Red Teaming for Generative AI, Report on a Copyright-Focused Exercise Completed in an Academic Medical Center (2506.22523v2)

Abstract: Background: Generative AI deployment in healthcare settings raises copyright compliance concerns. Dana-Farber Cancer Institute implemented GPT4DFCI, an internal generative AI tool utilizing OpenAI models, that is approved for enterprise use in research and operations. Given (i) the exceptionally broad adoption of the tool in our organization, (ii) our research mission, and (iii) the shared responsibility model required by Microsoft OpenAI products, we deemed rigorous copyright compliance testing necessary. Case Description: We conducted a structured red teaming exercise in Nov. 2024, with 42 participants from academic, industry, and government institutions. Four teams attempted to extract copyrighted content from GPT4DFCI across four domains: literary works, news articles, scientific publications, and access-restricted clinical notes. Teams successfully extracted verbatim book dedications and near-exact passages through indirect prompting strategies. News article extraction failed despite jailbreak attempts. Scientific article reproduction yielded only high-level summaries. Clinical note testing revealed appropriate privacy safeguards with data reformatting rather than reproduction. Discussion: The successful extraction of literary content indicates potential copyright material presence in training data, necessitating enhanced inference-time filtering. Differential success rates across content types suggest varying protective mechanisms. The event led to implementation of a copyright-specific meta-prompt in GPT4DFCI; this mitigation is in production since Jan. 2025. Conclusion: Systematic red teaming revealed specific vulnerabilities in generative AI copyright compliance, leading to concrete mitigation strategies. Academic medical institutions deploying generative AI must implement continuous testing protocols to ensure legal and ethical compliance.
