If you worry about your digital devices being hacked, you may soon have another thing to worry about. Specifically, your tattoo.
If wearable tech that's painted on you like a removable tattoo becomes widely accepted, it may vulnerable to hackers. These devices are comparable to a fitness tracker you wear on your wrist, only it's stuck on your skin.
A company called Chaotic Moon is developing the Tech Tats technology. It could have numerous uses, and could take away the ick factor of swallowing a sensor or having a device implanted in your body.
Ideally, tech tattoos will be able to monitor your health, like your heart rate, body temperature, or detect if you're getting sick. They may also have everyday uses, like providing light when you're in a dark place, or give you easy access to your ATM without needing a card or a PIN.
Tech Tats work in conjunction with your smartphone. They transmit information using an Atmel micro-controller and an integrated Bluetooth low-energy (BLE) micro-controller.
While the Tech Tats technology is being developed, these painted-on devices are already raising concerns about hackers breaking into your tats. A company spokesperson says, "the data is only released via a one-to-one connection to an approved Bluetooth device, [so] the hacker would then have to infiltrate the system."
To prevent that, Chaotic Moon is working on a security system similar to those used by EMV credit cards. Instead of having all your personal information stored onto a card's black strip, EMV cards create a unique code for each of your transactions. If a hacker steals that transaction code, they can't do anything with it since that code won't be used again.
No word yet when, or if Tech Tats will become commercially available. (Want to see how Tech Tats work? Check out this video.)
