Mining EXIF Data From Camera Phones
emeitner notes that folks at the ISC wrote scripts that harvested 15,291 images from Twitpic and analyzed the EXIF information. This reader adds, “While mining EXIF data from images is nothing new, how many people would allow this data to leave their cell phone if they knew what it contained? The source code for the scripts is also available from the article.” “399 images included the location of the camera at the time the image was taken, and 102 images included the name of the photographer. … The iPhone is including the most EXIF information among the images we found. … It not only includes the phone’s location, but also accelerometer data showing if the phone was moved at the time the picture was taken and the readout from the [built-]in compass showing in which direction the phone was pointed at the time.”
