Abstract:
The widespread practice of indiscriminate data scraping to fine-tune language models raises significant legal and ethical concerns, particularly regarding compliance with data protection laws such as the General Data Protection Regulation (GDPR). This practice often results in the unauthorized use of personal information, prompting growing debate within the academic and regulatory communities.
Recent works have introduced the concept of generating unlearnable datasets (adding imperceptible noise to the clean data), such that the underlying model converges during training but fails to generalize to the unseen test setting. Though somewhat effective, these approaches are predominantly designed for images and are limited by several practical constraints like requiring knowledge of the target model and instability of bi-level optimization. To this end, we introduce RegText, an information-theoretic framework to operationalize the right to data protection in practice. In particular, RegText is a model-agnostic data generation framework that leverages the frequency distribution of tokens within a given dataset to create a ranking system, allowing for the systematic injection of selected words back into the dataset. We demonstrate RegText's utility through rigorous theoretical and empirical analysis of small and large language models. Notably, RegText can restrict newer models like GPT-4o and Llama from learning on our generated data, resulting in a drop in their test accuracy compared to their zero-shot performance and paving the way for generating unlearnable text to protect public data.
