The doctor I can choose myself, I even can insist to take X-rays home with me. I don´t have these choices at a gate.

For one, it is rare any legitimate doctor would have to, or request t, see one´s naked body.  Doctors look at specific areas of a body, not the whole naked body at once.

For two, one chooses to see a doctor and has some choice in what doctor they will see. 

For three, there is a legal guarantee of privacy in seeing a doctor.

For four, one has the legal right to refuse treatment, if they so desire.

It is clearly a violation of one´s right to privacy.

Well, yersu, for one thing, doctors do not take your nude pictures, let alone store them in a database a huge number of other doctors have access to...

do not understand all the fuss..my body is perfect,no problem with being xrayed at the gate or perhaps a problem for those who may watch it?but still their problem not mine...

you´re free to go ahead and get yourself x-rayed as much as you want.

then what is your solution to this?

I´ve no problem being seen naked (no, i won´t post pictures ). But like I said, I don´t want my son to be seen naked and risk having his photo uploaded on a paedophil´s website. Also, it would stir my suspictions whether or not to get scanned if I were pregnant...

my solution is to create two-way tvs - you see them and they see you and monitor all your activity. an alternative would be installing chips into people´s brains to know exactly what they are thinking.

 So you think this is not the violation of privacy, according to some documentaries future slaves will be created by this method, you can be volunteer as a test subject for this ...

on a serious note, how that tv is supposed to work? how that tv would scan your hidden weapon or anything else? and why would i want to see what airport security does or doesnt? if i can monitor security, then they are not security anymore. those who monitor cant monitor all your activity.

good joke!

Thanks for your opinions but I still don´t think there is any violation of privacy here. I am sure there already is a term for what I am going to say but I don´t know it: I believe it can not be considered a violation of privacy as long as the observer does not have any connection or specific interest in the observee. No one would be disturbed about this whole scanning issue if it was completely executed by a computer, because the observer, in this case the computer, would not be concerned about you. But obviously; image recognition software isn´t that mature as of now, thus there is need for human assistance. So the securtiy guard looks at the picture before his eyes, not really different than what the computer does, and tries to recognize shapes in it. To the observer it isn´t a naked body, it´s a mathematical entity, a bunch of pixels which need to be identified.

Let a program which fills a picture with random pixels run for an infinite amount of time; and some of its output will be your naked photos, of all sorts, some even naughtier than you can ever imagine. There will even be one that shows you riding a donkey on the top of Eiffel tower. It´s simply data.
