Recently, according to growth and concentration of population in urban area, congested situations at several railway stations in rush
hour become a serious social issue. Therefore, designing the stat...
In this paper, we proposed a fast and robust unsupervised framework for anomaly detection and localization in crowed scenes. Our method avoids modeling the normal state of the crowds which is a very c...
基于IPv6的接收者匿名Crowds系统
匿名通信 IPv6协议 接收者匿名
2009/11/30
基于下一跳重路由方式的Crowds匿名通信系统存在较多缺点。提出基于IPv6协议的Crowds系统，解决发送者与最后一跳的秘密共享问题。理论分析和实验结果表明，该系统的抗攻击能力与源路由方式相等，实现了接收者匿名，减少了通信延迟。
