Glitter nail polish can keep your data private (no, really)

Protecting your data when you travel is simpler than you might imagine. Three words: Glitter nail polish. It works! At a security congress on Monday security researchers Eric Michaud and Ryan Lackey demonstrated the power of nail polish. People can now be more vigilant with their devices, and knoiw when they have been physically tampered with and possibly compromised. 

THe way it works is that glitter nail polish has what is effectively a random pattern once applied. Once painted over stickers or onto screws in a port, it is impossible to replicate if broken. However, reapplication of the same paint might be enough to fool the humnan eye. Michaud and Lackey recommend taking photos of the laptop with the seals applied, and then rechecking them. Even very small differences - an adjusted screw, or glitter nail polish that follows a different pattern - will be evident. Et voila! This is a sure, if comparably labourious, way of keeping data secure. Given the current global situation, more and more remedies like this are needed.
