Abstract: Aiming at the problem that images are prone to misuse and infringement of users’ rights, the paper proposes an image protection method based on a poisoning attack strategy. The method generates poisoned data by embedding perturbations in the image data, which significantly reduces the performance of the deep learning model using this as training data without affecting the visual quality of the original image. Using image recognition and feature extraction techniques, the dominant features of the target image category are obtained as the basis for model recognition and classification, which are added to the original dataset as perturbations, and the perturbations are constrained at both pixel and feature levels; experimental results on CIFAR-100 and ImageNet-100 show that the poisoned images generated by the poisoned attack strategy effectively reduce the classification accuracy of a variety of common deep learning models’ classification accuracy.
