Preparation of a new project – what to do with the data

This scenario will take you step-by-step through the process of preparing a new project and how dealing with data. 

Step 1 – Determine whether personal data will be processed  #

The first step is to establish whether the project involves the processing of personal data. 

  • No personal data are processed → Data protection legislation (e.g. the GDPR) does not apply.  
  • Anonymised data only are processed (i.e. individuals are no longer identifiable) → the GDPR does not apply.  
  • Personal data or pseudonymised data are processed → the GDPR applies and the following steps should be undertaken.  

Step 2 – Identify the type of data  #

Determine which category of data will be processed. 

Possible scenarios include: 

  • anonymous data;  
  • pseudonymised data;  
  • directly identifiable personal data.  

The level of identifiability determines both the applicable legal framework and the necessary technical and organisational safeguards. 

Step 3 – Define roles and responsibilities  #

Clearly identify the role of each organisation involved in the project, especially in case of data-sharing or data transfers. 

This includes determining whether an organisation acts as: 

  • Data Controller, determining the purposes and means of processing;  
  • Joint Controller, jointly determining purposes and means with another organisation;  
  • Data Processor, processing personal data on behalf of a controller.  

Depending on their respective roles, appropriate agreements may include: 

  • Controller–Controller Agreement;  
  • Joint Controller Agreement;  
  • Data Processing Agreement (Controller–Processor);  
  • Consortium Agreement (for collaborative research projects).   

Step 4 – Obtain ethical approval  #

Before processing begins, submit the project to the competent Research Ethics Committee (REC) or Institutional Review Board (IRB) where required. 

The ethics review should evaluate: 

  • scientific validity;  
  • ethical acceptability;  
  • proportionality;  
  • participant protection;  
  • use of biological samples;  
  • data protection arrangements;  
  • legal basis for processing.  

Step 5 – Determine the source of the data  #

Identify how the personal data will be obtained. 

Possible situations include: 

  • prospective collection directly from participants;  
  • secondary use of existing datasets;  
  • receipt of data from another institution.  

Step 6 – Assess compatibility for secondary use  #

Where previously collected data will be reused for a new research purpose, assess whether the proposed secondary use is compatible with the original purpose of collection. 

This assessment should consider: 

  • applicable legal provisions;  
  • participants’ expectations;  
  • original information provided;  
  • original consent, where consent constituted the legal basis;  
  • ethical approval.  

If compatibility cannot be demonstrated, additional measures may be necessary, including obtaining new consent where feasible or redesigning the project. 

Step 7 – Establish the legal basis for processing  #

Identify the appropriate legal basis under the GDPR. 

For special categories of data, such as health or genetic data, identify both: 

  • the legal basis under Article 6 GDPR, and  
  • the relevant condition under Article 9 GDPR.  

Where applicable, national legislation governing scientific research should also be considered. 

Step 8 – Prepare the required documentation  #

Before commencing the research, prepare the essential governance documentation, including: 

  • research protocol or study design;  
  • participant information sheet;  
  • informed consent documents (where applicable);  
  • Data Management Plan;  
  • records of processing activities;  
  • data access policies;  
  • security measures;  
  • retention policies.  

Step 9 – Conduct a Data Protection Impact Assessment (DPIA)  #

Where processing is likely to result in a high risk to individuals’ rights and freedoms, conduct a Data Protection Impact Assessment (DPIA). 

The DPIA should: 

  • describe the processing;  
  • assess necessity and proportionality;  
  • identify privacy risks;  
  • define mitigation measures;  
  • evaluate residual risks.  

If the residual risk remains high despite mitigation measures, consultation with the competent supervisory authority may be required before processing begins. 

Step 10 – Implement appropriate technical and organisational measures  #

Appropriate safeguards should be implemented to ensure data protection throughout the project. 

These may include: 

  • pseudonymisation or anonymisation;  
  • encryption;  
  • role-based access control;  
  • authentication procedures;   
  • secure storage;  
  • backup systems;  
  • cybersecurity measures, etc. 

Step 11 – Assess international data transfers  #

Where personal data are transferred across borders, determine whether the destination country provides an adequate level of protection. 

Different scenarios apply: 

  • Transfers within the European Economic Area (EEA) or to countries benefiting from an European Commission adequacy decision may proceed without additional transfer authorisation, provided appropriate contractual arrangements are in place.  
  • Transfers to countries without an adequacy decision require appropriate safeguards under Chapter V GDPR, such as:  
  • Standard Contractual Clauses (SCCs);  
  • Binding Corporate Rules (BCRs);  
  • approved Codes of Conduct;  
  • approved Certification Mechanisms;  
  • other safeguards recognised under the GDPR.  

Step 12 – Obtain final authorisation and begin processing  #

Once all ethical, legal, organisational, and technical requirements have been satisfied, and all necessary approvals have been obtained, the research project may start.  

Step 13 – Monitor compliance throughout the project  #

Data protection compliance is an ongoing obligation. Researchers and institutions should ensure continued compliance with the GDPR and applicable national legislation through: 

  • review security measures;  
  • update the DPIA where necessary;  
  • monitor compliance with ethical approvals;  
  • document significant changes to processing activities;  
  • report and manage personal data breaches where required;
