Abstract
The method for water-marking digital books with parameters includes developing, for each parameter, a new typeface on the basis of a pre-existing typeface, by creating at least one new code/glyph pair. The method includes developing a new coded text on the basis of the pre-existing coded text by replacing, in the pre-existing coded text, at least one code or group of codes from the pre-existing typeface. The method further includes allowing display of a character or a combination of characters from the digital book by the code or the group of codes from the new typeface allowing display of the graphically identical character or combination of characters on any screen. The code/group of codes from the new typeface has/have at least the code from the new code/glyph pair. The method also includes providing the new coded text and the new typeface as a water-marked digital book.
