Feature-Based Camera Model Identification Works in Practice

摘要: Feature-based camera model identification plays an important role in the toolbox for image source identification. It enables forensic investigator to discover probable employed acquire under investigation. However, little is known about performance on large sets of cameras that include multiple devices same model. Following process a investigation, this paper tackles questions application feature-based real world scenarios. More than 9,000 images were acquired controlled conditions using 44 digital 12 different models. This forms basis in-depth analysis a) intra-camera similarity, b) number required and training method, c) influence settings. All experiments suggest: works practice provides reliable results even if only one device each investigation available investigator.
