ACCESS: An Adaptive Contactless Capacitive Electrostatic Sensing System

Alexander Nelson

10:30-12:30 Thursday, 13 July 2017, ITE 325, UMBC

Technological miniaturization and low-power systems have precipitated an explosive growth in capability and adoption of wearable sensors. These kinds of sensors can be applied to many medical and rehabilitative applications, including as an assistive interface. The overarching theme of this thesis is the development of fabric capacitor sensor arrays as a holistic, wearable, touchless sensing solution. These fabric sensors are lightweight, flexible, and can therefore be integrated into items of everyday use. Further, the capacitive sensing hardware is low-power, unobtrusive, and maintainable.

Additionally, gesture-recognition is expanded in this work to touchless capacitor sensor arrays through the ideation, development, and evaluation of an adaptive signal processing algorithm. The algorithm comprises a hierarchy of data reduction techniques that enable real-time processing on a low-power embedded microcontroller. Using a set of adaptive techniques, the system allows for recognition of gestures of different sizes and rotations as well as gestures with noisy or jittery motions. These adaptations enable a set of mobility that encompasses a large portion of people with upper extremity mobility impairments.

The system is developed as an assistive device, with application to environmental control as a Smart-Home controller.The research is conducted with advisement from medical professionals and private consultants, and evaluated in clinical trials by individuals with upper-extremity mobility impairment.

ABC features UMBC cybersecurity student scholars

Students at UMBC are learning how to hack into systems and prevent attacks. They study hardwarre, software and the tools in between.

 

Jamie Costello from ABC’s Baltimore affiliate WMAR has a short video feature, UMBC is on a mission to crack the code, on UMBC students who are studying and doing research on the cybersecurity of computing hardware, software and systems.

If you walk through your door and notice your home computer in pieces scattered throughout the house, call UMBC.

In the old days, parents wanted their children to grow up to become doctors and lawyers, now its about becoming cyber security experts.

A select group of students at UMBC knew this was for them. Some tore computers apart. Some knocked XBOX players off their game on purpose. And one student, while in high school and with the school’s blessing, hacked into the school’s security camera system.

Jobs are like gnats on a summer night, college graduates are swatting the offers away. And the pay is good, really good.

Students are learning how to hack into systems and then prevent such attacks. They are studying hardware, software and tools in between. The more we invent and tie into the internet, the more cyber security experts are needed.

Microsoft launches competition to create collaborative AI system to play Minecraft

 

A Microsoft Research team challenged PhD students to craft an advanced AI-based system that can collaborate with people in playing the popular Minecraft game, offering three $20K prizes. Minecraft was chosen because it offers an environment that, which relatively simple in some ways, it requires advances in areas that are still difficult for artificial computer agents to handle. The challenge asks questions like the following.

“How can we develop artificial intelligence that learns to make sense of complex environments? That learns from others, including humans, how to interact with the world? That learns transferable skills throughout its existence, and applies them to solve new, challenging problems?”

Microsoft’s Project Malmo addresses them by integrating deep reinforcement learning, cognitive science, and many AI ideas. The Malmo platform a sophisticated AI experimentation system built on top of Minecraft that is designed to support fundamental research in artificial intelligence.

A recentTechRepublic article, Microsoft competition asks PhD students to create advanced AI to play Minecraft, describes the competition and quotes UMBC Professor Marie desJardins on the project.

“Marie desJardins, AI professor at the University of Maryland, Baltimore County, sees Minecraft as an ‘interesting and challenging problem for AI systems, because of the fundamental complexity of the game environment, the open-ended nature of the scoring system, and the opportunity to collaborate with other game players (AIs or humans).’

But desJardins also raises concerns when it comes to these competitions. ‘Who owns the resulting intellectual property?” she asked. “Are these kinds of contests the best way for grad students to spend their time? Do these competitions foster or decrease diversity? Who ultimately profits from the contests?'”

The Malmo challenge is open to PhD students who register by April 14, 2017. After registration, teams of one to three members are given a task that consists of one or more mini-games. The goal is to develop an AI solution that learns how to work with other, randomly assigned players to achieve a high score in the game. Participants submit their solutions to GitHub by May 15, including a one-minute video that shows off the AI agent and summarizes what is interesting about their approach.

Attacking and Defending the Automotive CAN Bus

MS Thesis Defense

Attacking and Defending the Automotive CAN Bus

Jackson Schmandt

12:30pm Thursday, 8 December, 2016, ITE 325b, UMBC

The scope and complexity of Automotive Computer Networks have grown drastically in the last decade. Once present only in high end vehicles, multi-use infotainment systems are now included in base models of some economy vehicles. Frequently connected to drivetrain components, these systems bring out multiple network access points, many of which are wireless. This unprecedented access has led to several high-profile exploits from both white-hat hackers and criminals. Although industry members are working toward long-term solutions, current systems suffer from inadequate protocol security and a lack of common-sense design practices. To address the security problem in the short term, this thesis describes a flexible Message Authentication Code that can be retrofitted with software only, as well as implementations on microcontrollers, an FPGA and an ASIC design. This work shows that on current embedded controllers, message authentication tags can be generated or verified in under 400 microseconds and in under 10 microseconds on a special-purpose ASIC.
