Iris scanners are being used at airports security. Ethnicity and eye color also play a role, the darker your eyes are the harder it is to scan.]]> 2018-09-25 15:33:41 UTC https://padlet.com/micca_caudill/6tdi7xnbxrqh/wish/285599216 https://padlet.com/micca_caudill/6tdi7xnbxrqh/wish/285599297 How is it used?  
- it can be used in many different ways. 
-You can see it in your everyday life like using siri, car blue tooth, cortana, google voice or the new amazon echo.  
- The most popular way to use it is using your phone especially in banks and other financial firms that have a lot of identity theft. 
-People also buy devices that tye for you when it hears your voice instead of using keyboards
-Its also seen in popular movies, such as the incredibles, to open secret places.

It is used in solving crimes. It can also be used to enter buildings and computer systems. For $50 dollars you can purchase a thumb scanner for your PC that will allow you to access files and web sites. Fingerprints can also be used as a payment system instead ]]> 2018-09-25 15:34:18 UTC https://padlet.com/micca_caudill/6tdi7xnbxrqh/wish/285599729 https://padlet.com/micca_caudill/6tdi7xnbxrqh/wish/285599845 The chance that two people have the same DNA is 6 billion to 1. The only faults in DNA is identical twins. Identical twins come from the same egg so they share identical genetic profiles. The best way to counter this problem is to use retina scans.]]> 2018-09-25 15:34:28 UTC https://padlet.com/micca_caudill/6tdi7xnbxrqh/wish/285599845 https://padlet.com/micca_caudill/6tdi7xnbxrqh/wish/285599846 Someone's DNA can be obtained through a blood, saliva, hair, or skin sample. The length and protein sequence of several small sections of the DNA strand are analyzed and looked at to generate a "DNA Profile", which is compared against other DNA profiles. Forensic testing looks for similarities in the genetic markers between two biological samples.

Yes Facial Recognition can be beat, but studies show that disguises have less effect on the matches than sudden weight gains or losses. In some cases scanners have been beaten by people holding up pictures of authorized personnel to the camera.]]> 2018-09-25 15:34:31 UTC https://padlet.com/micca_caudill/6tdi7xnbxrqh/wish/285599874 https://padlet.com/micca_caudill/6tdi7xnbxrqh/wish/285599887 How accurate is it?
Retinal and Iris scans are considered the most accurate biometric but doesn't work in all cases. Retinal scans doesn't work on people who are blind or have cataracts. Ambient lighting and the angle of your head can affect the accuracy ]]> 2018-09-25 15:34:32 UTC https://padlet.com/micca_caudill/6tdi7xnbxrqh/wish/285599887 https://padlet.com/micca_caudill/6tdi7xnbxrqh/wish/285599917 Today DNA testing is used almost entirely by law enforcement or in paternity cases. Nearly every state collects DNA from people convicted of violent crimes. The FBI's DNA database has data from more than 2.1 million DNA samples. It takes hours to analyze a DNA sample.]]> 2018-09-25 15:34:36 UTC https://padlet.com/micca_caudill/6tdi7xnbxrqh/wish/285599917 https://padlet.com/micca_caudill/6tdi7xnbxrqh/wish/285600140 How accurate is it?
- Voice recognition is not as accurate as biometrics
- It is highly susceptible to background noise
- The device that the voice is being recorded on could sound different to another device
- This is why voice recognition is usually paired with another biometric technology]]> 2018-09-25 15:34:55 UTC https://padlet.com/micca_caudill/6tdi7xnbxrqh/wish/285600140 https://padlet.com/micca_caudill/6tdi7xnbxrqh/wish/285600345 Can It Be Beaten?
The Iris scan- If you wear colored contacts or use substances  to dilate your pupils it CAN reduce the accuracy. 
Some Irises have been fixed to where if you were to have dilated pupils or anything on your eye it would detect that and you would have to hold up a high-resolution photo of an authorized eye, with a whole cut out to reveal the actual eye and pupil.

There are multiple ways to beat fingerprint scans. The more scientific way which is to make fake fingerprints out of gel or the more direct way which would be to cut off the persons finger.

- This depends on the type of system created
- Some just ask for phrases which can be recorded and used by another person
- Other systems ask for a combination of the voice and a confidential piece of information]]> 2018-09-25 15:39:39 UTC https://padlet.com/micca_caudill/6tdi7xnbxrqh/wish/285604063 https://padlet.com/micca_caudill/6tdi7xnbxrqh/wish/285606136 The most potentially dangerous problem with DNA is if an "imposter" gains a piece of your DNA such as a hair and they get your DNA Profile before you]]> 2018-09-25 15:41:47 UTC https://padlet.com/micca_caudill/6tdi7xnbxrqh/wish/285606136 https://padlet.com/micca_caudill/6tdi7xnbxrqh/wish/285606180 where have i seen this before? - you might have seen this in "Tomorrow never dies."
