...Magnetic Swipe Card System Security A case study of the University of Maryland, College Park Daniel Ramsbrock dramsbro@umd.edu Stepan Moskovchenko stevenm86@gmail.com Christopher Conroy cconroy@gmail.com Abstract This paper provides a comprehensive security analysis of the Lenel magnetic swipe card system used at the University of Maryland at College Park. We first explore the cards and hardware components which comprise the system, and then present several plausible points and methods of attack on the system. We chose several of these attacks and demonstrated them using a $240 commercial card reader/writer and a customized unit powered by a microcontroller, which cost about $20 in parts. We developed the capability to read cards, write arbitrary data to cards, simulate card swipes through a reader using a flux reversal pattern generator, and “sniff” data from up to 16 live swipes using a single microcontroller which can be easily hidden in the reader's housing. We tested and successfully demonstrated these capabilities on the live Lenel system under the supervision of the university's Department of Public Safety. Based on our findings, we recommend that the university use neither social security nor university ID numbers on the cards, that it use magnetic card access only in low-security areas, and that it use a more sophisticated and secure system such as proximity smart cards for access to high-security areas. While the analysis and recommendations presented in...

...INTRODUCTION MAGNETIC LEVITATION TRASPORT, OR MAGLEV, IS A FORM OF TRANSPORTATION THAT SUSPENDS, GUIDES AND PROPELS VEHICLES VIA ELECTROMAGNETIC FORCE Air flights are and will remain beyond the reach of a major section of society, particularly in India. Moreover there are problems of wastage of time in air traffic delays and 2 growing safety concerns. Trends in increased mobility of large masses with changing lifestyle for more comfort are leading to congestion on roads with automobiles. Besides, increasing pollution levels from automobiles, depleting fuel resources, critical dependence on the fuel import and due to a limited range of mobility of buses and cars the need for fast and reliable transportation is increasing throughout the world. High-speed rail has been the solution for many countries. Trains are fast, comfortable, and energy-efficient and magnetic levitation may be an even better solution.Development of magnetic levitated transport systems is under progress in developed countries and it is just a matter of time they make inroads to India as well. Therefore, it will be interesting to know about the science and technology behind mass ground transport system known as "magnetic flight". A LITTLE HISTORY In 1922 a German engineer named Hermann Kemper recorded his first ideas for an electromagnetic levitation train. He received a patent in 1934 and one year later demonstrated the first functioning...

...ch y Psychology can assist law enforcement by profiling criminal suspects assessing in truthfulness of suspects and evaluating the validity of their confessions. Psychological theory and techniques can be used to improve police officers evaluations of criminal suspects. * Profiling is usually performed at the beginning of criminal investigation when the police need help focusing on certain types of people who might be the suspect * Once a suspect has been identified law enforcement officials use other procedures to determine whether any of them should be charged. * Police look for visual and verbal cues to determine whether they are giving truthful responses Suspects are sometimes given a lie detector test to encourage them to confess. * The tests provide more information about their guilt or innocence. * They conflict with some psychological findings about their accuracy. * Sometimes they are submitted into evidence. * Many psychologists question the validity of the test. The police interrogate suspects and encourage them to confess because the confessions make it more likely that suspects will successfully prosecute and eventually convicted the suspects. Psychological finding often conflict with the courts evaluations of a voluntary confession. There is some evidence psychological characteristics are linked to behavioral patterns and they can be detected by a psychological analysis of crime scenes. * Criminal profiling is used to...

...MAJOR PROJECT LASER TORCH BASED VOICE TRANSMITTER AND RECEIVER CHAPTER -1 INTRODUCTION 1.1 ABOUT PROJECT LASER TORCH-BASED VOICE TRANSMITTER AND RECEIVER Using this circuit you can communicate with your neighbors wirelessly. Instead of RF signals, light from a laser torch is used as the carrier in the circuit. The laser torch can transmit light up to a distance of about 500 meters. The phototransistor of the receiver must be accurately oriented towards the laser beam from the torch. If there is any obstruction in the path of the laser beam, no sound will be heard from the receiver. The transmitter circuit comprises condenser microphone transistor amplifier BC548 (T1) followed by an opamp stage built around µA741 (IC1). The gain of the op-amp can be controlled with the help of 1-mega-ohm pot meter VR1. The AF output from IC1 is coupled to the base of transistor BD139 (T2), which, in turn, modulates the laser beam. The transmitter uses 9V power supply. However, the 3-volt laser torch (after removal of its battery) can be directly connected to the circuit—with the body of the torch connected to the emitter of BD139 and the spring-loaded lead protruding from inside the torch to circuit ground. The receiver circuit uses an npn phototransistor as the light sensor that is followed by a two-stage transistor preamplifier and LM386-based audio power amplifier. The receiver does not need any complicated alignment. Just keep the phototransistor oriented towards the remote transmitter’s...

...EFFECTS OF TELEVISION ON SOCIETY | | | EFFECTS OF TELEVISION ON SOCIETY Television broadcast has broad effects on the society all around the world. The strong verbal and non verbal combination and the facility to highlight different subject matters created one of the most important impressions in mass media. There are so many angles to see as to what extent TV has brought about changes in daily life of people and the nations as well. Here we will see some of the key changes affected by TV transmissions in general. Seeing is believing The authenticity of news and other informative material has never been more acceptable to people through other means of communication than the one available on TV. People already informed about an event still like to see the news along with footage on TV. For instance, the winning run scored by your favorite team in an exciting match is something people would like to see again and again although they know the outcome of the match. So is about visuals on accidents and unusual events like hanging of Iraqi leader Saddam Hussain etc. Changes in timings Most people have tuned their daily timings in accordance with their popular programs. Students tend to finish their homework before their favorite show. Housewives would make their cooking schedule as not to miss the soap tonight. Men would get ready for relaxing by watching programs of their interest. Much noticeable change is in bed-timings. Early to bed... dictum seems to have...

...Chapter 1 INTRODUCTION Background of the study Living in this modern society, technology is very much involved. Every person is recognized with the device or gadget, he carries; that is the result of a technologically inclined society. Eventually, living without technology is like a soldier without gun; that is how people are so much dependent with technology today. Nowadays, some customers such as hospitals, manufacturing, industries, commercial establishments, schools, buildings and homes are dependent on electrical devices and equipment. These devices are controlled by modern technology for their operations, controls and processes. This includes remote sensing, SCADA, HMI, micro controller sensors and PLC. They are used for automatic control of lights and switches, and for remotely controlled operation of equipment or machine. These modern technologies save time, costs, and labor. The researcher conceptualized this study about the modern technology using HMI in the school specifically the laboratory room. Laboratory should be conducive to learning so that students are encouraged to study. It is a room where the students have the basic knowledge in theoretical aspects before they ought to gain knowledge outside. So, the study is focus on the development of a modernized laboratory equipped with automatic controls. Before laboratory is just a room with equipment, many lights, and switches. They are using manual switching of the facilities inside a laboratory room which is done...
