New technologies, in particular artificial intelligence (AI), and Machine Learning (ML) are essential today for profiling users, in order to cope with their expectations to communicate "anywhere, anytime, on any device, for every service, with everyone ". It is important however to put the user at the center of the data system. Therefore, we have developed a model allowing to design a user-centric digital clone for the smart identity, application independent, and leaving control of data to the user. This step will lead to the design of the Smart Interface. We present our work and a Proof of Concept (POC), that demonstrates the possibility of digitizing personal information, by delivering the active user profile at any time.
