Digital Photos Act as Unique Fingerprints in Finding Criminals with Digital Cameras
“The colors and brightness levels that we can physically see in our digital pictures are created by a demosaicing software, which is custom built for every camera model due to each camera’s individual specs and subtle differences. Because of this, a certain camera model will generate distinct pixels—and unique relationships between its neighboring pixels—which can pinpoint the exact make and model of the camera. Knowing this information could greatly help forensics teams since each digital camera has a shelf life of about 18 months, which would significantly narrow the pool of where and when it was sold. Although it is not perfect, early tests have shown this technique has proven to be 90 percent accurate, which is still an A in my book!”
