Cat Detect (Computer Activity Timeline Detection): A Tool For Detecting Inconsistency In Computer Activity Timelines, Andrew Marrington, Ibrahim Baggili, George Mohay, Andrew Clark
Electrical & Computer Engineering and Computer Science Faculty Publications
The construction of timelines of computer activity is a part of many digital investigations. These timelines of events are composed of traces of historical activity drawn from system logs and potentially from evidence of events found in the computer file system. A potential problem with the use of such information is that some of it may be inconsistent and contradictory thus compromising its value. This work introduces a software tool (CAT Detect) for the detection of inconsistency within timelines of computer activity. We examine the impact of deliberate tampering through experiments conducted with our prototype software tool. Based on the …

Demonstration: Real-Time Semantic Analysis Of Sensor Streams, Harshal Kamlesh Patni, Cory Andrew Henson, Michael Cooney, Amit P. Sheth, Krishnaprasad Thirunarayan
Kno.e.sis Publications
The emergence of dynamic information sources - including sensor networks - has led to large streams of real-time data on the Web. Research studies suggest, these dynamic networks have created more data in the last three years than in the entire history of civilization, and this trend will only increase in the coming years. With this coming data explosion, real-time analytics software must either adapt or die. This paper focuses on the task of integrating and analyzing multiple heterogeneous streams of sensor data with the goal of creating meaningful abstractions, or features. These features are then temporally aggregated into feature …

Column: File Cabinet Forensics, Simson Garfinkel
Journal of Digital Forensics, Security and Law
Researchers can spend their time reverse engineering, performing reverse analysis, or making substantive contributions to digital forensics science. Although work in all of these areas is important, it is the scientific breakthroughs that are the most critical for addressing the challenges that we face. Reverse Engineering is the traditional bread-and-butter of digital forensics research. Companies like Microsoft and Apple deliver computational artifacts (operating systems, applications and phones) to the commercial market. These artifacts are bought and used by billions. Some have evil intent, and (if society is lucky), the computers end up in the hands of law enforcement. Unfortunately the …

Column: Putting The Science In Digital Forensics, Fred Cohen
Journal of Digital Forensics, Security and Law
In a recent study, digital forensics was found to lack a consensus around even the most basis notions and terminology of the field. To quote: “These two preliminary studies individually suggest that (1) scientific consensus in the area of digital forensic evidence examination is lacking in the broad sense, but that different groups within that overall community may have limited consensus around areas in which they have special expertise, and (2) that the current peerreviewed publication process is not acting to bring about the sorts of elements typically found in the advancement of a science toward such a consensus. ... …

Technology Corner: Internet Packet Sniffers, Nick V. Flor, Kenneth Guillory
Journal of Digital Forensics, Security and Law
The best way to understand an internet packet sniffer, hereafter “packet sniffer”, is by analogy with a wiretap. A wiretap is a piece of hardware that allows a person to eavesdrop on phone conversations over a telephone network. Similarly, a packet sniffer is a piece of software that allows a person to eavesdrop on computer communications over the internet. A packet sniffer can be used as a diagnostic tool by network administrators or as a spying tool by hackers who can use it to steal passwords and other private information from computer users. Whether you are a network administrator or …
Sampling: Making Electronic Discovery More Cost Effective, Milton Luoma, Vicki Luoma
Sampling: Making Electronic Discovery More Cost Effective, Milton Luoma, Vicki Luoma
Journal of Digital Forensics, Security and Law
With the huge volumes of electronic data subject to discovery in virtually every instance of litigation, time and costs of conducting discovery have become exceedingly important when litigants plan their discovery strategies. Rather than incurring the costs of having lawyers review every document produced in response to a discovery request in search of relevant evidence, a cost effective strategy for document review planning is to use statistical sampling of the database of documents to determine the likelihood of finding relevant evidence by reviewing additional documents. This paper reviews and discusses how sampling can be used to make document review more …

Developing A Forensic Continuous Audit Model, Grover S. Kearns, Katherine J. Barker, Stephen P. Danese
Journal of Digital Forensics, Security and Law
Despite increased attention to internal controls and risk assessment, traditional audit approaches do not seem to be highly effective in uncovering the majority of frauds. Less than 20 percent of all occupational frauds are uncovered by auditors. Forensic accounting has recognized the need for automated approaches to fraud analysis yet research has not examined the benefits of forensic continuous auditing as a method to detect and deter corporate fraud. The purpose of this paper is to show how such an approach is possible. A model is presented that supports the acceptance of forensic continuous auditing by auditors and management as …

Technology Corner: Virtual Crime Scene Reconstruction: The Basics Of 3d Modeling, Nick V. Flor
Journal of Digital Forensics, Security and Law
Digital crime scenes take place in the context of physical crime scenes. Virtual crime scene reconstruction is an activity where investigators create a 3- dimensional (3-D) model of an actual crime scene for the purpose of determining the events that lead to the crime. While virtual crime scene reconstruction is currently used for analyzing physical scenes, it can also help investigators visualize and explore ways digital media could have been used to perpetrate a crime. In this technology corner we explore one of the technologies underlying virtual crime scene reconstruction: 3-D modeling.

Investigating Modern Communication Technologies: The Effect Of Internet-Based Communication Technologies On The Investigation Process, Matthew Simon, Jill Slay
Journal of Digital Forensics, Security and Law
Communication technologies are commonplace in modern society. For many years there were only a handful of communication technologies provided by large companies, namely the Public Switched Telephone Network (PSTN) and mobile telephony; these can be referred to as traditional communication technologies. Over the lifetime of traditional communication technologies has been little technological evolution and as such, law enforcement developed sound methods for investigating targets using them. With the advent of communication technologies that use the Internet – Internet-based or contemporary communication technologies – law enforcement are faced with many challenges. This paper discusses these challenges and their potential impact. It …

Making Memory: Techne, Technology, And The Refashioning Of Contemporary Memory, Kimberly Lacey
Making Memory: Techne, Technology, And The Refashioning Of Contemporary Memory, Kimberly Lacey
Wayne State University Dissertations
My dissertation answers two questions: Does the tension between interactive technologies and rhetoric re-shape the nature and relevance of the canon of memory? Do interactive technologies affect the ways we remember and persuade? I argue that my interpretation of techne suggests possibilities for the creation and production of new types of memory in combination with digital media. To interrogate this connection, I suggest three interpretations of the Greek concept, techne: as a process that is inherently productive; as a force that renegotiates contemporary sources of social power; and as a skill that balances expert knowledge with instrumentality. I explore …

The Potential Role Of Business Intelligence In Church Organizations, Charmaine Felder
Walden Dissertations and Doctoral Studies
Business intelligence (BI) involves transforming data into actionable information to make better business decisions that may help improve operations. Although businesses have experienced success with BI, how leaders of church organizations might be able to exploit the advantages of BI in church organizations remains largely unexplored. The purpose of the phenomenological study was to explore the perceptions of pastoral leaders concerning the potential usefulness of BI in church organizations. Conceptual support for the study was based on the premise that churches may also benefit from BI that helps improve decision making and organizational performance. Three research questions were used to …
Asset Reuse Of Images From A Repository, Deirdre Herman
Asset Reuse Of Images From A Repository, Deirdre Herman
Walden Dissertations and Doctoral Studies
According to Markus's theory of reuse, when digital repositories are deployed to collect and distribute organizational assets, they supposedly help ensure accountability, extend information exchange, and improve productivity. Such repositories require a large investment due to the continuing costs of hardware, software, user licenses, training, and technical support. The problem addressed in this study was the lack of evidence in the literature on whether users in fact reused enough digital assets in repositories to justify the investment. The objective of the study was to investigate the organizational value of repositories to better inform architectural, construction, software and other industries whether …
Real-Time Traffic Estimation Using Data Expansion, Roger Lederman, Laura Wynter
Real-Time Traffic Estimation Using Data Expansion, Roger Lederman, Laura Wynter
Research Collection School Of Computing and Information Systems
This paper presents a method for estimating missing real-time traffic volumes on a road network using both historical and real-time traffic data. The method was developed to address urban transportation networks where a non-negligible subset of the network links do not have real-time link volumes, and where that data is needed to populate other real-time traffic analytics. Computation is split between an offline calibration and a real-time estimation phase. The offline phase determines link-to-link splitting probabilities for traffic flow propagation that are subsequently used in real-time estimation. The real-time procedure uses current traffic data and is efficient enough to scale …
