Forensic specialists can now pinpoint the exact make and model of a camera simply by analysing the pixels in digital photos. This technique would be useful in the future for tracking down criminals, such as kidnappers who’ve leaked photos of their hostages to the media. Read on to find out how it works.
The fundamental proposition of consumer technology is as follows: the closer we are to using the gadgets featured in the last 10 years of crappy spy thrillers and action movies, the more progress we’ve made. That’s how the Surface came to be, and how we’ve ended up with the fingerprint-grabbing, light-sensing LCD panel. AU Optronics has developed systems that can handle both without interfering with a panel’s display capabilities. While this tech is not likely to quickly replace the dirt-cheap light sensors that manage screen brightness now, LCD fingerprinting could add an interesting security layer for increasingly common touchscreen devices, among other things.
