“Study Finds Web Antifraud Measure Ineffective”
Internet security experts have long known that simple passwords do not fully defend online bank accounts from determined fraud artists．Now a study suggests that a popular secondary security measure provides little additional protection．
The study,produced jointly by researchers at Harvard and the Massachusetts Institute of Technology,looked at a technology called site-authentication images．In the system,currently used by financial institutions like Bank of America,ING Direct and Vanguard,online banking customers are asked to select an image,like a dog or chess piece,that they will see every time they log in to their account．
The idea is that if customers do not see their image,they could be at a fraudulent Web site,dummied up to look like their bank's,and should not enter their passwords．
The Harvard and M．I．T．researchers tested that hypothesis．In October,they brought 67 Bank of America customers in the Boston area into a controlled environment and asked them to conduct routine online banking activities,like looking up account balances．But the researchers had secretly withdrawn the images．
Of 60 participants who got that far into the study and whose results could be verified,58 entered passwords anyway．Only two chose not to log on,citing security concerns．

“研究发现网络防欺诈措施是无效的”
互联网安全专家们早就知道,使用简单的密码无法充分保护网上银行账户免受恶意欺诈者攻击.
现在有一项研究指出,一种流行的辅助安全措施可以提供一些额外的保护.
哈佛大学和麻省理工学院的研究人员联合研究了网站认证图像技术.目前使用该系统的金融机构,如美国银行（Bank of America）,网上银行和先锋盾,每次他们登录到自己的帐户时,网上银行客户被要求选择一个图像,比方说一只狗或一个象棋子的图像.
该想法是,如果客户没有看到图像,他们访问的可能是一个欺诈网站,装扮成他们要登录的银行网站,这时就不要输入自己的密码.
哈佛大学和麻省理工学院的研究人员测试了这一假定.10月份,他们请67个美国银行的客户在波士顿地区进入一个受控制的环境,并要求他们进行例行的网上银行业务,例如检查帐户余额.但研究人员秘密撤回了上述图像.
在60名参与了进一步试验,其结果可以验证的客户中,58个输入了密码.只有两个选择不登录,因为他们担心安全问题.
