Gao, Yansong, Doan, Bao Gia, Zhang, Zhi et al.

Understand

This work provides the community with a timely comprehensive review of backdoor attacks and countermeasures on deep learning.

  • According to the attacker's capability and affected stage of the machine learning pipeline, the attack surfaces are recognized to be wide and then formalized into six categorizations: code poisoning, outsourcing, pretrained, data collection, collaborative learning and post-deployment.
  • Accordingly, attacks under each categorization are combed.
  • The countermeasures are categorized into four general classes: blind backdoor removal, offline backdoor inspection, online backdoor inspection, and post backdoor removal.
