This is a modestly well solved problem.

When the tech of the design fails it is defended in the law.

Barcodes and other tags including electronic tags support other bits of the

"a mark required by law for official identification in disease control

An additional defense is the target alteration must be recorded
which makes tracking and prosecuting the bad guys easier.
