According to the radiation experts and medical physicists body scanners which use at airports don’t cause real health risks .But effectiveness of body scanners depends on the amount of radiation dose, frequency and the duration a person expose to it.
Airports use two types of scanning technology -- millimeter wave scanners, which use radio waves and do not expose people to X-rays, and backscatter scanners, which use very low levels of X-rays.
It's the backscatter scanners -- which create an anatomically accurate image that reveals if anything is hidden under a person's clothing -- that have been the subject of controversy in the past week.

Also there should be more specialized body scanners for sensitive body parts such as eyes. If not safety equipments should be worn to cover those parts as safety glasses can be used to cover eyes. The affect to the children is another considerable issue with body scanners. As their internal organs (such as kidneys) are still building and tenuous they can be damaged easily. Also high dose of radiation can cause distortion. In the case of whole body CT scanning it is difficult to justify medical examinations that involve large radiation doses which may be of little benefit to the patient. Whole body scanning currently offered in Sydney imposes large radiation doses on clients in the range of 4 to 24 millisieverts (mSv) per scan. In comparison, a chest x-ray gives an average dose of 0.04 mSv.
The Department of Health has advised that a whole body CT scan with an effective dose of 10 mSv may be associated with an increase in the possibility of cancer of approximately 1 in 2000. This cancer risk generally outweighs the potential health benefits for healthy people under the age of

...Keiah Vail Professor: Seitu Stephens COM/156 April 29, 2012 Research Paper: Airport Security Airport security includes the procedure of guarding public transportation by airplane, as well as the terminals from which passengers of aircraft arrive and depart. Airport security has drawn the attention of the American public for invasive pat-downs, body scans and various news reports on concerns from TSA on failures to catch contraband items. A lot of people often wonder what is the reason for pat downs and body scans. Pat-downs are used to resolve alarms at the checkpoint, including those triggered by metal detectors and units. Pat-downs are also used when a person chooses out of screening in order to detect potentially dangerous and prohibited items. Because pat-downs are specifically used to resolve alarms and prevent dangerous items from going on a plane, the vast majority of passengers will not receive a pat-down at the checkpoint. All passengers have important rights during a pat-down. You have the right to request the pat-down be conducted in a private room and you have the right to have the pat-down witnessed by a person of your choice. All pat-downs are only conducted by same-gender officers. The officer will explain the pat-down process before and during the pat-down. Instead of making everyone strip down, the TSA has organized a type of body scan screening machine that let passengers skip the undressing part. The machine “undresses” you by using either x-rays or millimeter...

Upon understanding some of the biometrics differences and earlier methods used, I think the world is definitely is a better place to live in, as well as a much safer world to be in. One example of how this was used to make the world a better place was where biometrics were used at the NFL Super Bowl game in Tampa, Florida. There are many different types and ways of using biometrics to prevent entry into certain places or even to catch criminals from further causing damage in society. Biometrics is the overall study of measurable characteristics, specifically in computer security biometrics refers to the different authentication techniques that rely on measurable physical characteristics that can be automatically checked. The overall practice of distinguishing humans based on intrinsic physical or behavior traits goes back thousands of years. The purpose of this term paper is to review and analyze several different methods of biometrics, including the evolution and...

Design and Implementation of a Bio-Metric (Fingerprint) Clocking System

...CHAPTER ONE INTRODUCTION 1.0 BACKGROUND TO THE STUDY Staff attenda nce management of an institution or organization can be very laborious using the conventional method of paper sheets and old file system method. Every corporate organization poses some standards concerning how attendance is to be confirmed for staff in offices. This is to enable the management of the organization identify those staff that are punctual and competent, that is why keeping the accurate record of attendance is very important. Also in institutions, tracking and monitoring staff time of attendance could pose a tedious task, time consuming and as well prone to errors. As an alternative to the traditional manual clocking process by staff in offices, biometrics characteristics can be used for authenticating staff. This research will focus on developing a Fingerprint based Biometric Clocking System.  The fingerprint Biometrics is adopted in this research work due to the fact that it is one of the most successful applications of biometric technology. In the manual signing processes, where a sheet of paper is placed at the entrance of the office for staff to write their names and signature as a form of confirming their presence for a particular day in the office, falsification in staff attendance mostly occur. A situation whereby a staff can sign on behalf of his or her colleague as being present in the office when that is not true. This can be so difficult to prevent from happening especially for large...

...System Engineering Management ROBOT PAINTING USING ARTIFICIAL INTELLIGENCE SUBMITTED BY Hari priya Kapileswarapu 1504606 ADVISOR Steven Maher; Geoffrey Rodman OKLAHOMA CHRISTIAN UNIVERSITY ABTRACT: This paper describes about one the functionality of the robot and how robot paints an object using artificial intelligence. And objects like iron wall, wooden box, motor bike etc. Suppose if the robot has to paint a motor bike it has to identify the parts of the motor bike and has to paint the color to those parts. For example, if the rims of the wheels had to be painted in black color then the robot has to identify the rims and paint the black color. In the same way, if the chassis had to be painted with black color then the robot has to identify the chassis and paint it accordingly. In this way, the whole motor bike would be painted by the robot based on the parts. For painting the parts of the motor bike there are some methods like generating the optimum path and the trajectory methods. In this way, robot can paint the respective object based on the models with different colors.

...LA, U.S.A. McAfee Avert Labs, Beaverton, OR, U.S.A. arun@louisiana.edu rachit_mathur@avertlabs.com mohamed@louisiana.edu walenste@ieee.org ‡ † Abstract: A design space is presented for metamorphic malware. Metamorphic malware is the class of malicious self-replicating programs that are able to transform their own code when replicating. The raison d'etre for metamorphism is to evade recognition by malware scanners; the transformations are meant to defeat analysis and decrease the number of constant patterns that may be used for recognition. Unlike prior treatments, the design space is organized according to the malware author's goals, options, and implications of design choice. The advantage of this design space structure is that it highlights forces acting on the malware author, which should help predict future developments in metamorphic engines and thus enable a proactive defence response from the community. In addition, the analysis provides effective nomenclature for classifying and comparing malware and scanners. Keywords: Metamorphic Malware, Virus Scanner. 1. Introduction Metamorphism is the ability of malware to transform its code. This ability was first introduced in viruses and was later used by worms, Trojans, and other malware. There now exist several metamorphic engines—programs that implement only the logic for transforming code—that can simply be linked to any program to make it metamorphic. Metamorphic malware can be classified into four broad groups...
