Biometrics and Individual Human Scent

Did you know that no two humans have the exact same scent and that dogs can smell the difference? It is true. In fact a dog can smell the finger print mark left on a glass and then tell the difference between the human that left it and one that didn't and you can have other people touch the glass too and it knows the difference between the ones that touched the glass and those that did not. Amazing.

Additionally, there are many ways this can be used as a biometric identifier. For instance for security purposes the same a finger print, DNA, blood sample or face recognition. Human scent is unique to the individual and trained dogs only mess up and cannot tell the difference with identical twins and even sometimes that can't fool them. There are many research papers on this notable anomaly and you thought every one smelled the same except for that lady with the weird perfume at the office.

Well the difference is human pheromones and chances are you have heard of that. Many perfume makers comment about this saying that certain pheromones can attract the opposite sex. Is it true? Some scientists believe so, in the animal kingdom it has been absolutely proven, insects too. Can we use these laws of nature and the chemistry of the human body to guard against International Terrorism? Apparently, so, question is why are we not using these truths of science to our advantage?

There are many biometric markers we can use, and we should not rule any of them out. If the human scent is that distinct then it is a valuable source of information and we ought to take this into consideration, so please think on this.
