wordpress grace免费主题在线刷seo
前言
由于网站注册入口容易被黑客攻击，存在如下安全问题：
- 暴力破解密码，造成用户信息泄露
- 短信盗刷的安全问题，影响业务及导致用户投诉
- 带来经济损失，尤其是后付费客户，风险巨大，造成亏损无底洞
所以大部分网站及App 都采取图形验证码或滑动验证码等交互解决方案， 但在机器学习能力提高的当下，连百度这样的大厂都遭受攻击导致点名批评， 图形验证及交互验证方式的安全性到底如何？ 请看具体分析
一、 JJ斗地主PC 注册入口
简介： JJ斗地主 是由 竞技世界（北京）网络技术有限公司 开发的一款热门在线棋牌游戏，主打竞技斗地主玩法，同时包含多种创新模式和赛事体系，深受全国玩家喜爱。
1. 注册引导页
2. 会员注页面
二、 安全性分析报告：
JJ斗地主采用的是自己研发的滑动验证码，容易被模拟器绕过甚至逆向后暴力攻击，滑动拼图识别率在 95% 以上。
三、 测试方法：
前端界面分析，这是JJ斗地主自己研发的滑动验证码，网上没有现成的教学视频，但形式都差不多，没什么难度 ， 这次还是采用模拟器的方式，关键点主要模拟器交互、距离识别和轨道算法3部分 。
1. 模拟器交互部分

四丶结语
J斗地主 是由 竞技世界（北京）网络技术有限公司 开发的一款热门在线棋牌游戏，主打竞技斗地主玩法，同时包含多种创新模式和赛事体系，深受全国玩家喜爱，作为受众巨大的网络游戏厂商，技术实力雄厚， 人才济济，采用的是自己研发的滑动验证产品， 在一定程度上提高了用户体验， 不过随着图形识别技术及机器学习能力的提升，所以在网上破解的文章和教学视频也是大量存在，并且经过验证的确有效， 所以除了滑动验证方式， 花样百出的产品层出不穷，但本质就是牺牲用户体验来提高安全。
很多人在短信服务刚开始建设的阶段，可能不会在安全方面考虑太多，理由有很多。
比如：“ 需求这么赶，当然是先实现功能啊 ”，“ 业务量很小啦，系统就这么点人用，不怕的 ” ， “ 我们怎么会被盯上呢，不可能的 ”等等。有一些理由虽然有道理，但是该来的总是会来的。前期欠下来的债，总是要还的。越早还，问题就越小，损失就越低。
所以大家在安全方面还是要重视。（血淋淋的栗子！）#安全短信#

谷歌图形验证码在AI 面前已经形同虚设，所以谷歌宣布退出验证码服务， 那么当所有的图形验证码都被破解时，大家又该如何做好防御呢？
