Scientists have created a quick skeleton scanner to detect criminals

    I remember in a movie (or even several), I saw a situation where a criminal was found thanks to a scanner that "saw the root", that is, it showed the full skeleton of the criminal on the screen, against which the weapon stood out beautifully. I don’t remember the film (“Remember everything” or something), but this scanner has already migrated from cinematic scenes to the laboratory of institutes. At least almost such a scanner was developed by scientists from the Wright State Research Institute.

    According to the developers, their scanner will scan the skeleton of people at airports, stadiums, amusement parks and other public places that may be vulnerable to terrorist attacks. The image obtained by the scanner will be checked with the police database. That is, everything will be like it is now with fingerprints - there is a fingerprint database of criminals and people who have already come across the police before for any bad reason, there is an image obtained from the scanner. When reconciling we get the identification of the person.

    It is interesting that scanners created according to the technology developed by scientists will work at a distance of up to 50 meters. I don’t know how, but scientists promise the full operation of their devices at such a distance. The developers claim that both fingerprints and facial features can be changed. But the person is not yet able to change the bones. In an adult, the skeleton consists of 206 bones. The size, shape, density and structure of each bone is more individual than fingerprints. Particularly individual are the individual bones of the skeleton. In addition, a person can be identified by fractures, bone damage, implants and other details. All this is very individual and practically does not change (of course, if a person does not break his bones every year).

    Scientists claim that there is no need to scan the entire skeleton to identify a person. It is enough to choose some part of the body where the bones are most unique, so to speak, and scan this particular part. Now researchers are just working on determining the most unique part of the human skeleton, which can be used as an identifier. About 5 seconds are spent on a “snapshot” of one person, and another 10 is needed to identify the snapshot, that is, comparisons with the examples in the database.

    As mentioned above, the practical application of such a system is very extensive, taking into account also the advantage of a new type of scanner (unfortunately, there is very little information about it in the original source), such as "range." The developers believe that it will be possible to use such scanners in private companies, state closed facilities and so on.

    Not so long ago, a storm of indignation in Europe and the USA was caused by scanners that scan a person to their full height, while giving a picture of a person’s body without clothes (not quite clear, of course, but still). It is clear that such a system is not particularly popular with people. A skeleton scanner will help to avoid this, without "lighting up" anything but bones and solid objects, which can turn out to be a weapon. Two prototypes of skeleton scanners are already ready, and if necessary, a complete system can be deployed in about a year.
