Forget Face ID Scientists Fight Cybercrime With Photos

first_img I’ve watched enough CSI: Crime Scene Investigation to know that forensic scientists can trace a single bullet directly to the gun that shot it.Apparently, researchers at the University at Buffalo in New York are fans of Gil Grissom, too, because they developed similar technology for tracking photos to phones.The technique, to be presented at a conference in February, could lead to new ways of fighting cybercrime.“Like snowflakes, no two smartphones are the same,” lead study author Kui Ren said in a statement. “Each device, regardless of the manufacturer or make, can be identified through a pattern of microscopic imaging flaws that are present in every picture they take.”Mind. Blown.“It’s kind of like matching bullets to a gun,” he added, “only we’re matching photos to a smartphone camera.”Not yet ready for prime time, this technology is poised to become part of the authentication process, like a PIN or password.Centered around an obscure flaw in digital imaging called photo-response non-uniformity (PRNU), the paper describes how manufacturing imperfections create minuscule variations in each digital camera’s sensors.Not visible to the naked eye, this “systemic distortion,” or pattern noise, is unique to every individual shooter. Handy in digital forensic science, the method has not yet been applied to cybersecurity.Until now.The proposed system is quite simple: When registering with a bank or retailer, for instance, the customer provides a smartphone photo for reference. Then, during future purchases or withdrawals, they are asked to photograph two QR codes—presented on an ATM, cash register, or another screen.Using a mobile application, the customer sends the images back to the company, which scans them to measure the camera’s PRNU, look for forgeries, and approve (or deny) the transaction.Ren’s protocol can spot even the most advanced counterfeits, thanks to an embedded probe signal in the QR codes.The program boasts 99.5 percent accuracy in tests involving 16,000 images and a total of 40 different Galaxy Note 5 and iPhone 6s handsets.
