Breaking Into The Vault: Privacy, Security And Forensic Analysis Of Android Vault Applications, Xiaolu Zhang, Ibrahim Baggili, Frank Breitinger
Electrical & Computer Engineering and Computer Science Faculty Publications
In this work we share the first account for the forensic analysis, security and privacy of Android vault applications. Vaults are designed to be privacy enhancing as they allow users to hide personal data but may also be misused to hide incriminating files. Our work has already helped law enforcement in the state of Connecticut to reconstruct 66 incriminating images and 18 videos in a single criminal case. We present case studies and results from analyzing 18 Android vault applications (accounting for nearly 220 million downloads from the Google Play store) by reverse engineering them and examining the forensic artifacts …

Modeling Autonomous Vehicles Through Radio Controlled Cars, Eva S. Chen
Modeling Autonomous Vehicles Through Radio Controlled Cars, Eva S. Chen
Computer Engineering
Autonomous vehicles have a lot of potential in improving people’s everyday lives. They could reduce congestion, reduce collisions, enhance mobility, and more. But with these benefits come security and privacy risks. In order to research and test some of these risks, we are building a set of scale autonomous cars that can model autonomous and collaborative behaviors. One such behaviour would be platooning, where a group of vehicles can travel closely together at high speeds by following a lead car. We are doing this with various sensors and control algorithms to allow for future modularity.
Rules Based Analysis Engine For Application Layer Ids, David Scrobonia
Rules Based Analysis Engine For Application Layer Ids, David Scrobonia
Master's Theses
Web application attack volume, complexity, and costs have risen as people, companies, and entire industries move online. Solutions implemented to defend web applications against malicious activity have traditionally been implemented at the network or host layer. While this is helpful for detecting some attacks, it does not provide the gran- ularity to see malicious behavior occurring at the application layer. The AppSensor project, an application level intrusion detection system (IDS), is an example of a tool that operates in this layer. AppSensor monitors users within the application by observing activity in suspicious areas not able to be seen by traditional …

Who R U? Identity Theft And Unl Students, Marcia L. Dority Baker, Cheryl O'Dell
Information Technology Services: Publications
How can academic institutions help educate their students about the risks of identity theft? Or teach students to better understand how one’s online presence can hold so much joy and angst? For one campus, the University of Nebraska–Lincoln, the opportunity came from a middle school teacher engaging his students in a future problem-solving activity. UNL had the opportunity to create a 45-minute presentation on identity theft for local public school students who would be spending the day on campus researching this topic.
While preparing the presentation, we realized a top 10 list on identity theft for UNL students would be …
Development Of A Remotely Accessible Wireless Testbed For Performance Evaluation Of Ami Related Protocols, Utku Ozgur
Development Of A Remotely Accessible Wireless Testbed For Performance Evaluation Of Ami Related Protocols, Utku Ozgur
FIU Electronic Theses and Dissertations
Although smart meters are deployed in many countries, the data collection process from smart meters in Smart Grid (SG) still has some challenges related to consumer privacy that needs to be addressed. Referred to as Advanced Metering Infrastructure (AMI), the data collected and transmitted through the AMI can leak sensitive information about the consumers if it is sent as a plaintext.
While many solutions have been proposed in the past, the deployment of these solutions in real-life was not possible since the actual AMIs were not accessible to researchers. Therefore, a lot of solutions relied on simulations which may not …
A Particle Swarm Optimization And Block-Svd-Based Watermarking For Digital Images, Falgun Thakkar, Vinay Kumar Srivastava
A Particle Swarm Optimization And Block-Svd-Based Watermarking For Digital Images, Falgun Thakkar, Vinay Kumar Srivastava
Turkish Journal of Electrical Engineering and Computer Sciences
The major issues in most watermarking schemes are security, reliability, and robustness against attacks. To achieve these objectives in a watermarking algorithm, the selection of a scale factor to embed the watermark into the host image is a challenging problem. In this paper, a block singular value decomposition (SVD)-based reliable, robust, secure, and fast watermarking scheme is proposed that uses particle swarm optimization (PSO) in the selection of the scale factor. SVD is applied here on the nonoverlapping blocks of LL wavelet subbands. Selected singular values of these blocks are modified with the pixel values of the watermark image. Selected …

Proposing A New Clustering Method To Detect Phishing Websites, Morteza Arab, Mohammad Karim Sohrabi
Turkish Journal of Electrical Engineering and Computer Sciences
Phishing websites are fake ones that are developed by ill-intentioned people to imitate real and legal websites. Most of these types of web pages have high visual similarities to hustle the victims. The victims of phishing websites may give their bank accounts, passwords, credit card numbers, and other important information to the designers and owners of phishing websites. The increasing number of phishing websites has become a great challenge in e-business in general and in electronic banking specifically. In the present study, a novel framework based on model-based clustering is introduced to fight against phishing websites. First, a model is …
