Robust Method for Hiding Binary Image into JPEG HDR Base Layer Image against Common Image Processing

Abstract

Hiding a binary image into color or grey images has been adopted as a useful watermarking method
for protecting ownership rights. We propose a practical method for this purpose. We generate a
particular binary pseudo-random sequence resembling the sequence used in code division multiple
access (CDMA) method. We scramble the input binary image normally representing the ownership
by using the modified Hadamard kernel, generate the CDMA binary sequence robust to image processing
distortions, and hide the resulting sequence in the normalized host image. Experimental
results show that our method guarantees the robustness against common image processing attacks
such as JPEG compression, cropping, scaling, histogram equalization, changing luminance and contrast,
etc.
