The EU digital rulebook strikes a balance between transparency for affected users and actors’ claims of confidentiality. The most prominent ex post transparency mechanism is the data subject access right to personal data under the General Data Protection Regulation. Yet, such access rights can be restricted in order to protect the rights and freedoms of others, including trade secrets. While jurisprudence about the balancing between conflicting positions of rights is consistent about the right to access corporate documentation such as log files in practice this often leads to a protracted legal battle. This panel will revisit experiences with trade secret claims by providers of digital technologies, the responsibilities of regulators and the impact of the digital omnibus on transparency rights.
