A novel image protection scheme named "cocktail watermarking" improves over current spread-spectrum watermarking approaches. Two watermarks, which play complementary roles, are simultaneously embedded into an original image. The new watermarking scheme has the characteristic that, no matter what an attack is, at least one watermark typically survives well and can be detected. Results of extensive experiments indicate that our cocktail watermarking scheme is effective in resisting various attacks.

Watermarking nombrado esquema del coctel "de la protección de la imagen un" de la novela mejora acercamientos actuales excesivos del watermarking del separar-espectro. Dos filigranas, que desempeñan papeles complementarios, se encajan simultáneamente en una imagen original. El nuevo esquema del watermarking tiene la característica que, no importa qué es un ataque, por lo menos una filigrana sobrevive típicamente bien y puede ser detectada. Los resultados de experimentos extensos indican que nuestro esquema del watermarking del coctel es eficaz en resistir varios ataques.
