提出了一种基于CQR码(彩色快速响应码)结构的彩色二维条码的实现方法。虽然第一个版本的CQR Code(CQR Code-5)是5种颜色的二维条形码，但这个新版本(CQR Code-9)有9种颜色。在本文中，我们描述了这种新的CQR码的实现细节。这种新版本的CQR码可以存储多达2048个信息位，需要4576个冗余位。里德-所罗门纠错算法的纠错率为34.54%。实验测试是通过在1.3 cm×1.3 cm的区域内打印CQR码来进行的。结果表明，CQR码-9适合于需要在较小的印刷区域中存储大量比特的密码应用。
This paper presents an implementation of a colored 2D-barcode which is based on the structure of the CQR Code (Colored Quick Response Code). While the first version of the CQR Code (CQR Code-5) is a 2-D barcode of 5 colors, this new version (CQR Code-9) has 9 colors. In this paper we describe the implementation details of this new CQR Code. This new version of the CQR Code can store up to 2,048 information bits, requiring 4,576 redundancy bits. The Reed-Solomon error correction algorithm provides an error correction rate of 34.54%. Experimental tests were performed by printing CQR Codes in a 1.3 cm × 1.3 cm area. Results show that the CQR Code-9 is suitable for cryptographic applications that require that a high number of bits be stored in a small printed area.
