MMPro: A Decoupled Perception-Thinking-Execution Framework for Secure GUI Agent

摘要

Advances in automatic graphical user interface (GUI) agents have brought significant privacy and security challenges, especially cloud-based solutions that may leak sensitive data and be vulnerable to man-in-the-middle attacks. To address these issues, we propose MMPro, a novel GUI agent framework that adopts a separated perception-thinking-execution architecture. The perception module and the execution module process inputs locally to generate outputs to ensure security, and the thinking module operates on abstract representations to ensure the effectiveness of the GUI agent.By modularizing each stage while introducing a hybrid description language (HDL), MMPro transforms screen images into abstract structured representations, minimizing the risk of sensitive information leakage. Experimental results on the OSWorld benchmark show that MMPro outperforms existing GUI agent methods while ensuring strong privacy protection and real-time interaction capabilities. This work presents a pioneering approach to developing efficient, privacy-conscious, and explainable automated GUI agents.
