After finger print, facial recognition, retina and iris scan a new Biometric identification method might come up in the forefront very soon.
Researchers at Spain's Universidad Politecnica de Marid. in collaboration with tech firm llia Sistemas SL, are developing a system that can verify people by their scent signatures.
 Though odor of person might not be a strong recognition proof as compared with iris or finger prints, but they can well perform when compared with facial recognition, as facial recognition has high error rate.
 Recognition system that are used today made people reluctant to participate, but according to the research team "The development of scent sensors that could identify a person as they walk through a system stall could provide less invasive solution with a relatively high accuracy" Researchers suggest that this technology can be installed in airport, border check points or anyplace where photo identification is required.
