Recent Studies by Z. Jalil and Co-Authors Add New Data to Algorithms Findings.

"Authentication and copyright protection of information contents has always been a concern in print media. The problem has become more critical with the increasing use of the Internet and digital technologies," scientists in Islamabad, Pakistan report.

"Besides image, audio and video, the text is most extensively used medium travelling over the Internet. Digital libraries offer a quick and easy access to information such as e-books, archives, images, etc. However, making the protection of copyright is more complex and difficult. Increasing use of digital libraries, blogs and electronic commerce has made it necessary to protect digital contents. Digital watermarking came up as a solution for copyright protection problem. In this paper, we propose a novel text watermarking algorithm, which embeds the watermark image in the text (to be protected) logically using embedding algorithm and extract it later using the extraction algorithm. Experimental results demonstrate the effectiveness of the algorithm proposed in localized and dispersed attacks on the text," wrote Z. Jalil and colleagues.

The researchers concluded: "Evaluation methods like Normalized Hamming Distances (MID), Peak-Signal-to-Noise-Ratio (PSNR), Weighted Peak-Signal-to-Noise-Ratio (WPSNR), Mean Structural Similarity Index Measures (MSSIM) and Normalized Absolute Briar (NAE) metrics are used to measure the quality and similarity between original and extracted watermark images."

Jalil and colleagues published their study in International Journal of Innovative Computing Information and Control (A Novel Text Watermarking Algorithm Using Image Watermark. International Journal of Innovative Computing Information and Control, 2011;7(3):1255-1271).
