Everything you wanted to know about encryption and GDPR but were afraid to ask
This UK ICO guidance will help you to understand the importance of encryption as an appropriate technical measure to protect the personal data you hold.
Whether you are a controller or a processor, encryption is a technique that you can use to protect personal data.
- outlines the concept of encryption in the context of the GDPR’s integrity and confidentiality principle, and particularly Article 32 on security processing.
- provides a summary of current forms of encryption and the considerations you should have when putting it in place, along with outlining the residual risks.
- provides a number of scenarios where personal data is processed, outlining how encryption can be used to safeguard such data in respect of each scenario, and detailing some of the risks that remain.
- includes several recommendations, namely that where you are storing or transmitting personal data, you should use encryption due to its widespread availability and relatively low cost of deployment.
For an introduction to the key themes and provisions of the GDPR, you should refer back to the Guide to the GDPR. You can navigate back to the Guide at any time using the link at the top of this page. Links to other relevant guidance and sources of further information are also provided throughout.
When downloading this guidance, the corresponding content from the Guide to the GDPR will also be included as a cover page so you will have all the relevant information on this topic.
These pages sit alongside the ICO Guide to the GDPR https://ico.org.uk/for-organisations/guide-to-data-protection/guide-to-the-general-data-protection-regulation-gdpr/ and provide more detailed guidance for UK organisations on encryption under the GDPR.
