Principle in Focus — Lawfulness
Lawfulness means that every processing activity needs a legal basis or a justification. Laws differ most in this point: some are built on consent, others offer several equal legal bases.
Valid consent is freely given, specific, informed and unambiguous — and it can be withdrawn at any time. Pre-ticked boxes and consent hidden in terms and conditions do not count.
Consent is the rule under the General Principle, and explicit consent is needed for sensitive data. Exceptions include performance of a contract, legal obligations and the vital interests of the data subject.
