Data Protection Impact Assessments
Where data processing is high risk, rely on our data protection specialists to conduct a thorough impact assessment to keep your business compliant.
If you are processing data that is likely to result in a high risk to individuals you need to perform a data protection impact assessment (DPIA). We also recommend doing a DPIA ahead of any big project that involves processing personal data in any way.
Experts in data protection & privacy law
In addition to assisting with data protection impact assessments, our team can assist you across all areas of data protection & privacy law, including:
Effective impact assessments to reduce data processing risks
DPIAs are all about assessing risk. In particular you need to ask: could the way you process data cause harm – either to individuals or to society as a whole? We can guide you through the DPIA process. In particular if you identify a high risk of harm that requires notifying the Information Commissioner (the ICO) our data protection solicitors can liaise with the regulator on your behalf. Our data protection impact assessments cover:
GDPR training
To ensure relevant staff understand the importance of DPIAs and when one might be necessary.
Provision of data protection impact assessment guidelines
Documenting the risk
To individuals following consultation with your data protection officer and other staff.
Compiling the DPIA
Describing the nature and context of your processing and ensuring full GDPR compliance.
Considering modifications to your processing methods to mitigate identified risks.
Reporting your intended processing project to the ICO if a high level of risk is identified.
Providing advice, where necessary on whether a DPIA is required, usually where processing is likely to result in a high risk to individuals.
This might be where you intend to carry out systematic monitoring or profiling or you are considering the processing of children’s data.
Responding to any decision by the ICO, that prevents you from processing the data.
Benefits of data protection impact assessments under the GDPR
Increased awareness of data processing
DPIAs encourage employees to think about the implications of their data processing activities, and in particular the risk of harm to individuals their work may cause.
Builds trust and confidence in your business
You don’t have to publish a completed impact assessment. However releasing the documentation – for example on your website – is a clear signal that you take data security seriously and will increase consumer trust.
Reduces risk
The data protection impact assessment procedure is designed to reduce the risk of harm to individuals. But a properly considered DPIA can also provide your business with compliance and financial benefits by reducing the risk of serious data breaches and regulatory sanctions.
Data protection impact assessment checklist – the essential
Remember that an impact assessment is a compliance tool designed to identify and reduce the risks involved in a particular project you intend to carry out. A properly considered and completed DPIA demonstrates that you have taken the necessary steps to avoid harming individuals through your data processing. You should:
- Provide a description of the processing – what is it for?
- Ask relevant staff about their processing activities: can they suggest what risks might arise?
- Obtain advice from your data protection officer.
- Confirm that the processing is necessary and proportionate.
- Set out how you intend to comply with GDPR principles.
- Assess the likelihood of harm to individuals.
- Identify ways to remove or reduce risk.
- Keep a record of all decisions that informed the DPIA.
- Ensure that precautionary measures identified in the DPIA are implemented before processing occurs.
Who we help: Businesses carrying out high volume data processing
A data protection impact assessment form is only required when your data processing is likely to result in a high risk to the rights and freedoms of individuals. And it is only if you can’t mitigate the risks that you need to consult with the ICO prior to carrying out the processing. At Harper James Solicitors, we have the expertise to identify risk and advise on mitigation. We are familiar with how the regulator approaches high risk processing and can liaise with officials there when your DPIA identifies a high level of risk that can’t be reduced.
