If the data processing is intended to serve the interests of the data subject, it may certainly be based on the balancing of interests clause of Art. 6 I f GDPR without further ado. In these cases, the rights or interests of the data subject are unlikely to be opposed or even outweighed - as required by Art. 6 I f of the GDPR. Data processing in the interest of the data subject is, however, not separately regulated by the GDPR.

An exception to this is data processing for the protection of a particularly weighty Schutzgut: life or vital interests. Under some provisions of the GDPR  processing that serves the vital interests of the data subject is explicitly privileged:

Articles: 6 I d, 9 II c, 18 II and 49 I f GDPR.

Recitals: 46 and 112 GDPR.

Example: Search for missing persons by the International Red Cross.
