The goal of this project is to use our newly developed technology on anti-phishing to develop a Web service for effective and efficient phishing detection, for both enterprise users and end-users to timely and proactively detect phishing.
Named SiteWatcher, our solution is a Web Service based on cloud computing to automatically, accurately, and immediately identify if a given URL points to a phishing webpage and find the legitimate webpage it is attacking (its phishing target). We will decompose our system into a few modules and keep the kernel module at our servers while deploying other modules (requiring large bandwidth and intensive computation) to cloud servers. We may also develop plug-ins and APIs for enterprise users' various Web applications (including Web browsers, search engines, Email readers/servers, online shopping websites, and online advertisement management websites, etc.). End-users can also submit suspicious URLs to our service to check detection results.
Our solution is the first and so far the only one which can detect phishing target in the world and can detect more than 99% phishing cases within a few seconds to a few minutes, much better than existing browser's phishing detection accuracy and efficiency. For example, Microsoft IE can detect only 40% phishing cases within 7 days and the average time to detect a phishing case is more than 24 hours. With cloud computing, we believe we can further improve our system's efficiency. Hence we believe our solution can dramatically reduce the number of victims of phishing once deployed.
The enhanced luminous efficacy of blue light-emitting diodes (LEDs) would improve the luminous efficacy of white LEDs for solid-state lighting. In a typical blue gallium nitride (GaN) LEDs structure, the planar transparent conducting oxide (TCO) thin film acts as transparent contact electrode (TCE), and helps extract photons with its high optical transmittance. However, conventional TCE thin film, such as indium tin oxide (ITO), has limited utilization in future optoelectronic devices because of the rising cost of indium, its toxicity, poor chemical stability, and n-type conduction property. Thus, the development of new, low cost, environmentally-friendly, and p-type conduction TCO materials will significantly benefit the production of high luminous efficacy blue GaN LEDs.
This proposed research aims to verify the stability of blue GaN LEDs with high luminous efficacy for integration in white LEDs used in residences, offices, and general lighting applications. The proposed blue GaN LEDs will contain a novel feature: composite TCO thin film (cTCO film) acting as TCE. The cTCO film will be optimized in the thermal annealing process, possessing low contact resistivity, high optical transmittance, and high chemical stability. Then, reliability of the blue GaN LEDs utilizing the cTCO film will be investigated. The proposed research is an extension of our previous work and demonstrates the validity of the concept in practical applications.
Ubiquitous Computing is a post-desktop model of human-computer interaction in which information processing has been extensively integrated into everyday objects and activities. On the other hand, Intelligence Devices (e.g., smart phone, tablet, 3D TV etc.) are now becoming substitutes for the desktop computers. Hence, the traditional input devices of desktop computers such as the keyboard may someday completely be replaced by small and ubiquitous input devices. Therefore, human-to-computer natural interaction input devices play an increasingly crucial role to 3D user interface for mobile devices and digital home systems, and other fringe applications such as scientific visualization, virtual reality, and multimedia systems.
For this project, we propose to develop a novel Ubiquitous 3D Input System based on MEMS motion sensing and computer vision technologies. This novel human-to-computer interactive device aims to capture human hand-writing or drawing motions in real-time and also communicates with a computing platform (i.e., an iPad, iPhone, for labtop PC, etc.) to process the human motion trajectories for character recognition. Products which aspire to capture the new market of ubiquitous input devices for mobile applications have begun to surface commercially but most of them are still limited to only 2D interactive space, and also are hampered by at least three problems: 1) requirement of specialized and bulky accessories (e.g., special whiteboards or papers are need) that hinder the technologies for becoming highly popular; 2) cannot provide long-term stability with inertial measurement unit (IMU) technology due to inertial sensors' integration and random noise errors; 3) relative high cost of the products which makes them inaccessible to many professional or home users.
The proposed system will allow end-users to have the total freedom of interacting with computing devices in 3D space ubiquitously, i.e., they can use the system anywhere and on any surface, without the need for specialized papers or whiteboards, or being constrained to only creating their input to computing device in 2D space. Within 12 months, our team will demonstrate a 3D Digital Input System that has a geometry similar in shape and size as a conventional whiteboard marker and with the associated software tools for sensor fusion and for hand-gesture motion tracking and recognition.
Hard coatings provide the modern cutting tools with wear resistance and protection against the heat generated at high cutting speeds. Nowadays a challenge for tool suppliers is to increase the tool productivity and reliability in order to meet the increasingly stringent requirements of modern manufacturing industry. The present research project includes the synthesis, characterization and field tests of superhard nanocomposite nitride coatings deposited on cutting tools including high-speed steel and cemented carbide. These novel coatings will be prepared by a new integrated PVD process. Mechanical, tribological and chemical properties of the coatings, such as hardness, friction coefficient, wear-resistance, thermal stability and oxidation resistance, will be studied, and the cutting performance of the coated tools will be evaluated. The feasibility to fabricate these coatings in an industrial scale will be explored.
