What does identification mean?

Answer 1

The phrase "identification defenses" is a bit hard to pin down, out of context. The most likely interpretation is, someone in some situation does not wish to be identified, and therefore has some kind of mechanism that conceals his or her identity (such as a mask, or a false name). But there are other possible meanings, depending upon context. It could also be part of someone's defense system that they have to identify people (possibly by the use of identification cards or passwords). I can also imagine a court case in which a person claims that he or she did not commit a particular crime and that he or she has not been correctly identified.
