可追溯实名防伪票据系统的设计与实现

摘要

The authenticity and traceability of the bills ensured by technology means is always an important research direc⁃tion of bills anti⁃counterfeiting. The current situation and development trend of the bills anti⁃counterfeiting technology at home and abroad are introduced. The identification to the bill’s user in the process of bill application is researched. A method of fusing the digital bills output and identification system with identity information is proposed. The functions of identity information read⁃ing,data conversion and encryption,anti⁃counterfeiting bill output,and universal detection and authentication are realized by synthetically using RFID,two⁃dimensional barcode,virtual driver,hand⁃held terminal,and other technologies. The purpose of certificating and identifying the bill itself and user real identity is achieved. The experimental results show this method has high feasibility of engineering realization,and can effectively improve the safety of bill application.%通过技术手段保证票据的真实性和可追溯性一直是票据防伪研究的重要方向。该文介绍国内外票据防伪技术的现状及发展趋势，着重研究票据应用过程中对票据使用者的认证问题，提出一种融合身份信息的数字票据输出与认证系统的结构方法，通过综合使用射频识别、二维条码、虚拟驱动和手持终端等技术，实现身份信息读取、数据转换加密、防伪票据输出、通用检测认证等功能，以达到认证、鉴别票据本身及其使用者真实身份的目的。实验验证表明，该方法的工程实现可行性较高，能有效提高票据使用的安全性。
