Reuse of personal data for a new purpose
The basic rule of the DPA is that personal data may not be processed further in a manner incompatible with the purposes for which it has been obtained (cf. Article 9.1). Article 9.3 provides, however, that the further processing of personal data for historical, statistical or scientific purposes shall not be regarded as incompatible as long as the data controller has made the necessary arrangements to ensure that the further processing is carried out solely for these specific purposes.
This means that the reuse of files for scientific research that has already been created is permitted, even if the file was created for a different purpose (cf. SURF, The legal status of raw data: a guide for research practice 2009:43).
Reuse of sensitive personal data
Regarding the reuse of sensitive data or data that is subject to professional confidentiality, the main rule is anyhow that the reuse shall be based on consent or meet the conditions for exemption from consent (as listed under Exemption from consent).
Third country transfers
According to Article 76 of the DPA, personal data subject to processing shall only be transferred to a country outside the European Union in the case that those countries guarantee an adequate level of protection.
Personal data may, however, be provided if the data subjects has unambiguous given their consent to such transfer (ct. Article 77.1 (a). It is therefore advisable when collecting personal data for scientific purposes to immediately request consent for sharing the data with colleagues, including perhaps colleagues abroad (cf. SURF, The legal status of raw data: a guide for research practice 2009:45).
