| Abstract(in English) | In recent years, a digital camera identification method based on image sensor noise has been proposed, and this method is expected to contribute to scientific criminal investigations. In this paper, we propose a computationally efficient and reliable digital camera identification method for scaled images based on the combination of scaling factor estimation using interpolation-related periodicity and camera identification using the clustered Photo Response Non-uniformity (PRNU) noise. First, we enhanced Gallagher's method [1] and significantly improved the accuracy of scaling factor estimation. Then, we conducted camera identification for each candidate scaling factor obtained during scaling factor estimation. Finally, we conducted experiments, which demonstrated that the proposed method could identify the source cameras of scaled images with high accuracy. |
