What happens if a face recognition system is NOT secure?

有很多可以攻击的地方。

part 1: anti-spoofing -> face presentation attack detection

• Jukka Maatta , Abdenour Hadid , Matti Pietikainen , “Face Spoofing Detection From Single Images Using Micro Texture Analysis”, IJCB 2011 基于LBP的

CVPRW2020

结构光

3D mask attack

这个很具有挑战性

• 
• 提供一个人脸照片，就可以很简单做3Dmask
• 特别真实

一个真实的例子

我去这么厉害的么？？？？？？？

我们最近的工作

只是一个overview，需要的话看详细论文。

How to increase the robustness of rPPG based Face Anti spoofing?

限制/不足

• 时间太长了，10秒钟，3秒可不可以啊？？好像效果不是很好
• 所以我们设计了另外一个
• 

做了一个实时系统

另外一个工作

问一个问题

如果我们不知道攻击类型呢？

所以我们设计了domain-generalization

meta learning?

第一次meta learning 应用在anti-spoofing

Dataset

欢迎下载:

Part 2

现在的解决方案

我们的工作

conclusion

• Biometrics security and privacy is an important issue for practical biometrics systems

• Research work in fake biometrics detection and biometrics template protection are discussed

• Security like a “cat and mouse” game

• More and continuous efforts are required

QA

问：Hello professor. Thank you for your presentation. There are some ECG-based authentication methods now. According to your research, can it be a effective way to use rPPG to recognize identity alone or help other features(e.g. face) ?

• ECG不是很方便啦
• 人PPG 远距离就可以

问： 未来的FR，安全可信赖么？

• biometric -> identity science

问： 有使用IR之类的做anti-spoofing

• 我们使用过NIR啦

问：
hello professor. Thank you for your presentation. I wanna ask question that what is the performance of this algorithm about 3D-mask anti spoofing in the low piexl-level camera like mobile phone camera?

• 手机很好的啦，相机
• 最大的挑战是环境

问：Hello professor P.C, thanks so much for the talk. Could you kindly share your thougths on bridge the gap between biometrics and conventional cryptosystem? such as the combination of biometric with symmetric password system or asymmetric cryptosystem?

• 这个已经有人使用
• 我大部分是anti-spoofing
• 我们未来要做，使用deep learning based hashing

问： deep fake?

• digital manipulation
• 我没有做过这个，Liu Xiaoming 可能会讲这些。

问： 戴口罩的人，而且又走很快，咋办

• 这个还真的是困难，如果人走很快的话，就没办法，是个open question

问：make up 怎么区分呀

• arun ross 有做过一个数据集
