An anti-counterfeiting e-ticketing system based on QR code and digital watermarking technique is discussed in the paper.The proposed embedded watermarking algorithm adopts a self-adjusting chaos key approach that greatly increases the watermarking capacity and improves the anti-counterfeiting performance.
