The notary must also ensure that the software and applications he uses are secure, for example that the data is encrypted when it is transferred, but also when it is stored on the servers.
And when the technological notarial deed is signed remotely?

The notary will take additional steps to meet his obligations and better protect you. Among other things, he will ask you to send him, before the meeting, by a secure means of exchanging documents, a color copy of both sides of your identity documents. He may take screenshots for his file during the videoconference and ask you to move your identity documents in front of the camera to verify security features, or to use an online identity validation device. To this end, he may ask you if you are alone in the room and to move the camera so that he can see it. Finally, multiple authentication methods will be used to sign the notarial deed.
