Abstract
The use of retinal biometric identifiers as security
devices in shipboard applications was investigated with the
use of the DOT 7.5(new version) and DAISY 7. 5( old version)
scanners of the Eye-Dentify Co. of Beaverton, Oregon. Motion
testing was the primary purpose of the thesis. It was the
first occurance of dynamic testing on any type of retinal
pattern recognition device. A transverse motion(only)
simulator that could roll up to fourteen degrees and sustain
a cycle per minute(cpm) rate of 6.0 was constructed and
utilized. The nature of the experiment was to test the two
scanners to determine if there would be significant
differences in the characteristics of the two, and their
possible uses at sea. Important conclusions were: 1) The
best results occured on the DOT 7.5, although five Type II
'RECOGNITION' errors were noted; 2) As period of roll and
angle of roll were increased in cpm's and degrees
respectfully, results were poorer; 3) Identification
threshold settings were allowed to be set too low at +0. 60
by the CRT lock manager, and should be raised to
approximately +0. 70. That way, the probability of the
occurance of Type II errors (false
RECOGNITIONS/VERIFICATIONS) would be greatly decreased; 4)
Retinal scanners are generally, very reliable.
