最近做了一个项目,但是由于我的疏忽,没有给安装程序授权,意思就是说任何人都可以随便使用,导致有对方有个刷小聪明的人在自己的计算上安装了系统,便于自己监测,因为要是跑的楼上楼下3层楼,12个地方,确实挺累人的,但是这个项目的合同上写着按站点给钱的,只给了9个站点的钱,意思就是说别人随便安装是免费的了,给公司造成了损失吧说,关键是,别人随便安装使用会扰乱数据库,直接导致别人操作系统获取数据存在问题.当意识到这个问题,一下没想起来如何来解决这问题,后来打电话给部门经理,经他告知,知道了其中之一的常规办法
1,根据硬盘序列号,来生成授权文件,一听就知道很简单,只是当时着急就灭有想到,在网上找了一些获取硬盘信息的方法,有的给的也不准确,下面把大差不差的代码贴上来,能获取硬盘型号,ID,容量等

我的大体操作是:
1.事先将安装程序的硬盘信息用秘钥对加密好放在授权文件中
2.程序中获取安装程序电脑的硬盘信息用密钥对加密 与授权文件中比较是否村子,存在则授权,否则无权使用程序
这样,对方换电脑啥的也没事,要改只是安装文件夹下的授权文件中的内容
一般买这样的软件给别人一般是有年限的,还有后期维护,所以一直都是卖方控制对方的使用权
