Whilst consent is a very useful legal basis for scientific research, it can present a challenge for researchers to meet the standards required by the General Data Protection Regulation (GDPR). Consent, as defined by the GDPR, is required to be a ‘freely given, specific, informed and unambiguous indication’ of the data subject’s wishes regarding the processing of their personal data. When consent is used as a legal basis to process special category data such as health or genetic data, consent is also required to be ‘explicit’.
For many studies, particularly those that are longitudinal or cohort-based, the collection of data began prior to the introduction of the GDPR and the consent form used may not have been designed to meet current requirements. Without a suitable legal basis for processing, it could be impossible to work with the data in the future.
The use of legacy consent may provide a way forward for researchers in certain circumstances. This approach requires the reassessment of the original, pre-GDPR consent to see if it is sufficient to permit new data processing. To help researchers perform an assessment, GHGA has developed the Legacy Consent Toolkit which can be used to guide someone making an assessment.
When performing an assessment there are 5 sections to be worked through:
The Legacy Consent Toolkit can generate a report based on this assessment with an indication of whether legacy consent might be a suitable legal basis for processing.
Development and publication
The GHGA Legacy Consent Toolkit was originally developed by Prof. Dr Fruzsina Molnár-Gábor and her team at Heidelberg University as part of GHGA. A publication regarding the use of legacy consent as a legal basis for processing for research was published in Zeitschrift für Datenschutz, 7/2022, 376-383.
This work has been further developed into an online app available in English. The App can be found at the bottom of this page.
We are continuing to improve and update the GHGA Legacy Consent Toolkit. If you have suggestions of how we can do so, or features you would like to see added, please get in touch.
