Track description

Face anti-spoofing is essential to prevent face recognition systems from a security breach. Much of the progresses have been made by the availability of face Anti-spoofing benchmark datasets in recent years. However, existing face Anti-spoofing benchmarks have limited number of subjects(≤170) and modalities (≤2), which hinder the further development of the academic community.

To facilitate future face Anti-spoofing research, we release a large-scale multi-modal dataset, namely Chalearn CASIA-SURF, which is the largest publicly available dataset for face Anti-spoofing in terms of both subjects and visual modalities. Specifically, it consists of 1, 000 subjects with 21, 000 videos and each sample has 3 modalities (i.e., RGB, Depth and IR).

Participants should submit a ZIP file containing only one text file named exactly as required below (do not add any folder in the ZIP). The ZIP file can be named randomly. Each line in the txt file contains four parts and each part is separated by a space. The first three parts are the relative paths of the three modes of each test sample, and the last part is the prediction score that the sample belongs to the real sample.

For Example(Evaluation requirements scores are retained at least 6 decimal places):
