一种具有数字签名的二维码技术

摘要

The hidden hazards in the 2-dimensional bar code will spread to the scanner and cause unnecessary losses when a user scans a 2-dimensional bar code with unknown origin because of the current 2-dimensional bar code without identity authentication technology. At the same time,the current 2-dimensional bar code technology has no resistance,so it can not determine the authenticity of the identity of the producer.For this,we put forward a kind of 2-dimensional bar code technology with digital signature,which uses RSA digital sig-nature principle to complete the identification of 2-dimensional bar code.Therefore,if there are problem during the scanning,it can also be held accountable in the digital signature of the 2-dimensional bar code technology.The experiments show that the proposed technology is not only feasible,but also can enable the scanners to scan the 2-dimensional bar code from the regular user,which in turn guarantee the safety of the 2-dimensional bar code technology.%由于当前的二维码技术无身份认证技术,因此当用户扫描来源不明的二维码时,隐藏在二维码中的各种危害就将被传播给扫描者而造成一些不必要的损失.同时,当前的二维码技术也无抗否定性,因此其无法确定制作者身份的真伪.鉴于此,提出了一种具有数字签名的二维码技术.该技术使用RSA数字签名原理以完成二维码制作者身份的识别.因此在具有数字签名的二维码技术中,即使在扫描过程中发生了问题,也可以追究责任者.经过实验验证可知,具有数字签名的二维码技术不但可行,且可以使扫描者扫描到正规用户制作的二维码,进而在一定程度上保证了二维码技术的安全性.
