Improving the Security of Spatial Domain Based Digital Image Watermarking using Chaotic Map and Cellular Automation
The security of digital image watermarking is improved by scrambling the watermark using different chaotic maps or cellular automata in such a way that an unauthorized person can’t recover the watermark without the secret keys. In this proposed scheme three secret keys are used in which one key is used to make the watermark chaotic and other two keys are used for scrambling the cover image. In ...
متن کاملRobust image watermarking in the spatial domain
The rapid evolution of digital image manipulation and transmission techniques has created a pressing need for the protection of the intellectual property rights on images. A copyright protection method that is based on hiding an ‘invisible’ signal, known as digital watermark, in the image is presented in this paper. Watermark casting is performed in the spatial domain by slightly modifying the ...
متن کاملDual Domain Semi-fragile Watermarking for Image Authentication
Techniques to establish the authenticity and integrity of digital images are becoming increasingly essential for secure transacting. Ideally, the authentication algorithm should distinguish incidental integrity maintaining distortions such as lossy compression from malicious manipulations. This has motivated research into semi-fragile watermarking. A novel watermarking algorithm is proposed in ...
متن کاملDigital Watermarking Techniques in Spatial and Frequency Domain
Digital watermarking [1] is the act of hiding information in multimedia data, for the purposes of content protection or authentication. In ordinary digital watermarking, the secret information is embedded into the multimedia data (cover data) with minimum distortion of the cover data. Due to these watermarking techniques the watermark image is almost negligible visible. In this paper we will di...
متن کاملImage Watermarking In Spatial Domain Using Qim and Genetic Algorithm
1 M. Tech Student 2 M. Tech (Ph. D) 1,2 Department of Computer Engineering 1,2 Galgotias University, Greater Noida, India Abstract— Digital watermarking is one of the proposed solutions for copyright protection of multimedia data. A watermark is a form of image or text that is impressed onto paper, which provides evidence of its authenticity. A digital watermark is digital data embedded in some...
