Abstract

La innovación involucra el uso de un láser para someter a ablación una microestructura calculada o el empleo de una adaptación de fotolitografía sin máscara que usa un dispositivo de microespejo digital para servir como modulador de luz espacial para embeber una pantalla de difracción de cubierta, mantener información encriptada bajo superficies transparentes de sustratos de plástico o vidrio. Un método incluye las etapas de fragmentar la pantalla de difracción calculada en por lo menos primeras y segundas partes que son colocadas en sitios separados. En este método el patrón binario en cada una de las partes incluye información que representa una porción respectiva de la imagen original y necesita ser interrogado simultáneamente para proveer una salida visual significativa: cada parte en sí misma no es apta de generar ninguna información significativa. El método de fragmentación permite un tipo de clave pública-privada de plataforma de sistema seguro.
