Watermarking emerged as versatile technique of hiding confidential or copy right protect information. The image embedded with watermark is often prone to several security vulnerabilities due to several attacks. It is desired to secure the information in the form of watermark by making it immune to these attacks. Several techniques are prevailing which use image transform techniques for efficient watermark de-noising and extraction. However, in the recent past the evolutionary computing techniques evolved as promising methods. In this paper, one such attempt of integrating the popular image transform techniques with PSO for developing efficient watermarking scheme. Embedding and extraction of the watermark are demonstrated and finally the efficiency of the technique is evaluated in terms of calculated PNSR. Gray scale image is used as WM image and a color image is considered for hosting the WM image. The technique utilises only one frame of the color image for hiding securely the WM image instead of conventional method of using all the three frames.

使用进化计算技术的安全鲁棒水印性能

水印技术是一种隐藏机密或版权保护信息的通用技术。嵌入了水印的图像通常由于多种攻击而容易受到多种安全漏洞的攻击。希望通过使其不受这些攻击的影响而以水印形式保护信息。目前流行几种技术,它们使用图像变换技术进行有效的水印去噪和提取。然而,在最近的过去,进化计算技术发展为有前途的方法。本文尝试将流行的图像变换技术与PSO集成在一起,以开发有效的水印方案。演示了水印的嵌入和提取,最后根据计算出的PNSR评估了该技术的效率。将灰度图像用作WM图像,并考虑使用彩色图像托管WM图像。该技术仅利用彩色图像的一帧来安全地隐藏WM图像,而不是使用所有三个帧的常规方法。
