【摘要】 针对保密性较高的工作数据或者其他原因导致的内外网物理隔离环境下数据交换困难的问题,通过对二维码生成和解析过程的研究,并且利用二维码可以携带数据、成本低和可随载体移动的特性,提出了使用二维码来解决一些特殊情况下的数据交换问题。由于单个二维码可携带数据有限,提出利用Protocol Buffer格式和LZMA压缩算法来简化和压缩需要通过二维码传输的数据,对于大型数据则采取多个二维码的组合方式传输。另外还简述了基于二维码的数据交换的应用前景。更多还原

【Abstract】 To solve the problem of high confidentiality work data or data exchange problems in internal and external network physical isolation environmen caused by other reasons,and through the research of QR code generation and the parsing process,We found that QR code has several characteristics,such as it can be used to carry data,low cost and it can follow the characteristics of mobile carrier.Then we raised the point of view that the QR code can be used to solve the problem of data exchange of some special cases.Because a single QR code can carry limited data,we put forward using the Protocol Buffer format and LZMA compression algorithm to simplify and compress the data that QR code transmits.And we used the combination of multiple QR code to solve the problem of large amounts of data.This paper also expounded the application prospect of data exchange based on QR code.更多还原
