3d grey image segmentation has become a promising approach to facilitate practical applications with the help of advanceddeep learning models. Although a number of previous works have investigated the vulnerability of deep learning models to backdoor attack, there is no work to study the severe risk of backdoor attack on 3d grey image segmentation. To this end, we propose two backdoor attack methods on 3d grey image segmentation, including Full-control Backdoor Attack (FCBA) and Partial-control Backdoor Attack (PCBA), on 3d grey image segmentation by leveraging a frequency trigger injection function and a rotation-based label corruption function. Our proposed trigger injection function is applied to insert a 3d trigger pattern into the benign 31) greyimages in the frequency domain while ensuring the invisibility of the trigger pattern. And the proposed rotation-based label corruption function is employed to yield the crafted labels with the aim of decreasing the performance of segmentation. Finally, through comprehensive experiments on a real-worlddataset, we demonstrate the effectiveness of our proposed backdoor models, the frequency trigger injection function, and the rotation -based label corruption function.
