The permanent disassociation and removal of all personally identifiable information from a dataset, severing any possibility to trace or link the data back to the original contributor or individual. This anonymization process renders the data completely untraceable and anonymous, preventing any means of re-identifying the subjects, even by the organization that originally collected the information. It involves irreversibly stripping out or obfuscating all unique identifiers and reference details to ensure the anonymity of the data subjects cannot be reversed under any circumstances.
