Adaptive Interpolation Algorithms For Temporal-Oriented Datasets, Jun Gao

School of Computing: Dissertations, Theses, and Student Research

Spatiotemporal datasets can be classified into two categories: temporal-oriented and spatial-oriented datasets depending on whether missing spatiotemporal values are closer to the values of its temporal or spatial neighbors. We present an adaptive spatiotemporal interpolation model that can estimate the missing values in both categories of spatiotemporal datasets. The key parameters of the adaptive spatiotemporal interpolation model can be adjusted based on experience.

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

Annual ADFSL Conference on Digital Forensics, Security and Law

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 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 …

The early results have created a preliminary CBK, and final validation is underway.

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.

A Multilane Pipelined Architecture For Real Time Enhancement Of Color Video Streams, Adam Redd Livingston

Electrical & Computer Engineering Theses & Dissertations

Video stream enhancement is a key fixture in a wide variety of applications from video surveillance, automatic navigation, medical imagery, to facial/object recognition systems. When a video stream contains non-uniform lighting it can be difficult to obtain what is in the darker regions without over enhancing brighter regions. The Adaptive and Integrated Neighborhood Dependant Approach for Nonlinear Enhancement (AINDANE) algorithm combines a tunable nonlinear transfer function, convolution by a multi-scale Gaussian kernel, and tunable contrast enhancement to address this problem for a single image. Luminance values are tuned based on the global cumulative distribution function (CDF) of an image. Contrast …

Mobius: An Omnidirectional Robotic Platform And Software Architecture For Network Teleoperation, Samuel Aaron Miller

Electrical & Computer Engineering Theses & Dissertations

The following thesis presents the results of a project to develop and test an omnidirectional robotic system (hardware and software) at NASA Langley Research Center's Robotics and Intelligent Machines Lab. The impetus for the project was the unique capabilities of omnidirectional systems. Some of the many potential benefits these systems have include improved material-handling capabilities in constrained environments (such as might be found in extraterrestrial manned habitats), efficient camera-based vehicle teleoperation, and simplified route planning for autonomous robot operations.

The project's focus was to design, build, and test a system that used Mecanum wheels to achieve omnidirectional motion. In addition …

Information Visualization Methods And Techniques Using Web Services, Kevin Dupigny

Computational Modeling & Simulation Engineering Theses & Dissertations

Data, even in small amounts, can be difficult to interpret quickly and efficiently. Data domains are continually expanding and making this data available and usable in collaborative data environment is a challenge that was not addressed by legacy systems. Such a framework would make the existence of a global information sharing system feasible. Visualizing this complex dataset presents a complex task for current static interface solutions. A flexible layered service oriented model is presented in this work to approach this challenge. The visual scope of human perception is largely untapped by today's data visualization applications. Human mental processes are adept …

A Component Based Formal Ontology Model, A Method For Evaluating Such A Model, And The Results Of An Application Of That Method, Charles Tumitsa

Computational Modeling & Simulation Engineering Theses & Dissertations

For systems to truly communicate effectively, more than just data interchange is necessary. The systems must achieve conceptual interoperability, which implies communicating with understanding.

The LCIM (Levels of Conceptual Interoperability Model) describes a number of levels of interoperability, each of which shows systems with an increased amount of conceptual understanding of the other systems they are communicating with. The lowest levels of this model, technical and syntactic interoperability, are achieved (and there are many existing examples) via data exchange in a number of different ways. Research has shown, however, that to attain higher levels of conceptual understanding, that there must …
