Data plays a critical role in today’s economy. The EU is currently developing data spaces to create a data market where data can be exchanged, sold, and utilized for various objectives, including training algorithms in medicine and other industries. In this data-driven economy, safeguarding personal data is a crucial issue that must be tackled by all stakeholders. It is imperative for organizations participating in the data market to ensure compliance with privacy regulations. However, this can be a challenging task, requiring the ongoing collection of consent for data usage and continuous monitoring to ensure compliance. This highlights the need for a specialist solution to handle privacy protection effectively. The Swiss Data Custodian is an open-source framework developed by the Swiss Data Science Center, that provides the necessary tools to govern data access and processing and enables secure and compliant data usage through contractual agreements. With its ability to easily integrate into existing systems, the Custodian takes care of privacy protection, freeing businesses from the burden of monitoring data usage and compliance and allowing them to focus on building their business case.
