It is no longer a novelty that more and more electronic devices are being used, in general, and that production processes are becoming increasingly digital. We find that vast amounts of data are generated every day in the economy, as well as through people's personal and social activities.

Data is an important component of the European Union's digital transformation process. Artificial intelligence is based on "smart information", and its development depends on how this data is managed in Europe.

We want to capture the important aspects related to this topic, using the logical method, the comparative method, the sociological method. We will analyze, synthesize, compare the various legislative provisions, correlating them with technical explanations, so as to reveal the importance of artificial intelligence in contemporary society.

The reading of this paper can be useful both for students and for teachers, lawyers, magistrates and other legal professionals, but also for those who are not in the field, but want to document themselves on the topic.

The novelty of our study will consist in merging the technical and legal notions proposed by the European Union, in our own interpretation and in a personal vision, so that the topicality of this subject emerges.
