Backscatter technology - Where Do governments the boundary between security and privacy?
In the name of security companies from around the world are struggling to define the boundary between privacy and surveillance. Iris recognition scans to identify with peering into our eyes and taking advantage of the uniqueness of an internal part of the human body. What would you say if there is an inspection machine in use that can actually see through us and do not perform the electronic equivalent of a search? If it hurts? The use of such a machine would undoubtedly privacyArguments.
The technology is called "backscatter X-ray and advanced imaging technology. This is one of the two types of whole body imaging technology is used to scan the whole body of the passengers. On the positive side, this machine could be used to detect plastic concealed weapons, explosives, drugs, cash and other contraband are not collected by other X-ray inspection systems However, raises privacy concerns in the image of the object looks like a nude photoexcept perhaps for the hidden explosive device on the body.
Backscatter can monitor more than persons. It can be used for freight and general control. There are companies that are mobile, adjustable and fixed-site monitoring systems to determine. This configuration is valid for the testing of cars, vans, trucks and air and sea, ideal for hidden threats and contraband.
While working in a similar X-ray backscatter reveal things about losing a regular X-rays.The technology is based on backscatter X-ray Compton scattering effect, and the work backscatter imaging systems electronically generated high-energy rays of light on an object-based. The backscatter image data captured by X-ray photons, which went from being inspected are missing. X-ray photons scatter differently when they encounter different types of materials. Compton scattering depends on the material, the materials with lower atomic number higher than the scatteringPatterned. Organic matter, especially explosives contain low atomic number elements like carbon, oxygen, hydrogen and nitrogen.
These high-energy radiation to penetrate dense objects, like metal, but the bounce when they hit back-scattering and low density materials such as explosives, drugs, cigarettes, and people, especially if hidden in a complex environment. As the spread of the light once again reveals the shape and form of objects provides the context and clarity ofSpeed up inspections.
The technology creates clear, concise, two-dimensional, photo-like X-rays, the screener provides fast and accurate interpretation of the images. It also produces these images by emitting a radiation dose much lower than for the loading and the environment.
For example, with a normal X-ray machine a fruit truck can not raise suspicions taken into account. By controlling a radical beam X-ray machine at the truck would be a backscattertraces of drugs or people, if any. You can understand why, if used at the edge of the world, backscatter is an effective barrier to smugglers. This technology would put things in a moment that could be related to the hours of border guards to reveal.
This is the argument that this technology can be invasive. privacy advocates are concerned that implements a virtual strip search provide authorities with a framework that leaves nothing to be desired imagination. BritishOfficials are concerned that the use of scanners that scan children be illegal. We have also been the subject of different cultures on issues such as modesty and in conflict with their religious beliefs. It 's true that this technology is invasive, however, is that these machines are in support of the authorities to tighten security, where it is needed most.
