5、 accounts you need for work arent filled with intention. With increasing security requirements, its likely your word/number combinations are becoming even less memorable. But new research suggests it may not be long before you wont need to memorize passwords.“Brainprint”, published in Neurocomputing
6、, reveals that the brains reaction to certain words could be a unique identifying code - like a fingerprint - that could eventually replace passwords.In a small experiment, the researchers measured the brains signals of 45 volunteers as they read through a list of 75 acronyms such as FBI and DVD. Th
7、e word-recognition response differed so much between each participant that a second experiment using a computer program could identify each one with 94% accuracy.Its not enough to feel totally secure, but promising enough to hint at the future of securing sensitive information.The advantage of using
8、 such a biometric system(生物识另U系统)is that it can be used for continuous verification(验证),New Scientist points out. Passwords or fingerprints only provide a tool for one-off identification. Continuous verification could in theory allow someone to interact with many computer systems at the same time or
9、 even with a variety of intelligent objects, without having to repeatedly enter passwords for each device.As Hollywood has illustrated, its simply a matter of cutting off a finger to steal that persons identity. “Brainprints, on the other hand, are potentially cancellable J said Sarah Laszlo, assist
10、ant professor of psychology and linguistics at Binghamton University and co-author of the study, “So, in the unlikely event that attackers were actually able to steal a brainprint from an authorized user, the authorized user could then reset their brainprint.Until now, brain signals have been a chal
11、lenge to understand. This experiment leaped over the obstacle by focusing on the brainwaves from the specific area that reads and recognizes words. The signal is therefore clearer and easier to measure.The problem, so far, is that the brain signal is still not as accurate as scanning someones finger
12、print, and initially requires sticking diodes(二极管)on your head in order to get a read. Thats ok, according to Zhanpeng Jin, assistant professor at Binghamton University and coauthor of the study, because brainprint isnt going to be mass-produced any time soon. He says the researchers foresee its use
13、 at places such as the Pentagon, where the number of authorized users is small, and they dont need to be continuously verified the way you do to access your mobile device or email.Better keep your memory sharp, at least a little while longer.试卷第10页,共14页63.
