Using Biometrics for Security :: Technology Safety Essays

Using Biometrics for Security Today the protection of everything has become an important issue that affects everyone. Whether it’s protecting a cashier’s cash drawer or preventing a suicide bomber onto an aircraft. Either way there is going to be an increase and change in security. The advancement in the technology of computers has made it easier for people to get information. Today, a person can log onto the internet and view information on anything and everything. If an average person can do that then how secure is the internet? How much security should be placed on a computer or a website? For the average person, a password, personal identification number, or keys allow them to view information that only they can access. This form of security isn’t of high-quality because it can be forged. Over the years, many people have developed security systems that can actually authenticate a person. This report will be looking at these advancements as well as my thoughts of them. The improvement in security was developed on the bases of biometrics. Biometrics refers to the authentication techniques that rely on measurable characteristics that can be automatically checked. [1] Biometric techniques are divided into physiological and behavioral characteristics. Physiological characteristics include: the finger, palm, the face, and the retina and iris of the eye. Behavioral characteristics include: voiceprints, keystrokes and handwritten signatures. Fingerprints is the most commonly use of biometric today. It works great for the population between the ages of 18 and 40 because their prints are haven’t been effective by normal aging. In my view there are a few downfalls. The first on is due to aging. As we go through life our body changes. We lose fat on a fingers causing the image to become more difficult to read. The second one is due to the type of employment. A construction worker or a carpenter work with their hands all the time. Many of them get injuries on their hands causing a scar to alter the fingerprint. My final downfall is a bit distorted. A finger can be cut off. There are many people that will go to any means to get what they want. This includes cutting off a person finger and carrying it around till they get to what they need to access. Palm and hand scanner are less effective and more expensive then fingerprint scanners.

Assignment The Solution

In this function is the population at time O, P is the population after time t, and k is called the exponential growth rate. For this problem about the population of rats, represents the rats population at O, P is the rats population after time t 7 days and 14 for 2 weeks as seen in and and k is the rats exponential growth rate which is represented by the 13. 6% or the decimal O. 136. Using this equation we calculate that in 1 week the rats have grown from 100 rats to 259 rats and in 2 weeks the rats have grown from 100 rats to 671 rats. The sat part of this problem asks us to find the doubling time of the population of the rats.The algebraic solution for this is represented by solving for T. The equation for this is and now I will tell you what it substitutes. We substitute 200 for and the rest of the equation uses the natural logarithm to solve for doubling time of the rats population. Some of the topics in this course this problem relates to are natural logarithms, exponential fun ctions, and graphing. These functions are applicable to the business, science, psychology and sociology fields. The Intersect method for this problem is used in the technology field. The answer from this problem states the population of rats will double in 2 weeks.Method The method of problem solving that I use is, I find another problem like this one and match the numbers up to the equation of the other problem, solve this problem parallel to the other problem following the guided steps, essentially multi-tasking, solving two problems at the same time. I call this method â€Å"Killing two birds with one stone. † Once I have worked both problems to their simplified form, I input this information into a calculator to arrive at y answer. The variety Of ways to solve this problem is through the use Of a calculator and the growth / decay formula.My rationale for selecting the method adopted is because like to keep things simple. Pre;calculus is complicated as it is. It would be e asy for me to overprint solving problems if I did not keep it simple. Also tend to not fully grasp the concepts unless solve the problems slowly and double checking my work. Explanation The easiest way can explain solving this problem to someone would be to patiently go through the problem step-by-step with them pausing along the ay making sure they are grasping the concepts of solving the problem.I would start by reading the word problem thoroughly, taking note of the numbers in the word problem. I would then use the exponential growth rate formula matching the numbers up to the equation and begin to solve the problem using P. E. M. D. A. S. It is a staple to any math problem. Certain rules apply that cannot be ignored. Will conclude this problem with assisting them through the doubling formula of to find its solution.Conclusion The solution to the population of rat's problem clearly states that using the exponential growth function, the rat's population after one week is 259 rats and the population doubles after two weeks giving us 671 rats. If my calculations are correct the 5 for T in the solution represents a 5 year mark? This solution Was derived by dividing the natural logarithm of Len by the percentage of 0. 136 in decimal form. Given this information it is possible to state that the rats population will double in size from 671 in two weeks to another greater number in 5 years. I will firmly agree that this solution is correct.

The Atomic Bomb - 1580 Words

Now, let’s go back to the not forgotten â€Å"four letter word†. â€Å"Gold† was the word our predecessors chose. With everything that comes with it including a bonus; an extra letter that figuratively speaking changed the spelling of gold to â€Å"Money†. Its weight, its vigor, had a big influence, and yes, its domination found the acceptance by the most who dedicated their lives to it. For the choice that was made we were hijacked. We see it and we pay the bills of their residual effects through wars, the atomic bomb, violence, crime, corruption, climate, nature, food, health, multinationals, and above all, our state of mind, including the psyche. Following our precursor s mistakes, we have created a false reality. Speeding as we are doing, we have no†¦show more content†¦The temporary victory, as the adjective denotes, won t last. To the contrary, the eternal one that can be achieved in spirituality has no monetary value. It doesn t require anything more than focusing on it with trust, in humbleness, and being appreciative for what we have, whether it is good or bad. This life’s status is of minor importance to the eternal. If we trust and say thanks sincerely, in any form we like, when we feel like it, the course of life will change in our favor. The Great Spirit is not vain, doesn t require idolatry, but unconditional love for the whole and respect sustained by the belief in the Higher Realms. Such a felt belief, when it is present has to be ever-present. Above all, never doubt it. Furthermore, if doubt exists, it should be truly examined and compared, then let flow into humble acceptance. This way to believe will allow us to fly spiritually and see the magnificence that has always been present for us, as part of us. Let s get back to Earth and our mistakes. We inherited a form of violence known as war. â€Å"The boy woke up in the middle of a revealing dream, picked up his guitar and begun to sing ‘We have to stop these men with the narrow mind, so afraid of themselves are seeking and living endless fights. We have to remind them that war, it’s a mistake of the past, we know that is their moneymaking we don’t need it, we don’t want that on our expenses, it will last.’†¦Ã¢â‚¬  From: â€Å"A Mistake of the Past†  © 1979 War will
