Abstract

Currently, the scientific community faces challenges in data collection to investigations, where concepts such as anonymization, pseudonymization and pseudoanonymization They are fundamental. These processes seek to protect the confidentiality, integrity and availability of the information of the study subjects, in this case, the patients. Anonymization is an irreversible process that completely eliminates any possibility of identify an individual in a data set, meaning that once it has been anonymized information, any associated ID cannot be restored. On the other hand, pseudonymization involves replacing direct identifying data with alternative identifiers or pseudonyms, which allows us to continue maintaining certain information related to the individual, but without directly revealing his or her identity. Regarding pseudonymization, It is characterized by the encryption or transformation of data in a way that makes it possible to reverse the process with some additional information, which adds a layer of protection, but does not guarantees absolute anonymity.
