iPhone5S指纹识别会是数字密码的终结吗？
<p>苹果公司最近发布的<span word="iPhone">iPhone</span>5<span word="S">S</span>带有指纹识别功能，该公司表示这种接触式身份识别系统会彻底革新智能手机安全功能，取代传统的密码体系。不过，相关领域的研究人员却表示，指纹识别技术并不完美，“并没有比四个数字的密码安全多少”。苹果主管全球产品营销的高级副总裁席勒在新品发布会上表示，智能手机用户中有一半不给手机设密码，指纹识别功能为他们提供了一个更便捷、更有趣的安全选择。该功能不但能用于手机解锁，还能用于<span word="App">App</span> <span word="Store">Store</span>购物支付。可是，安全研究人员指出，指纹识别也有安全隐患；我们所到之处都会留下我们的指纹，一旦有人起歹念，复制了我们的指纹，那么这个功能就失效了。另外，研究人员也提醒，指纹信息不能像密码那样可以随时更换，用指纹识别作为唯一安全保障并不明智。</p><p><span word="Apple">Apple</span> <span word="unveiled">unveiled</span> <span word="the">the</span> <span word="fingerprint">fingerprint</span> <span word="scanner">scanner</span> <span word="on">on</span> <span word="its">its</span> <span word="iPhone">iPhone</span> 5<span word="S">S</span> <span word="on">on</span> <span word="Tuesday">Tuesday</span> <span word="with">with</span> <span word="bold">bold</span> <span word="claims">claims</span> <span word="about">about</span> <span word="its">its</span> <span word="high">high</span> <span word="levels">levels</span> <span word="of">of</span> <span word="encryption">encryption</span> <span word="and">and</span> <span word="security">security</span>.</p><p><span word="The">The</span> <span word="firm">firm</span> <span word="even">even</span> <span word="suggested">suggested</span> <span word="that">that</span> <span word="its">its</span> <span word="Touch">Touch</span> <span word="ID">ID</span> <span word="system">system</span> <span word="could">could</span> <span word="revolutionize">revolutionize</span> <span word="smartphone">smartphone</span> <span word="security">security</span> <span word="and">and</span> <span word="replace">replace</span> <span word="the">the</span> <span word="traditional">traditional</span>, <span word="everyday">everyday</span> <span word="password">password</span>.</p><p><span word="Yet">Yet</span> <span word="security">security</span> <span word="researchers">researchers</span> <span word="have">have</span> <span word="warned">warned</span> <span word="that">that</span> <span word="the">the</span> <span word="technology">technology</span> <span word="is">is</span> <span word="not">not</span> <span word="perfect">perfect</span>, <span word="with">with</span> <span word="one">one</span> <span word="adding">adding</span> <span word="that">that</span> <span word="it">it</span> '<span word="provides">provides</span> <span word="little">little</span> <span word="added">added</span> <span word="security">security</span> <span word="over">over</span> <span word="a">a</span> <span word="four">four</span>-<span word="digit">digit</span> <span word="code">code</span>.'</p>
