On Efficiency Of Distributed Password Recovery, Radek Hranický, Martin Holkovič, Petr Matoušek

Journal of Digital Forensics, Security and Law

One of the major challenges in digital forensics today is data encryption. Due to the leaked information about unlawful sniffing, many users decided to protect their data by encryption. In case of criminal activities, forensic experts are challenged how to decipher suspect's data that are subject to investigation. A common method how to overcome password-based protection is a brute force password recovery using GPU-accelerated hardware. This approach seems to be expensive. This paper presents an alternative approach using task distribution based on BOINC platform. The cost, time and energy efficiency of this approach is discussed and compared to the GPU-based …

Towards Syntactic Approximate Matching - A Pre-Processing Experiment, Doowon Jeong, Frank Breitinger, Hari Kang, Sangjin Lee

Journal of Digital Forensics, Security and Law

Over the past few years the popularity of approximate matching algorithms (a.k.a. fuzzy hashing) has increased. Especially within the area of bytewise approximate matching, several algorithms were published, tested and improved. It has been shown that these algorithms are powerful, however they are sometimes too precise for real world investigations. That is, even very small commonalities (e.g., in the header of a le) can cause a match. While this is a desired property, it may also lead to unwanted results. In this paper we show that by using simple pre-processing, we signicantly can in uence the outcome. Although our test …

Log Analysis Using Temporal Logic And Reconstruction Approach: Web Server Case, Murat Gunestas, Zeki Bilgin

Journal of Digital Forensics, Security and Law

We present a post-mortem log analysis method based on Temporal Logic (TL), Event Processing Language (EPL), and reconstruction approach. After showing that the proposed method could be adapted to any misuse event or attack, we specifically investigate the case of web server misuses. To this end, we examine 5 different misuses on Wordpress web servers, and generate corresponding log files of these attacks for forensic analysis. Then we establish attack patterns and formalize them by means of a special case of temporal logic, i.e. many sorted first order metric temporal logic (MSFOMTL). Later on, we implement these attack patterns in …

An Automated Approach For Digital Forensic Analysis Of Heterogeneous Big Data, Hussam Mohammed, Nathan Clarke, Fudong Li

Journal of Digital Forensics, Security and Law

The major challenges with big data examination and analysis are volume, complex interdependence across content, and heterogeneity. The examination and analysis phases are considered essential to a digital forensics process. However, traditional techniques for the forensic investigation use one or more forensic tools to examine and analyse each resource. In addition, when multiple resources are included in one case, there is an inability to cross-correlate findings which often leads to inefficiencies in processing and identifying evidence. Furthermore, most current forensics tools cannot cope with large volumes of data. This paper develops a novel framework for digital forensic analysis of heterogeneous …

Countering Noise-Based Splicing Detection Using Noise Density Transfer, Thibault Julliand, Vincent Nozick, Hugues Talbot

Journal of Digital Forensics, Security and Law

Image splicing is a common and widespread type of manipulation, which is defined as pasting a portion of an image onto a second image. Several forensic methods have been developed to detect splicing, using various image properties. Some of these methods exploit the noise statistics of the image to try and find discrepancies. In this paper, we propose a new counter-forensic approach to eliminate the noise differences that can appear in a spliced image. This approach can also be used when creating computer graphics images, in order to endow them with a realistic noise. This is performed by changing the …

Verification Of Recovered Digital Evidence On The Amazon Kindle, Marcus Thompson, Raymond Hansen

Journal of Digital Forensics, Security and Law

The Amazon Kindle is a popular e-book reader. This popularity will lead criminals to use the Kindle as an accessory to their crime. Very few Kindle publications in the digital forensics domain exist at the time of this writing. Various blogs on the Internet currently provide some of the foundation for Kindle forensics. For this research each fifth generation Kindle was populated with various types of files a typical user may introduce using one method, the USB interface. The Kindle was forensically imaged with AccessData’s Forensic Toolkit Imager before and after each Kindle was populated. Each file was deleted through …

Bytewise Approximate Matching: The Good, The Bad, And The Unknown, Vikram S. Harichandran, Frank Breitinger, Ibrahim Baggili

Journal of Digital Forensics, Security and Law

Hash functions are established and well-known in digital forensics, where they are commonly used for proving integrity and file identification (i.e., hash all files on a seized device and compare the fingerprints against a reference database). However, with respect to the latter operation, an active adversary can easily overcome this approach because traditional hashes are designed to be sensitive to altering an input; output will significantly change if a single bit is flipped. Therefore, researchers developed approximate matching, which is a rather new, less prominent area but was conceived as a more robust counterpart to traditional hashing. Since the conception …

Security Analysis Of Mvhash-B Similarity Hashing, Donghoon Chang, Somitra Sanadhya, Monika Singh

Journal of Digital Forensics, Security and Law

In the era of big data, the volume of digital data is increasing rapidly, causing new challenges for investigators to examine the same in a reasonable amount of time. A major requirement of modern forensic investigation is the ability to perform automatic filtering of correlated data, and thereby reducing and focusing the manual effort of the investigator. Approximate matching is a technique to find “closeness” between two digital artifacts. mvHash-B is a well-known approximate matching scheme used for finding similarity between two digital objects and produces a ‘score of similarity’ on a scale of 0 to 100. However, no security …

The Sea Is Rising… But Not Onto The Policy Agenda: A Multiple Streams Approach To Understanding Sea Level Rise Policies, Juita-Elena (Wie) Yusuf, Katharine Neill, Burton St. John Iii, Ivan K. Ash, Kaitrin Mahar

School of Public Service Faculty Publications

There has been little policy effort to address sea level rise in coastal states in the US. It is important to examine, at the state level, how the multitude of different (and changing) actors with different preferences and perspectives contribute to such inertia. This study examines state-level legislative inaction with regards to sea level rise. Using Kingdon's multiple streams framework, we draw a picture of the policy landscape in Virginia as one where the problem of sea level rise is perceived as a low priority, with little consensus on achievable policy solutions, and is politically controversial. We find that policy …

Erforschung biologischer Ressourcen der Mongolei / Exploration into the Biological Resources of Mongolia, ISSN 0440-1298

Parasite diversity in and among various species of mammals within Mongolia is still poorly understood. The current paper focusses on a small part of the results of the Mongolian Vertebrate Parasite Project (MVPP), which entailed a broad-scale biodiversity survey of the vertebrates and their parasites of the Gobi and Altai regions of Mongolia. We report on the prevalence and morphological variation of larval cestodes of the family Taeniidae that occurred in small mammals that were collected from 2009-2012 from various locations in southern Mongolia. From these metacestodes, we studied both large and small rostellar hooks and analyzed both size and …

Audience Segmentation For Campaign Design: Addressing Climate Change In Singapore, Benjamin H. Detenber, Sonny Rosenthal, Youqing Liao, Shirley S. Ho

Research Collection College of Integrative Studies

A nationally representative telephone survey (n = 1,006) was conducted to understand how different groups of Singaporeans regard the issue of climate change and their inclination toward action in dealing with it. We measured attitudes, knowledge, and perceptions of the problem of climate change and the role of various stakeholders in addressing it. The data were subjected to a latent class analysis to produce three distinctive segments of the population: the concerned, the disengaged, and the passive. These segments stand in contrast to those discovered in the United States, Australia, Germany, and India and suggest different strategies for public engagement …

Hazardready – A Geographically Based Natural Hazard Education And Preparedness Web Application, Carson C. Macpherson-Krutsky Ms.

Graduate Student Theses, Dissertations, & Professional Papers

Earthquakes, floods, wildfires, and other natural disasters are inevitable and costly both in terms of lives lost and money spent on recovery. Scientific research on natural hazards is widely shared within the scientific community, but is less often made more widely accessible, as methods or pathways for providing scientific natural hazard information and data in non-technical language are limited. Priorities for imparting hazard information include: 1) scientific accuracy, 2) spatial granularity, 3) integration of information about all relevant hazards, 4) nontechnical content, 5) appropriate preparedness activities, and 6) engagement with existing disaster response and mitigation capabilities. In response to these …

Mind The Gap: The Importance Of Pluralistic Discourse In Computing For Mental Health, R. Jordan Crouser, Morganne Ray Crouser

Computer Science: Faculty Publications

A large amount of HCI research leverages studies from psychology to try to understand how humans work. Unfortunately, there is often a disconnect between the tightly- controlled laboratory studies being referenced and the application of this knowledge in practice. At the same time, many mental health practitioners are beginning to turn toward computational tools to help stretch limited resources and support equitable access to mental healthcare. These efforts could be dramatically enhanced by leveraging what the HCI community has learned about promoting active engagement and designing unobtrusive interfaces. By facilitating collaboration between HCI researchers and practitioners in the field of …

Adoption Of Electronic Health Record Systems Within Primary Care Practices, Marvin Leon Reid, Jr.

Walden Dissertations and Doctoral Studies

Primary care physicians (PCPPs) have been slow to implement electronic health records (EHRs), even though there is a U.S. federal requirement to implement EHRs. The purpose of this phenomenological study was to determine why PCPPs have been slow to adopt electronic health record (EHR) systems despite the potential to increase efficiency and quality of health care. The complex adaptive systems theory (CAS) served as the conceptual framework for this study. Twenty-six PCPPs were interviewed from primary care practices (PCPs) based in southwestern Ohio. The data were collected through a semistructured interview format and analyzed using a modified van Kaam method. …

Electronic Warrant Systems: The Effect Of Advanced Technologies On Arrest Performance, Gerald Lee Ward

Walden Dissertations and Doctoral Studies

Public safety is negatively affected when arrest warrant information is not available to law enforcement officers, judges, prosecutors, and other criminal justice practitioners. The U.S. Government and the criminal justice community have advocated for electronic warrant systems (e-warrants). Peace officers know that when e-warrant systems deliver warrant information to them immediately from multiple jurisdictions, their safety is increased. However, the factors that cause these e-warrants systems to improve safety are not known. The purpose of this historical data analysis study was to determine if the use of e-warrant systems resulted in shorter clearance times than the use of legacy paper-based …

A Qualitative Examination Of The Perception Of Risk In Warnings For Severe Weather, Teresa Simmons

Walden Dissertations and Doctoral Studies

In the past decade, weather disasters have claimed thousands of lives and resulted in billions of dollars in damages. Awareness of a storm threats can occur hours or days in advance, but disaster assessments indicate many people do not heed storm warnings. This problem is old. Despite 50 years of research, and new technologies and training to improve responsiveness, the basic issue– understanding how people interpret and respond to weather warnings–persists. An exploratory study that incorporated human behavior theories and communication models not traditionally associated with severe weather analysis was conducted to learn how weather risks are perceived by nonscientists. …
