• Starting off the decade in 1980, the NIST Speech Group was developed to research speech processing techniques. The Group still operates to this day.
  • In 1984, the U.S. Army started testing hand geometry for banking and financial transactions.
  • In 1985, a patent for hand geometry identification was secured by David Sidlauskas.
  • Another 1985 patent was awarded, this time to Joseph Rice for subcutaneous vascular pattern recognition. This technology uses the blood vessels just below the skin’s surface to recognize individuals.
  • Also in 1985, Ophthalmologists Aran Safir and Leonard Flom proposed that no two irises are alike.
  • In 1986, the National Institutes of Standards and Technology (NIST), together with the American National Standards Institute (ANSI), published a standard for the exchange of fingerprint minutiae data (ANSI/ NBS-I CST 1-1986). This was the first version of the standards used by law enforcement today.
  • In 1986, Drs. Leonard Flom and Aran Safir were awarded a patent for using the iris for identification. Dr. Flom approached Dr. John Daugman to develop an algorithm to automate human iris identification.
  • In 1988, the Lakewood division of the Los Angeles County’s Sheriff Department began using video images of suspects to search their digital mugshot database. Two researchers, Sirovich and Kirby, applied principle component analysis to facial recognition and proved that less than 100 values were needed to approximate an aligned, normalized facial image. This is known as the Eigenface technique which uses standard linear algebra.
