Abstract
(EN)
In some embodiments, a method includes sending an authentication request to a client device to obtain a utilization code in response to a request from the client device to access data. The utilization code is uniquely associated with the client device. The method includes obtaining an authentication response including the utilization code from the client device and authenticating the client device if the utilization code matches a utilization identifier stored in a database. The method includes generating an encryption key using a seed based at least in part on the utilization code and encrypting the data with the encryption key to generate encrypted data and sending, when the utilization code matches the utilization identifier stored in the database, the encrypted data to the client device without requiring a user of the client device to login.

Dans certains modes de réalisation, un procédé comprend l'envoi d'une requête d'authentification à un dispositif client pour obtenir un code d'utilisation en réponse à une requête provenant du dispositif client pour accéder aux données. Le code d'utilisation est associé de manière unique au dispositif client. Le procédé consiste à obtenir une réponse d'authentification comprenant le code d'utilisation provenant du dispositif client et à authentifier le dispositif client si le code d'utilisation correspond à un identificateur d'utilisation mémorisé dans une base de données. Le procédé consiste à générer une clé de chiffrement à l'aide d'une valeur de départ sur la base, au moins en partie, du code d'utilisation et du chiffrement des données avec la clé de chiffrement pour générer des données chiffrées et à envoyer, lorsque le code d'utilisation correspond à l'identifiant d'utilisation mémorisé dans la base de données, les données chiffrées au dispositif client sans qu'un utilisateur du dispositif client soit obligé de se connecter.
