Researchers have developed TrajShield, a new defense framework designed to protect text-to-video models from generating unsafe content. This system addresses vulnerabilities in existing prompt-level defenses by analyzing the temporal trajectory of a generated video, identifying risks that emerge over time rather than just at the surface level of the prompt. TrajShield works by simulating a prompt's implied trajectory, pinpointing the source of potential danger, and applying targeted rewrites to neutralize risks while preserving the original semantic meaning.
