UniMark: Artificial Intelligence Generated Content Identification Toolkit

TL;DR

UniMark is an open-source toolkit that provides a unified, multimodal framework for AI-generated content detection, supporting both hidden watermarks and visible markings to enhance trust and compliance.

Contribution

It introduces a modular unified engine for multimodal content governance and a dual-operation strategy supporting both watermarking and visible markings.

Findings

Developed a standardized evaluation framework with three benchmarks.

Supported multiple modalities: text, image, audio, video.

Bridged gaps between algorithms and engineering for content verification.

Abstract

The rapid proliferation of Artificial Intelligence Generated Content has precipitated a crisis of trust and urgent regulatory demands. However, existing identification tools suffer from fragmentation and a lack of support for visible compliance marking. To address these gaps, we introduce the \textbf{UniMark}, an open-source, unified framework for multimodal content governance. Our system features a modular unified engine that abstracts complexities across text, image, audio, and video modalities. Crucially, we propose a novel dual-operation strategy, natively supporting both \emph{Hidden Watermarking} for copyright protection and \emph{Visible Marking} for regulatory compliance. Furthermore, we establish a standardized evaluation framework with three specialized benchmarks (Image/Video/Audio-Bench) to ensure rigorous performance assessment. This toolkit bridges the gap between advanced algorithms and engineering implementation, fostering a more transparent and secure digital ecosystem.
