PUBLIC CONCERNS ABOUT PRIVACY Privacy is likely to be the most significant public acceptance issue associated with imaging technologies. Displaying an image of the body on a monitor will obviously be of concern to a significant percentage of people passing through screening checkpoints.

Portals necessitate close contact between the person being screened and the screening equipment; hand-wand devices require close contact between the person being screened and the screening operator. As with the privacy issues, the comfort issues associated with contact trace technologies may prove to be a significant implementation hurdle because the desire to keep an optimum distance from other people and objects is deeply ingrained.

The variables that affect public acceptance of specific screening systems and procedures include the following: · the nature, extent, and likelihood of the actual threat and the associated risks · the degree of understanding and the perception of the actual threat and the associated risks · personal beliefs, habits, and cultural mores the physical, mental, and emotional state of an individual the extent and degree of public understanding of the screening objectives, technology, and procedures · public perception of the effectiveness of the screening system · public understanding and perception of the health risks associated with the screening system · the nature and frequency of air travel One way to assess public acceptance of alternative screening systems and procedures is to conduct a survey of the population most likely to be affected by passenger screening. However, obtaining useful, definitive results from such a survey involves significant difficulties because of the potential extent of sampling and measurement error.

SOME POSSIBLE PUBLIC ACCEPTANCE CONCERNS ASSOCIATED WITH SPECIFIC SCREENING TECHNOLOGIES Imaging Technologies Active imaging technologies involve the use of electromagnetic radiation, such as x-rays, to produce images of individuals and objects that may be concealed under clothing. The use of any type of electromagnetic radiation, regardless of the dose applied, will raise concerns about possible biological damage due to radiation.

People trained to detect threat objects on this type of distorted image may be effective screeners. Research into how much image distortion is feasible, without compromising screening effectiveness, may yield answers to help improve public acceptance of imaging technologies.

From page 51... ...
Convenience in the form of 51 avoiding time delays appears to be a highly important factor in public acceptance, as well as in the overall successful functioning of the system. Technologies that take more than six seconds to screen each person are likely to encounter significant public resistance.
