TL;DR: A novel methodical evaluation of 21 state-of-the-art PRNU estimation/enhancement techniques that have been proposed in the literature in various frameworks and are extensively demonstrated over a large-scale experiment to conclude this case-sensitive study.
Abstract: Extracting a fingerprint of a digital camera has fertile applications in image forensics, such as source camera identification and image authentication. In the last decade, photo response non_uniformity (PRNU) has been well established as a reliable unique fingerprint of digital imaging devices. The PRNU noise appears in every image as a very weak signal, and its reliable estimation is crucial for the success rate of the forensic application. In this paper, we present a novel methodical evaluation of 21 state-of-the-art PRNU estimation/enhancement techniques that have been proposed in the literature in various frameworks. The techniques are classified and systematically compared based on their role/stage in the PRNU estimation procedure, manifesting their intrinsic impacts. The performance of each technique is extensively demonstrated over a large-scale experiment to conclude this case-sensitive study. The experiments have been conducted on our created database and a public image database, the “Dresden image database.”

TL;DR: Various forensics tools, law challenges for the forensics examiner such as the Fourth Amendment, and chain of custody issues that a forensics expert could endure while gathering information from mobile devices are described.
Abstract: The paper deals with the various types of mobile devices that have large storage capacities and the challenges for forensics experts in gathering information from the devices for use in criminal investigations. The paper describes various forensics tools, law challenges for the forensics examiner such as the Fourth Amendment, and chain of custody issues that a forensics expert could endure while gathering information from mobile devices. The reader will learn about the struggles to effectively manage digital evidence obtained from such mobile devices and some of the issues in using some of the more popular tools on the market to conduct forensics. Finally, the reader will conclude the various challenges that could occur for the forensics examiner in conducting investigations until law disputes are resolved and the maturity and standardization of software tools develop.
