二维条码加密算法的研究

The research of Two-dimension bar code encrypt

目前二维条码在各行各业中运用极其广泛,因此条码中隐藏信息的安全性至关重要,提出一种有效的二维条码加密技术来保证信息的安全隐藏。首先利用基于DES和RSA混合加密算法对二维条码中的原始信息进行加密,再将加密后生成的二维条码图像用离散分数傅里叶变换双随机相位编码技术进行二次加密,从而生成最终的二维条码。解密时先对二维条码图像进行解密,再进行条码的识读,最后对识读的信息进行解密即可得到原始信息。

At present Two-dimension bar code had been used in many fields, so the safety of information in bar code is important, this article brought up a effective Two-dimension bar code encryption technology to assure the safety of information in bar code. Firstly, combining DES and RSA encryption technology to encrypt the original information. Then using dispersed fractional Fourier double random phase encode technology to encrypt the Two-dimension barcode image, we get the final Twodimension barcode. When Decoding the Two-dimension barcode, firstly, decoding the Two-dimension barcode image, then decoding the information in Two-dimension barcode to get the original information, this article research the Two-dimension barcode encrypt technology to assure the safety of information in Two-dimension barcode.
