Abstract
(EN)
Provided is an electronic transaction system which provides fair transactions. The electronic transaction system comprises a plurality of management servers, terminals and a transaction server. The plurality of management servers provide an electronic bulletin board. The terminals write, to the electronic bulletin board, bid data which includes encrypted prices. The transaction server acquires the written bid data, decrypts the encrypted prices, and executes transactions with the continuous auction method using the decrypted prices.

L'invention concerne un système de transaction électronique qui fournit des transactions équitables. Le système de transaction électronique comprend une pluralité de serveurs de gestion, des terminaux et un serveur de transaction. La pluralité de serveurs de gestion fournissent un panneau d'affichage électronique. Les terminaux écrivent, sur le panneau d'affichage électronique, des données d'offre qui comprennent des prix chiffrés. Le serveur de transaction acquiert les données d'offre écrites, déchiffre les prix chiffrés et exécute des transactions avec le procédé de vente aux enchères continue à l'aide des prix déchiffrés.
