Abstract
SE DESCRIBEN HUELLAS DACTILARES Y TECNICAS DE DETECCION DE LAS MISMAS QUE, CONTRARIAMENTE A LOS SISTEMAS TIPICOS DE HUELLAS DACTILARES QUE SE UTILIZAN PARA OCULTAR SEÑALES DE VIDEO, SON COMPATIBLES CON TODAS LAS FORMAS CONCEBIBLES DE SISTEMAS DE COMPRESION DE SEÑAL, AL MISMO TIEMPO QUE PERMITEN LA VISION DE LA SEÑAL DE VIDEO. LA TECNICA DE HUELLAS DACTILARES SE BASA EN EL PRINCIPIO DE APLICAR UNA DISTORSION ESPACIAL LOCAL MUY LIGERA A LOS PIXELS EN UNA IMAGEN DE VIDEO, Y SIMILARES, POR MEDIO DE UNAS CONFIGURACIONES DE TRAMA SELECCIONADAS. DE ESTE MODO, LA TECNICA PROPORCIONA MEDIOS PARA TRANSPORTAR, DENTRO DE LA SEÑAL DE VIDEO, INFORMACION SELECCIONADA EN FORMA DE HUELLAS DACTILARES QUE SE PUEDE DETECTAR ELECTRONICAMENTE, PERO QUE NO PUEDE VERLAS UN OBSERVADOR CRITICO QUE ESTE OBSERVANDO LA SEÑAL DE VIDEO. ES DECIR, LA SEÑAL DE VIDEO DE HUELLAS DACTILARES RESULTANTE APARECERA IDENTICA A LA SEÑAL DE VIDEO NO DISTORSIONADA. LA TECNICA DE DETECCION DE HUELLAS DACTILARES PERMITE LA RECUPERACIONDE LA INFORMACION TRANSMITIDA, QUE PUEDE COMPRENDER UNA INSTRUCCION PARA IMPEDIR QUE SE COPIE LA IMAGEN DE VIDEO DE LAS HUELLAS DACTILARES, MENSAJES QUE PERMITEN LA IDENTIFICACION DE LA FUENTE Y FECHA DE UNA COPIA NO AUTORIZADA DE LA IMAGEN DE VIDEO, ETC.
