Pseudonymisointitoimet

Pseudonymisointitoimet refer to the actions or procedures involved in pseudonymization, a data protection technique used to conceal the identity of individuals. Pseudonymization involves replacing personal identifiers such as names, addresses, and social security numbers with artificial identifiers or pseudonyms, without removing the data from the database.

The primary goal of pseudonymisointitoimet is to protect personal data without completely anonymizing it. By pseudonymizing data, organizations can still use the data for statistical or research purposes, while also maintaining a high level of data protection. This is particularly important in industries such as healthcare, finance, and social services, where data must be kept confidential.

Pseudonymisointitoimet typically involve using cryptography or hash functions to create pseudonyms that are opaque to unauthorized individuals. The pseudonyms are then stored separately from the original data, making it difficult to identify the individuals associated with the data.

Organizations that implement pseudonymisointitoimet must also develop and maintain a "key" or "linking piece" that connects the pseudonymized data to the original data. This key is often stored separately and is only accessible to authorized personnel.

Pseudonymisointitoimet have become increasingly important in the wake of data protection regulations such as the European Union's General Data Protection Regulation (GDPR). By providing an additional layer of protection, pseudonymisointitoimet help organizations meet their data protection obligations while still utilizing valuable data. The use of pseudonymisointitoimet can also help organizations mitigate risks and maintain public trust in their handling of personal data.
