Key Independent Watermark Detection
Many types of pseudo-random signals have been used to embed signatures as watermarks, with spread spectrum signal techniques used to recover the signature from the encrypted data....

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...

RAINBOW: A Robust And Invisible Non-Blind Watermark for Network Flows
Linking network flows is an important problem in intrusion detection as well as anonymity. Passive traffic analysis can link flows but requires long periods of observation to r...

Robust bandlimited watermarking with trellis coded modulation
Digital watermarking is equivalent to bandlimited, powerlimited digital communication. The power limit is due to the requirement of imperceptible watermarks, and has long been rec...

Kerckhoffs-Based Embedding Security Classes for WOA Data Hiding
Abstract-- It has recently been discovered that using pseudorandom sequences as carriers in spread-spectrum techniques for data-hiding is not at all a sufficient condition for ensu...
