Identification Technologies for Digital Cameras Using Image Sensor’s Noise


It is known that DNA and finger print are useful for identifying a human. A camera also has unique noise and it is included in an image taken by the camera though it is very small. By using the unique noise, we can know which camera took an image and which part was falsified in an image. In this research project, we aim to realize methods to extract the unique noise precisely in an image and their applications.
