Title
(EN) METHOD AND SYSTEM FOR THE AUTHENTIC DETERMINATION OF THE IDENTITY OF AN ELECTRONIC DOCUMENT WITH ITSELF AT A LATER DATE OR WITH A COPY THEREOF
(FR) PROCÉDÉ ET SYSTÈME DE DÉTERMINATION AUTHENTIQUE DE L'IDENTITÉ D'UN DOCUMENT ÉLECTRONIQUE AVEC LUI-MÊME À UNE DATE ULTÉRIEURE OU AVEC UNE COPIE DE CELUI-CI
Abstract
(EN) Method and system for determination of authenticity of an electronic document by comparing the document in question with itself at a later date or with a copy thereof, which method comprises two phases wherein the first phase is the entry of the original document and the second phase is the verification of the identity between the document to be authenticated and the original one. The method requires a double levelled system comprising of a satellite system accessible by the user and a central core system. Only values which are derived from the document in a predetermined way are stored in the core system and the core system generates an individual first code which is associated with the document. During verification a transformed control value is generated in the same way as previously from the document and the associated code, then based on the first code following a transformation access is provided to the transformed control value stored in the core system. If the two control values are identical the identity of the two documents is authentic.
(FR) L'invention concerne un procédé et un système de détermination de l'authenticité d'un document électronique en comparant le document en question avec lui-même à une date ultérieure ou avec une copie de celui-ci, ledit procédé comportant deux phases, la première phase étant la saisie du document d'origine et la deuxième phase étant la vérification de l'identité entre le document à authentifier et celui d'origine. Le procédé nécessite un système à double niveau constitué d'un système satellite accessible à l'utilisateur et d'un système de noyau central. Seules des valeurs qui sont tirées du document d'une manière prédéterminée sont stockées dans le système de noyau, et le système de noyau génère un premier code individuel qui est associé au document. Pendant la vérification, une valeur de contrôle transformée est générée de la même manière que précédemment à partir du document et du code associé, puis, sur la base du premier code suite à une transformation, un accès est mis en place à la valeur de contrôle transformée stockée dans le système de noyau. Si les deux valeurs de contrôle sont identiques, l'identité des deux documents est authentique.
