PROCÉDÉ MIS EN UVRE PAR ORDINATEUR, SYSTÈME ET PROGRAMMES INFORMATIQUES POUR LA GESTION ET LA PRÉSERVATION DES FICHIERS NUMÉRIQUES DANS LES LICENCES NUMÉRIQUES
A method, system, and computer programs for digital files management and preservation in digital licenses. The method comprises splitting a digital file into a plurality of tokens and distributing each token over computing nodes (101, 102, 103, 104) participating in a blockchain; splitting a first random key associated to the digital file into a plurality of portions and distributing each portion to each computing node (101, 102, 103, 104); shuffling, randomly, the computing nodes (101, 102, 103, 104) and its associated public keys; for each computing node (101, 102, 103, 104) encrypting the portion with the node's public key, and encrypting the received token and a hash function with a public key; storing a head token that corresponds to a first computing node of the blockchain and its associated public key in a digital license; and generating a multiencrypted key
