A Survey of Water Mark Technique

Abstract

Nowadays digital multimedia data exchange through internet is main idea which requires protection to enhance security. The 2D barcode with a digital watermark is a widely interest research in security. In this paper we propose different watermark technique used for data hiding by applying the QR Code technique. By using QR code we have propose DWT (Discrete-Wavelet-Transform), DFT (Discrete-Fourier-Transform), DCT (discrete cosinetransform), SVD (singular-value decomposition) methodology for watermarking technique.
