RFID – Radio Frequency IDentification

An RFID tag hidden under a label

An RFID tag is nothing more than a little chip attached to a paper-thin antenna. The chip's basic function is to store and transmit a small amount of information, usually just a unique identifier. What good is that? Well:


Though there hundreds of visionary and useful things you can do RFID, because they typically lack strong security controls there are serious risks that come with them too!


Don't underestimate how easy it would be to track and monitor people by the poorly-secured RFID tags they carry
(See online!)

Making RFID Safe

On the plus side again, RFID can help prevent infant abduction or hospital mixups.

RFID, like most technology, isn't something that can (or necessarily should) be stopped. Intstead, we need to harness and direct the technology to reduce the threat. To do this, we need to look at three risk aspects of RFID:

1. Poor authentication

One of the primary issues with RFID and the main thing that makes all the nightmare scenarios possible is that unsecured RFID broadcasts to anyone and everyone. For any implementation of RFID to be acceptable, the chips must be programmed only to speak to proper readers who authenticated themselves first.

For example, say you have a refrigerator that scans the food inside. When you put food inside, the fridge should program the food with a one-time code that makes it impossible for the chips in the packaging to respond to any other reader.

Think no one cares what the contents of your fridge are? Think again.

2. Poor (or no) encryption

Even after a chip authenticates a reader, if it sends the data out in the open, anyone else nearby (or not so nearby) can read it too. All communications between a chip and authenticated reader must be encrypted to prevent eavesdropping by others.

3. Use of Long-term RFID

Implantation is permanent. Passports are good for 10 years. Companies plan to replace UPC barcodes with RFID that will transmit ID codes for the life of the product (from creation to landfill and beyond).

Every RFID implementations will eventually be hacked by someone. All it takes is one person in the world to find a way to break the system and the security is no good anymore (like the millions and millions of pounds wasted with the UK passports). Secure implementations can slow it down or help, but the best defense is NO RFID.

I can't see implants ever making sense and you definitely want to be sure the products you wear and carry around can't be used to wirelessly communicate with the world around them.
