Biometric security

What I know about Biometric security

I don't know anything about biometric security but, I can imagine it has something to do with security.

-What you wonder or questions you have about the topic before researching (at least 2)

1. 1.I wonder what biometric means or does and why it its important.
2. 2.I also wonder what it is used for

-Links to where you found the most useful information (at least 2, NOT Wikipedia, although you can use it to help you)

1. This website I found very helpful because it explained what biometric security is
2. This website was extremely helpful because not only did it explain in depth it also gave me example of all the types of biometric security systems there are and what they are used for.

-Bullet list of things you learned about the topic (at least 5)

1. -"Security personnel look for biometric data that does not change over the course of your life; that is, they look for physical characteristics that stay constant and that are difficult to fake or change on purpose."http://www.technovelgy.com/ct/technology-article.asp?artnum=10 
2. -Biometric security systems look for things that don't change or that are difficult to change everybody changes overtime hair color, height,weight etc.
3. -It is used to measure physical characteristics of a person on an "automated" buisness.
4. I learned that there are many different types of biometric systems, here is what the website said abourt them 
5. "Face Recognition biometrics security - This is one of the most flexible methods as it can be done without the person being aware that they are being scanned.  This system analyzes specific features that everyone’s face has like the distance between the eyes, width of the nose, position of cheekbones, jaw line and chin to only name a few.
• Fingerprint Identification - Your fingerprints remain the same throughout your life and no two fingerprints are alike.  This may not work in industrial applications as this requires clean hands and some people may have injury to their prints that prevent proper identification.
• Hand Geometry biometrics security - This will work in harsh environments, does not require clean conditions and uses a small dataset.  It is not considered as intrusive and is often used in industrial environments.
• Retina Scan - There is just no known way to replicate a retina and, as far as is known, the pattern of the blood vessels at the back of the eye is totally unique and never changes.  The downside is that it takes about 15 seconds of careful concentration to do a good scan but this still remains a standard one in military and government installations.
• Iris Scan - This is also very difficult to duplicate and stays the same for your lifetime although it may be difficult for children or the infirm.

• Signature biometrics security - This type of security is easy to gather and is not physically intrusive.
• Voice Analysis - This method of security biometric can be accomplished without the person’s knowledge although it is easier to fake by using a tape recording but it cannot be done by trying to imitate another person’s voice." http://www.findbiometrics.com/biometrics-security
6. I thought it was interesting that there were many ethical concerns about biometric security because people found it intrusive and other reasons.

-A short summary of how this topic connects/relates to you or your life

Everyday to enter the shcool or to get off the buses we have our fingerprints scanned and that is a type of biometric security. Also at our parent's office we also have that security system, I use biometric security systems everyday without even realizing it!

-Questions you still have (at least 1)

What other methods or type of biometric security are still being invented?

Who would have access to our information?
