Minutiae and Fingerprints
A study by the National Institute of Standards and Technology has shown that computerized systems that match fingerprints using interoperable minutiae templates, or a mathematical representation of a fingerprint image, have been highly accurate as an alternative to the full fingerprint image. The National Institute of Standards and Technology conducted the study, called the Minutiae Interoperability Exchange Test or MINEX, to determine whether fingerprint system vendors could successfully use a recently approved standard for minutiae data. There hope was that this would work rather than needing images of actual prints as the medium for exchanging data between different fingerprint matching systems.

Matt that was a well written article and was very interesting. Although it went right to the point it was not that detailed. Overall it sounds like a procedure tat would greatly help the field, thanks for the information.
The review of the article was very intriguing. I found that the concept that computerized systems that match fingerprints using interoperable minutiae templates, or a mathematical representation of a fingerprint image, have been highly accurate as an alternative to the full fingerprint image very interesting, but very much logical and expected. Also, I did, quite honestly, enjoy the brevity of the review, and how it was simple and to the point. A final aspect that I particularly found well presented was that it was clearly presented that it was the Minutiae Interoperability Exchange Test (MINEX)was conducted by the National Institute of Standards and Technology, which allows for the reader to know who did what, right off the bat. Although I did enjoy the review's succint character (I usually keep my writing very much so), I do feel that it was somewhat too succinct, and in being so, left out vital information to understanding what exactly was going on. Also, I would like to know how the MINEX results fell and what that information means, and how it would affect forensic science. One aspect of this review that I felt was particularly impressive was that the actual image of the fingerprint was not needed to identify it. This would allow for an entirely new era of forensic fingerprint recognition.
I thought that matt did a good job with this review. Some aspects of the review that i found were particluarly well presented include a nice brief analysis that covered the main ideas of the article without going into too much detail, a good topic of choice that pertains to the field of forensic science, and a good explanation of what exactly the new method being considered is and how it works. Two things that may have helped the review in my opinion could have been better sentence structure and more detail on how this new method could help change forensic science for the better. Overall, i thought that the review was well written and learned about a new method of matching fingerprints that may soon come into use.
This article that explains the matching of fingerprints through the use of minutiae templates was very interesting. The review of this technique was very clear and concise with no unnecessary information, short but sweet. The mathematical representations are a great new way to identify fingerprints and match them instead of the original fingerprint testing. Many good points were made in this brief explanation but I believe what this article was lacking was more detail about the test and its results. Overall it was a good article that showed the significance of fingerprint testing.
It was a great article and i was interesting about the new technology for fingerprints.
The review of the article was very good. I liked how the review was concise and well written. I would like to know however what the minex results were and what that means. All together great job.
