... quantization toolkits can be abused to activate a backdoor. We demonstrate that a full-precision backdoored model which does not have any backdoor effect in the presence of a trigger—as the backdoor is dormant—can be activated by (i) TensorFlow- ... all trained float-32 backdoored models exhibit no backdoor effect even in the presence of trigger inputs . Particularly, four influential backdoor defenses are evaluated, and they fail to identify a backdoor in the float-32 models. When each of ... PyTorch Mobile framework's post-training quantization, the backdoor is activated in the quantized model, which shows ...
