The field of biometric recognition - automated recognition of individuals based on their behavioural and biological characteristics - has now reached a level of maturity where viable practical applications are both possible and increasingly available. The biometrics field is characterised especially by its interdisciplinarity since, while focused primarily around a strong technological base, effective system design and implementation often requires a broad range of skills encompassing, for example, human factors, data security and database technologies, psychological and physiological awareness, and so on. Also, the technology focus itself embraces diversity, since the engineering of effective biometric systems requires integration of image analysis, pattern recognition, sensor technology, database engineering, security design and many other strands of understanding.
Iris Ageing Debate in IET Biometrics
From time to time issues arise within the research community which spark widespread debate and, sometimes, disagreement.
In the biometrics research community there is just such an issue which has been generating considerable debate in recent months: the question of “iris ageing”.
IET Biometrics has published, in the same issue (December 2015), two key papers in this area from authors who have rather different views on the topic. One of these contributions (written by Ortiz and Bowyer of the University of Notre Dame) is A critical examination of the IREX VI results. The second paper (written by Grother and Matey, two authors of the original NIST report) is IREX VI: mixed-effects longitudinal models for iris ageing.
