Through VoIP, not only may Alice carry on a telephone conversation, but most …

The Revised 40 Principles For Software Inventions, Umakant Mishra

Umakant Mishra

Applying 40 Principles is one of the earliest and most popular techniques of TRIZ. There are no controversies on application of 40 principles by any of the TRIZ schools. Although they are fundamentally sound, there is some difficulty in applying those in software related problems. As they were originally developed for mechanical or technical problems, the meaning of many terms like 'thermal', 'aerodynamic', 'hydrodynamic', 'ultrasonic', 'infrared', 'temperature', 'liquid', 'gas' etc. are embarrassing in a software context.

This article reviews the 40 principles in the context of software industry and rephrases the principles and their applications to make them suitable for …

Paper Session V: Forensic Software Tools For Cell Phone Subscriber Identity Modules, Wayne Jansen, Rick Ayers

Cell phones and other handheld devices incorporating cell phone capabilities (e.g., smart phones) are ubiquitous. Besides placing calls, cell phones allow users to perform other tasks such as text messaging and phonebook entry management. When cell phones and cellular devices are involved in a crime or other incident, forensic specialists require tools that allow the proper retrieval and speedy examination of data present on the device. For devices conforming to the Global System for Mobile Communications (GSM) standards, certain data such as dialed numbers, text messages, and phonebook entries are maintained on a Subscriber Identity Module (SIM). This paper gives …

Paper Session V: Steganography And Terrorist Communications - Current Information And Trends - Tools, Analysis And Future Directions In Steganalysis In Context With Terrorists And Other Criminals, William Eyre, Marcus Rogers

Annual ADFSL Conference on Digital Forensics, Security and Law

In ancient times, users communicated using steganography, “…derived from the Greek words steganos, meaning ‘covered’, and graphein, meaning ‘to write.’” (Singh, 1999, p.5) Steganography facilitates secret, undetected communication. In modern times, in the context of the Global War on Terror, national intelligence and law enforcement agencies need tools to detect hidden information (steganography) in various types of media, most specifically to uncover the placement of hidden information in images. This paper will look at steganography in general terms, presenting the theory of some common steganographic techniques and touching on some theoretical work in steganography. Then a discussion of how to …

Paper Session Iv: Development And Delivery Of Coursework - The Legal/Regulatory/Policy Environment Of Cyberforensics, John W. Bagby, John C. Ruhnka

Annual ADFSL Conference on Digital Forensics, Security and Law

This paper describes a cyber-forensics course that integrates important public policy and legal issues as well as relevant forensic techniques. Cyber-forensics refers to the amalgam of multi-disciplinary activities involved in the identification, gathering, handling, custody, use and security of electronic files and records, involving expertise from the forensic domain, and which produces evidence useful in the proof of facts for both commercial and legal activities. The legal and regulatory environment in which electronic discovery takes place is of critical importance to cyber-forensics experts because the legal process imposes both constraints and opportunities for the effective use of evidence gathered through …

Paper Session Iii: Research Brief: A Curriculum For Teaching Information Technology Investigative Techniques For Auditors, Grover S. Kearns, Elizabeth V. Mulig

Annual ADFSL Conference on Digital Forensics, Security and Law

Recent prosecutions of highly publicized white-collar crimes combined with public outrage have resulted in heightened regulation and greater emphasis on systems of internal control. Because both white-collar and cybercrimes are usually perpetrated through computers, auditors’ knowledge of information technology (IT) is now more vital than ever. However, preserving digital evidence and investigative techniques, which can be essential to fraud examinations, are not skills frequently taught in accounting programs. Furthermore, many students are not instructed in the use of computer assisted auditing tools and techniques – applications that might uncover fraudulent activity. Only a limited number of university-level accounting classes provide …

Paper Session Ii: Forensic Scene Documentation Using Mobile Technology, Ibrahim Baggili

Annual ADFSL Conference on Digital Forensics, Security and Law

This paper outlines a framework for integrating forensic scene documentation with mobile technology. Currently there are no set standards for documenting a forensic scene. Nonetheless, there is a conceptual framework that forensic scientists and engineers use that includes note taking, scene sketches, photographs, video, and voice interview recordings. This conceptual framework will be the basis that a mobile forensic scene documentation software system is built on. A mobile software system for documenting a forensic scene may help in standardizing forensic scene documentation by regulating the data collection and documentation processes for various forensic disciplines.

Fedora: An Architecture For Complex Objects And Their Relationships, Carl Lagoze, Sandy Payette, Edwin Shin, Chris Wilper

Edwin Shin

The Fedora architecture is an extensible framework for the storage, management, and dissemination of complex objects and the relationships among them. Fedora accommodates the aggregation of local and distributed content into digital objects and the association of services with objects. This allows an object to have several accessible representations, some of them dynamically produced. The architecture includes a generic Resource Description Framework (RDF)-based relationship model that represents relationships among objects and their components. Queries against these relationships are supported by an RDF triple store. The architecture is implemented as a web service, with all aspects of the complex object architecture …

The 2006 Analysis Of Information Remaining On Disks Offered For Sale On The Second Hand Market, Andy Jones, Craig Valli, Iain Sutherland, Paula Thomas

Journal of Digital Forensics, Security and Law

All organisations, whether in the public or private sector, use computers for the storage and processing of information relating to their business or services, their employees and their customers. A large proportion of families and individuals in their homes now also use personal computers and, both intentionally and inadvertently, often store on those computers personal information. It is clear that most organisations and individuals continue to be unaware of the information that may be stored on the hard disks that the computers contain, and have not considered what may happen to the information after the disposal of the equipment.

A Forensic Log File Extraction Tool For Icq Instant Messaging Clients, Kim Morfitt, Craig Valli

Journal of Digital Forensics, Security and Law

Instant messenger programs such as ICQ are often used by hackers and criminals for illicit purposes and consequently the log files from such programs are of interest in a forensic investigation. This paper outlines research that has resulted in the development of a tool for the extraction of ICQ log file entries. Detailed reconstruction of data from log files was achieved with a number of different ICQ software. There are several limitations with the current design including timestamp information not adjusted for the time zone, data could be altered, and conversations must be manually reconstructed. Future research will aim to …

A Curriculum For Teaching Information Technology Investigative Techniques For Auditors, Grover S. Kearns

Journal of Digital Forensics, Security and Law

Recent prosecutions of highly publicized white-collar crimes combined with public outrage have resulted in heightened regulation of financial reporting and greater emphasis on systems of internal control. Because both white-collar and cybercrimes are usually perpetrated through computers, internal and external auditors’ knowledge of information technology (IT) is now more vital than ever. However, preserving digital evidence and investigative techniques, which can be essential to fraud examinations, are not skills frequently taught in accounting programs and instruction in the use of computer assisted auditing tools and techniques – applications that might uncover fraudulent activity – is limited.

Electronic Data Discovery: Integrating Due Process Into Cyber Forensic Practice, John W. Bagby, John C. Ruhnka

Journal of Digital Forensics, Security and Law

Most organizations and government agencies regularly become engaged in litigation with suppliers, customers, clients, employees, competitors, shareholders, prosecutors or regulatory agencies that nearly assures the need to organize, retain, find and produce business records and correspondence, emails, accounting records or other data relevant to disputed issues. This article discusses some high visibility cases that constrain how metadata and content is routinely made available to opposing parties in civil litigation, to prosecutors in criminal prosecutions and to agency staff in regulatory enforcement litigation. Public policy, as implemented in the rules of evidence and pretrial discovery, restrict electronic data discovery (EDD) as …

Computer Forensics Field Triage Process Model, Marcus K. Rogers, James Goldman, Rick Mislan, Timothy Wedge, Steve Debrota

Journal of Digital Forensics, Security and Law

With the proliferation of digital based evidence, the need for the timely identification, analysis and interpretation of digital evidence is becoming more crucial. In many investigations critical information is required while at the scene or within a short period of time - measured in hours as opposed to days. The traditional cyber forensics approach of seizing a system(s)/media, transporting it to the lab, making a forensic image(s), and then searching the entire system for potential evidence, is no longer appropriate in some circumstances. In cases such as child abductions, pedophiles, missing or exploited persons, time is of the essence. In …

Alphaco: A Teaching Case On Information Technology Audit And Security, Hüseyin Tanriverdi, Joshua Bertsch, Jonathan Harrison, Po-Ling Hsiao, Ketan S. Mesuria, David Hendrawirawan

Journal of Digital Forensics, Security and Law

Recent regulations in the United States (U.S.) such as the Sarbanes-Oxley Act of 2002 require top management of a public firm to provide reasonable assurance that they institute internal controls that minimize risks over the firm’s operations and financial reporting. External auditors are required to attest to the management’s assertions over the effectiveness of those internal controls. As firms rely more on information technology (IT) in conducting business, they also become more vulnerable to IT related risks. IT is critical for initiating, recording, processing, summarizing and reporting accurate financial and non-financial data. Thus, understanding IT related risks and instituting internal …

Is Forensic Computing A Profession? Revisiting An Old Debate In A New Field, Bernd C. Stahl

Designing A Data Warehouse For Cyber Crimes, Il-Yeol Song, John D. Maguire, Ki Jung Lee, Namyoun Choi, Xiaohua Hu, Peter Chen

Journal of Digital Forensics, Security and Law

One of the greatest challenges facing modern society is the rising tide of cyber crimes. These crimes, since they rarely fit the model of conventional crimes, are difficult to investigate, hard to analyze, and difficult to prosecute. Collecting data in a unified framework is a mandatory step that will assist the investigator in sorting through the mountains of data. In this paper, we explore designing a dimensional model for a data warehouse that can be used in analyzing cyber crime data. We also present some interesting queries and the types of cyber crime analyses that can be performed based on …

An Agent-Based Model Of Trade With Distance-Based Transaction Cost, Kumar Venkat, Wayne W. Wakeland

Systems Science Faculty Publications and Presentations

This paper describes an application of agent-based modeling to investigate the effect of a distance-based transaction cost on trade. Long-distance trade is rapidly increasing, but may ultimately be constrained by our ability to move material goods between sellers and buyers. Unlike information exchange, trade in material goods is dependent on the price of oil and vulnerable to future scarcities of oil. In addition, there are growing concerns about greenhouse gas emissions from long-distance transportation. Our purpose in this study is to take the first step in understanding the impact of a distance constraint on free global trade using a simple …
