Abstract:
The present invention relates generally to digital watermarking holographic structures. One method recites: creating a computer model; executing a transform domain iterative method to convert the computer model into a holographic structure; combining a digital watermark with the holographic structure; and conveying the combined digital watermark and holographic structure to a surface. Other combinations are provided and claimed as well.
