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.
