La présente invention concerne un procédé de mise en œuvre d'image vectorielle pour une sortie de code-barres bidimensionnel à haute résolution et, en particulier, comprend : une étape de demande d'émission de certificat dans laquelle un terminal utilisateur accède à un serveur web pour fournir un service d'émission de certificat, de manière à demander l'émission d'un certificat à émettre ; une étape de fourniture de fichier de certificat dans laquelle, si le terminal utilisateur demande l'émission du certificat, le serveur web communique avec un serveur WAS sur la base d'un réseau de telle sorte que le serveur WAS génère, sous la forme d'un certificat électronique ayant une forme prédéfinie, le certificat demandé par le terminal utilisateur, et fournit, au terminal utilisateur, un fichier de certificat dans lequel une image de code-barres pour la prévention de falsification est insérée dans le certificat électronique généré ; une étape d'extraction d'informations d'identification de code-barres dans laquelle, si le fichier de certificat est reçu par le terminal utilisateur, le terminal utilisateur extrait des informations d'identification de code-barres insérées dans le fichier de certificat à l'aide d'un moyen comprenant un navigateur web et/ou un programme d'application pour la lecture d'une image de code-barres ; une étape de traitement de données de sortie d'impression consistant à générer une image vectorielle sur la base des informations d'identification de code-barres extraites et à traiter l'image vectorielle en tant que données de sortie d'imprimante ; et une étape de sortie de certificat authentique consistant à fournir en sortie les données de sortie d'imprimante traitées en tant que certificat authentique par l'intermédiaire d'une imprimante connectée au terminal utilisateur.
