基于HBase的指纹支付系统

A Fingerprint Payment System Based on HBase

电子商务的发展使得网上交易的安全性成为热点,以密码方式保障支付安全的传统方式存在遗忘、泄露等多种问题.为提高用户支付时的安全性,本文提出以指纹信息作为用户身份验证的依据.但是,指纹信息较密码所需空间更多,传统关系型数据库在存储空间和读写速率上已无法满足支付系统的要求.因此本文使用HBase 作为支付系统的数据中心,并结合多线程技术,预先分配区域,写缓存等策略将数据并行存储到HBase 中.实验结果表明,当数据量较大时,该系统较关系型数据库SQL Server 在存储与查询效率上都具有优势;与原生HBase 相比,其存储性能也有-定提高.

The development of e-commerce makes the security of online transactions become a hot problem. Traditionally, passwords used toensure payment security are easy to be forgotten or leaked. To improve the security during paying, this paper uses fingerprintinformation as the basis of user’s authentication. However, compared with the passwords security ensuring, the fingerprintinformation need more storage space so that the traditional relational databases are not able to meet the requirement of paymentsystem in terms of storage space and I/O speed. Therefore, this paper uses HBase as the data center of payment system, combinedwith multi-threading technology, pre-assigned region and write caching policy to store data in parallel. The experimental resultsshow that, when data amount is large, the system has advantages in both storage and query efficiency over the relational databaseSQL Server; and compared with the original HBase, the storage performance of the fingerprint payment system also has beenimproved.
