Anonymization can be achieved through several methods: 1. Removal of Identifiers: This involves stripping off any direct identifiers such as names, social security numbers, or medical record numbers. 2. Code Assignment: Assigning a unique code to each sample that can only be linked to the patient through a separate, secure key. 3. Data Masking: Altering certain aspects of the data to mask any identifying information while preserving the integrity of the data for research purposes.
