Title
(EN) RETRIEVING HIDDEN DIGITAL IDENTIFIER
(FR) RÉCUPÉRATION D'IDENTIFIANT NUMÉRIQUE CACHÉ
Abstract
(EN)
A method of providing access to securely held data is provided. A user interacts with the service provider to obtain access to a service by using a device to provide a digital identifier to the service provider, without the digital identifier being made known to the user. At a later date the user wishes to retrieve securely stored data relating to their use of the service. However, because the user does not know the digital identifier, they are unable to identify themself to the service provider using the digital identifier. The present disclosure provides a secure method for exchanging private identifiers, which allows the user to identify themself to the service provider in order to gain access to securely stored data relating to the user's previous use of the service. The user can do this using the device on which the digital identifier is stored, or another device.
(FR)
L'invention concerne un procédé de fourniture d'accès à des données maintenues en sécurité. Un utilisateur interagit avec le prestataire de services pour avoir accès à un service en utilisant un dispositif permettant de fournir un identifiant numérique au prestataire de services sans que l'identifiant numérique ne soit porté à la connaissance de l'utilisateur. Ultérieurement, l'utilisateur souhaite récupérer des données stockées en sécurité concernant son utilisation du service. Cependant, comme l'utilisateur ne connaît pas l'identifiant numérique, il ne peut pas s'identifier auprès du prestataire de services grâce à l'identifiant numérique. La présente invention concerne un procédé sécurisé d'échange d'identifiants privés, qui permet à l'utilisateur de s'identifier auprès du prestataire de services afin d'accéder à des données stockées de manière sécurisée concernant l'utilisation préalable du service par l'utilisateur. L'utilisateur peut y parvenir grâce au dispositif sur lequel est stocké l'identifiant numérique ou d'un autre dispositif.
