This paper presents a general overview of the problems regarding the regulation of artificial intelligence (AI) raised in the official published works of the European Union (EU) and interprets these problems from the perspective of the Hungarian experts as a case study. Even though a new regulation on AI has already been proposed at the EU level, the paper evaluates specific rules and principles regarding data protection since data is the lifeblood of AI systems and the protection of such data is a fundamental right enshrined in the EU legislation via the General Data Protection Regulation (GDPR). The result of the study shows that the application of the GDPR on AI systems in an efficient and uniform way might be at stake since different outputs were generated by the experts to the same legal questions deriving from a scenario presented.
