What Techniques are Commonly Used for Data Anonymization?
Several techniques are employed to anonymize data effectively. These include:
Data Masking: Replacing identifiable information with pseudonyms or random characters. Generalization: Reducing the specificity of data to make it less identifiable, for example, using age ranges instead of exact ages. Perturbation: Adding noise to the data to obscure individual identities while retaining overall data trends. K-anonymity: Ensuring that each record is indistinguishable from at least k-1 other records in the dataset. Differential Privacy: Introducing random noise to the data queries to protect individual data points while allowing statistical analysis.
