Electrical & Computer Engineering and Computer Science Faculty Publications
With the widespread integration of AI in everyday and critical technologies, it seems inevitable to witness increasing instances of failure in AI systems. In such cases, there arises a need for technical investigations that produce legally acceptable and scientifically indisputable findings and conclusions on the causes of such failures. Inspired by the domain of cyber forensics, this paper introduces the need for the establishment of AI Forensics as a new discipline under AI safety. Furthermore, we propose a taxonomy of the subfields under this discipline, and present a discussion on the foundational challenges that lay ahead of this new research …
Catching Killers With Consumer Genetic Information, Angela Hackstadt
Catching Killers With Consumer Genetic Information, Angela Hackstadt
University Libraries Faculty Scholarship
In April 2018, Joseph James D'Angelo was arrested as a suspect in the Golden State Killer case. DNA evidence collected at a 1980 crime scene finally shed light on the murderer's identity in early 2018 when investigators turned to GEDMatch, a service that allows users to upload and share DNA data obtained from consumer genetic tests. Consumer genetic testing, DNA collection, and familial DNA searching all raise ethical and privacy concerns. If investigators are using genetic genealogy to solve cold cases, where does that leave consumers?
Haplotype Analysis For Irish Ancestry, Heather Miller Coyle, Robert Whiting
Haplotype Analysis For Irish Ancestry, Heather Miller Coyle, Robert Whiting
Forensic Science Publications
Forensic haplotype analysis of the male Y chromosome is currently used to establish the number of male donors in sexual assaults, the number of male bleeders in blood pattern analysis, and for ancestry correlation to genetic founder populations in biogeographic studies. In forensic laboratory applications, its primary use is for DNA profile generation with trace amounts of male DNA in the presence of excess female DNA (e.g. spermatozoa identification, male component of fingernail scrapings). Our study supports the potential use of the Y chromosome in a “dragnet” approach (most haplotypes are unique) similar to that described by Kayser in 2017 …

A deeper understanding of these various concepts will help progress the field. To achieve this goal, we conducted a survey which received 70 …
The Development And Use Of Computational Tools In Forensic Science, Dennis E. Slice
The Development And Use Of Computational Tools In Forensic Science, Dennis E. Slice
Human Biology Open Access Pre-Prints
Modern computational resources make available a rich toolkit of statistical methods that can be applied to forensic questions. This toolkit is built on the foundation of statistical developments dating back to the 19th century. To fully and effectively exploit these developments, both the makers and users of software must be keenly aware of the quality, i.e., the accuracy and precision, of the data being modeled or analyzed, and end-users must be sufficiently familiar with the underlying theory to understand the process and results of any analysis or software they use. This is especially important for medico-legal personnel who might be …
Correcting Forensic Dna Errors, Greg Hampikian
Correcting Forensic Dna Errors, Greg Hampikian
Biology Faculty Publications and Presentations
DNA mixture interpretation can produce opposing conclusions by qualified forensic analysts, even within the same laboratory. The long-delayed publication of the National Institutes of Standards and Technology (NIST) study of 109 North American crime laboratories in this journal demonstrates this most clearly. This latest study supports earlier work that shows common methods such as the Combined Probability of Inclusion (CPI) have wrongly included innocent people as contributors to DNA mixtures.The 2016 President’s Council of Advisors on Science and Technology report concluded,“In summary, the interpretation of complex DNA mixtures with the CPI statistic has been an inadequately specified—and thus inappropriately subjective—method. …
Analysis Of Error Within Forensic Measurements And Photogrammetry Programs, Amy Douglas
Analysis Of Error Within Forensic Measurements And Photogrammetry Programs, Amy Douglas
Honors Theses
Digital images and photography have been considered commonplace in forensic science since the late 1990’s. Photogrammetry is a tool used in forensic science to measure objects within photographs that contain a scale or programs that are able to measure items in 3D images. Items at crime scenes often need to be measured and forensic scientists may not know what the best option is for their situation. This research will be conducted to show which type of measurement technique is most accurate, calculated against NIST traceable measurements, at various sizes of objects. The measurement techniques that will be tested are standard, …
On Efficiency Of Artifact Lookup Strategies In Digital Forensics, Lorenz Liebler, Patrick Schmitt, Harald Baier, Frank Breitinger
On Efficiency Of Artifact Lookup Strategies In Digital Forensics, Lorenz Liebler, Patrick Schmitt, Harald Baier, Frank Breitinger
Electrical & Computer Engineering and Computer Science Faculty Publications
In recent years different strategies have been proposed to handle the problem of ever-growing digital forensic databases. One concept to deal with this data overload is data reduction, which essentially means to separate the wheat from the chaff, e.g., to filter in forensically relevant data. A prominent technique in the context of data reduction are hash-based solutions. Data reduction is achieved because hash values (of possibly large data input) are much smaller than the original input. Today's approaches of storing hash-based data fragments reach from large scale multithreaded databases to simple Bloom filter representations. One main focus was put on …
Determination Of Vehicle Speed From Recorded Video Using Reverse Projection Photogrammetry And File Metadata, Brandon Epstein, Bryce Westlake
Determination Of Vehicle Speed From Recorded Video Using Reverse Projection Photogrammetry And File Metadata, Brandon Epstein, Bryce Westlake
Faculty Publications
The prevalence of security and in‐car video has increased the number of motor vehicle accidents captured on digital video. However, inconsistencies in how to accurately determine time and distance for vehicle speed has led to examinations with varying results. A potential solution for calculating time intervals is to use frame timing contained within many digital video file's metadata, recorded with 0.000001 sec precision. This paper examines a fatal motor vehicle accident where frame timing information was used with distance measurements from reverse projection photogrammetry to calculate vehicle speed. A margin of error was then calculated based on the accuracy in …

Frameup: An Incriminatory Attack On Storj: A Peer To Peer Blockchain Enabled Distributed Storage System, Xiaolu Zhang, Justin Grannis, Ibrahim Baggili, Nicole Lang Beebe
Electrical & Computer Engineering and Computer Science Faculty Publications
In this work we present a primary account of frameup, an incriminatory attack made possible because of existing implementations in distributed peer to peer storage. The frameup attack shows that an adversary has the ability to store unencrypted data on the hard drives of people renting out their hard drive space. This is important to forensic examiners as it opens the door for possibly framing an innocent victim. Our work employs Storj as an example technology, due to its popularity and market size. Storj is a blockchain enabled system that allows people to rent out their hard drive space …
The Potential Interference Of Body Products And Substrates To The Identification Of Ignitable Liquid Residues On Worn Clothing, Gina Guerrera, Erika Chen, Robert Powers, Brooke Weinger Kammrath
The Potential Interference Of Body Products And Substrates To The Identification Of Ignitable Liquid Residues On Worn Clothing, Gina Guerrera, Erika Chen, Robert Powers, Brooke Weinger Kammrath
Forensic Science Publications
The question of whether deposits on clothing as well as their chemical composition are being mistaken for ignitable fluids is a concern for forensic analysts. Body products and oil secretions can have similar chemical profiles to ignitable liquid residues (ILRs) as a result of comparable chemical compounds that may be found in both sources. This study investigated whether substrates of unworn and worn clothing, with endogenous body secretions and body products could interfere with ILR analysis. Sample extraction was completed by passive headspace concentration with activated charcoal strips (ACS) and desorption with carbon disulfide followed by analysis with gas chromatography-mass …

For those investigating cases of Child Sexual Abuse Material (CSAM), there is the potential harm of experiencing trauma after illicit content exposure over a period of time. Research has shown that those working on such cases can experience psychological distress. As a result, there has been a greater effort to create and implement technologies that reduce exposure to CSAM. However, not much work has explored gathering insight regarding the functionality, effectiveness, accuracy, and importance of digital forensic tools and data science technologies from practitioners who use them. This study focused specifically on examining the value practitioners give to the tools …

Forensic Science Publications
A single focus optical tweezer is formed when a laser beam is launched through a high numerical aperture immersion objective. This objective focuses the beam down to a diffraction-limited spot, which creates an optical trap where cells suspended in aqueous solutions can be held fixed. Spermatozoa, an often probative cell type in forensic investigations, can be captured inside this optical trap and dragged one by one across millimeter-length distances in order to create a cluster of cells which can be subsequently drawn up into a capillary for collection. Sperm cells are then ejected onto a sterile cover slip, counted, and …

Rethinking Digital Forensics, Andrew Jones, Stilianos Vidalis
Research outputs 2014 to 2021
In the modern socially-driven, knowledge-based virtual computing environment in which organisations are operating, the current digital forensics tools and practices can no longer meet the need for scientific rigour. There has been an exponential increase in the complexity of the networks with the rise of the Internet of Things, cloud technologies and fog computing altering business operations and models. Adding to the problem are the increased capacity of storage devices and the increased diversity of devices that are attached to networks, operating autonomously. We argue that the laws and standards that have been written, the processes, procedures and tools that …

Virtual Reality (VR) has become a reality. With the technology's increased use cases, comes its misuse. Malware affecting the Virtual Environment (VE) may prevent an investigator from ascertaining virtual information from a physical scene, or from traditional “dead” analysis. Following the trend of antiforensics, evidence of an attack may only be found in memory, along with many other volatile data points. Our work provides the primary account for the memory forensics of Immersive VR systems, and in specific the HTC Vive. Our approach is capable of reconstituting artifacts from memory that are relevant to the VE, and is also capable …
