【中/英】信息安全有新招:脑电波将取代传统密码

2015-07-11

是不是常常会忘记那些不太好记的密码?不用担心,这样的日子即将结束,密码保护貌似又有了新招数。

Always forgetting your not-so “memorable” data? Never fear – the end of the password could be in sight, as our brains might be able to do the work for us.


纽约宾汉顿大学的研究人员正在研究大脑对言语产生反应的原理。研究发现,借助脑电波可以取代密码。

Researchers at Binghamton University, New York, have been looking into the way our brains react to words, and found that brainwaves could be used to replace passwords.


45位志愿者参与了试验,试验检测他们阅读75个首字母缩略词名单时大脑发出的信号,缩略词包括FBI, DVD等。科学家记录他们看每组字母时的产生的反应。结果显示,每位志愿者看不同缩略词时的大脑反应都不尽相同。也就是说,电脑可以通过这些脑电波识别每一位志愿者,且准确率可达到94%。

The scientists looked at the brain signals of 45 volunteers as they read a list of 75 acronyms, such as FBI and DVD, and recorded their reaction to each group of letters. Each participants’ brain reacted differently to the acronyms, meaning that the computer was able to identify each volunteer with 94 percent accuracy.


本周学术期刊《神经计算学》收录的一篇文献写道,当安全系统需要核实用户身份的时候,脑印记就能发挥作用了。

It is this “brainprint” that could be used by security systems to verify a person’s identity, the academics said in the study, which was published in the academic journal Neurocomputing this week.


近些年,由于重大数据泄漏和网络攻击事件屡出不穷,人们越来越关注新奇且精准的身份识别方式。

New and more accurate methods of identification have become increasingly popular over recent years, following a string of high-profile data breaches and cyber-attacks.


目前可用的保密方法包括指纹、声音、面部识别和生物识别。

Security measures now available including fingerprint, voice, face and biometric identification.


但是,该篇报告的共同作者,宾汉顿大学心理语言学副教授Sarah Laszlo表示,相比之下,脑印记的身份识别方法比现有的方法更具优势。

But Sarah Laszlo, assistant professor of psychology and linguistics at Binghamton University and co-author of the report, said “brainprints” had some benefits over these other methods of identification.

Sarah在新闻发布会上称:“如果某人的指纹被盗,但他就无法长出新手指来替换被盗指纹,因为指纹将伴随人一生,无法撤销。”

“If someone’s fingerprint is stolen, that person can’t just grow a new finger to replace the compromised fingerprint — the fingerprint for that person is compromised forever. Fingerprints are ‘non-cancellable’,” she said in a release.


“而另一方面,脑印记确是可删除的。用户可以重置脑印记,所以,脑印记不太可能遭受恶意攻击。”

“Brainprints, on the other hand, are potentially cancellable. So, in the unlikely event that attackers were able to steal a brainprint, the authorized user could ‘reset’ their brainprint.”


然而,同为宾汉顿大学的金展鹏教授透露,目前脑扫描还不完善,尚不能进行大范围使用。

However, Zhanpeng Jin, who is also at Binghamton University, expressed reservations over the wide-scale use of brain scans.


金教授补充道:“我们更倾向于将该系统应用于高机密地理位置,例如五角大楼,空军研究实验室等。因为那些地方的授权用户人数较少。”

“We tend to see the applications of this system as being more along the lines of high-security physical locations, like the Pentagon or Air Force Labs, where there aren’t that many users that are authorized to enter,” he added.
