No document is safe any more. Faking once the domain of skilled deceivers that used expensive engraving(雕刻)and printing equipment, has gone mainstream since the price of desktop-publishing systems has dropped. In ancient times, faking was a hanging offence. Today, desktop counterfeiters have little reason to worry about prison, because the systems they use are universal and there is no means of tracing forged documents to the machine that produced them. This, however, may soon change thanks to technology development by George Chiu, an anti-faking engineer.
His approach is based on detecting imperfections in the print quality of documents. Old-school court scientists were able to trace documents to particular typewriters based on quirks(瑕疵)of the individual keys. He employs a similar approach, exploiting the fact that the rotating drums and mirrors inside a printer are imperfect pieces of engineering which leave unique patterns of banding in their products.
Although these patterns are invisible to the naked eye, they can be detected and analyzed by computer programs, and it is these that Dr. Chiu has spent the past year devising. So far, he cannot trace individual printers, but he can tell pretty reliably which make and model of printer was used to create a document.
That, however, is only the beginning. While it remains to be seen whether it will be possible to trace a counterfeit(伪造的)document back to its guilty creator on the basis of manufacturing imperfections, Dr. Chiu is now working out ways to make those imperfections deliberate. He wants to modify the printing process so that unique, invisible signatures can be incorporated into each machine produced which would make any document traceable.
Ironically, it was after years of collaborating with printing companies to reduce banding and thus increase the quality of prints, that he came up with the idea of introducing artificial banding that could encode identification information into a document. Using the banding patterns of printers to secure documents would be both cheap to implement and hard, if not impossible, for those without specialist knowledge and hardware to hide out.
Not surprising, the American Secret Service is monitoring the progress of this research very closely, and is providing guidelines to help Dr. Chiu to travel in what the service thinks is the right direction, which is fine for catching criminals. But how the legal users of printers will react to Big Brother being able to track any document back to its source remains to be seen. [br] By saying "No document is safe any more", the author probably means______.
选项
A、cheap printers make it easier to forge documents
B、the American Secret Service can trace any document
C、every printed document will be secretly marked out
D、counterfeiters have more advanced technologies to use
答案
A
解析
语义理解题。定位句提到,任何文件都将不再安全。造假本来是使用昂贵的篆刻和印刷机器的技术娴熟的欺骗者才能做的事,现在已经由于台式印刷系统价格降低而成为主流。这里强调了造假的普遍性,由此推知A)“价格低廉的打印机使伪造文件更容易”正确。
