L'agence nationale de certification électronique TUNTRUST met en place le dispositif de Cachet Electronique Visible TN CEV 2D-Doc pour la sécurisation des documents électroniques et papiers moyennant un code à barre à deux dimensions (2D-Doc) incorporant la signature électronique de l'émetteur. Cette solution permet de sceller les données clés contenues dans un document moyennant une signature électronique rendue visible à travers un QR Code (code à barre à deux dimensions). Ainsi, un condensat des données clés est calculé puis signé par le certificat cachet électronique TN CEV 2D-Doc de l'entité émettrice. Les données clés et le condensat signé sont incorporés dans le QR Code apposé au document en guise de Cachet Electronique Visible pour garantir l’intégrité et l’authenticité de vos documents. La vérification du Cachet Electronique Visible TN CEV 2D-Doc se fait moyennant l'application QR-Check disponible gratuitement. Cette application permet de lire le Cachet Electronique Visible apposé sur un document moyennant la caméra de l'appareil mobile. Les informations incluses dans le cachet sont alors extraites et doivent correspondre aux informations inscrites sur le document. L'application QR-Check vérifie également la validité de la signature électronique de l'émetteur du document pour s'assurer de l'intégrité des données incluses dans le Cachet Electronique Visible.
