#TIL that the #IAEA uses something called a „COBRA seal“ to seal relevant objects against manipulation. One type of these seals works by using a multi-core optical cable. When the seal is locked a random number of cores are cut. This creates a unique optical pattern that can be verified simply by shining a light into the cable and can’t be recreated.
