摘要
针对web环境下普遍存在的电子公文被伪造和恶意删改等问题,提出一种方便可行的基于全文特征抽取生成验证码的电子公文加密防伪算法与验证技术。实践证明,采用这种技术开发的电子公文防伪系统能检验各种电子公文的真伪。
Aiming at the problems of electronic documents falsification, bowdlerizing hostility and so on, this paper introduces an encrypting arithmetic and validating technology based on characteristic getting which creates valid code of the electronic document. From the practice ,it proves that certificate testing system of electronic document which applys this technology can validate all kinds of true or false electronic documents.
