Abstract: There is described a method of detecting security features (41-49; 30; 10; 51, 52) printed, applied or otherwise provided on security documents, in particular banknotes, which security features (41-49; 30; 10; 51, 52) comprise characteristic visual features intrinsic to the processes used for producing the security documents. The method comprises the steps of digitally processing a sample image (c 0 ) of at least one region of interest (R.o.I.) of the surface of a candidate document, which region of interest (R.o.I.) is selected to include at least a portion of said security features (41-49; 30; 10; 51, 52), which digital processing includes performing one or more iterations (N) of a multiresolution analysis (MRA) of the sample image (c 0 ) to extract classifying features (Ã 2 , C, ...) which are characteristic of said security features (41-49; 30; 10; 51, 52).

Abstract: There is described a method of checking the authenticity of security documents, in particular banknotes, wherein authentic security documents comprise security features (41-49; 30; 10; 51, 52) printed, applied or otherwise provided on the security documents, which security features comprise characteristic visual features intrinsic to the processes used for producing the security documents. The method comprises the steps of digitally processing a sample image (c 0 ) of at least one region of interest (R.o.l.) of the surface of a candidate document to be authenticated, which digital processing includes performing one or more iterations (N) of a multiresolution analysis (MRA) of the sample image (c 0 ).
