• In 1960, Woodrow W. Bledsoe developed the first semi-automatic face recognition system. It may come as no surprise that this was via contract with the U.S. Government. His system required that the administrator locate features on a photograph (eyes, ears, nose, mouth). It then calculated ratios between these points that could be used to compare to available reference data.
  • Also in 1960, a Swedish professor named Gunnar Fant created a model that explained the physiological components of acoustic speech based on the x-rays of people making phonic sounds. This model gave us a better understanding of the biological components of speech and became an integral part of speaker recognition.
  • 1965 introduced the first automated signature recognition system based on research by North American Aviation.
  • In 1969, the FBI began searching for a system that could automate its fingerprint identification process. The existing manual process required an inefficient number of man-hours. The National Institute of Standards and Technology (NIST) was contracted for this quest. They earmarked two crucial challenges to its solution:
    • Ability to scan fingerprint cards and identify minutiae
    • Then to compare a scanned fingerprint to lists of minutiae
