The Impact of Force on Fingerprint Image Quality, Minutiae Count and Performance

The impact of force on acquiring a high quality fingerprint image has been systematically studied by researchers using single print optical scanners. A previous study examined force levels that ranged from 3N to 21N using a single print optical sensor. A second experiment used force levels ranging from 3N to 11N using a capacitive and optical single print sensor. Additional work has been conducted that looked at smaller increments of force also using an optical sensor. This paper contributes to the body of knowledge by using an alternative fingerprint sensor, an alternative force level and compares it to the auto-capture method.
