Active Behavior as a 4th Dimension for Identity Authentication

Identity Gains Greater Importance in Era of Terrorism

Computerized identity authentication systems (CIAS) have traditionally been based on 3 independent concepts:

  1. What you know (passwords, PINs),
  2. What you have (Smart Card, ID badge), and
  3. What you are (biometric and natural behavior systems).

A fourth authentication concept incorporates deliberate perturbation of natural behavior in an authentication test, which may provide an inexpensive dimension to the authentication process. Research under way is focused on determining whether such a technique could be used to advantage without incurring an excessive penalty.

Several disadvantages need further exploration. The research process invokes comparisons of theoretically developed active behavior versus the real world environment. Using an Active Behavior Test Bed revealed a practical entropy significantly lower than that calculated by probability calculations. Future research will explore practical entropy limits and correlations.

George Washington University information security researchers consider authentication system effectiveness in terms of vulnerability to attacks, effect on human factor vulnerabilities, and effects on authentication entropy. Entropy is an information technology concept that provides a measure of the theoretical uncertainty associated with guessing a password, etc. The George Washington University Information Security Group has developed and studied a system called Time Domain Sensitive Password Protection, which shows promise for providing protection from various forms of attack.

Dr. Christopher Hekimian is the research director for Adams Security Research Associates, LLC. He received the Ph.D. degree in systems engineering management at GWU in 2004. He earned the MSEE degree in 1955 at the California Polytechnic University in Pomona. Dr. Hekimian is the founder of DXDT Engineering & Research, LLC. He has three patents-pending on techniques for the security of biometric authentication systems and has a patent pending for a TV-interactive technique.

The Alfred T. C. Chang Memorial Symposium (Sponsored by W/NV GRSS)

Dr. Alfred T. C. Chang, IEEE Fellow, graduated with a degree in physics from National Central University in Taoyuan, Taiwan. He then received his M.S. and Ph.D. degrees, also in physics, at the University of Maryland. He was employed by NASA at Goddard Space Flight Center from 1974 until his death on May 26, 2004.

Dr. Chang's main area of research was the use of microwave instruments for remotely-sensing properties of the atmosphere and land. Most of his illustrious career was spent on analysis of microwave data of snow cover and rainfall, and he produced several seminal papers on these subjects, beginning in the '70s, that are still being referenced today. Dr. Chang published more than 100 journal articles, and among his many honors and awards is the NASA Medal for Exceptional Scientific Achievement.

HOE Scanning Lidars and Applications

The scanning of large aperture (~1 m diameter) telescopes is a major challenge for satellite-based lidar remote sensors. It also greatly complicates and constrains the design of airborne lidar systems. Lidar telescopes based on holographic optical elements (HOEs) offer a much simpler means of employing scanning, reducing size and weight without sacrificing instrument performance. NASA has developed and investigated the use of HOEs for scanning lidar telescopes. Two atmospheric lidar systems based on this technology have been built and used in a number of atmospheric science investigations. Future developments may employ multiplexed HOEs to effect scanning without moving parts.

Geary K. Schwemmer joined NASA GSFC as a research electronics engineer in 1977. His first project was a big one and took more than 15 years. He was the lead engineer (and the only one that stayed with the project for its entire duration) in an effort to develop a Differential Absorption Lidar (DIAL) system for measuring atmospheric pressure and temperature profiles using oxygen A band absorption features. It involved building three complete lidar systems, each using progressively more complex tunable near IR lasers as the state of the art evolved. The last generation O2 DIAL involved the first application of the newly developed alexandrite laser, the first widely tunable solid-state laser. During the course of that project, he designed and built tunable alexandrite lasers, laser wavemeters and spectrometers.

Three Mile Island in Historical Perspective

On this 25th Anniversary of the worst accident involving a nuclear power plant in the United States, it is important to understand what actually occurred at Three Mile Island. The event which began at 4:00 a.m. on March 28, 1979 was watched by the entire world.  Authorities at the highest level were called  to the crippled plant as they as they sought to prevent the emission of dangerous quantities of ionizing radiation into the environment. Sam Walker will provide an analysis and overall perspective of the human drama that unfolded on that fateful day and for the weeks and months that followed the accident.  He will provide a clear picture of the human drama that surrounded the accident while placing it in the context of the intense debate that was occurring over the benefits of using nuclear power for the generation of electricity. The presentation will cover questions relating to studies of  the long-term health effects from the accident and will offer a unique perspective into the issues of dealing with a critical event in today's world.

J. Samuel Walker is the official historian of the United States Nuclear Regulatory Commission.  He has held academic positions at Georgetown University and the University of Maryland.  He is the author of numerous publications.  Previous books include "Permissible Dose: A History of Radiation Protection in the Twentieth Century" and "Containing the Atom: Nuclear Regulation in a Changing Environment."

Making A Many-Colored Processing Engine: Signal Processing with Optical Filters

The ultimate information capacity of optical fibers is far beyond currently deployed systems, even with the exponential growth in system capacity over the past 20 years. Even now, the performance of high-capacity, long-distance wavelength- division-multiplexed (WDM) networks depends significantly on reconfigurable optical filters for bandwidth management and adaptive filters for compensating analog impairments. Optical filters are also key elements in optical code generation and detection with applications in optical packet header processing. Whether the end goal is for communications or high-speed signal processing, optical filters that can operate on amplitude, phase and polarization are critical to unleashing the full potential of optical systems. To be practical, a cost-effective implementation that can scale in optical circuit integration density and functionality is required.

This talk addresses optical filters in the context of their analog and digital relatives. Dr. Madsen will show how well-known filter types are related to the underlying interference mechanisms and how digital filter theory concepts are beneficially translated to the optical domain. Then, the present capabilities of integrated optics for implementing adaptive optical filters and an overview of some challenges ahead will be discussed. Adaptive filters implemented using high-index-contrast silica-on-silicon planar waveguides with applications to tunable chromatic dispersion compensation and polarization monitoring, control and polarization mode dispersion compensation will be used as examples. With state- of-the-art integrated optical filters, we have the ability to realize a many-colored, high-speed and cost-effective processing engine that truly harnesses the power of photonics.

Dr. Christi K. Madsen is a distinguished member of the technical staff at Bell Laboratories, Lucent Technologies, an IEEE Senior Member, and an OSA Fellow. She received a B.S.E.E. from the University of Texas at Austin in 1986, a M.S.E.E. from Stanford University in 1987, and her Ph.D. degree from Rutgers University in 1996, all in electrical engineering.

She joined AT&T Bell Laboratories in 1987 and worked first for the submarine systems business unit, then transferred to the integrated photonics research department. Her research has focused on the application of digital filter and signal processing techniques to optical filters for high-speed, high-capacity optical communication systems. In 1998, Dr. Madsen invented a class of tunable, multi-stage optical allpass filters that allow any phase response to be approximated and have application in chromatic dispersion compensation and polarization mode dispersion compensation. She holds 14 U.S. patents and has presented more than 70 technical talks and papers.

Imaging in the THz: Technology and Applications

“Since we have become accustomed to think of waves of electrical energy and light waves as forming component parts of a common spectrum, the attempt has often been made to extend our knowledge over the wide region which has separated the two phenomena and to bring them closer together.” [Rubens, H. & Nichols, E. F., Phys. Rev. 4 (1897) 314–323]. More than a century after these words were written, the terahertz (1012 Hz) still remains the most immature and underutilized part of the electromagnetic spectrum.

This talk will discuss some of the potential applications for which the THz might be most useful and describe some of the key component developments which must be made in order to exploit the THz for commercial and government applications. In particular, the concept of THz imaging for remote sensing will be considered. Despite its generally limited atmospheric propagation, the THz has the potential to provide sensor information in IR-blind conditions (e.g., fog, rain, dust, smoke). Furthermore, THz imaging could offer clear advantages over conventional (i.e., MMW) all-weather imaging approaches. A current DARPA program, Terahertz Imaging Focal Plane Array Technology (TIFT), is focused on the development of such a class of sensors. Component technologies that are being addressed include high power sources, detectors, and integration technologies. Such technologies stand not only to revolutionize THz imaging, but will also find wide applicability to other emerging THz applications.

Dr. Mark J. Rosker joined the Defense Advanced Research Projects Agency in July 2003. Dr. Rosker came to DARPA from NASA's Jet Propulsion Laboratory (JPL) in Pasadena, CA, where he was a member of the Submillimeter Wave Advanced Technology Group. Dr. Rosker is the author of more than 70 technical papers and conference proceedings.

A Flexible Rapid-Prototyping System for High Power Converters

Although digital controllers offer an enormous benefit to power electronic designers for they are far from perfect. In some cases moving to a digital controller just trades one set of design problems for another. Fixed point controllers require work on the front end to determine scaling factors, and if the right debug tools are not available, then information about the system can be hidden from the designer. Mr. Smith will discuss a system for using a MATLAB target PC as a closed-loop controller in a power electronics circuit. The key piece is a Power Interface Board which uses an FPGA to tie the power system to Matlab’s controller. He will explore the unparalleled ease with which controllers can be developed using this system and will give examples of the complex systems it is capable of producing.

Chris Smith graduated from Virginia Tech with a B.S.E.E. in computer engineering in the fall of 2001. His interest in hybrid vehicles brought him to the power electronics field where he worked on his masters degree in electrical engineering also at Virginia Tech. With a strong computer background he primarily concentrated on implementation of control systems for power electronics. His experience in motor drives, high power conversion, microprocessors, and fuel cells totals more than four years.
