How to anonymise data?
Data Anonymisation: GDPR and Data Privacy
An effective technique to safeguard the privacy of your user’s personal data is to anonymise or de-identificate the data. The data is updated with a series of often random characters to render it no longer identifiable and as a result anonymised.
For example user names can be replaced by ‘XXXXX’ and telephone numbers can be updated to keep the area code but with the other digits being replaced with zeroes.
Data Anonymisation – safeguarding the privacy of user’s personal data.
Data anonymization can be applied at the outset, when storing data, or at any later stage whenever the usage of the data changes (e.g. testing software systems, data analysis & profiling, data sharing etc.) or when the data needs to be removed (e.g. data deletion request, data retention limit exceeded). Removing data from a software system is often non-trivial. This is where anonymising the data by updating it to render it anonymous can be used.
