Guidelines on Mobile Device Forensics

Abstract: Mobile device forensics is the science of recovering digital evidence from a mobile device under forensically sound conditions using accepted methods. Mobile device forensics is an evolving specialty in the field of digital forensics. This guide attempts to bridge the gap by providing an indepth look into mobile devices and explaining technologies involved and their relationship to forensic procedures. This document covers mobile devices with features beyond simple voice communication and text messaging capabilities. This guide also discusses procedures for the validation, preservation, acquisition, examination, analysis, and reporting of digital information.

Using Extended File Information (EXIF) File Headers in Digital Evidence Analysis

Abstract: An obstacle in any Child Pornography (CP) investigation is the investigator’s ability to determine whether the pictures in question have been altered. Because of the court ruling in Ashcroft v. Free Speech, many agents are asked on the stand if they can prove the pictures they recovered were altered in any way. If the picture doesn’t match any known CP hashes, then it can be very difficult to prove they are untouched. One way an investigator may be able determine if a picture is authentic is through extraction of metadata. In the case of digital pictures, they may contain EXIF headers that can help the investigator to verify the authenticity of a picture.

Advancing Regulatory Science With Computational Modeling for Medical Devices at the FDA's Office of Science and Engineering Laboratories

Abstract: Protecting and promoting public health is the mission of the U.S. Food and Drug Administration (FDA). FDA's Center for Devices and Radiological Health (CDRH), which regulates medical devices marketed in the U.S., envisions itself as the world's leader in medical device innovation and regulatory science-the development of new methods, standards, and approaches to assess the safety, efficacy, quality, and performance of medical devices. Traditionally, bench testing, animal studies, and clinical trials have been the main sources of evidence for getting medical devices on the market in the U.S. In recent years, however, computational modeling has become an increasingly powerful tool for evaluating medical devices, complementing bench, animal and clinical methods. Moreover, computational modeling methods are increasingly being used within software platforms, serving as clinical decision support tools, and are being embedded in medical devices. Because of its reach and huge potential, computational modeling has been identified as a priority by CDRH, and indeed by FDA's leadership. Therefore, the Office of Science and Engineering Laboratories (OSEL)-the research arm of CDRH-has committed significant resources to transforming computational modeling from a valuable scientific tool to a valuable regulatory tool, and developing mechanisms to rely more on digital evidence in place of other evidence. This article introduces the role of computational modeling for medical devices, describes OSEL's ongoing research, and overviews how evidence from computational modeling (i.e., digital evidence) has been used in regulatory submissions by industry to CDRH in recent years. It concludes by discussing the potential future role for computational modeling and digital evidence in medical devices.

Cybercrime: Investigating High-Technology Computer Crime

Abstract: This innovative text provides an excellent introduction to technology-assisted crime and the basics of investigating such crime, from the criminal justice perspective. It presents clear, concise explanations for students and professionals, who need not be technically proficient to find the material easy-to-understand and practical. The book begins by identifying and defining the most prevalent and emerging high-technology crimes - and exploring their history, their original methods of commission, and their current methods of commission. Then it delineates the requisite procedural issues associated with investigating technology-assisted crime. In addition, the text provides a basic introduction to computer forensics, explores legal issues in the admission of digital evidence, and then examines the future of high-technology crime, including legal responses. Chapters of this title include review questions, further reading, online resources.
