摘要
纸币的防伪是世界各国金融系统都面临的十分重要又棘手的问题,笔者在保留了纸币原有防伪功能的基础上,提出了一种将数字化的QR Code二维码与数字水印技术相结合的新型的数字化防伪技术。利用RSA加密算法对纸币代码进行加密,并生成二维码。最后利用DWT域水印算法嵌入和提取水印图像。仿真实验结果证明了该技术的有效性。
Anti-counterfeiting of bank note is a very important and difficult issue which the world＇s financial system is facing.Based on the existing security features,a new digital security technology which combined digital two-dimensional code of the QR Code with digital watermark technology was proposed.The author used RSA encryption algorithm to encrypt the code,and then generated two-dimensional code.Finally,DCT-domain watermarking was used to embed and extract watermark image.The simulation results demonstrate the effectiveness of the technology.
