- W2769426903 abstract "In today’s world, Internet is becoming essential for every human. There are various issues and challenges in data security in Internet system like the authenticity of content or matter, data validation, etc. These factors play crucial role in problems like unauthorized use, modification, etc., of the intellectual properties. Watermarking can resolve the stealing problem of intellectual properties. This technique is used to hide data or identifying information within images, audio, video, and documents which cannot be easily extracted by an unauthorized person. This paper shows an OTSU-DWT (Discrete Wavelet Transform) Algorithm which considers security along with quality for watermarking. The experimental result shows that the peak signal-to-noise ratio (PSNR) value and normalized correlation (NC) value are different for different tagged image file format (TIFF) image files. It could be seen that the PSNR value of original image does not decrease even after embedding the watermark on the contrary, it increases indicating quality improvement. Further, the NC values between original watermark and extracted watermark image showed that there is degradation of quality in extracted watermark." @default.
