  • Publication number: 20090204878
    Abstract: The marked digital file (10) comprises a plurality of portions, some of which (12) are marked with a mark (14) of a string of marks so as to form a string of marked portions (12). Concatenating the marks (14) of the string forms a message. Each mark (14) contains an identifier (I, I0 to I5, J0 to J2) of the mark (14) defined by a numerical value, this value varying from one mark (14) to another as a function of the order of the mark (14) in the marked string. The string of marked portions (12) includes sub-strings, each of at least two marked portions (12) such that all of the portions (12), of a given sub-string are marked by the same mark (14).
