Abstract

The focus of this paper is a review of a digital camera identification technique proposed by Lukas et al [1], and a modification of the denoising filter, allowing it to be used for raw sensor data. The approach of using raw sensor data allows analysis of the noise pattern separate from any artefacts introduced by on-board camera processing. We use this extension for investigating the reliability of the technique when using different lenses between the same camera and between cameras of the same manufacturer.

Keywords: digital forensic source identification sensor noise reference noise pattern
