NEW YORK - Thursday, November 10, 2005 - (Investrend Research Syndicate) -- Investors need look no further than the headlines, such as the Jordanian bombings of American interests such as the Radisson, Hyatt and Days Inn facilities, to recognize that sharply increased revenues and earnings for viable companies in the now globalized homeland security sector have every prospect of becoming an indelible, urgent and irreversible trend for the foreseeable future.

Companies such as Digimarc Corp. (NASDAQ: DMRC - News) and Viscount Systems (OTCBB: VSYS - News), included in Spotlight reports incorporated into the Q3 Homeland Security sector Update, are among those poised to take advantage of these escalating developments.

The Update was authored by Investrend Research analyst Ryan Fuhrmann, CFA, who initiated the continuous coverage commissioned by Cronus Capital Markets (http://www.cronuscapitalmarkets.com) in partnership with the 400-member Homeland Security Industries Association (http://www.hsianet.org) in August.

Cronus also administers and publishes the homeland security sector index in partnership with the International Securities Exchange (NYSE: ISE - News).
