MOBISIG: EER and aEER (intersession variability).

Method	Skilled forgeries		Random forgeries
	EER	aEER (std dev.)	EER	aEER (std dev.)
	Training: session 1; testing: session 2
DTW	27.15	7.34 (11.53)	1.68	0.01 (0.07)
Manh.	14.31	9.35 (11.28)	5.21	2.10 (4.01)
SVM	17.35	12.45 (12.84)	9.00	5.00 (8.57)
	Training: session 2; testing: session 3
DTW	24.69	9.05 (15.85)	1.78	0.33 (1.98)
Manh.	15.49	10.94 (12.27)	5.05	2.48 (4.33)
SVM	18.24	13.74 (13.66)	8.59	4.84 (6.52)

Note. Training samples: 15. We used type (ii) local features for DTW and 62 features (feat62) for the Manhattan anomaly detector and SVM.
