Abstract:
Our modular approach to data hiding is an innovative concept
in the data hiding research field. It enables the creation of modular digital
watermarking methods that have extendable features and are designed for
use in web applications. The methods consist of two types of modules – a
basic module and an application-specific module. The basic module mainly
provides features which are connected with the specific image format.
As JPEG is a preferred image format on the Internet, we have put a focus
on the achievement of a robust and error-free embedding and retrieval of
the embedded data in JPEG images. The application-specific modules are
adaptable to user requirements in the concrete web application.
The experimental results of the modular data watermarking are very promising.
They indicate excellent image quality, satisfactory size of the embedded data and
perfect robustness against JPEG transformations with prespecified compression ratios.
