International. A group of researchers from the University of Notre Dame, in the United States, have been carrying out an important research that seeks to develop a system based on facial recognition called "Questionable observer detector", which aims to identify criminals who return to the scene of the crime.
The task force is headed by Kevin Bowyer, a professor of computer science and engineering at the university, who is also the precursor of the idea, after listening to a dissertation by military and national security experts on the need to detect the presence of well-known Middle Eastern explosives manufacturers.
Bowyer, with fellow researchers, Professor Patrick Flynn and PhD student Jeremiah Barr, are pursuing studies on biometric identification systems using photography, facial thermography, iris and gait recognition.
The new system uses video surveillance, and seeks to identify people who appear in multiple videos of the scene of a crime and collate, at the same time, their facial biometric data, so that if they reappear in the same surveillance system an alert would be issued.
The researchers, while aware that this technology can raise civil rights concerns, hope that the advantages of the technology will be seen as an effective tool for military personnel and law enforcement agencies.
