Digital audio, video, images, and documents are flying through cyberspace to their
respective owners. Unfortunately, along the way, individuals may choose to intervene and …

A reversible watermarking algorithm with very high data-hiding capacity has been
developed for color images. The algorithm allows the watermarking process to be reversed …

Digital library research has attracted much attention in the most developed, and in a number
of developing, countries. While many digital library research projects are funded by …

This paper proposes a high capacity reversible image watermarking scheme based on
integer-to-integer wavelet transforms. The proposed scheme divides an input image into …

Recent developments in ICT, especially the web, have led to the creation of a growing
number of digital library projects in the UK, USA and elsewhere. This new phenomenon is …

The need for reversible or lossless watermarking methods has been highlighted in the
literature to associate subliminal management information with losslessly processed media …

Reversible data hiding enables host media to be restored from marked media without any
loss of host information. Since this reversibility helps to make right decision during image …

Investigators within the law enforcement and cyber forensics communities are generally
aware of the concept of steganography, but their levels of expertise vary dramatically …

Invisible watermarks are not all alike. Different techniques are used to embed different types
of watermarks into digital media objects to accomplish different goals. Some watermarks are …
