Data pseudonymization is the process of substituting identifiable data with a pseudonym or a code. Pseudonymization is a privacy-enhancing technique that helps protect sensitive data from unauthorized access. The pseudonymized data is then stored separately from the original data, ensuring that even if the pseudonymized data is compromised, the actual data remains secure.
As a result of pseudonymization, personal data is transformed so that it is difficult to associate it with a particular individual.
