Abstract: nowadays, the information processing system plays crucial part in the internet. Online information security has become the top priority in all sectors. The use of 2D Barcode or QR code with a digital watermark usage is interesting research work in the field of security. The semi visible watermarking of QR code with color image can prevent information from being disclose that is encoded in the form of QR code image. This paper proposes embedding of QR code into color image using DiscreteWavelet-Transform (DWT) watermarking technique. This technique includes encoding and decoding operation in frequency domain. The text message is hidden in the QR-code image. The QR code image is hidden into the Discrete Wavelet Transform. This technique performed well and additional security given to the information. The DWT uses Haar Wavelet Transform method hierarchically decompose a QR Code as well as the color image into a series of successively lower frequency Approximation sub band and their associated detail sub bands.
