As we anticipated in a previous blog post, on April 22, 2020, the European Data Protection Board (“EDPB”) issued new guidelines on the use of location data and contact tracing apps in the context of the present COVID-19 pandemic.

The EDPB’s new guidelines complement and build on similar guidance previously issued by the Board itself (see here, here and here), and by the European Commission (see our blog post here).

The EDPB’s close scrutiny over the use of mobile data and apps in the context of the ongoing public health crisis is unsurprising, as many EU Member States have launched—or are in the process of launching—contact tracing apps to fight the spread of the virus, and these initiatives are receiving great attention by data privacy authorities and the general public (see our blog post here).

  • using contact tracing apps, which aim to notify individuals who may have been in close proximity to someone who is infected or confirmed as a carrier of the virus, in order to break the contamination chain as early as possible.

The EDPB stresses that EU data protection rules have been designed to be flexible and, as such, do not stand in the way of an efficient response to the pandemic.  However, it notes that governments and private actors should be mindful of a number of considerations when they use data-driven solutions in response to the COVID-19 outbreak.

On November 4, 2019, the Spanish Supervisory Authority (“AEPD”), in collaboration with the European Data Protection Supervisor, published guidance on the use of hashing techniques for pseudonymization and anonymization purposes. In particular, the guidance analyses what factors increase the probability of re-identifying hashed messages.

The AEPD explains that the probability of re-identification increases if more
