Really, the only way to ever achieve such an ends would be to have everyone's skeletal structure on record. It's easy to make yourself appear different without even using a mask (such as make up, wearing glasses, shaving/growing a beard, loosing/gaining weight), but bones never lie.I think its not helpful for security if one can't tell the identity of someone. the basis of security is to recognise someone to know who they are.
And then there is also the issue of knowing who someone is, but not knowing who they really are. Serial killers, for instance, are known for being likeable and charismatic people, and sometimes even hold higher positions in society. And someone like Jim Jones, who would have saw him leading a mass-suicide back when he was transcending racial barriers (he was, after all, the first white person in Indiana to adopt a black child)? Even our own Revoltingest employed a computer tech who turned out to be a mass-murdering psycho.
