Abstract: The method of securing data transfer comprises: a step of attempting to transmit a document from a document sender to at least one document recipient, by implementing at least one transmission attribute and for at least one step of attempted transmission, a step of evaluating the value of at least one transmission attribute and a step of making the evaluation of the value of the transmission attribute available to the sender. Preferably, in the course of the evaluating step, the evaluation is dependent on the anomalies of correspondence that are observed for each attempted transmission. Preferably, in the course of the evaluating step, the evaluation is, moreover, dependent on the elements provided by the recipient in the course of a step of registering with an electronic document transmission service.

Abstract: An information processing method that includes the steps of determining a primary document having at least one definition of at least one secondary document related to the primary document, and creating a secondary document, the content of which automatically depends on the content of the primary document. In some embodiments, the primary document is associated with a time interval, and outside the time interval, the partially automatic creation of a secondary document is not authorized. In some embodiments, the content of the primary document defines the rights for the creation of a secondary document, and the process of creating a secondary document includes the step of checking the rights defined for the secondary document by the content of the primary document, and if the rights are not granted, the partially automatic creation of a secondary document is not authorized.
