Abstract
Images are the most common and convenient means of transmitting information as one image is worth than thousand words. The need for the protection of digital media has gained importance as the networked multimedia systems have rapid growth. Also images can now easily be copied and distributed due to improvements in imaging technologies and the ease with which digital content can be created and manipulated.This paper presents image watermark algorithms which are developed to ensure security and protection of images and pictures. The purpose of proposed digital watermarking is not only to restrict use of multimedia resources, but also to facilitate data authentication and copyright protection for secure image transmission through Single Carrier Frequency Division Multiple Access (SC-FDMA).Simulation of the proposed algorithms is done using Matlab software and a comparison between them is done. The proposed algorithms are tested against image attacks using Checkmark software and the experimental results approved that the proposed algorithms have good robustness and they are resistant against cropping, scaling and compression distortion.
