Inevitable Encounters: Backdoor Attacks Involving Lossy Compression

ArXi:2603.13864v1 Announce Type: cross Real-world backdoor attacks often require poisoned datasets to be d and transmitted before being used to compromise deep learning systems. However, in the era of big data, the inevitable use of lossy compression poses a fundamental challenge to invisible backdoor attacks. We find that triggers embedded in RGB images often become ineffective after the images are lossily compressed into binary bitstreams (e.g., JPEG files) for storage and transmission.
