Below, find out what it is and what it does. What is GDPR? The General Data Protection Regulation 2016/679 (aka GDPR ) governs and harmonises all European laws on the subject through 99 articles and 173 “recitals”. Each State of the Union must therefore implement it without margins of freedom. The Regulation was published in the Official Journal of the European Union on May 4, 2016 and entered into force on May 25, 2018. Since that date , compliance with the GDPR has thus become mandatory for all EU states. The regulation establishes that the data must be processed exclusively after the informed consent of the interested party, who must know how they are collected and used, as well as the possible risks associated with their processing. It is not only a question of the right to the protection of personal data , which has already been established by Directive 95/46 . Rather, it is a proprietary view of data where informative self-determination is the cardinal principle .
