Secure Watermarking Algorithm based on DNA Sequence Using DWT-SVD

PP: 1-6
Marghny H. Mohamed, Saad Z. Rida, Basma Ahmed A. Hafez,
Due to the continuous development of information technology and the widespread use of digital media, such as text, videos, and digital images, the digital watermark has become one of the most important methods to protect digital media from tampering. DNA sequence-based image has been used as a biometric watermark for copyright protection and authentication, where the DNA sequence is a unique biometric feature and difficult to copy or duplicate. We have been presented a watermarking algorithm that based on Discrete Wavelet Transformation (DWT) and Singular Value Decomposition (SVD), in order to achieve imperceptibility. The quality of the watermarked image has been measured using peak signal to noise ratio (PSNR), at different DNA sequence-based images. This algorithm can be used for authentication and data hiding purposes.
