Description
Summary:Reliable image transmission is requirement of many fields of security and privacy nowadays for example, digital watermarking, stenography, encryption etc. Many researchers also consider secure image transmission as a robustness feature of digital watermarking. In this paper, product codes are proposed for secure image transmission due to their structural compatibility with the images. For decoding, a Modified Iterative Decoding Algorithm is used that is a suboptimum low complexity decoder whose easy hardware and software implementation makes it attractive for online applications. Mainly the purpose of this coding scheme is to make the image robust against various kinds of noise attacks during wireless transmission as the product codes have a great capability of correcting random as well as burst errors. Simulation results show the significance of proposed scheme.
