Data Anonymization Techniques
Methods used to protect sensitive information in datasets by making it impossible to link the data to an individual.
Data anonymization techniques are methods used to protect sensitive information in datasets. These techniques make it impossible to link the data to an individual, thereby protecting their privacy. There are several data anonymization techniques, including data masking, data perturbation, and data suppression. Data masking involves replacing sensitive data with fictional data, while data perturbation involves adding noise to the data to make it more difficult to identify individuals. Data suppression involves removing sensitive data from the dataset altogether.
Examples
- Using data masking to replace sensitive customer information with fictional data
- Applying data perturbation to a dataset to make it more difficult to identify individuals
Common misconceptions
- Thinking that data anonymization makes data completely secure
- Believing that data anonymization is only necessary for sensitive information
Also known as: data-deidentification
