Research and Design of Signature Technology Based on QR Code

基于QR(Quick Response)码自定义加密解密算法的电子签章技术,对明文进行加密后快速生成二维码完成对设计蓝图的审核签章,利用Android平台进行二维码的快速扫描并解密展示签章内容。根据选择不同的编码集,系统自动调整加密算法产生不同复杂程度的密文形成二维码签章,Android扫描二维码后调用相应的解密程序进行签章解密。实践证明,该加解密算法在实际项目运用性能优越,稳定便捷,二维码辨识度高,应用效果非常好,使得规划设计领域的电子签章审核越来越便携实用,并已在规划设计类企业中得到应用。

This paper describes the self-defined electronic signature technology based on QR code, which generates two-dimensional code quickly to realize the review and approval of blueprints after encrypting the plaintext. It scans the QR code rapidly and decrypts the code to show signature content by Android platform. According to selection of different code set, system generates cryptograph of different complexity to form two-dimensional code signature by automatically adjusting the encryption algorithm. Android scans two-dimensional code and then calls the corresponding decryption program to decrypt signature. After putting into implement, it proves that the encryption and decryption algorithms have superior performance, stability and convenient as well as high code recognition in actual project. The application effect is very good, and it makes the electronic signature in the field of audit planning and design more portable and practical. It has been applied in enterprises in the planning and design area.
