ImageWare Systems Granted Another Patent on Multimodal Biometric Technology

Wednesday, April 23, 2008

San Diego, CA -- ImageWare Systems, Inc. (AMEX: IW), a leading developer of identity management solutions, today announced that has been awarded another patent, number 7,362,884, by the United States Patent and Trademark Office (USPTO), for its multimodal biometric fusion and analysis technology.

This patent describes a system and method for utilizing multiple biometrics to improve the performance and accuracy over use of a single biometric for identification and authentication purposes. The multimodal method, called biometric fusion, combines biometric search results on multiple biometric identification markers to be brought together into a single result with a higher level of accuracy and reliability. ImageWare utilizes a suite of fusion and normalization techniques for comprehensive identity verification. The patent, titled "Multimodal Biometric Analysis," is employed throughout ImageWare’s portfolio of biometric identity management solutions and marketed under the IWS™ Biometric Engine® product suite.

"We are very pleased with this patent as it builds on our technology portfolio and provides broader coverage of our Biometric Engine solutions," said Jim Miller, ImageWare’s chairman and CEO. "This recognition is yet another acknowledgment of our market leadership. We are seeing new players entering this rapidly expanding market and these patents will help protect our intellectual property while we focus on delivering innovative solutions to our customers."

This patent joins another recently received ImageWare patent, number 7,298,873, by the USPTO for a multimodal biometric identification and authentication system. This foundational patent describes a system or method for enrolling, searching, matching, and managing biometric modalities on a common platform, and is independent to the biometric types or the algorithms managed. The patent, titled "Multimodal Biometric Platform," is also employed throughout ImageWare’s portfolio of biometric identity management solutions and marketed as the IWS Biometric Engine.

The IWS Biometric Engine is a multi-biometric identity management solution used by government and commercial enterprises to biometrically search and match populations of unlimited sizes for identity confirmation. These include searching and matching for Verification of an Identity (1:1), Exhaustive Search for Identification (1:N), Watchlist Management (X:N) and Existing Biometric Population Management and Enhancement (N:N). IWS Biometric Engine employs a multi-biometric enrollment, management and authentication platform that is technology agnostic, enabling users to utilize biometric devices (over 120) and algorithms (over 90) from virtually any vendor, as well as support the combination of the following biometric types, including: single fingerprint, Livescan fingerprint, 2D face, 3D face, iris, palm scan, finger vein, palm vein, hand geometry, palm, DNA, signature, voice, and retina.
