Method of encryption of particular parts of a document for privileged users access

摘要

The method involves encoding information contained in a data part of an original document (1) with an algorithm (6) and a key (8) for obtaining encrypted information, where the key is encoded with cryptographic keys (15). A restricted document is created with information that is different from the former information, where the format of the latter information is identical to the format of the former information and encrypted information (10) in metadata (16). An independent claim is also included for a method for consulting encoded original document.
