[单项选择]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
A. the quirks of the keys of the typewriters
B. the drums and mirrors inside the printers
C. the subtle defects of printing devices
D. the special skills of the experts
