Abstract
The invention protects a content of a digital or physical document against forgery. It allows automatic detection of any modification in an arrangement of graphical symbols (e.g. a text) provided on a support (e.g. printed or displayed) with respect to an original arrangement by providing on the support reproducible verifiable data including a verification barcode, while eliminating redundancy between data inside the barcode and the graphical symbols, and resolving the problem of the size of the barcode when the size of the data for these graphical symbols is large.
