Hiding correlation-based watermark templates using secret modulation
A possible solution to the difficult problem of geometrical distortion of watermarked images in a blind watermarking scenario is to use a template grid in the autocorrelation func...

Image Ownership Verification via Private Pattern and Watermarking Wavelet Filters
Abstract. In this paper, we propose a watermarking scheme for the image ownership verification in terms of a private key pattern and wavelet filters. The watermarking is mainly ach...

Multiplexed clustered-dot halftone watermarks using bi-directional phase modulation and detection
We present a method for embedding and detection of visual watermark patterns in printed images that use clustered-dot halftones in the printing process. The method allows two inde...
