��Vlog��ýLR student researches how to keep cars safe from hacking

Ajani Oyindamola — Fri, 12 Aug 2016 18:04:06 +0000

In 2015, two researchers a Jeep Cherokee being driven by a reporter who documented how the researchers controlled everything from the car’s radio and media console to its brakes and steering. For Dr. Shucheng Yu, an associate professor of computer science at the University of Arkansas at Little Rock, the exercise demonstrated how vulnerable smart cars with GPS, Bluetooth, and internet connections are to cyberattacks. “These cars have become the trend of the future,” Yu said. “There could be some very severe consequences if someone hacked into the car. A car can be fully controlled by the hacker if it is not protected.” So Yu and his student, Zachary King, a junior majoring in computer science at ��Vlog��ýLR, spent the summer researching how to keep cars safe from cyberattacks. They worked on the project during an intensive eight-week summer research program at ��Vlog��ýLR. King was one of 10 college students from across the country recruited through a National Science Foundation grant-funded project, “REU Site: CyberSAFE@��Vlog��ýLR: Cyber Security and Forensics Research at the University of Arkansas at Little Rock.” The goal of the program is to decrease cyberattacks on people using mobile technology and social networking sites, said Dr. Mengjun Xie, an associate professor of computer science and director of the CyberSAFE@��Vlog��ýLR program. “The basic idea is to integrate cybersecurity and cyber forensics research with the latest technology in mobile cloud computing and social media to provide research opportunities to students,” Xie said. More than 130 students applied for 10 spots. Participants included undergraduate college students with a grade point average of 3.0 or higher who are majoring in computer science, computer engineering, math, physics, or electrical engineering. Those selected spent eight weeks conducting research full time with a faculty mentor at the University of Arkansas at Little Rock. Participants received a $4,000 stipend, on-campus housing, a meal plan, and travel expenses.

How to protect your smart car

In his project, “Investigating and Securing Communications in the Controller Area Network (CAN), King created a security protocol to protect smart cars from hacking. He also built an experimental environment that simulates the communication system in a smart car, which allows the security protocol to be tested through simulations. The research focuses on the development of a security protocol to protect the Controller Area Network (CAN), an internal communications system in vehicles. “There are many ways that hackers can control CAN,” King said. “Once they access it, hackers can pretty easily control your car however they want. We are proposing to add a layer of security, so if an unauthorized person accesses it, they still wouldn’t be able to control your vehicle.” The security protocol protects the CAN in two ways. It authenticates messages sent through the network by creating an authentication code. This authentication code allows nodes on the network to differentiate between a valid message and an attacker’s message. The second security feature protects against replay attacks, when a hacker attempts to breach the network by repeatedly sending an old message. The protocol uses a timestamp to calculate when the network last received the message, which verifies the message’s “freshness.” Yu and King are continuing their research this fall. In the future, Yu hopes to collaborate with industry and funding agencies to implement the security protocol in commercial vehicles and protect cars from hackers. As for King, participating in this summer research program has left him considering a career in cybersecurity once he graduates in 2018. “Three months ago, I wouldn’t have been able to tell you much about cybersecurity and what a security protocol would look like,” he said. “After having completed this program, I am more interested in cybersecurity than I was before, and I may end up going that route.”

A summer of innovative research

The CyberSAFE@��Vlog��ýLR participants were honored during a commencement ceremony July 29 at the ��Vlog��ýLR Engineering and Information Technology Building. Their research topics range from utilizing cybersecurity and social network forensics to understanding cyber warfare to the use of facial emotion recognition for security purposes.

��Vlog��ýLR professor monitors anti-NATO narratives for Operation Brilliant Jump

Ajani Oyindamola — Tue, 14 Jun 2016 14:44:07 +0000

A University of Arkansas at Little Rock professor and his team of student researchers are investigating how groups are using social media to respond to NATO exercises. Dr. Nitin Agarwal, the ��Vlog��ýLR Jerry L. Maulden-Entergy endowed chair and a professor of information science, monitored social media responses to, a 2,500-person NATO exercise that focused on the logistics of moving troops and heavy equipment from Spain to Poland within four days. “During the exercise, our role was to examine the social media information environment and identify what type of narratives are being disseminated,” Agarwal said. “More specifically, how are anti-NATO groups reacting to the exercise and the media coverage that NATO public affairs is putting out?” Brilliant Jump, which ran May 17-27, was the third in a series of four NATO exercises taking place in Poland. The aim of the exercise was to train the Very High Readiness Joint Task Force to deploy quickly to an assigned area of operations following the activation of the NATO Response Force. Agarwal’s student research team members include Shiblee Nooman and Abu Fahad Siddiqui, who are earning master’s degrees in information quality, as well as Samer Al-khateeb and Muhammad Nihal Hussain, who are earning doctorates in information science. A fifth team member, Mainuddin Shaik, recently graduated with a master’s degree in information quality and will be working at HP in El Paso, Texas. Agarwal’s team worked in collaboration with other university teams, including Carnegie Mellon and Arizona State, to monitor the social media responses of information disseminated by the NATO public affairs office and by news organizations. The ��Vlog��ýLR team analyzed blogs via, a blog analysis tool Agarwal created. Specifically, Agarwal and his team searched for cyber propaganda campaigns conducted by anti-NATO groups. Cyber propaganda campaigns are deceptive online movements that manifest in physical behaviors and events. These groups ��use social media to recruit followers, spread propaganda, and encourage action. During Brilliant Jump, anti-NATO bloggers used NATO-disseminated images, videos, and information to spread a narrative that NATO was using the training exercise to prepare for war against Russia. “The idea is to influence the thinking of people into misleading them into thinking that there is an act of aggression against Russia,” Agarwal said. “Misinformation is rampant. It’s everywhere on social media. As information scientists, we should be able to provide ways to measure how truthful or how correct this information is and be able to guide the reader and make them aware of these challenges.” To help combat the growing threat of cyber campaigns, Agarwal and his graduate students are using social network analysis, cyber forensics, and deep web searches to study cyber campaigns to develop models for detecting and predicting the online behaviors of deviant groups. “I have found a lot of conventional propaganda techniques being used in modern spaces like Twitter and Instagram,” Hussain said. “This is a type of social engineering being used to coerce people into believing certain things. I am trying to understand and develop models to identify strategies of propaganda in social media and to help people develop counternarratives and countermeasures to defeat a certain narrative or to eliminate propaganda narratives.” Their research will determine the universal characteristics of cyber campaigns, develop models to identify propaganda strategies used in social media, and help develop countermeasures that can be used to defeat propaganda narratives, Hussain said. “The next phase of battle will be in cyberspace,” Al-khateeb said. “I think the next type of war will be more of a cyber war than a physical war, where you can influence people’s thinking in an easier way using social media.” In addition to Brilliant Jump, Agarwal and his team are also monitoring the social media output regarding. Taking place from June 7-17, this operation is a Polish national exercise that seeks to train, exercise, and integrate Polish national command and force structures into an allied, joint, multinational environment. �� The work is funded in part by a $186,692 grant from the U.S. Office of Naval Research, titled “Analyzing Integrated Social Media-Facilitated Propaganda Campaigns Using Social Network Analysis and Cyber Forensics,” and a $300,000 grant from the U.S. Army Research Office, titled “Towards Predictive Modeling Deviant Cyber Flash Mobs: A Socio-Informatics Driven Hypergraph Framework.” The grant builds on Agarwal’s already significant body of social media research and behavioral modeling. It is part of a larger research program in his Center Of Social Media and Online behavioral Studies (COSMOS) lab. More details on these projects can be found on Agarwal’s project website.

Grant helps fund research into violent flash mobs

��Vlog��ý Little Rock — Wed, 04 May 2016 19:34:31 +0000

Thanks to a new grant, a University of Arkansas at Little Rock researcher is expanding his investigation of cyber flash mobs — particularly those that lead to violent or damaging behavior. A U.S. Army Research Office grant will provide nearly $300,000 during the next three years to further the research of Dr. Nitin Agarwal, Jerry L. Maulden-Entergy endowed chair and ��Vlog��ýLR professor of information science. The award — Agarwal’s third in the past six months — is funded by the under the Social and Cognitive Networks program within the Network Sciences division. It provides Agarwal with $82,338 for the first year of his project, “Towards Predictive Modeling Deviant Cyber Flash Mobs: A Socio-Informatics Driven Hypergraph Framework.” �� Agarwal’s project will analyze the formation of cyber flash mobs, investigating how and why the gatherings occur and why they’re so effective. A relatively new phenomenon rooted in Internet communities such as Facebook, Twitter, and blogs, cyber flash mobs are defined by Agarwal as “self-organized groups of individuals who get together at a public place or even Internet (cyber) spaces, perform an unpredicted act, and quickly disperse into anonymity.” Though the activities of these groups can range from dance performances to peaceful protests, numerous groups promote violent, extremist, or otherwise negatively disruptive behavior. The project will focus on the science behind the mob-building tactics of these online groups that may have a physical manifestation. The central goal of the research is to develop an accurate, practical model for predicting how and if an extremist group will launch a cyber flash mob. To accomplish this, Agarwal and graduate student assistants working with him will gather data on past violent cyber flash mobs. They will then analyze the information, pinpointing the common elements in the groups’ strategies. Agarwal suggests that rhetoric and network ties are critical for flash mob mobilization. By creating a unified identity through their online messages, these groups can heavily influence the thinking and steer the behavior of their audience. This new project builds on Agarwal’s already significant body of social media research and behavioral modeling. It is part of a larger research program in his social computing lab, including efforts that are funded by the U.S. National Science Foundation, U.S. Office of Naval Research, U.S. Air Force Research Lab, and U.S. Army Research Office. More details on these projects can be found on Agarwal’s project website.

Researcher receives grant to further study ‘deviant’ social media behaviors

Shanna Fitzgerald — Thu, 10 Dec 2015 16:02:42 +0000

A new grant from the Department of the Navy, Office of Naval Research (ONR) will help a University of Arkansas at Little Rock professor further establish himself as a leader in social media research. The grant, which builds on a previous ONR-funded project that Dr. Nitin Agarwal conducted, enables him and his team to dig deeper into the organized use of social media by deviant groups to spread misinformation, stoke violence and panic, and conduct recruitment and radicalization campaigns. Agarwal is the Jerry L. Maulden-Entergy Endowed Chair and a professor of information science at ��Vlog��ýLR. �� His previous project, “Predictive Modeling of Cyber Flash Mobs: Understanding Emerging Socio-Technical Behavior for Conflict Monitoring,” investigated how groups mobilize and spark action in the “real” world via social media. The recent $85,964 grant will fund new computational equipment that will allow the researchers to conduct richer, more nuanced examinations of social media tactics and patterns, leading to practical, innovative results. It will also allow the ��Vlog��ýLR researchers to work directly with researchers at Arizona State University, University of Maryland Center for Advanced Studies of Language, Naval Postgraduate School, and Carnegie Mellon University, easily sharing discoveries, resources, and knowledge. “The equipment will enable further discovery and analysis (and) data and knowledge exchange among stakeholders,” Agarwal said. Though the field and use of social media propaganda is relatively young, the relevance and importance of this research is significant, Agarwal said. “There is a need to systematically study these new artificial means of spreading rumors, hate speech, viewpoints, and opinions,” he said. The recently funded project is part of a larger research program in Agarwal’s lab, funded by the National Science Foundation, Office of Naval Research, Air Force Research Lab, and Army Research Office. This project is sponsored by the Department of the Navy, Office of Naval Research under the Defense University Research Instrumentation Program (DURIP).

NIH grant kickstarts ��Vlog��ýLR project to enhance cancer treatment

Shanna Fitzgerald — Tue, 30 Jun 2015 13:47:27 +0000

With the help of a nearly $400,000 federal grant, a University of Arkansas at Little Rock professor will soon launch a project that ultimately might improve cancer diagnosis and treatment. The National Institutes of Health awarded Dr. Mary Yang a $373,520 grant for her project investigating the relationship between genes and the development of cancer. During the course of her research project, Yang will develop computational approaches for observing and tracking genetic mutations. Yang is a ��Vlog��ýLR associate professor in the Department of Information Science and the director of bioinformatics, a joint program of ��Vlog��ýLR and the University of Arkansas for Medical Sciences. The three-year project is renewable for up to six years and will include annual research goals. Dr. Kenji Yoshigoe, a collaborator in the effort, is director of the ��Vlog��ýLR Computational Research Center, where the supercomputing portion of the research project will occur. In addition to its potential contributions to cancer and precision medicine research, the project will give students valuable experience in developing computer approaches to biomedical problems.

Dr. Mary Yang

With Yang serving as the principal investigator, both undergraduate and graduate students in the joint ��Vlog��ýLR-��Vlog��ýMS Bioinformatics program will participate in research work throughout the project. Dr. Elizabeth Pierce, chair of Information Science, will work closely with Yang in promoting synergistic research and education at ��Vlog��ýLR. The potential benefits of the project extend beyond research and student growth. “In the future we will collaborate with ��Vlog��ýMS to transfer our results to clinical practice,” Yang said. “We aim to extend our computational framework to other types of disorders.” The project begins July 1.

��Vlog��ýLR professor contributes collaborative model for European Union

Gloria King — Tue, 12 May 2015 13:38:41 +0000

A leading academic journal has published the research of ��Vlog��ýLR’s Dr. Rolf Wigand proposing a Common Information Model for electronic documents and mapping software in the European Union.

Dr. Rolf Wigand

Wigand and several colleagues from other universities say the goal is to improve taxation and customs systems across EU nations. Their article stems from a $7.5 million European Union-funded research project of more than four years called “Information Technology for Adoption and Intelligent Design for E-Government.” The model requires new public-private partnerships between government and private businesses that enhance security and controls. The model employs intelligent software tools to reduce administrative loads, according to Wigand. “One of the great challenges for European governments is solving the paradox of increasing the security of international trade, while simultaneously reducing overhead for commercial as well as public administrations,” Wigand said. Finding the right balance between control and cost of information gathering is the key to increase competitiveness of European businesses locally, nationally and internationally, he added. “To encourage the adoption of these redesigned procedures, a truly collaborative co-design process that creates win-win benefits for all stakeholders, is essential,” Wigand concluded. Wigand wrote “Understanding transnational information systems with supranational governance: A multi-level conflict management perspective” with co-authors Boriana Rukanova, Eveline van Stijn, and Yao-Hua Tan. The article is published in the journal “Government Information Quarterly,” from the publisher until June 15. Wigand is the Maulden-Entergy Chair and Distinguished Professor Emeritus for the��Departments of Information Science and Business Information Systems at ��Vlog��ýLR.

Doctoral student presents research at Harvard University

Gloria King — Tue, 16 Dec 2014 22:10:29 +0000

A doctoral student in information science at ��Vlog��ýLR presented research at Harvard University this week that indicates, among other things, privacy policies published by most businesses are not consumer-friendly. Therese L. Williams, lead author of “Protecting Private Information: Current Attitudes Concerning Privacy Policies,” was invited to present at the sixth annual Academy of Science and Engineering International Conference on Privacy, Security, Risk, and Trust at Harvard. Fewer than 10 percent of the new research submissions from academia, government, and industry are accepted for presentation at the annual event. Using data from an online survey conducted in spring 2014, Williams’ research delves into whether attitudes concerning privacy have changed over the last decade. She says that, as written, privacy policies published by the majority of businesses serve only to protect organizations from sharing or selling consumers’ private information to other organizations, but are not readable by the average consumer. Williams’ research suggests that “a new social contract about individuals’ private, and supposedly confidential, information should be developed to protect this information, while still allowing the spread of technology and online commerce.” For her research, survey respondents answered such questions as whether they had posted a photo on a social networking site and how often they read privacy policies posted on a business’ web page. Williams said she was rather surprised to find that, compared with research published by Annenberg Public Policy Center in 2005, attitudes regarding privacy have not changed much in the last 10 years. According to Williams, many consumers do not have a complete picture of the personal information that is aggregated and shared. Without federal laws to mandate the use of privacy policies or how they are written, multiple industries self regulate. Based on her research, Williams said it is clear that effective self-regulation for consumer privacy has yet to emerge. Williams is mentored by ��Vlog��ýLR Associate Professor of Information Science Nitin Agarwal and Distinguished Professor and Maulden-Entergy Chair Rolf T. Wigand, who also holds a joint appointment in the Department of Business Information Systems.

EIT’s Information Science faculty contribute to new book

��Vlog��ý Little Rock — Wed, 10 Sep 2014 18:15:11 +0000

Two Information Science Department faculty members in the University of Arkansas at Little Rock’s College of Engineering and Information Technology and a Carleton University scholar have co-edited a recently published book. Online Collective Action: Dynamics of the Crowd in Social Media stems from a National Science Foundation research grant directed by Drs. Nitin Agarwal and Rolf Wigand, along with Dr. Merlyna Lim, Canada research chair at Carleton University. Published Aug. 2 by Springer, the book is the fourth in a regular series of texts on social networks. The editors note in the book a recent surge in research devoted to online collective action, a relatively new and fast-moving phenomenon propelled by the use of rapidly developing technologies on the ground. The book argues that contemporary collective actions, from the 2011 Egyptian Tahrir uprising to the 2013 Turkish protest in Gezi Park, cannot be separated from the uses of social media. It addresses the gap in the current collective action literature exposed by the new information and communication technologies landscape by bringing together qualitative and quantitative studies from computational and social sciences. By carefully selecting a number of qualitative and quantitative studies from computational and social sciences focusing on online collective actions, the new book seeks to promote a symbiotic and synergistic advancement of the multiple, interconnected disciplines. The researchers’ work observing Saudi Arabian female activists who used social media platforms to protest against gender-biased laws and practices in that country helped them earn a Best Publication of 2012 Award at the International Conference on Information Systems in Milan, Italy, in December 2013. The award recognized the article as the best among the nominations from each of the 36 worldwide information system journals each year by the Senior Scholars Consortium of the Association for Information Systems. Agarwal is an associate professor and Wigand is the Maulden-Entergy Chair and Distinguished Professor in the ��Vlog��ýLR EIT Information Science Department.

Professor’s data mining research stands ‘Test of Time’

��Vlog��ý Little Rock — Thu, 21 Aug 2014 14:09:48 +0000

A ��Vlog��ýLR Department of Information Science professor has received a prestigious “Test of Time Award” in recognition of the groundbreaking research he conducted nearly 20 years ago. Dr. Xiaowei Xu’s research was originally published for Knowledge Discovery from Databases (KDD), a leading international forum for data science, data mining, knowledge discovery, large-scale data analytics, and big data. The KDD community recently formed a committee to consider nominees for the first “Test of Time Award” in recognition of research with lasting impact. The committee reviewed all KDD conference papers published between 1995 and 2004. Xu is being��honored at the sold-out 2014 KDD Conference in New York City��this week, Aug. 24-27,��in which a record-breaking 2,200��people��are in attendance,��and where he��is��joined by only two other recipients of the award. Xu’s paper, “A Density-Based Algorithm for Discovering Clusters in Large Spatial Databases with Noise,” proposed a new algorithm for strategically mining large amounts of data. It was first published in 1996, but the theories contained within it still have practical applications today. The paper introduced density-based clustering to the data mining community using the now well-known algorithm, DBSCAN. In the years since it was first brought to public attention, the algorithm has been featured in numerous textbooks and cited by thousands of researchers. “This award speaks to Dr. Xu’s incredible analytic talent,” said Liz Pierce, ��Vlog��ýLR information science chairperson. “It adds to the prestige of our program, and it is an inspiration for our students to have someone of his caliber as a research mentor.” Xu received a��doctorate in computer science from the University of Munich in Germany and a��master’s degree from the Shenyang Institute of Computing Technology of the Chinese Academy of Sciences in Shenyang, China. He received a bachelor of science in mathematics from Nankai University in Tianjin, China. Visit the ��Vlog��ýLR Department of Information Science for more information.

Military funds professor’s social media research on Ukraine

��Vlog��ý Little Rock — Tue, 05 Aug 2014 16:28:39 +0000

An associate professor at ��Vlog��ýLR has received military grant funding that could provide insight into the continued crisis in Ukraine. The research findings are already being used by NATO. Project funding from the U.S. Office of Naval Research (ONR) is supporting the social media research of Dr. Nitin Agarwal of the ��Vlog��ýLR Information Science Department. Working closely with the NATO officers, Agarwal will compute and analyze the sea of available data related to the Ukrainian crisis in the form of tweets, blog posts, and other social media, using tracking monitoring tools and previously published social media research methodologies published by his team. He used similar tools to track and then later create a three-dimensional representation (above) of the social media campaign organized by Saudi Arabian women last fall to protest against the driving ban. Recently, as Agarwal gazed into a computer monitor filled with a dizzying array of brightly colored dots representing persons and “bots” on social media, he said the rise of such platforms has enabled global connections, both positive and negative, like never before.

Dr. Nitin Agarwal

Analyzing these interactions could reveal such things as the emergence or decline of political leadership or help de-escalate a growing crisis in a global hotspot. “Basically, this is an effort to boil down reams of data into relevant information,” said Agarwal. “That information could help policy makers in the decision-making process, and it could also help counteract disinformation and propaganda campaigns circulating out there.” The project’s title is “Predictive Modeling of Cyber Flash Mobs: Understanding Emerging Socio-Technical Behaviors for Conflict Monitoring.” The ONR-funded project yielded $160,000 through Sept. 30, 2015. In addition, research arms in two other branches of the U.S. military have provided grant funding for Agarwal’s projects. One of those, funded by the U.S. Army Research Office’s Modeling of Complex Systems program for $15,000, will run through November 2016. Another project for the U.S. Air Force Research Lab, titled “Social Media Categorization Study,” is funded for $150,000 and runs through Feb. 28, 2015. The study aims at developing a fundamental and systematic understanding of the social media platforms to advance understanding of novel socio-technical behaviors, for example, hashtag activism, crowdsourcing, flash mobs, citizen journalism, “live-tweeting” or “tweetcasting” a crisis event, to support operational targeting and designing strategies to tackle such behaviors. “Efficient data analysis techniques are needed to provide open source intelligence (OSI) to support situation awareness, risk assessment, mission assessment, and an over all mission effectiveness,” Agarwal said. Agarwal has a Ph.D. in computer science from Arizona State University with outstanding dissertation recognition. His research expertise includes social computing and behavioral modeling, knowledge discovery and data miningextraction in Social Media and Web 2.0, modeling and evaluating phenomena social dynamics involving such as influence, trust, and collective action atfamiliar strangers, collective wisdom, and community discovery, largweb-e-scale data management, data mining, web mining, and privacy, as demonstrated by numerous highly cited articles in various reputed conferences and journals including best paper awards.
