This article talks about how the eye can be used for identity verification. Because the iris has such an intricate structure, each person’s is slightly different. For this reason, it has become the second most widely supported biometric characteristic, after fingerprints. Now, NIST (the National Institute of Standards and Technology) is working internationally to change the recognition standards and advance the iris images. The present international standard defined three competing image formats and three compression methods. However, it has been shown that only two of the three formats have worked well, which were centering, and then cropping the iris, or centering, and then cropping and masking eyelids and eyelashes. Also, only two of the three compression methods were able to make the images small enough for transmission while retaining the quality, which were JPEG 2000 and PNG. The purpose of this is to be able to expand the use of irises for identification. Instead of just using this technology as locks, perhaps one day, this technology can be used to create an iris database that will help identify victims.

3- I liked the involvement of the eye used in verification ID
2- I liked the idea of expansion of the use of the iris as well as possibly an iris database.
1- I like that this method is useful because there is more than 1 way to use the iris as a verification method
2- This article could have said if this method had been widely applied to criminal cases yet.
1- the article could have talked specifically about the eye structures an what makes them all different.
1- I learned that the iris can be used as a verification ID method, I was unaware of this and it’s success.
I have heard of the iris of the eye as a form of identification for security but I found it very interesting that they can make an identification database. I also liked how they have the technology now to do this and although it isn’t very efficient they are advancing to improve on the eye identification method. Another thing was how she mentioned JPEG 2000 and PNT as a way to send the iris images for identification by computers.
Two things I would suggest would be to describe the parts of the eye that would be used for identification and although every eye is different how would they map the eye to correctly identify people. I would also suggest showing what types of companies or for what security reasons are iris’s used for today.
One aspect I liked was how she showed that NIST, The National Institute of Standards and Technology is improving their methods and standards for this new method which could become the second most widely used biometric characteristic.
1 I like how scientist are constantly coming up with new methods of ID people.
2 The there are already technological improvements that are being worked on for this already new idea.
3 I like the idea of iris database that has all of the information.
1 I would have liked to know how the eye is examined to see the different structures.
2 I would also like to have known what other uses could this form of ID could be used for, security etc.
1 I never knew that the Iris could be a form of ID and that no two people have the same structure.
Three Aspects
- I liked how iris recognition is the second most widely supported biometric characteristic next to fingerprints.
- I also was surprised by the order of magnitude expansion of the IREX industy over the past five years.
- I also liked how useful this method is, and how there ae multiple ways to use iris examination as a verification characteristic.
Two Suggestions
- The article could have explored examples of when this verification method would be used in criminal cases.
- The article should have had more detail when describing how exactly irish examination could be used as a verification method
One thing i learned
- I learned that, next to fingerprints, iris recognition is the second most widely supported biometric characterisic.
One aspect of the review that I believed was particularly well presented was how now we can use the iris for identification. This will open up an entire new range of securities. I also thought that the ability for the images of the irises to be sent through computers will make it much more efficient and easy to monitor. A third aspect that I liked was that while this is not perfected yet, scientists are working hard t this to make it work right.
This article should go more in depth about the image formats and compression methods for the iris identification. Another suggestion is to maybe talk about the current software that is used for iris identification and why that is not satisfactory or talk about what technology that we have now that will be replaced by the iris software.
What I like the most about this article was that this iris software can not only be used for security purposes but it can also be formatted into an iris database like the DNA database that is used in forensics. Due to the recent ability for people to replicate DNA, the iris may be the new defining factor in a crime that will result in the perpetrator.
This was an interesting article. I liked the description of how the iris is used in verifying Identification of a person. Also, I liked how the idea of a iris database was expressed. Lastly, I liked how iris identification can be calculated by computers, and no two people have the same iris.
I would suggest that a more descriptive idea of how the iris works and parts of the eye that help identification. Also, i would suggest to say if there are ways to make your iris undetectable.
I learned that the iris can be used at identification, i had not known that in the past, and it was interesting to see how the iris can be used as a form of security.
There were several things I enjoyed about this review. It was easy to read while giving interesting facts about eye identification. I am glad to hear that it is becoming yet another strong identification tool for scientists and criminologists, as well as the fact that scientist are constantly coming up with new methods to ID people. I would have liked to know what instruments are used to examine the different structures of the eye, as well as the different purposes of this technology such as possibly security. I thought it was very interesting to find that no two people have the same eye structures, could this be true of identical twins?
