In 1686, Marcello Malpighi, an anatomy professor at the University of Bologna, noted fingerprint ridges, spirals and loops in his treatise.

Dutch anatomist Govard Bidloo’s 1685 book, “Anatomy of the Human Body” also described friction ridge skin details.

Nehemiah Grew published friction ridge skin observations in “Philosophical Transactions of the Royal Society of London” paper.

The 14th century Persian book “Jaamehol-Tawarikh” includes comments about the practice of identifying persons from their fingerprints.

In early Egyptian history, traders were identified by their physical descriptors to differentiate between trusted traders of known reputation and previous successful transactions, and those new to the market.

In a cave estimated to be at least 31,000 years old, the walls are adorned with paintings believed to be created by prehistoric men who lived there.

Other characteristics have also been used throughout the history of civilization as a more formal means of recognition. Individuals use these characteristics, somewhat unconsciously, to recognize known individuals on a day-to-day basis. The concept of human-to-human recognition is also seen in behavioral-predominant biometrics such as speaker and gait recognition. This simple task became increasingly more challenging as populations increased and as more convenient methods of travel introduced many new individuals into- once small communities. Since the beginning of civilization, humans have used faces to identify known (familiar) and unknown (unfamiliar) individuals. One of the oldest and most basic examples of a characteristic that is used for recognition by humans is the face.
