BadHash: Invisible Backdoor Attacks against Deep Hashing with Clean Label. (arXiv:2207.00278v2 [cs.CV] UPDATED)

Due to its powerful feature learning capability and high efficiency, deep
hashing has achieved great success in large-scale image retrieval. Meanwhile,
extensive works have demonstrated that deep neural networks (DNNs) are
susceptible to adversarial examples, and exploring adversarial attack against
deep hashing has attracted many research efforts. Nevertheless, backdoor
attack, another famous threat to DNNs, has not been studied for deep hashing
yet. Although various backdoor attacks have been proposed in the field of image
classification, existing approaches failed to …
