Abstract:
(EN) A coupon-minter is configured to perform operations including: generating a coupon comprising encrypted discount information, wherein the encrypted discount information is encrypted with a discount key; generating, for the coupon, a hashlock from a preimage; introducing the coupon to a blockchain in association with the hashlock, wherein the blockchain is configured to permit claiming of the generated coupon only upon receiving access to the preimage used to generate the hashlock. A store-manager configured to perform operations including: claiming, using the preimage, the coupon in the blockchain; encrypting the discount key with a clearing-house public key; updating the coupon with the encrypted discount key. A clearing-house-manager configured to perform operations comprising: detecting the store-manager's claiming of the coupon; decrypting the encrypted discount key with a clearing-house private key to re-generate the discount key; and decrypting the encrypted discount information with the preimage.
(FR) Un dispositif de production de coupon est conçu pour mettre en oeuvre les opérations suivantes : générer un coupon comprenant des informations chiffrées de rabais, les informations chiffrées de rabais étant chiffrées à l'aide d'une clé de rabais ; générer, pour le coupon, un hashlock à partir d'une pré-image ; introduire le coupon dans une chaîne de blocs en association avec le hashlock, la chaîne de blocs étant conçue pour permettre de faire valoir le coupon généré, seulement lors de la réception d'un accès à la pré-image utilisée pour générer le hashlock. Un gestionnaire de magasin est configuré pour mettre en oeuvre les opérations consistant à : faire valoir, au moyen de la pré-image, le coupon dans la chaîne de blocs ; chiffrer la clé de rabais à l'aide d'une clé publique de chambre de compensation ; mettre à jour le coupon comportant la clé de rabais chiffrée. Un gestionnaire de chambre de compensation est configuré pour mettre en oeuvre les opérations consistant à : détecter la remise du coupon par le gestionnaire de magasin ; déchiffrer la clé de rabais chiffrée avec une clé privée de chambre de compensation afin de régénérer la clé de rabais ; et déchiffrer les informations chiffrées de rabais avec la pré-image.
