A Case Study Of The Challenges Of Cyber Forensics Analysis Of Digital Evidence In A Child Pornography Trial, Richard Boddington

Annual ADFSL Conference on Digital Forensics, Security and Law

Perfunctory case analysis, lack of evidence validation, and an inability or unwillingness to present understandable analysis reports adversely affect the outcome course of legal trials reliant on digital evidence. These issues have serious consequences for defendants facing heavy penalties or imprisonment yet expect their defence counsel to have clear understanding of the evidence. Poorly reasoned, validated and presented digital evidence can result in conviction of the innocent as well as acquittal of the guilty. A possession of child pornography Case Study highlights the issues that appear to plague case analysis and presentation of digital evidence relied on in these odious …

After Five Years Of E-Discovery Missteps: Sanctions Or Safe Harbor?, Milton Luoma, Vicki Luoma

Annual ADFSL Conference on Digital Forensics, Security and Law

In 2003 the Zubulake case became the catalyst of change in the world of e-discovery. In that case Judge Shira Scheindlin of the United States District Court for the Southern District of New York set guidelines for e-discovery that served as the basis for amending the Federal Rules of Civil Procedure (FRCP) in December 2006. The amendments incorporated a number of concepts that were described by Judge Scheindlin in the Zubulake case. ( Zubulake v. UBS Warburg LLC, 2003) Since the Zubulake case and the FRCP amendments, numerous cases have interpreted these rules changes, but one of the main points …

Multi-Parameter Sensitivity Analysis Of A Bayesian Network From A Digital Forensic Investigation, Richard E. Overill, Echo P. Zhang, Kam-Pui Chow

Annual ADFSL Conference on Digital Forensics, Security and Law

A multi-parameter sensitivity analysis of a Bayesian network (BN) used in the digital forensic investigation of the Yahoo! email case has been performed using the principle of ‘steepest gradient’ in the parameter space of the conditional probabilities. This procedure delivers a more reliable result for the dependence of the posterior probability of the BN on the values used to populate the conditional probability tables (CPTs) of the BN. As such, this work extends our previous studies using singleparameter sensitivity analyses of BNs, with the overall aim of more deeply understanding the indicative use of BNs within the digital forensic and …

Cloud Forensics Investigation: Tracing Infringing Sharing Of Copyrighted Content In Cloud, Yi-Jun He, Echo P. Zhang, Lucas C.K. Hui, Siu Ming Yiu, K.P. Chow

Annual ADFSL Conference on Digital Forensics, Security and Law

Cloud Computing is becoming a significant technology trend nowadays, but its abrupt rise also creates a brand new front for cybercrime investigation with various challenges. One of the challenges is to track down infringing sharing of copyrighted content in cloud. To solve this problem, we study a typical type of content sharing technologies in cloud computing, analyze the challenges that the new technologies bring to forensics, formalize a procedure to get digital evidences and obtain analytical results based on the evidences to track down illegal uploader. Furthermore, we propose a reasoning model based on the probability distribution in a Bayesian …

Ipad2 Logical Acquisition: Automated Or Manual Examination?, Somaya Ali, Sumaya Alhosani, Farah Alzarooni, Ibrahim Baggili

Annual ADFSL Conference on Digital Forensics, Security and Law

Due to their usage increase worldwide, iPads are on the path of becoming key sources of digital evidence in criminal investigations. This research investigated the logical backup acquisition and examination of the iPad2 device using the Apple iTunes backup utility while manually examining the backup data (manual examination) and automatically parsing the backup data (Lantern software - automated examination). The results indicate that a manual examination of the logical backup structure from iTunes reveals more digital evidence, especially if installed application data is required for an investigation. However, the researchers note that if a quick triage is needed of an …

A Fuzzy Hashing Approach Based On Random Sequences And Hamming Distance, Frank Breitinger, Harald Baier

Annual ADFSL Conference on Digital Forensics, Security and Law

Hash functions are well-known methods in computer science to map arbitrary large input to bit strings of a fixed length that serve as unique input identifier/fingerprints. A key property of cryptographic hash functions is that even if only one bit of the input is changed the output behaves pseudo randomly and therefore similar files cannot be identified. However, in the area of computer forensics it is also necessary to find similar files (e.g. different versions of a file), wherefore we need a similarity preserving hash function also called fuzzy hash function. In this paper we present a new approach for …

These communication capabilities have, unfortunately, been exploited by people to plan and commit a variety of criminal activities. In an attempt to cover the digital tracks of these unlawful undertakings, anti-forensic techniques, such as steganography, …

Double-Compressed Jpeg Detection In A Steganalysis System, Jennifer L. Davidson, Pooja Parajape

Annual ADFSL Conference on Digital Forensics, Security and Law

The detection of hidden messages in JPEG images is a growing concern. Current detection of JPEG stego images must include detection of double compression: a JPEG image is double compressed if it has been compressed with one quality factor, uncompressed, and then re-compressed with a different quality factor. When detection of double compression is not included, erroneous detection rates are very high. The main contribution of this paper is to present an efficient double-compression detection algorithm that has relatively lower dimensionality of features and relatively lower computational time for the detection part, than current comparative classifiers. We use a model-based …

Toward Alignment Between Communities Of Practice And Knowledge-Based Decision Support, Jason Nichols, David Biros, Mark Weiser

Annual ADFSL Conference on Digital Forensics, Security and Law

The National Repository of Digital Forensics Information (NRDFI) is a knowledge repository for law enforcement digital forensics investigators (LEDFI). Over six years, the NRDFI has undertaken significant design revisions in order to more closely align the architecture of the system with theory addressing motivation to share knowledge and communication within ego-centric groups and communities of practice. These revisions have been met with minimal change in usage patterns by LEDFI community members, calling into question the applicability of relevant theory when the domain for knowledge sharing activities expands beyond the confines of an individual organization to a community of practice. When …

A Proposal For Incorporating Programming Blunder As Important Evidence In Abstraction-Filtration-Comparison Test, P. Vinod Bhattathiripad

Annual ADFSL Conference on Digital Forensics, Security and Law

This paper investigates an unexplored concept in Cyber Forensics, namely, a Programming Blunder. Programming Blunder is identified as a variable or a code segment or a field in a database table, which is hardly used or executed in the context of the application or the user’s functionality. Blunder genes can be found in many parts of any program. It is the contention of this paper that this phenomenon of blunders needs to be studied systematically from its very genetic origins to their surface realizations in contrast to bugs and flaws, especially in view of their importance in software copyright infringement …

Update On The State Of The Science Of Digital Evidence Examination, Fred Cohen

Annual ADFSL Conference on Digital Forensics, Security and Law

This paper updates previous work on the level of consensus in foundational elements of digital evidence examination. Significant consensus is found present only after definitions are made explicit, suggesting that, while there is a scientific agreement around some of the basic notions identified, the use of a common language is lacking.

Keywords: Digital forensics examination, terminology, scientific methodology, testability, validation, classification, scientific consensus

A Multilevel Analysis Of County And State Variation In The Severity Of Sentences Imposed In Large Urban Courts, Kimberly Helen Martin

Dissertations

This study explored the structural sources behind variability in the sentences applied to felons convicted in state courts located across the U.S. Multilevel regression models were used to explore whether various state and county-level attributes help to account for why defendants experience a significantly higher probability of incarceration versus probation in certain jurisdictions. Drawing upon a broad theoretical landscape, the analyses test several hypotheses derived from macro level theories of social control which predict that that the legal and organizational culture of courts, and the socioeconomic and political attributes of the communities they serve, influence sentencing outcomes. This study sought …

This qualitative study explored perceptions of community-based advocates in Jefferson County, Colorado and their experience assisting victims of intimate partner violence against women. Open-ended interview questionnaires were collected from community-based advocates and used to derive the perceptions community-based advocates hold with regard to access to community resources, ability to establish social support, improve quality of life, and ultimately reduce re-abuse. Results of these perceptions were combined with and compared to previous secondary research by Deborah Bybee and Cris Sullivan. This research of victims' perceived effectiveness combined with data collected from advocates' perceived effectiveness allowed for further insight into intimate partner …

An Examination Of Perceived Stress Levels And Coping Styles Among Rural Law Enforcement Officers, Marcos Luis Misis

Dissertations

Policing is a very stressful job. Despite the extensive body of research on police stress, the majority of studies have focused solely on officers within urban police departments. Research on stress within rural law enforcement departments is virtually non-existent even though the majority of police agencies in America serve towns and areas under 50,000 residents.

This study had four main goals: (1) to examine how work-related stress affects the levels of perceived stress, anxiety, and depression for rural law enforcement officers; (2) to explore the specific stressors affecting rural law enforcement officers; (3) to investigate how rural law enforcement officers …

HIM 1990-2015

After the calamitous and environmentally devastating occurrence of the Deepwater Horizon Oil Spill in the Gulf of Mexico in 2010, the sobering realities of the United States' failure to successfully protect its ocean waters have caused several modifications in policy, legislation, and overall direction ofthe entire nation. Although there has been a general shift towards ecological safety and away from the pursuit to drill, oil-drilling explorations have continued to take place in internationally. This research will focus on the future operations of Repsol YPF, S.A., a Spanish oil company stationed in Cuba, whose drilling ambitions have caused a myriad of …

Causes And Effects: An Examination Of Legislative Professionalism As An Independent And Dependent Variable In State Legislatures, Alexandra Edelstein

Mahurin Honors College Capstone Experience/Thesis Projects

Professionalism’s dual role as an independent and dependent variable makes the impact of its institutional characteristics on legislator attitudes and behavior important to understand. Professionalism affects the behavior and attitudes of the same legislators who control the strength of its characteristics through the policies they create. In this two-part study, I measure the influence of personal and contextual factors on legislator attitudes towards the adequacy of legislative professionalism in state legislatures. I then identify the effects of legislative professionalism on legislator allocation of time. I find that political (party) and personal (ambition) factors play the primary roles in shaping how …
