Abstract :
By the gradual support & enhancement in usage of internet, several issues are faced with respect to security.A safe & secure technique is needed to transmit the data. Digital watermarking is the method that ensures hiding of information & security. Watermarking is the method that hides the content or either detects the information in a digitized multimedia. Main focus of this discussion is on the watermarking of digitized audio, video & documents that are watermarked on a routine. This methodology has gained attention, particularly for indulging unidentifiable marks like copyright information about an author. This process includes a signal in a media that downgrades the visual ability of media.In this document, a watermarking method based on DWT is presumed to secures the data of an image & enhance the quality also.
Keywords :
Digital watermarking, Spatial domain, Least Significant Bit (LSB), Frequency domain, Discrete Cosine Transform (DCT), Discrete Wavelet Transform (DWT), Discrete Fourier Transform (DFT).
