Summary


After two years successfully hosting 1M Deepfake detection challenge at ACM Multimedia 2024, 2025 with more than 200+ teams participating in the challenge, this year our focus is more on the explainability part of the manipulated content, along with the detection performance.

Task 1: Deepfake Detection – Given an image sample, the task is to identify if the image is a deepfake or real.
Task 2: Deepfakes Explainability – Given an image sample, the task is to find out the explanation behind the model’s decision with respect to the manipulation. The assumption here is that from the perspective of spreading misinformation.
