Abstract

Les réalisations de la présente invention divulguent un procédé de reconnaissance de caractères, un dispositif, un dispositif électronique et un support de stockage, lesquels sont liés au domaine technique du traitement d’images. Le procédé comprend l’acquisition une image de caractères correspondant à l’identifiant unique et à un résultat normalisé de l’image de caractères selon l’identifiant unique du client, l’extraction des caractéristiques de l’image de caractères et la génération d’un ensemble d’échantillons selon les caractéristiques de l’image de caractères et le résultat normalisé. L’ensemble d’échantillons est envoyé au client selon l’identifiant identification afin que le client reconnaisse l’image d’un caractère devant être reconnue par l’intermédiaire de l’ensemble d’échantillons. La proposition technique du mode de réalisation de l’invention peut permettre d’éviter le problème lié au faible taux d’identification causé par différents environnements de paiements ou différents clients.
