An Hologram Watermark Technique Based on Image Partly Embedding
|
Abstract:
A new Hologram Watermarks Technique Based on Image Partly Embedding is presented. The digital holographic watermark is embedded into an original image. As the tradition hologram watermark technique is easy to be picked up and be attacked, in order to enhance its security, some improvements were made to the tradition method. the watermark is embedded in part of the image. And the position of the watermark embedded, the size of the watermark, the pixel of edge of the digital holograph are used as security lock. The experimental results indicate that this method is safer.
