Your camera is snatched. Will you ever see it a-gain? Probably not. But it may send postcards from its new owner. The【C1】______of recovery of lost or stolen cameras have improved【C2】______newer devices combined with online photo-sharing services create a digital track one can【C3】______with the right tools.
Dozens of cameras from major manufacturers【C4】______the serial number found on a camera’s body into its software as well. The serial number is then included in the metadata with which every picture taken by the camera is tagged. When a photo is uploaded at sites like Flickr, they can, therefore, be【C5】______and indexed. Mr. Westin’s company, which makes the Gadget-Trak theft-recovery applications, has begun to create a searchable image database for lost cameras. When the owners upload the tagged photos they provide the【C6】______link. Once the database is established, the company will compare it with that of a list of missing serial numbers【C7】______by police.
Of course, even if a camera’s serial number crops up,【C8】______the device’s current location need not be【C9】______. However, there is also good news: posted pictures may give clues【C10】______its current location. Even more helpfully, more and more cameras now come 【C11】______a GPS receiver for inserting geographical coordinates into a picture’s metadata. Flickr won’t show the uploading account holder such information【C12】______a user explicitly permits it. Photos posted in other ways, 【C13】______, may leak this information more casually. With enough such【C14】______, police could ask a photo service or obtain a(n)【C15】______to retrieve location data stored in the user’s account.
Mr. Westin says that photographers can examine an image taken by their camera【C16】______losing it and extract the serial number. He wants to release a tool to make this【C17】______. All this is, of course, a double-edged【C18】______. Any information that helps find stolen
【C19】______may also be used to track camera owners’ activities. Tools to【C20】______such data before photos are uploaded to the internet are available. And thieves know it.
【C13】
选项
A、otherwise
B、though
C、moreover
D、so
答案
B
解析
上文提到“得到用户的许可,Flickr网站才显示这些信息”,而下文提到“其他方式上传的照片可能会泄露这些信息”,前后两句之间有转折关系,故选B项though“虽然,然而”,可表让步或转折关系。
