Legal Basis
One of the seven major data processing principles of GDPR is to ensure that personal data is processed lawfully, fairly, and transparently. To comply this principle, Chapter 6 of the GDPR requires any organization processing personal data to have a valid legal basis for that personal data processing activity. Think of these as scenarios in which it would be lawful to process data. GDPR provides six legal bases for processing: consent, performance of a contract, legitimate interest, vital interest, legal requirement, and public interest.
