On September 18, the National Institute for Transparency, Access to Information and Personal Data Protection (Instituto Nacional de Transparencia, Acceso a la Información y Protección de Datos Personales or "INAI") issued a Guide for Personal Data Owners (source document in Spanish). The Guide covers distinct topic areas and is divided into four volumes: (i) general concepts of personal data protection; (ii) data protection guiding principles; (iii) ARCO (access, rectification, cancellation, and opposition) rights; and (iv) personal data procedures before INAI.
The content of this article is intended to provide a general guide to the subject matter. Specialist advice should be sought about your specific circumstances.
