Abstract (en)
[origin: WO2020077048A1] The invention is a method for securing a digital document. An initial version of the digital document contains a set of data. The method comprises:- generating a link value by applying a preset function to a subset of the set of data,- allocating the link value to a target data belonging to the set of data and storing an entry comprising the target data in a secure storage unit, the target data being reachable in the secure storage unit through the link value, the secure storage unit being configured to use access rules for authorizing or denying a request initiated by a user and aiming at accessing the target data comprised in said entry,- generating an updated version of the digital document by removing the target data from the initial version of the digital document.
