Embedding Watermark in Wavelet Domain Using Chaotic Sequence
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2016, Vol 4, Issue 4
Abstract
With the fast development of internet, Usage of various types of digital data like text, image, audio, video have been increased across the entire globe. Digital Media has several benefits like quality is higher, copying is simpler and editing is easier. So one can easily obtain other’s data and pretend to be the owner of that data. In watermarking, some information is embedded into digital media to prove ownership or to provide copyright protection. This paper introduce a method for digital watermarking based on discrete wavelet transform (DWT) using chaotic sequence as a spreading signal. Chaotic sequences are generated through chaotic map, which is determined by initial condition and parameters. The underlying system uses wavelet transform to convert original cover image from spatial domain to frequency domain and employs chaotic sequence to spread the watermark over wavelet coefficient. A large number of uncorrelated, random-like, yet deterministic chaotic sequences can be exploited to add the original watermark image to original image .
