One person can now be identified in a billion population with a single strand of hair, according to a new report published by US researchers in the journal PLOS.

The scientists found that protein biomarkers in human hair could help in solving complex crimes and other related forensic science.

Decades ago, scientists perfected the idea of using DNA and fingerprints to identify people in any given population – because the fingerprints and DNA of each individual is unique and different. There are over seven billion people on Earth, and each individual has his own unique fingerprints and DNA – making it easy to catch criminals and other offenders.

Not only are fingerprints and human DNA unique and helping in solving forensic and archaeological problems, the iris in the human eye has also been found to be very unique to every human being on Earth. To this extent, governments require the capturing of fingerprints and the scanning of the iris as a security measure to tell one individual scientifically apart from another.

Use of DNA, fingerprints, and iris scanning in modern technology

There is no gainsaying the fact that fingerprints are now required in personal identity cards, in security databases, and to be able to unlock several digital devices such as mobile phones and security doors. Scanning of the iris could also be used to unlock security doors and mobile technologies, while the human DNA could be applied by law enforcement officers and crime scene investigators as well as archaeologists to unravel several mysteries.

When will Nigeria come of age in the use of fingerprints, DNA, and iris scanning?

It is lamentable that Nigeria is still very backward in the use of fingerprinting, DNA, and iris scanning to solve today’s security and technological problems.

Top politicians are assassinated day by day; hundred robberies take place everywhere; rapes and child molestations occur every second; and inexplicable crimes such as kidnappings and are perpetrated at an alarming rate – but almost none of these is solved by law enforcement authorities in Nigeria. Why?

Because the country lacks the security expertise and digital proficiency to solve common crimes and explore modern technologies.

Can Nigeria afford to be backward technologically in things that bring peace and progress to other countries? Can Nigeria afford to have mounting unresolved crimes staring them in the face, and technological advances that could have promoted the wealth of the people left unexplored?

Law enforcement authorities would be better armed if they had the technological capabilities to solve decades-long crimes. The common man in the country would be better equipped to succeed in life if he had the wherewithal to make money via mobile applications that could be accessed through fingerprints.

And both the people and the government would be better served if they both had the technological assurances of security peace through modern exploitation of fingerprinting, DNA, and iris scanning among other newer technologies flooding the market.

The Nigerian government should rise to provide a conducive environment where the people could live in peace while being able to meet daily obligations that would make the country great.

We must develop our potentials in the areas of identifying a single criminal via a hair strand out of the over 180 million in Nigeria; using iris scanning to open security doors; using DNA to understand ancient fossils and our archaeological past; as well as applying fingerprints to unlock or enhance the security of every kind doors or mobile applications in the country.
