A temporal chrominance trigger for clean-label backdoor attack against anti-spoof rebroadcast detection. (arXiv:2206.01102v1 [cs.CV])

We propose a stealthy clean-label video backdoor attack against Deep Learning
(DL)-based models aiming at detecting a particular class of spoofing attacks,
namely video rebroadcast attacks. The injected backdoor does not affect
spoofing detection in normal conditions, but induces a misclassification in the
presence of a specific triggering signal. The proposed backdoor relies on a
temporal trigger altering the average chrominance of the video sequence. The
backdoor signal is designed by taking into account the peculiarities of the
Human Visual …
