Personal Verification/Identification via Analysis of the Peripheral ECG Leads: Influence of the Personal Health Status on the Accuracy

Figure 7

Subject 124 from the training part of ILSA database. Considering the independent correlation coefficients , , and , this subject will be identified either as subjects 320 (Max() = 0.98, max(, , ) = 0.98), 528 (Max() = 0.979), 240 ( = 0.98) or as subject 255 (min(, , ) = 0.96). However, the combined correlation coefficients ( + )/2, ( + + )/3 both have maximal values of 0.96 when the ECG in of this person is compared to his own ECG in .
