Recently, there has been discussion regarding whether or not it is GDPR-compliant to transfer encrypted data on applications based outside of the EU. An example of this is Dropbox, as they have US-based servers, therefore if personal data is transferred through the Dropbox system, then technically it has been transferred outside of EU jurisdiction and is no longer GDPR compliant.
However, personal data sent in this format is usually encrypted and only the necessary individuals are given the encryption key to gain access to the data. So, in this instance, is the transference of the data compliant?
Although, the data may have been transferred outside of the EU the encryption key is not stored on the Cloud servers, therefore there is no identifiable information from the provider. However, there is always a possible risk that a data breach will occur if an unauthorised source obtains the key by force.
