DENVER -- MX Logic Inc., a provider of innovative, easy-to-use email defense solutions for small and medium-sized businesses, has been granted U.S. patent #7,051,077 by the United States Patent and Trademark Office. The patent covers MX Logic’s method of identifying and controlling spam, which uses a sophisticated voting algorithm based on fuzzy logic that intelligently combines the results from multiple classifiers to achieve more than 99 percent accuracy.

The patented technology powers the MX Logic Stacked Classification Framework®, a spam-detection system that features multiple layers of spam classifiers working in combination to identify email messages as spam. As new spam-detection techniques and filters are developed, MX Logic adds them to the Stacked Classification Framework, further ensuring spam-filtering effectiveness.

“This patent validates MX Logic’s unique and powerful spam-detection technology, while further confirming our leadership position within the email security market,” said Scott Chasin, chief technology officer, MX Logic. “Because each spam classifier within the Stacked Classification Framework has specific strengths designed to identify particular threats, MX Logic’s patented technology is one of the most accurate and comprehensive in the industry. In addition, using a modular approach to email-threat protection enables us to add and retire filters as necessary to ensure that ours is the most effective defense against unwanted and harmful email.”

Using a different technique to analyze the spam probability of each email message, each spam classifier is given a single "vote." The votes are then combined in an intelligent manner using fuzzy logic — a type of logic that recognizes more than simple true and false values, but instead determines degrees of truthfulness and falsehood. By analyzing spam likelihood in degrees, rather than simply averaging the votes or using a majority vote, the MX Logic Stacked Classification Framework system results in a high rate of accuracy.

“A very effective way to combat spam and other email threats is by using a combination of filtering techniques,” said Chris Christiansen, vice president of security products and services, IDC. “MX Logic’s patented technology accurately identifies and blocks spam because it employs a layered approach that weighs probabilities rather than just relying on absolute values.”
