When it comes to biometric authorization systems, there are many to choose from – candidates include face recognition, fingerprint recognition, ear recognition, voice recognition, tongue recognition and body odour recognition etc etc. But none is 100% perfect, so there’s always a demand for improvement and innovation. In 2016, a team from the Department of Computer […]

Recognizing cattle from their nose prints
Although computer-assisted facial-recognition techniques for cow-indentification are making considerable progress (see previous), there are other ways of doing so – nose prints for example. Researchers Ary Noviyanto and Aniati Murni Arymurthy of the Faculty of Computer Science, Universitas Indonesia, Depok, Indonesia, outline the details in a comprehensve report for the journal Computers and Electronics in […]
Printing on rodents’ tails (new patent)
“Animals have been marked for identification purposes for hundreds, if not thousands, of years.” – explains a new US patent awarded to Somark Innovations, Inc. of San Diego, California. The firm’s invention (marketed under the name Labstamp ® ) relates to the marking, for ID purposes, of animals, where the animal might be, say, a […]
Biometrics via armpit odo(u)r assessment (w & w/o deodorant)
In these days of intensified focus on accurate biometrics, the question may be asked: ‘Is it possible to ID an individual by their armpit odour – even if they use deodorant?’ Researchers Chatchawal Wongchoosuk, Mario Lutz and Teerakiat Kerdcharoen from Mahidol University, Bangkok, have made preliminary progress in this field. Their paper ‘Detection and Classification […]
Computerised gender classification (part 2, shoes etc)
The previous article in this series drew attention to the possibilities offered by eyebrows in the field of automated computerised gender classification. But eyebrows are by no means the only choice available to classifiers. For a recent (2015) roundup of the options on offer, see the work of Yingxiao Wu, Yan Zhuang, Xi Long, and […]
Computerised gender classification (part 1: eyebrows)
Can you tell a person’s gender from just a glimpse of their eyebrows? Could a computerised system do the same? To find out, a project was undertaken by Yujie Dong (of the Holcombe Department of Electrical and Computer Engineering, Clemson University) and Damon L. Woodard (now at the Biometrics and Pattern Recognition Lab, University of […]
Tongue ID
[sometimes it seems as though] As soon a new biometric security technology is developed, someone will find a way to bypass it. (see, for example, Progress in Fake-Finger Thwarting Improbable Research, April 16th, 2010). Steps towards implementing so-called ‘liveness detection’ mechanisms, which detect inert fakes, have helped. But in an ideal world, biometricians would like […]
Towards a robust nipple detector
Increases in raw computing power and novel algorithmic techniques have enabled outstanding advances in image processing since 1999, when Drs. Forsyth and Fleck developed the first computerised system for Automatic Detection of Human Nudes. Now, researchers at the Institute for Infocomm Research, I²R (pronounced as i-squared-r), which is part of A*STAR, Singapore, have refined the […]
