Data protection principles are general principles and practices applying to the processing of personal data. They are intended to guide processing.
According to the principles, personal data must be
1. processed lawfully, appropriately and transparently
2. collected and processed for specified, explicit and legitimate purposes
3. collected only to the extent necessary for the purpose of the processing
4. updated whenever necessary: inaccurate personal data must be erased or rectified without delay
5. stored in an identifiable form only for as long as necessary
6. processed confidentially and securely.
The data protection principles must be observed for the entire life cycle of processing, that is, from the collection of the data to its storage and erasure. The principles must be observed at all times and cannot be derogated from even with the data subject’s consent.
