold. When the pattern match value exceeds the pattern match value threshold, a pattern associated with the virus image is removed from the time-based frames to produce a filtered data stream.
