    Abstract: There is described a method for 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 step of digitally processing a sample image of at least one region of interest (R. o. I.) of the surface of a candidate document to be authenticated, which region of interest encompasses at least part of the security features, the digital processing including performing a decomposition of the sample image by means of wavelet transform (WT) of the sample image. Such decomposition of the sample image is based on a wavelet packet transform (WPT) of the sample image, preferably a so-called two-dimensional shift invariant WPT (2D-SIWPT)

    Abstract: Un método para comprobar la autenticidad de documentos de seguridad, en particular billetes de banco, en donde documentos de seguridad auténticos comprenden características (41-49; 30; 10; 51, 52) de seguridad impresas, aplicadas o dispuestas de otra forma en los documentos de seguridad, las cuales características de seguridad comprenden características visuales distintivas intrínsecas a los procedimientos empleados para producir los documentos de seguridad, comprendiendo dicho método los pasos de: - procesar digitalmente una imagen de muestra de al menos una región de interés (R.o.I.) de la superficie de un documento candidato a ser autenticado, la cual región de interés abarca al menos parte de dichas características de seguridad, incluyendo dicho procesamiento digital realizar una descomposición de la imagen de muestra por medio de transformada de ondícula (WT) de la imagen de muestra y extraer características clasificadoras (σ2, C, ...) de la descomposición de la imagen de muestra, y - colegir una calificación de autenticidad del documento candidato basada en las características clasificadoras (σ2, C, ...) extraídas, caracterizado porque dicha descomposición de la imagen de muestra se basa en una transformada de paquetes de ondícula (WPT) incompleta de la imagen de muestra e incluye descomponer la imagen de muestra en un árbol de paquetes de ondículas que comprende al menos un nodo de aproximación (Ai,j) y nodos de detalle (cVi,j, cHi,j, cDi,j.), y buscar el nodo de detalle dentro del árbol de paquetes de ondículas que tenga el mayor contenido de información.

    Abstract: THERE IS DESCRIBED A METHOD FOR 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 STEP OF DIGITALLY PROCESSING A SAMPLE IMAGE OF AT LEAST ONE REGION OF INTEREST (R.O.I.) OF THE SURFACE OF A CANDIDATE DOCUMENT TO BE AUTHENTICATED, WHICH REGION OF INTEREST ENCOMPASSES AT LEAST PART OF THE SECURITY FEATURES, THE DIGITAL PROCESSING INCLUDING PERFORMING A DECOMPOSITION OF THE SAMPLE IMAGE BY MEANS OF WAVELET TRANSFORM (WT) OF THE SAMPLE IMAGE. SUCH DECOMPOSITION OF THE SAMPLE IMAGE IS BASED ON A WAVELET PACKET TRANSFORM (WPT) OF THE SAMPLE IMAGE, PREFERABLY A SO-CALLED TWO-DIMENSIONAL SHIFT INVARIANT WPT (2D-SIWPT)

    Abstract: Se describe un método para comprobar la autenticidad de los documentos de seguridad, particularmente billetes, en donde los documentos de seguridad auténticos comprenden los rasgos de seguridad (41-49; 30; 10; 51, 52) impresos, aplicados o proporcionados de otra manera en los documentos de seguridad, cuyos rasgos de seguridad comprenden rasgos visuales de características intrínsecas en los procesos utilizados para producir los documentos de seguridad. El método comprende la etapa del procesamiento digital de una imagen de muestra de por lo menos una región de interés (R.o.l.) de la superficie de un documento candidato a autentificarse, cuya región de interés comprende por lo menos parte de los rasgos de seguridad, procesamiento digital que incluye la realización de una descomposición de la imagen de muestra por medio de la transformada de ondículas (WT) de la muestra. Tal descomposición de la imagen de muestra se basa en una transformada del paquete de ondículas (WPT) de la imagen de muestra, preferiblemente un cambio invariante bidimensional WPT (2D-SIWPT) así llamado.
