Abstract :
Proposed binary watermarking algorithm based on wavelet transform and Scrambling Technology. The carrier image scrambling transformation and wavelet transform, the watermark embedded image Low-frequency coefficients, when embedded in the energy range of different settings according to different embedding strength, and the binary watermark image itself is based on the characteristics of the superior and inferior values of pixel values of pixels located Different set of adjustment factors. At last, different binary text images are chosen for emulation experiment.
