新しいセキュリティ認証技術！？ ― brainprint

年金機構の情報流出事件が世間を騒がせています。大切な情報を守るのにパスワードというものはもはや古いのかもしれません。

パスワードよりも強力な認証技術として指紋認証があります。さらには、目の虹彩を使った認証技術といったものも存在します。この分野は日進月歩です。さらに発展して、"brainprint"なる技術も目下研究中ということですが、果たしてその中身とは？


We have all used passwords at one time or another to protect our accounts and identities. Some may even use fingerprints when a higher level of security is required. In the future however, you may never need to use passwords or fingerprints ever again due to the research being done on our brain waves.

Researchers at Binghamton University have found a way to verify a person's identity based on how their brain reacts to certain words according to a new study published by the academic journal Neurocomputing. In the research study, participants were read different acronyms, and it turned out that each participant's brain reacted differently to each acronym. The researchers have suggested through their findings that each person's 'brainprint' can be used by security systems to identify one's self.

記事によりますと、我々の脳が発している脳波を使った個人認証技術が目下研究されているそうです。

"brainprint"という単語は、"fingerprint"をもじったものでしょう。

"fingerprint"は指先の模様（指紋）を指しますが、"brainprint"は脳組織が織り成す模様のことではなく、特定の言葉に対して脳が示す反応を利用したもののようです。


We’ve heard a lot about how our bodies—our faces, our irises, even our heartbeats—will replace passwords. Now, a group of neuroscientists are adding another body part to that list: the brain. Or more specifically, the brain’s response to certain words.
