Abstract

La fréquence des transactions commerciales ou activités analogues sur des systèmes en réseau est en progression constante, telles que les transactions avec cartes de crédit, connexions à des systèmes informatiques bancaires, utilisation de distributeurs automatiques, etc. A cet effet, l'invention concerne un système d'algorithme de mot de passe utilisant régulièrement des éléments variables tels que l'heure, la date, le jour de la semaine, le mois, etc. qui changent continuellement, ainsi que d'autres types d'éléments, de sorte que le mot de passe change en fonction des éléments variables de temps et des autres éléments. De plus, par la mise en application d'éléments variables dynamiques liés à l'identité de l'utilisateur, l'invention permet d'éliminer l'utilisation abusive d'informations privées, telle l'identité, pouvant être interceptées par une personne sur Internet. Une personne qui intercepterait les données d'identité mais pas leur algorithme ne pourraient pas les utiliser, car le système d'ordinateur de serveur ne les accepte pas.
