Abstract Recently, much interest is being taken in a method to protect the copyright of digital data and prevent illegal duplication of it. However, in the area of CAD/CAM and CG, there are no effective ways to protect the copyright of the 3D geometric models. As a first step to solve this problem, a new digital watermarking method for 3D polygonal models is introduced in this paper. Watermarking is one of the copyright protection methods where an invisible watermark is secretly embedded into the original data. The proposed watermarking method is based on the wavelet transform (WT) and multi-resolution representation (MRR) of the polygonal model. The watermark can be embedded in the large wavelet coefficient vectors at various resolution levels of the MRR. This makes the embedded watermark imperceptible and invariant to the affine transformation, and also makes the control of the geometric error caused by the watermarking reliable.

Advances in technologies facilitate the end users to carry out unauthorized manipulation and duplication of multimedia data with less effort. Because of these advancements, the two most commonly encountered problems are (1) copyright protection and (2) unauthorized manipulation of multimedia data. Thus a scheme is required to protect multimedia data from those two above said problems. Digital Watermarking is considered as one of the security mechanisms to protect copyrights of multimedia data. The literature review reveals that the calculation of scaling and embedding parameters are not completely automated. In order to automate the procedure of calculating scaling and embedding parameters the computational intelligence need to be incorporated in the watermarking algorithm. Moreover the quality of the watermarked images could also be preserved by combining computational intelligence concepts. Thus watermarking schemes utilizing computational intelligence concepts could be called as intelligence based watermarking schemes and it is presented in this chapter in detail.

Watermark Image

This paper proposes a copyright protection system for digital certificate image using blind watermarking technique by applying discrete wavelet transform algorithm (DWT). The proposed technique utilizes three interrelated watermarks namely, Red watermark (RW), Green-watermark (GW) and Blue-watermark (BW). Firstly, RGB cover and RGB watermark image are divided for three color space R,G,B. Then the R component is chosen for embedding (RW), the B component is selected for embedding the (BW) and the G component is selected for embedding the (GW), R,G and B of the cover image are converted into the transform domain using DWT, and is subsequently decomposed into three levels viz.  LH1, LL2 and LL3 sub-bands. RW, GW and BW are then embedded onto LL3. Experimental results show that the performance of the proposed technique is very encouraging with average PSNR of 44 db, and NCC value of more than 0.99 for extracted watermarks after performing several types of attacks.

Blind Image

In this paper, an algorithm for data embedding in images is proposed. The algorithm is based on using the Discrete Wavelet Transform domain to embed digital data into images. In order to increase the algorithm robustness and ensure the authentication of the data extracted, error detection/correction coding techniques are used to encode the embedded data. The proposed algorithm is blind, i.e., the embedded data are extracted and authenticated without any reference to the original image or data. Experimental results demonstrate the low perceptibility of distortions caused by the data embedding and the high algorithm robustness against several common image-processing operations.
