Abstract

本发明涉及一种防伪打印方法，包括：步骤1、在打印纸生产过程中，在纸张或纸卷中置入RFID电子标签，通过第一RFID读写器读取RFID电子标签的唯一硬件号；步骤2、云服务器将公钥下发给第一RFID读写器，第一RFID读写器结合公钥和唯一硬件号生成加密信息，并将加密信息写入RFID电子标签中；步骤3、打印机中内置有第二RFID读写器，在打印机开机或换纸时，通过第二RFID读写器读取RFID电子标签数据；步骤4、打印机将读取的RFID电子标签数据上传至云服务器，云服务器使用私钥对加密信息进行解密，并对解密后的结果进行验证，最终将验证结果回传给打印机。该方法能提高打印纸防伪造能力，且难以被破解。
