Security experts have discovered a new secret weapon to ensure your laptop and other devices are not tampered with -- glitter nail polish.
Read full storyIt's the "Hair on the steering wheel" method.Nothing new really, ... Manufacturers of Electronic devices have done this for years to know if anyone tampered with internal electronics etc. Although the unique pattern of the glitter is a good idea.

Fact of the matter is that if anyone was really creative one could replace a RJ11 jack on an older laptop with built in modem and replace the 2 pin with a 4 pin and make a special link cable to plug between the RJ11 4-pin and the USB port of the COMPUTER and at the other end of the 4-pin RJ11 jack is the guts of say a 64GB USB stick hot glued in an area that fits. You then have a secret 64GB of storage that is externally internal...LOL

And unless they test this RJ11 jack to see if there is a USB device at the other end, it will get missed.

But this is an already known trick that I heard from a friend who sat in on a computer forensics seminar in which it was discussed that the state police had a search WARRANT to search a house knowing that specific data was downloaded there, and when they got there, they couldnt find the data. Then they went around testing phone jacks and found a dead jack. They then removed the coverplate and found this radioshack special thumb drive wired to a 4-pin phone jack, and the person got busted for the ILLEGAL data that was downloaded.If anybody has trouble with that link, read here:

Glitter nail polish new weapon to protect data

WASHINGTON: Security experts have discovered a new secret weapon to ensure your laptop and other devices are not tampered with -- glitter nail polish.

Security researchers Eric Michaud and Ryan Lackey said glitter nail polish can help people know when their machines have been PHYSICALLY tampered with and potentially compromised.

Physical tampering with machines is a growing problem. While drive encryption, strong passwords and software-based measures might keep causal thieves out, travelling offers many ways for prying eyes to physically compromise a laptop, Lackey and Michaud noted.

Many people affix tamper-proof seals over ports and screws but these seals can in fact be replicated or opened cleanly in minutes by anyone with EVEN minimal training, the researchers said during a presentation at the Chaos Communication Congress in Germany.

Glitter nail polish can create a seal that is impossible to copy. Once applied, it has what effectively is a random pattern. Once painted over screws or onto stickers placed over ports, it is difficult to replicate once broken, 'Wired' magazine reported.

Experts recommend using your smartphone to take a picture of the laptop with the seals applied before leaving it alone, taking another photo upon returning and using a software programme to shift rapidly between the two images to compare them.

Even very small differences -- a screw that is in a very slightly different position, or glitter nail polish that has a very slightly different pattern of sparkle will be evident.

Astronomers use a similar technique called blink comparison to detect small changes in the night sky, researchers said.
