Abstract

Le problème à résoudre par la présente invention est de fournir un système de plateforme de gestion d'informations capable de fournir de manière commode, à divers services, une technologie de gestion d'informations utilisant une chaîne de blocs. La solution selon l'invention porte sur un système de plateforme de gestion d'informations (1) qui utilise une chaîne de blocs (30) et qui comprend : une pluralité de dispositifs serveurs de service (20) qui fournissent des services de gestion de données souhaités ; un dispositif serveur de plateforme (10) qui accepte, à partir des dispositifs serveurs de service, des informations d'enregistrement comprenant des valeurs de hachage de données, et effectue un enregistrement dans la chaîne de blocs, et se référant à celle-ci, concernant les informations d'enregistrement dans le but d'une authentification d'authenticité pour celles-ci ; et un réseau de communication (40) qui connecte les dispositifs serveurs de service et le dispositif serveur de plateforme. Le dispositif serveur de plateforme est muni : d'une unité d'acceptation d'informations qui accepte des informations d'enregistrement provenant de la pluralité de dispositifs serveurs de service par l'intermédiaire d'une API ; d'une unité d'émission de transaction qui, lors de l'acceptation des informations d'enregistrement, émet une transaction relative aux informations d'enregistrement ; d'une unité de traitement de contrat intelligent pour effectuer, sur la base de la transaction provenant de l'unité d'émission de transaction, l'enregistrement des informations d'enregistrement dans la chaîne de blocs ; d'une unité d'acceptation de référence qui fournit une API à la pluralité de dispositifs serveurs de service, et qui accepte au moins une valeur de hachage relative aux informations d'enregistrement par l'intermédiaire de l'API ; d'une unité de traitement de recherche pour rechercher si la transaction d'une valeur de hachage visée est enregistrée sur la chaîne de blocs ; et d'une unité de rapport de résultat qui rapporte le résultat de recherche aux dispositifs serveurs de service.
