差分隐私（Differential Privacy）
差分隐私技术是最近研究比较多的一种保护方法，其思想是在数据的采集或发布前，对数据进行扰动（Perturbation）添加噪声，从而可以隐藏真实数据，避免具有背景知识的攻击者通过猜测，获取隐私信息。差分隐私保护技术给出了数据隐私保护程度及数据可用性之间的严格数学定义模型：

差分进化算法 (Differential Evolution)概述
DE算法简介 Differential Evolution（DE）是由Storn等人于1995年提出的，和其它演化算法一样，DE是一种模拟生物进化的随机模型，通过反复迭代，使得那些适应环境的个体被保存了下来 DE算法-作者网站: http://www1.icsi.berkeley.edu/~storn/code.html • 维基百科资料库 : https://en.wikipedia.org/wiki/Differential_evolution

列式存储的起源：DSM
Differential File 首先介绍一个概念，叫 Differential File（差异文件，参考《Differential Files: Their Application to the Maintenance 简单介绍一下 Differential File的优势： （1） 在没有Differential File 时，要想防止磁盘损坏导致数据丢失，需要定期全量备份数据库，而有了 Differential File ，只需要一次全量，后边只增量备份 Differential File 就可以了。 通过增量备份很小的 Differential File，则可以避免这个限制。 解法是在备份时维护一个 differential-differential file，即在当前备份状态（原文件-差异文件）上的差异文件。
