1. A processing method performed by a system comprising a first processor unit in a first terminal, a second processor unit in a remote authentication server, and a third processor unit in a mobile telephone, to enable a user to access sensitive text data from a secure electronic document, the method comprising: a) the first processor unit obtaining the secure electronic document; b) the first processor unit triggering a display of the secure electronic document on the first terminal; c) the user selecting at least one marker that is contained in said secure electronic document and that is viewable by the user on a display of the first terminal, wherein: each marker of the at least one marker comprises a first identifier and a machine-readable code, and the at least one marker is selected by said third processor unit under user control when the at least one marker displayed on the first terminal is viewed by a camera device in the mobile telephone controlled by the third processor unit; c′) sending, by the third processor unit, the at least one selected marker to the second processor unit; d) on the basis of said at least one received marker, determining, by said second processor unit, secure data from which it is possible to recover at least one item of sensitive text data, wherein said secure data is recovered from outside said secure electronic document; f) the second processor unit determining said at least one item of sensitive text data for viewing from said secure data and transmitting determined data to the third processor unit, wherein the second processor unit transmitting the determined data to the third processor unit comprises: the first processor unit searching in a vicinity of the first terminal using wireless communication means; the first processor unit receiving a second identifier of the mobile telephone when it is in a detection field of the wireless communication means; and the first processor unit transmitting the second identifier to the remote authentication server, wherein the second processor unit identifies the mobile telephone to which the determined data is to be transmitted on the basis of the second identifier; g) the third processor unit obtaining said at least one item of sensitive text data; and h) the third processor unit triggering a display of said at least one item of sensitive text data.
