1 What is anonymization?

Anonymization is the process of removing or modifying any data that can identify an individual or a group, such as names, addresses, phone numbers, or email addresses. Anonymization aims to make data irreversibly anonymous, meaning that it cannot be linked back to the original source or matched with other data sets. Anonymization can be done by masking, replacing, deleting, or aggregating data elements.

2 What is de-identification?

De-identification is the process of reducing the risk of identifying an individual or a group from data, but not eliminating it completely. De-identification can be done by removing or modifying direct identifiers, such as names or social security numbers, and indirect identifiers, such as dates of birth or zip codes. De-identification can also involve adding noise, perturbation, or encryption to data elements. De-identification allows for some level of re-identification, meaning that data can be linked back to the original source or matched with other data sets under certain conditions or with additional information.

3 Why are they important?

Anonymization and de-identification are important for data privacy because they help to protect the confidentiality and integrity of data subjects, such as customers, employees, or patients. They also help to comply with data protection laws and regulations, such as the General Data Protection Regulation (GDPR) or the Health Insurance Portability and Accountability Act (HIPAA). By anonymizing or de-identifying data, you can reduce the risk of data breaches, identity theft, discrimination, or legal liability.

4 How to choose between them?

The choice between anonymization and de-identification depends on the purpose and context of your data use. Anonymization is more suitable for data that is intended for public release or sharing with third parties, as it provides a higher level of protection and does not require consent or authorization. De-identification is more suitable for data that is intended for internal use or limited sharing with trusted parties, as it provides a balance between protection and utility and may require consent or authorization. You should also consider the type and sensitivity of your data, the potential harm or benefit of re-identification, and the availability and cost of anonymization or de-identification techniques.

5 How to anonymize data?

When anonymizing data, you can use various techniques depending on the structure and format of the data. Generalization involves replacing specific values with broader categories, while K-anonymity involves grouping data records into sets with at least k records with the same values for certain attributes. Differential privacy adds random noise or distortion to data outputs, like queries or statistics, in order to prevent inference of individual values.

6 How to de-identify data?

Data de-identification requires various techniques, depending on the data format and structure. For instance, pseudonymization replaces direct identifiers with artificial or random values, such as codes or hashes. Additionally, L-diversity ensures that each group of data records with the same values for certain attributes has at least l distinct values for sensitive attributes, such as income or diagnosis. Encryption is another technique which transforms data into unreadable or scrambled form, using keys or algorithms.
