Data Anonymization is the alteration of PHI that makes it impossible to link individuals with their data. [1]

Data Anonymization is defined as the process of either encrypting or removing personally identifiable information from data sets, so that the people whom the data describe remain anonymous. In the context of medical data, anonymized data refers to data from which the patient cannot be identified by the recipient of the information. The name, address, and full post code must be removed together with any other information which, in conjunction with other data held by or disclosed to the recipient, could identify the patient [2]
