Abstract

This report discusses a simple test method for image-based biometric verification systems. A fingerprint based computer login system is used as an example of the process used in this test method. Ideally, these tests should be performed on standard reference data such as NIST special database 24 but it is still possible to test blackbox versions of systems where it is not possible to enter previously stored image data into the system. The procedure presented here allows such a system to be tested using manual input of the data and manual recording of results when no software interface to the system is provided. This test procedure also allows the effect of image quality of the input sensor to be evaluation in the typical working environment where the system is to be used. For the system tested here, the quality of the input image was found to be both important and highly user dependent. The trade-off between false positives and rejection of valid users was approximately as expected and as specified by the system manufacturer.
