Device authentication using display device irregularity |
摘要 |
A device authentication server authenticates a remotely located device using data representing pixel irregularities of a display of the device. Since each display will deteriorate in a unique and randomized way, a unique mapping of pixel irregularities of a display of a device will be unique. By combining unique map of pixel irregularities of a display of the remotely located device, the device can be distinguished from similar devices when other attributes alone are insufficient to uniquely identify the device. |
