摘要

成像传感器(如CCD、CMOS)的图案噪声是一种类噪声的扩频信号，主要由光响应非均匀性(PRNU)噪声组成。由于每个相机都有一个独特的PRNU，因此PRNU成为一种流行的源相机识别指纹。目前的指纹都是基于一个色带构建的。为了更好地反映相机的内在特征，本作品探索了基于图像的三个色带构建指纹的方法。

Building fingerprints with information from three color bands for source camera identification

The imaging sensor (e.g., CCD, CMOS) pattern noise is a noise-like spread-spectrum signal that mainly consists of the photo-response non-uniformity (PRNU) noise. Since each camera has a unique PRNU, the PRNU becomes a popular fingerprint for source camera identification. Current fingerprints are built based on one color band. To better reflect the intrinsic characteristics of the camera, this work explores the way to build fingerprints based on three color bands of an image.
