Ancient documents present a very precious cultural heritage, hence the need to preserve and protect it and fight against illegal copying and pirating in its numerical form. The watermarking presents a promising solution for the copyright protection of these documents. Considering the importance in the number of color images, we propose in this paper a watermarking approach of color images from ancient documents, which adapts to the characteristics and content of each image. It is also based on the principal component analysis, the wavelet packet decomposition, and the singular value decomposition. The recorded results have shown that our algorithm has a good invisibility and an excellent robustness against different attacks relative to ancient documents.

Invisible watermarking methods have been applied in frequency domains, trying to embed a small image inside a large original image. The original bitmap image will be converted into frequency domain to obtain the discrete cosine transform (DCT) matrices from its blocks. The bits of the logo image are embedded in random color components of the original image, as well as in random positions in each selected block. These positions are alternating current (AC) coefficients of the DCT matrix. The randomness is obtained from RC4 pseudorandom bit generator that determines in which color component this logo image bits will be embedded. The embedded bits have been hidden in random blocks in the image, which are chosen according to a (semi-random) function proposed in this work.

With the development of Internet technology and human computing, the computing environment has changed dramatically over the last three decades. Cloud computing emerges as a paradigm of Internet computing in which dynamical, scalable and often virtualized resources are provided as services. With virtualization technology, cloud computing offers diverse services (such as virtual computing, virtual storage, virtual bandwidth, etc.) for the public by means of multi-tenancy mode. Although users are enjoying the capabilities of super-computing and mass storage supplied by cloud computing, cloud security still remains as a hot spot problem, which is in essence the trust management between data owners and storage service providers. In this paper, we propose a data coloring method based on cloud watermarking to recognize and ensure mutual reputations. The experimental results show that the robustness of reverse cloud generator can guarantee users embedded social reputation identifications. Hence, our work provides a reference solution to the critical problem of cloud security.
