I saw a Youtube video on a group of people just release the lens from the camera body with ease. Therefore, shouldn't those camera company come out with another button, will only unlock the release button when confirm from screen after pressed?

Either in on or off mode, once the button is pressed, it will ask you on screen whether you confirm to unlock the release button. This feature can be deactivated so that those who does not need it, can ignore it (inside studio etc.) :think:

I take it you mean thieves stealing lenses from slung cameras? Because "releasing the lens from the camera body with ease" is a POSITIVE for most of us.
Add extra complexity to operation, extra hardware (actuators to lock/unlock), and possible change the design of mount? No thanks!

How about a firmware-only solution. A Safe Travel mode -- when the lens is released, the camera starts beeping, flashing and firing at full FPS to warn the user ;)

Yeah, that's about right. And the default password is either '0000' or the last 4 digits of the serial number - which one can only read once the lens is unmounted...

and also a index finger print activated shutter release button, memory card door, so no one can use the camera except the owner.

Use retina scanning from the evf on dslr. Then all functions will only be unlock else whoever steal the camera can forget about using it. Only can be reset by the manufacturer, best suits those high end bodies! ;p
