Processing of personal data is only lawful if one of the legal bases set out in the General Data Protection Regulation is met. The organization must be able to communicate the purpose of the processing and the legal basis to the data subject and, where appropriate, to the supervisory authority.
The documentation shall include at least:
One of the legal grounds for lawful processing of personal data is the implementation of the data controller or a third party's legitimate interests. To determine when a legitimate interest is justified, a so-called balance test is done to weigh controller or a third party interest against the basic rights of the data subject.
When our processing based on a legitimate interest, we document the implementation of the balancing test and its results so that, if necessary, we can demonstrate that our operations comply with GDPR.
GDPR defines six main legal bases for the lawful processing of personal data. In addition, more strict requirements apply to processing of special groups of personal data. The legal basis must also be communicated to the data subjects in privacy communication. However, not all legal bases adapt to all situations and the application of certain legal bases imposes additional requirements on the controller.
The Data Protection Officer (or other responsible person) helps to develop the lawfulness of the processing by assessing the legal bases for the different purposes in cooperation with the units carrying out the processing and on the basis of data protection communications.
