A team led by Tobias Weyand, a senior software engineer at Google, was able to develop a very interesting (or scary, depending on your point of view) artificial intelligence system. This is because it can identify the places where you took your pictures without your having to say.
Called PlaNet, the simple system works: By identifying a photo, it analyzes pixel by pixel and compares its data with 90 million other indexed images that are stored in its databases. From then on, the software crosses your photo's references, details and patterns to identify where it was recorded, but with incredible precision.
