Pseudonymize

To assign a pseudonym, or fictitious name, to a piece of data or identifying information in order to conceal the true identity of an individual or entity. This process helps protect privacy by replacing sensitive data with an artificial identifier, making it difficult or impossible to link information back to a specific person without access to a key or decryption method. Pseudonymization falls short of complete anonymization, as the possibility to re-identify an individual may still exist under certain conditions. It's a valuable tool used in data security and privacy practices.
