Guardian Technologies' PinPoint Software Resolves Security Issues of Threat Identification, Privacy

British Government Reveals Scanners Fail to Detect Most Explosives

HERNDON, VA--(Marketwire - January 6, 2010) - With new airport security screening recommendations coming out almost daily, it's difficult to separate facts from marketing spin and balance the need for public safety with privacy rights. The security experts at Guardian Technologies International (OTCBB: GDTI), a digital image analysis technology company that specializes in threat detection, believe that PinPoint, an automated threat detection and identification software application, holds the answer to the many issues facing governments around the globe -- high investment cost of new equipment, detection and identification proficiency, and individual privacy.

Listed below is an analysis of the principal security challenges and the solution that PinPoint represents to solving those challenges.

The Challenges

-- Full-body scanners. Putting aside the arguments of high cost and privacy concerns -- do they actually work? According to a January 3rd article in the UK's "The Independent," studies done by the British Department for Transport (DfT) and the Home Office showed full body scanners do not currently detect most explosives. ( They noted that currently deployed millimeter wave body scanners don't accurately detect (indicating the location of an object within the image) low-density explosives, including liquid and powder explosives. Without detection of the object there can be no discrimination between threats and non-threats, and therefore no identification of explosives.

-- Baggage scanners experience many of the same issues as the full body scanners in detecting explosives. Current scanner hardware technology is unable to discriminate between various threat and non-threat items, such as explosives or household products like peanut butter, chocolate, honey and cheese.

The inherent challenge with all current scanners is that the decision-making process, the determination of threat or no threat, relies on human screeners to interpret the items within the image. The physiology of the human eye severely limits the physical capacity, of even the best-trained human screeners, to distinguish and identify most types of explosives from similarly presented non-threats. Human visual identification of objects relies largely on shape/appearance recognition, and explosives don't have uniform and recognizable shapes. Only machine recognition software, integrated with the current scanning hardware, can provide the ability to distinguish between the minute characteristic differences in images that aren't physically possible for the human eye to detect.

A Solution

Because of the long-known challenges in explosives detection, Guardian Technologies developed PinPoint™ threat detection and identification software to be compatible with a wide range of scanner technologies. PinPoint removes the limitations of human vision from threat detection. Using computer analysis and algorithms, PinPoint distinguishes between minute variations in digital images that are impossible for the human eye to differentiate. It compares characteristics in the image to known digital signatures for threat items. Since the PinPoint technology relies on the digital image data feed, rather than the technology used to acquire the image, it can be made compatible for all scanner platforms/manufacturers.

Facts About PinPoint

--  Proven effective at accurately detecting and identifying explosives 
    of varying densities (including liquid and powder explosives) with a low 
    false positive rate in testing with numerous international government 
--  It is compatible with all digital imaging technologies, including 
    millimeter wave, backscatter and advanced x-ray technologies used in full 
    body and other scanners.  It is also capable of screening cargo from 
    digital X-ray images.  
--  Video footage of PinPoint in use on a millimeter wave full-body 
    scanner demonstrates its ability to quickly and accurately detect threat 
    items while protecting personal privacy. (link to video:
--  It is believed that this is the only software capable of actually 
    identifying which type of explosive (i.e. C4, PETN, etc.) is present in a 
    digital image with a high degree of accuracy and single digit false 
    positive rate.  
--  It is also believed to be the only software currently in existence 
    that has been able to detect certain types of liquid explosives with a high 
    degree of accuracy and a low false positive rate in 'proof of concept' 
    testing with a major country's government security agency.
