Anonimización

Process of removing personal identifiers from data sets.

How the laws define this

Both instruments agree that anonymization is the process of removing or modifying personal identifiers or personally identifiable information from data so that individuals cannot be identified prior to processing. However, they diverge on mandatory obligations, identification scope, and the targeted technology. The Buenos Aires Province Generative AI Guidelines establish anonymization as a mandatory step specifically for data sets before processing them through GenAI tools, focusing simply on preventing individual identification. In contrast, Resolución 4/2025 - Directrices de uso de Inteligencia Artificial Generativa en la Administración Pública de la Provincia de Buenos Aires extends its focus to preventing both direct and indirect identification, while framing the process as applying particularly before processing with AI systems rather than limiting it strictly to GenAI tools or explicitly labeling it as an absolute mandatory prerequisite. Organizations must consequently determine whether they face a strict mandate tailored to generative AI tools or a broader framework addressing indirect re-identification across AI systems.
