Sweat Analysis and Its Role in Identification

Rakesh K Gorea, Abhinav Gorea

Abstract

Some methods of identification are already established like finger prints and DNA profiling but these types of evidence may not be always present or the procedure is costly or time consuming. For identification purposes additional biometric modalities are always being researched and body odour is another such biometric modality which is being researched but still it is under the process of development. In addition to identification purposes body scent analysis may help in diagnosis of diseases, crime scene investigations, search of human bodies and deception at security check points. The sweat analysis is carried out by different methods but many of them do not have real time applications as they are very time consuming, bulky and require especially trained persons to handle. Keeping in view these limitations research is being carried out to produce an instrument which can remove these short comings and in this direction E nose has been developed but still it has a lot of limitations. Attempt is being made to develop a real time E nose which may be as accurate as the nose of the dog and such type of instrument will have a big commercial use and carries a lot of financial potential.
