Watermarking technology in QR code with various attacks

Abstract

Devour preservation and substantiation is becoming increasingly important on day-to-day life. Digital watermarking is the best technique developed to solve this problem. This is built using a digital watermark_wavelet_turn invisible for a QR code from the image. Converted into the investment process, a binary image, Logo, watermark adequate water, then put them in sub-selected band. Experimental results show that in all cases, this resistance to attack, and as such, can serve the protection of copyright and a viable authentication tool.
