The DPIA or data protection impact assessment, is an important part of GDPR compliance. Under what circumstances do you need a DPIA, and how do you implement it?
What is a DPIA?
Also known as a privacy impact assessment, a DPIA is a tool which enables organisations to identify the most effective way of complying with data protection obligations and protect customers’ data – according to the ICO, the UK regulator. It is also defined as a privacy related assessment of how privacy can be affected by certain actions.
When is it required?
The ICO says that a DPIA is required under these circumstances:
- when using new technologies
- when the processing is likely to result in a high risk to the rights and freedoms of individuals
- when might processing pose a high risk to the rights and freedoms of individuals?
The ICO then lists three details relating to these circumstances, namely when processing of data is:
- systematic and extensive
- large scale and related to criminal convictions or offences
- and large scale systematic monitoring of public areas.
What should a DPIA include?
- A description of data processing and an explanation of the purpose and the rationale behind this processing.
- The DPIA should include an assessment of how necessary the data processing is and also whether the processing is proportionate to the purpose.
- A risk consideration, detailing any risks to data subjects that the processing may entail.
- And an outline of what measures are in place to reduce risk, this must include security procedures and technology used and show compliance with requirements under GDPR.
Finally, a DPIA can apply to multiple projects – meaning it may not be necessary to start a new DPIA for every project providing the specific data privacy related issues are covered in the existing DPIA.
A DPIA does not guarantee GDPR compliance in the areas described here, but it is an important tool in the compliance journey.
