Abstract: A method of identifying a physical person aims to obtain an advanced electronic signature, a qualified electronic signature or digital identity through the authentication to an application, the activation of which requires a functioning audio-video system and an internet connection, and includes: a user accesses the application, executes the registration process by entering his/her details and start, via encrypted channel, the onscreen wizard, following the steps indicated through audio and/or video messages proposed randomly by the application; and the qualified operator, in charge of the recognition for the checks saves, in “image capture” mode, evidence of various types, viewing all evidence and making a comparison in relation to dedicated databases. If the operator is certain, he digitally subscribes the successful recognition statement and makes a call that automatically sends an OTP code on the mobile phone. The input of the value derived therefrom confirms the registration/application form request.
