Hat Tip: PetaPixel
It's been a very slow news week. The only photography related stories I've been interested in have all been announcements on new camera, lenses or related products.
Those stories I just post links to and publish them on Sunday.
PetaPixel has one today that I feel obligated to comment on: turns out that iPhone infrared camera that was recently released poses a security threat to anyone using a passcode protected item, like an ATM. Someone taking a picture of the buttons immediately after the buttons are used can easily tell which buttons were pressed due to the residual heat left on them.
it is also possible to get some idea as to the order the buttons were pressed based on how much residual heat remains. The hottest buttons were used last and the buttons that retain less heat were used earlier. This greatly reduces the amount of effort needed to determine the passcode used by the previous customer.
There is a fairly easy way to protect yourself from this threat, just rest your hand on the button panel while entering your code. This heats up the buttons evenly which prevents being able to determine which buttons were pressed.
