Michigan State University (MSU) researchers have been studying how to test and calibrate fingerprint scanners that are commonly used at police departments, airport immigration counters, banks, and amusement parks. However, the researchers say without a standard life-like three-dimensional (3D) model to test the scanners, there is no consistent and repeatable way to determine the accuracy of the scans and establish a better scanner.

The researchers tested the scanners by creating life-size 3D hand models complete with all five fingers using a high-resolution 3D printer that can produce the same ridges and valleys as a real finger.

"This is the first time a whole hand 3D target has been created to calibrate fingerprint scanners," says MSU professor Anil Jain.

The researchers plan to design and develop standard models and procedures for consistent and reliable evaluation of fingerprint readers.

"We are very pleased with this research and how it is showing the uncertainties in the process and what it can mean for the accuracy of the readers," says Nicholas Paulter with the Security Technologies Group at the U.S. National Institute of Standards and Technology, which is funding the project.
