Difference Between Searchmetric Systems And Locimetric System

Biometrics is defined as “the measurement and statistical analysis of people 's physical and behavioral characteristics” (“Biometrics”, n.d.). Examples of physical characteristics include: fingerprints, palm prints, facial features/patterns, DNA, thermal patterns, etc. Examples of behavioral characteristics include: voice recognition, typing habits, handwriting samples, signatures, etc. (“Biometrics Law”, n.d.). Two sole purposes of biometric systems are “identification and authentication” (Coleman, 2000) which can be used for a variety of reasons.

2) How is testing a complex system different from testing a complicated or a simple system?

Biometrics technology aims at utilizing major and distinctive characteristics such as behavioral or biological, for the sake of positively indentifying people. With the help of a combination of hardware and specific identifying sets of rules, a basic human attribute, automated biometric recognition mimics to distinguish and categorize other people as individual and unique. But the challenges surrounding biometrics are great as well.

The thing with biometrics is that it works great only if the verifier can verify two things: Firstly, that the biometric to be used has come from the intended person at the time of verification, and Secondly, which the biometric should match with the master biometric entry in the file database. If the system can't do that, it can't work. Biometrics are good in uniquely identifying the people, butat the same time they are not secrets and cannot be trusted [1].

Picture CAPTCHA – This type of CAPTCHA consists of random images and the user will be asked to select a particular phot that proves that user is a human and user is asked to click on one or more picture to prove that user is human. For a computer program it would be difficult to identify the contents of an image. For example, in the picture below the user is asked to identify which image contains a flower.

Biometrics is a method of identifying an individual based on characteristics that they possess, typically physiological features such as a fingerprint, hand, iris, retina, face, voice, and even DNA. Some methods of biometrics security even use multiple physiological features or multimodal biometrics to provide superior security than a single form of biometrics can provide. Why are biometrics important in the field of information security? Biometrics provide a remarkable amount of security for information because biometrics are unique to each person, and thus cannot be lost, copied, or shared with another individual. This security allows for biometrics to provide a means to reliability authenticate personnel. The importance of biometrics can be further divided into the history of biometrics and why it was devised, past implementations of biometrics, current implementations of biometrics, and future implementations of biometrics.

Biometric Authentication refers to the usage of software that looks for physical markers to allow access to a system. Some of the most commonly used physical markers are fingerprints, face-recognition, voice-recognition, and iris-recognition (Williams & Sawyer, 2015). As no two humans are exactly alike biometics are less likely to be hacked, although it is not impossible.

The next step option to further prevent this security will involve restricting access to data by requiring a password, personal identification numbers, or a callback procedure. This approach will restrict logon time to a maximum of 2 minutes; if the computer goes idle for 2 minutes, a login password will be required to gain access to the system. The only problem with previous approach will the redundant need to frequently reenter password, to alleviate this problem associated with redundant authentication, the organization can adopt the use of a biometric method of authentication, for example, the use iris scanner, fingerprint, or an electronic signature (Joos et al, 2010).

A Picture Pass Doodle is designed to provide sufficient security, usability, memorability, and interoperability across devices. The combination of free-form doodles and a background image separates the Picture Pass Doodle from other related works. Free-form doodles can provide greater and can also allow users to be creative. The background image used in Picture Pass Doodles increases memorability by providing cues and reducing the memory load on users. Finally, we can say regarding to the participants results that the Picture Pass Doodle system is a usable and secure system despite taking more time and steps during the registration and login stage. Picture Pass Doodle is a promising login and password protection criteria for the future and therefore further research could be done on the same so that the process becomes more efficient for easy application considering the fast technological development in the world

There many types of biometrics that are known to have success within organizations and government agencies. Some these types include smart card, fingerprint recognition, retinal/iris scanner, hand geometry, and facial recognition. All these types are known to be the most common types but one most also know that just like any other technology, each have their advantages and disadvantages. For example, smart card and fingerprint recognition are the most widely used due to them being cost effective and user friendly. The retinal/iris scanner are very secure but can be expensive to some. Although these technologies can be combined such as the smart card and fingerprint recognition, such as by having an individual insert has smart card into the reader which then will require that individual to place his/her finger on a scanner for a reading. Now let’s use the technologies in a example for access control of the facility that may be best to improve security while also considering cost. First is to implement the smart card which contains an integrated circuit chip. These smart cards work like an identification card but contain a circuit chip that allows for the storing of personal information, photograph of the person and biometrics like

Charlie likes Alice’s picture-password system of the previous exercise, but he has changed the login so that it just shows the user 40 different pictures in random order and they have to indicate which of 20 of these are from their set of favourites. Is this an improvement over Alice’s system? Why or why not?

Face recognition is another biometric technology. Face recognition uses the same technology that iris recognition uses. For face recognition, a camera takes several images of a person to find out who it is. Face recognition differs from all of the other biometric technologies because the person that is in the picture does not have to cooperate with the process. In all of the other technologies it requires the people to actively participate in the process. In face recognition, the image can be taken without the person even knowing that it took place.

A parabola and a hyperbola are two of the same, but also are very different. The definition of a conic section is a section (or slice) through a cone. By taking different slices through a cone you can create a parabola or a hyperbola. Each has its own place independently, but some things function very similar to one another. But the graph you will get whether it be a parabola or a hyperbola, will always be relatively similar.

Biometric technology offers an alternative to the most used system currently in place in most operations: passwords or personal identification numbers (PIN). Instead of users inputting their password or PIN, users interact with a computer terminal that will scan their finger, face, voice, retina, etc. to identify them. Many of the next generation personal computer systems will have integrated biometric technology so that no external hardware is needed. In the mean time, users can buy small peripherals, like a mouse with integrated biometric technology or a small finger terminal for finger scans, to secure their personal computers.

Biometric technologies are getting better and finely tuned. The rate of false readings and errors has sharply fallen. However it still requires careful consideration and planning to implement a biometric identification system. They are most costly and complicated to implement as compared with other authentication systems. A proper evaluation of the system is important before purchasing any biometric system. A thorough risk analysis is necessary. In many cases biometrics may be overkill. Biometrics must be used if there is high level of risk involved. Customer acceptance is also important when logging on to company websites. Home users might not be ready to install biometrics on home computers for online banking.
