8 DoD-Provided Dataset #1

The results of Section 8 are based on searches of the sequestered dataset DoD-Provided Dataset #1. This dataset consists of 5 259 probes collected operationally by the United States Department of Defense. All probes searched were a single sample depicting a region from a distal phalanx. No EFS data was provided. Only Subject-level ground truth information was provided.

8.1 Failures

Table 8.1 shows the number of failures to create templates. Table 8.2 shows the number of failures to produce a candidate list.

8.2 CMC

8.2.1 Plots

The CMC plots in Figure 8.1 show the FNIR of dermalog+0006 when searching DoD-Provided Dataset #1 against enrollment database where a single mated identity for each search probe was present. Tabular versions of FNIR at select ranks can be viewed in Table 8.3.

8.2.2 FNIR at Select Rank

The values in Table 8.3 correspond to Figure 8.1.

8.3 DET

8.3.1 Plots

The DET plots in Figure 8.2 show the false positive and false negative identification rate tradeoffs of dermalog+0006 when searching DoD-Provided Dataset #1 against enrollment database where a single mated identity for each search probe was present. Tabular versions of FNIR at select FPIR can be viewed in Table 8.4. Annotated values indicate similarity scores from the Subject line, which are tabulated in Table 8.5.
