As shown in Fig 1 and Table 1, our dataset has two advantages: (1) It is the largest one in term of number of subjects and videos; (2) Our dataset has three modalities (i.e., RGB, Depth and IR).In the proposed dataset, each sample includes 1 live video clip, and 6 fake video clips under different attack ways (one at tack way per fake video clip).
