运营商大数据平台的敏感信息保护研究

doi:10.3969/j.issn.1000-0801.2014.11.021

Abstract

Abstract:

The scope of sensitive information of carriers' big-data platform was discussed. The methods to protect sensitive information were described. The key technologies and mainstream technical methods in the field of research were summarized. Based on the layered architecture of carries big-data platform, technical solutions for different sensitive information protection technology were designed.

Key words: sensitive information protection, carriers' big-data platform, anonymization, privacy

	大数据平台原有风险	敏感信息保护平台加固效果
数据采集层	信息源伪造	利用私钥对信息源加密完成数字签名，确保数据来源可靠
	信息传输泄密	利用加密技术对敏感信息的传输提供安全保障
数据存储处理层	高度敏感信息明文存储	利用数据失真技术对高度敏感信息进行脱敏处理，再做持久化存储
	使用未脱敏的数据进行数据分析挖掘	利用随机化等技术对敏感数据进行失真处理，在保证敏感数据保密性的同时，保持数据的统计特性和分析可用性
	挖掘结果产生新的敏感信息明文	利用数据失真技术对挖掘结果中新产生的敏感信息进行脱敏处理，再做持久化存储
数据服务层	不需泄露应用层发布的非法/违规/敏感信息	利用抑制的方式对此类敏感信息数据项进行限制发布，即不发布这类数据项
	需要泄露应用层进行模糊处理的敏感信息	利用泛化的方式对此类敏感信息进行限制发布，即发布匿名化处理后的数据项
数据应用层	用户对于敏感信息的增/删/改/查等操作	利用实时监控功能对用户数据访问中涉及敏感信息的风险进行识别和阻断
	日志分散不完整，不能进行有效的审计追踪	利用增强的日志分析功能，对异常的用户数据访问行为进行跟踪和追溯
	对于敏感信息泄露风险缺乏预判	利用日志进行分析建模，发现风险出现的规律前兆，对敏感信息泄露提前预警
