Steganography: Forensic, Security, And Legal Issues, Merrill Warkentin, Ernst Bekkering, Mark B. Schmidt

Journal of Digital Forensics, Security and Law

Steganography has long been regarded as a tool used for illicit and destructive purposes such as crime and warfare. Currently, digital tools are widely available to ordinary computer users also. Steganography software allows both illicit and legitimate users to hide messages so that they will not be detected in transit. This article provides a brief history of steganography, discusses the current status in the computer age, and relates this to forensic, security, and legal issues. The paper concludes with recommendations for digital forensics investigators, IT staff, individual users, and other stakeholders.

The "Scope Of A Student": How To Analyze Student Speech In The Age Of The Internet, Erin Reeves

Georgia Law Review

In three seminal cases dating from 1969-1988, the U.S. Supreme Court determined that students have a more limited right to free speech while within the confines of a public school building. In recent years, however, more and more cases have arisenin which it is not so clear whether a student speaker is "on-campus,"due in large part to the rapid increase in speech communicated over the Internet. This Note explores the possibility of how far the "confines of a public school building" should be extended in this age of the Internet. After analyzing the current confusion regarding what amount of restriction …

Opinionated Software, Meiring De Villiers

Vanderbilt Journal of Entertainment & Technology Law

Information security is an important and urgent priority in the computer systems of corporations, governments, and private users. Malevolent software, such as computer viruses and worms, constantly threatens the confidentiality, integrity, and availability of digital information. Virus detection software announces the presence of a virus in a program by issuing a virus alert. A virus alert presents two conflicting legal issues. A virus alert, as a statement on an issue of great public concern, merits protection under the First Amendment. The reputational interest of a plaintiff disparaged by a virus alert, on the other hand, merits protection under the law …

Fantasy Crime: The Role Of Criminal Law In Virtual Worlds, Susan W. Brenner

Vanderbilt Journal of Entertainment & Technology Law

This Article analyzes activity in virtual worlds that would constitute crime if they were committed in the real world. It reviews the evolution of virtual worlds like Second Life and notes research which indicates that more and more of our lives will move into this realm. The Article then analyzes the criminalization of virtual conduct that inflicts "harm" in the real world and virtual conduct that only inflicts "harm" in the virtual world. It explains that the first category qualifies as cybercrime and can be prosecuted under existing law. Finally, it analyzes the necessity and propriety of criminalizing the second …

On behalf of the Richmond Journal of Law and Technology, it is my pleasure to welcome you to our third issue for the 2007-2008 year, our Annual Survey of Electronic Discovery. This year’s Survey concentrates on the recent Amendments to the Federal Rules of Civil Procedure and its various implications on Electronic Discovery.

Remote Forensics May Bring The Next Sea Change In E-Discovery: Are All Networked Computers Now Readily Accessible Under The Revised Federal Rules Of Civil Procedure?, Joseph J. Schwerha, Scott Inch

Journal of Digital Forensics, Security and Law

The recent amendments to Rule 26 of the Federal Rules of Civil Procedure created a two-tiered approach to discovery of electronically stored information (“ESI”). Responding parties must produce ESI that is relevant, not subject to privilege, and reasonably accessible. However, because some methods of storing ESI, such as on magnetic backup tapes and within enormous databases, require substantial cost to access and search their contents, the rules permit parties to designate those repositories as “not reasonably accessible” because of undue burden or cost. But even despite the difficulty in searching for ESI, the party’s duty to preserve potentially responsive evidence …

On Communication, John Greenman

Michigan Law Review

Everybody knows that communication is important, but nobody knows how to define it. The best scholars refer to it. Free-speech law protects it. But no one-no scholar or judge-has successfully captured it. Few have even tried. This is the first article to define communication under the law. In it, I explain why some activities-music, abstract painting, and parading-are considered communicative under the First Amendment, while others-sex, drugs, and subliminal advertising-are not. I argue that the existing theories of communication, which hold that communicative behaviors are expressive or convey ideas, fail to explain what is going on in free-speech cases. Instead, …

Developing A Process Model For The Forensic Extraction Of Information From Desktop Search, Timothy Pavlic, Jill Slay, Benjamin Turnbull

Journal of Digital Forensics, Security and Law

Desktop search applications can contain cached copies of files that were deleted from the file system. Forensic investigators see this as a potential source of evidence, as documents deleted by suspects may still exist in the cache. Whilst there have been attempts at recovering data collected by desktop search applications, there is no methodology governing the process, nor discussion on the most appropriate means to do so. This article seeks to address this issue by developing a process model that can be applied when developing an information extraction application for desktop search applications, discussing preferred methods and the limitations of …

An Evaluation Of Windows-Based Computer Forensics Application Software Running On A Macintosh, Gregory H. Carlton

Journal of Digital Forensics, Security and Law

The two most common computer forensics applications perform exclusively on Microsoft Windows Operating Systems, yet contemporary computer forensics examinations frequently encounter one or more of the three most common operating system environments, namely Windows, OS-X, or some form of UNIX or Linux. Additionally, government and private computer forensics laboratories frequently encounter budget constraints that limit their access to computer hardware. Currently, Macintosh computer systems are marketed with the ability to accommodate these three common operating system environments, including Windows XP in native and virtual environments. We performed a series of experiments to measure the functionality and performance of the two …

Data Mining Techniques In Fraud Detection, Rekha Bhowmik

Journal of Digital Forensics, Security and Law

The paper presents application of data mining techniques to fraud analysis. We present some classification and prediction data mining techniques which we consider important to handle fraud detection. There exist a number of data mining algorithms and we present statistics-based algorithm, decision treebased algorithm and rule-based algorithm. We present Bayesian classification model to detect fraud in automobile insurance. Naïve Bayesian visualization is selected to analyze and interpret the classifier predictions. We illustrate how ROC curves can be deployed for model assessment in order to provide a more intuitive analysis of the models.

The 2007 Analysis Of Information Remaining On Disks Offered For Sale On The Second Hand Market, Andy Jones, Craig Valli, Glenn S. Dardick, Iain Sutherland

Journal of Digital Forensics, Security and Law

All organisations, whether in the public or private sector, increasingly use computers and other devices that contain computer hard disks for the storage and processing of information relating to their business, their employees or their customers. Individual home users also increasingly use computers and other devices containing computer hard disks for the storage and processing of information relating to their private, personal affairs. It continues to be clear that the majority of organisations and individual home users still remain ignorant or misinformed of the volume and type of information that is stored on the hard disks that these devices contain …

To License Or Not To License: An Examination Of State Statutes Regarding Private Investigators And Digital Examiners, Thomas Lonardo, Doug White, Alan Rea

Journal of Digital Forensics, Security and Law

In this paper the authors examine statutes that regulate, license, and enforce investigative functions in each US state. After identification and review of Private Investigator licensing requirements, the authors find that very few state statutes explicitly differentiate between Private Investigators and Digital Examiners. After contacting all state agencies the authors present a distinct grouping organizing state approaches to professional Digital Examiner licensing. The authors conclude that states must differentiate between Private Investigator and Digital Examiner licensing requirements and oversight.

The Forensics Aspects Of Event Data Recorders, Jeremy S. Daily, Nathan Singleton, Elizabeth Downing, Gavin W. Manes

Journal of Digital Forensics, Security and Law

The proper generation and preservation of digital data from Event Data Recorders (EDRs) can provide invaluable evidence to automobile crash reconstruction investigations. However, data collected from the EDR can be difficult to use and authenticate, complicating the presentation of such information as evidence in legal proceedings. Indeed, current techniques for removing and preserving such data do not meet the court’s standards for electronic evidence. Experimentation with an EDR unit from a 2001 GMC Sierra pickup truck highlighted particular issues with repeatability of results. Fortunately, advances in the digital forensics field and memory technology can be applied to EDR analysis in …

Data Security Measures In The It Service Industry: A Balance Between Knowledge & Action, N. Mlitwa, Y. Kachala

Journal of Digital Forensics, Security and Law

That “knowledge is power” is fast becoming a cliché within the intelligentsia. Such power however, depends largely on how knowledge itself is exchanged and used, which says a lot about the tools of its transmission, exchange, and storage. Information and communication technology (ICT) plays a significant role in this respect. As a networked tool, it enables efficient exchanges of video, audio and text data beyond geographical and time constraints. Since this data is exchanged over the worldwide web (www), it can be accessible by anyone in the world using the internet. The risk of unauthorised access, interception, modification, or even …

Book Review: Mac Os X, Ipod, And Iphone Forensic Analysis Dvd Toolkit, Gary C. Kessler

Journal of Digital Forensics, Security and Law

Apple's hold on the personal computer marketplace started dwindling on August 12, 1981, the day that the IBM PC was introduced. As an Apple ][+ bigot myself, I refused to touch a PC for some years. But I was also a command line bigot, so when the first Macintosh was introduced in 1983 and hermetically sealed the operating system from users, I did not go out and buy one. In fact, like many of my era, I did eventually end up on the PC side which, ironically, let me do many of the things that my trusty Apple ][+ had …

The Dangers Of The Digital Millennium Copyright Act: Much Ado About Nothing?, Steve P. Calandrillo, Ewa A. Davison

Articles

In 1998, Congress passed the Digital Millennium Copyright Act (DMCA), a landmark piece of legislation aimed at protecting copyright holders from those who might manufacture or traffic technology capable of allowing users to evade piracy protections on the underlying work. At its core, the DMCA flatly prohibits the circumvention of “technological protection measures” in order to gain access to copyrighted works, but provides no safety valve for any traditionally protected uses.

While hailed as a victory by the software and entertainment industries, the academic and scientific communities ties have been far less enthusiastic. The DMCA’s goal of combating piracy is …

Bringing An End To Warrantless Cell Phone Searches, Bryan A. Stillwagon

Georgia Law Review

Cell phones keep society connected, and exploring their contents reveals a glimpse into the user's life. As technology develops and these phones advance, this glimpse becomes a more complete picture of the user's life. The Fourth Amendment speaks of a right to be secure against unreasonable searches and seizures, but this right is threatened when judges permit the few exceptions to the warrant requirement to envelop the general rule. This Note begins with a brief review of the history of both cellphones and warrantless searches, followed by the recent history of warrantless cell phone searches. While focusing on the search- …
