Facial Recognition
Well, it has been awhile since I have written about Facial Recognition, primarily because I have been busy writing about the advances being made in Iris Recognition and Fingerprint Recognition these last few weeks.
Well, now Facial Recognition is making its limelight in the news today. Apparently, researchers at the University of Miami College Of Engineering have made some breakthroughs which improves the speed, accuracy, and efficiency of Facial Recognition. But what makes this level of research much more interesting is that it also takes into account the ear, and there is Research and Development being done on Earlobe Recognition, by examining the unique structure of the ear (if this becomes a viable Biometric Technology, it would be an exclusive one, based on the hypothesis that everybody has a different ear structure).
Various 2 Dimensional and 3 Dimensional Models of the face and the ear can be utilized, and accuracy rate in the range of 95%-100% have been claimed. Here are some more details of the first type of test: “The systems the researchers have designed can use 3-D facial images, or combine 2-D images of the face with 3-D models of the ear, which they construct from a sequence of video frames, to identify people by unique facial features and ear shapes. In the first method, the researchers use 3-D facial images with over 95 percent recognition rate, in the lab setting. Conventional shape matching methods commonly used in 3-D face recognition are time consuming.” (SOURCE: http://www.sciencedaily.com/releases/2009/11/091110090858.htm).
It should be noted that with the above test, the most unique features which were found and extracted were with the chin, mouth, eye brows, as well as the nose.
The second type of test is known as “Multi-Modal Ear and Face Modeling and Recognition”. Under this testing, “ . . . a set of facial landmarks from frontal facial images and combines this data with a 3-D ear recognition component-- a much more difficult identification process given the technique's sensitivity to lighting conditions.” (SOURCE: http://www.sciencedaily.com/releases/2009/11/091110090858.htm).
Final Thoughts On Today’s Posting
It is through the combination of the above mentioned two types of tests in this Posting which yields the high accuracy and success rate, not just one Biometric alone. This finding underscores a theme I have been saying all along.
Yea, Biometrics are a great tool for enhancing Security, but it should not be relied upon solely. It has its fair share of flaws and problems, just like other pieces of technology and Security technology which is out there.
Biometrics works great if it is used in conjunction with other layers of Security in a place of business or organization, or if it I used in conjunction with another Biometric Technology, such as the research described in this Posting. In other words, I am not just talking from a specific standpoint of Biometrics, I am talking from a standpoint of a cardinal rule in Security: It should be ingrained into your Security Policy not to just have one type or layer of Security defense, you need to have multiple layers.
As a business owner, I also do get fascinated with the latest and greatest in terms of technology. But when evaluating Security for your place of business or organization, you literally have to put blinders on and see what works best for you. There is nothing wrong using old fashioned Security techniques either.
At times, these in my opinion, work far better than the latest and greatest. To have maximum levels of Security, you should try to implement a combination of the latest and greatest and the old fashioned of Security techniques and technologies.
Back to Biometrics, I find this type of research truly fascinating. From the Postings I have written on, Facial Recognition has been used with other types of Biometric Technologies, in particular Iris Recognition and Fingerprint Recognition.
There have been serious considerations given to Facial Recognition for its use in the National ID Card and e-Passport schemes. This is the first time I have seen Facial Recognition being used in conjunction with the ear.
If Earlobe Recognition does prove to be a viable Biometric Technology, this could be a very powerful Multimodal Biometric Solution. Especially, taking into consideration how close the ear and face are together. Multimodal Biometric Solutions today use physiological features which are much more distant from each other, such as the iris and the finger.
But, no matter how much or many advances are made in Facial Recognition, it has cross the key test first, which is public acceptance of it, which is manifested in the fact that when compared to the other Biometric Technologies available, it is plagued with problems of Privacy Rights.
