Model hand cheated all fingerprint scanner: 3D printing concern-IT information

3D printing technology has brought many benefits and would encourage more innovation. But it's also easy for some unlawful purpose. Using 3D printing technology a very realistic imitation of a fingerprint prosthetic hand, you can use it to fool the fingerprint scanner in the security system. It sounds a bit like a spy movie, but Anil Jain, Professor at Michigan State University is to become a reality.

Professor Jain has been studying a fingerprint scanner security and how to improve them in order to avoid crime. Professor Jain's team created a 3D print made by the fingerprint test models of the hand. Results show that such a lifelike model of fingerprint hand cheated all fingerprint scanning systems.

The team is using a Stratasys Objet350 Connex 3D printer, with ultra high resolution, three-dimensional model can be constructed out of the surface of the finger to ensure finger print fingerprint on every peak and Valley in their appropriate locations.

Jain said: "as with any optical device, fingerprint or hand scanners need to be calibrated, but at present there is no standard way to calibrate them. ”

Test results showed that the security systems developers need to put more effort into the fingerprint scanning systems in the future on the identification of the true and false hand, or towards more security on retinal scanning technology.


模型手骗过所有指纹扫描器:3D打印引发担忧 - IT资讯

3D打印技术带来了很多好处并将鼓励更多的创新。但这也为一些不法用途带来了便利。比如利用3D打印技术仿制出一只十分逼真的带指纹假手,就可以用它来骗过安全系统里的指纹扫描仪。这听起来有点像特工电影,但密歇根州立大学Anil Jain教授就将其变成了现实。

Jain教授一直在研究指纹扫描仪的安全性以及如何对其进行改进以避免犯罪。Jain教授的团队创建了一个用3D打印制成的带指纹手部模型进行测试。结果显示,这样一个栩栩如生的带指纹手部模型居然骗过了所有的指纹扫描系统。

该团队所使用的是Stratasys Objet350 Connex 3D打印机,拥有超高分辨率,可构造出手指表面的三维模型,保证打印出的手指指纹每个峰谷都处在各自合适的位置上。

Jain教授说:“与任何光学设备一样,指纹或手部扫描仪需要进行校准,但目前还没有一套标准方法来对它们进行校准。”

测试结果表明,安全系统的开发人员未来需要将更多精力投入指纹扫描系统对真假手的辨别上,或是转向更安全的视网膜扫描技术上。
