A number of features protect the security of the information. The difference between a regular passport and an electronic passport is that this has a chip in it. This is what it looks like. It has a little gold thing on it. Other than that, it's exactly the same.
The information that goes on the chip is exactly the same as the information that's already on page 2 of the passport, including the photo. Then the information is put on the chip and it's locked, and as part of that locking process, a digital signature is put on that chip that other countries will then be able to verify with the ICAO public key infrastructure to ensure that the information was put on once and hasn't been tampered with.
There are different kinds of RFIDs, radio frequency identification tags. The kind of card that is in this is a card that has to be read within 10 centimetres, and there's also what we call basic access control so you have to read this machine-readable zone on the passport and it has to be open. So you can't skim the information from it. We're quite confident that the information is protected once it's put on the chip, and that it can't be read and picked up by somebody who shouldn't be reading it.
