This type of scanner is found in most parts of the world, but especially in airports in the United States. Lately, the presence of these scanners is more and more common.
A study by researchers on these scanning devices shows that they emit certain radiation that is very harmful to humans. At the same time, through these devices, one can see everything under the clothes of those who pass through them, and this is accused by many people as a violation of human rights.
Normally, the information saved by scanners should be deleted as soon as it is seen by the authorities, but it was found that at some airports, TSA representatives in the United States did not delete certain photos and kept them in their database.
When a person goes through the scanner, the result of this scan is transposed as a picture on the controller screens. This picture appears as a negative, so you can see if metal objects are hidden under clothes.
At this stage, you can not distinguish the exact colors or shapes of the body, but through a simple process, the colors, shapes and the rest of the details can be seen very easily. This process requires a simple program that processes the picture in the sense that it reverses the colors, and the photo becomes a simple negative, a normal photo that captures the naked, naked body of the person who went through the initial scanner dressed.
This can be seen as a violation of human rights given that TSA representatives, who process these photos and should delete them immediately after the person has been checked, can see the body without clothes and other details. The details range from skin color to body shapes and other intimate aspects, so they should be deleted immediately.
