Abstract: For controlling the broadcasting of a digital document, the method brings at least three actors into play. First actor is an originator user computer system wherein a file is generated for containing the digital document, digital conditioning attributes corresponding to at least one predetermined event that is liable to affect the data in future use and information that secures data integrity are associated with the data. Second actor is a future user computer system which causes an occurrence of the predetermined event. Third actor is a remote computer system arranged for detecting the event occurrence by storing digital conditioning attributes and information that secures data integrity without knowledge of the digital document.

Abstract: The method for protecting data includes: assigning in the IT system of an author user, digital conditioning attributes of the data, corresponding to at least one predetermined event that is liable to affect the data in future use, attributing in the IT system, information that secures data integrity, setting up in the IT system, an envelope file carrying data, digital conditioning attributes affected to the data and information that secures data integrity, storing in a remote IT system, digital conditioning attributes affected to the data and information that secures data integrity, for each predetermined event related to the data, storing in the remote IT system an identifier of the event and its date, and at each connection, storing predetermined events corresponding to data attributes, in the IT system of the author, so that the IT system keeps track, for each event regarding data, the identifier of the event, the identifier of the user at the origin of the event and its date.
