Generating Robust Adversarial Examples against Online Social Networks (OSNs)

1 code implementation19 Oct 2023 Jun Liu, Jiantao Zhou, Haiwei Wu, Weiwei Sun, Jinyu Tian

In this work, we aim to design a new framework for generating robust AEs that can survive the OSN transmission; namely, the AEs before and after the OSN transmission both possess strong attack capabilities.

Rethinking Image Forgery Detection via Contrastive Learning and Unsupervised Clustering

1 code implementation18 Aug 2023 Haiwei Wu, Yiming Chen, Jiantao Zhou

To resolve this dilemma, we propose the FOrensic ContrAstive cLustering (FOCAL) method, a novel, simple yet very effective paradigm based on contrastive learning and unsupervised clustering for the image forgery detection.

Park

The challenge is composed of two tracks with an emphasis on fidelity and complexity constraints: In Track 1, participants are asked to optimize objective fidelity scores while imposing a low-complexity constraint (i. e. solutions can not exceed a given number of operations).

Privacy Leakage of SIFT Features via Deep Generative Model based Image Reconstruction

1 code implementation2 Sep 2020 Haiwei Wu, Jiantao Zhou

It is shown that, if the adversary can only have access to the SIFT descriptors while not their coordinates, then the modest success of reconstructing the latent image can be achieved for highly-structured images (e. g., faces) and would fail in general settings.
