Advances in surveillance technology could seriously damage individual privacy unless drastic measures are taken to protect personal data, scientists have said. Richard Thomas, the Information Commissioner, gave warning last year that Britain was "sleepwalking" into a surveillance society. Yesterday the country’s leading engineers developed the theme, fleshing out a dystopian vision that not even George Orwell could have predicted.
They said that travel passes, supermarket loyalty cards and mobile phones could be used to track individuals’ every move. They also predicted that CCTV (close-circuit television) footage could become available for public consumption and that terrorists could hijack the biometric chips in passports and rig them up as a trigger for explosives.
The report by the Royal Academy of Engineering, Dilemmas of Privacy and Surveillance-Challenges of Technological Change, argues that the scientists developing surveillance technology should also think about measures to protect privacy. "Just as security features have been incorporated into car design, privacy-protecting features should be incorporated into the design of products and services that rely on divulging personal information," the report says.
"There is a choice between a Big Brother world where individual privacy is almost extinct and a world where the data are kept by individual organizations or services and kept secret and secure." The report says that shoppers should be allowed to buy goods and services without revealing their identities to the companies that provide them. It argues that travel and supermarket loyalty cards and mobile phones are mines of personal information that should be closely scrutinized to make sure that data is not abused.
Professor Nigel Gilbert, chairman of the report group, said. "In most cases, supermarket loyalty cards will have your name on. Why What is needed in a loyalty card is for the supermarket to know what has been bought so you can get your discounts. "
"Does it need to identify you No, it just needs authentication that you’ve bought the goods. It is the same for Oyster cards on the Tube, some of which you have to register for. These are all apparently small things but people are being required to give away more identification information than is required."
Ian Forbes, the report’s coauthor, said that because footage from CCTV cameras could be digitized and potentially stored for ever, that necessitated greater scrutiny of the controlling networks. Britain has about five million CCTV cameras, one for every 12 people.
The report says: "Give this potential, it cannot be guaranteed that surveillance images will remain private, or will not be altered, misused or manipulated. " The report also gives warning that biometric passports and identity cards would give fresh opportunities to fraudsters and terrorists to read remotely the data chips that they contain. It says that it could be possible to rig a bomb to go off in the presence of a certain person or someone of a particular nationality.
The report proposes that the Information Commissioner should be given extended powers, and that stiffer penalties, including prison sentences, should be introduced for those who misuse personal data. The Commons Home Affairs Select Committee is expected to announce an inquiry into the growing use of surveillance.

地球表面大的部分是海洋。只有用比现在更为精密的仪器才可能对海底进行广泛的研究。因此，科学家对海底环境的了解一定比对地球上其他环境了解的少。如果正确，最能支持上面结论的一项是(）

A．许多山脉完全在海平面下，然而新的水下探测设备产生的三维图像如地面上的山脉的三维图像一样精确

B．强大的水流在海底循环，但是它们运动的总体形态不象气流在陆地上运动的形态那样易于理解

C．与大多数陆地环境相反，海平面的温度条件通常是稳定和一致的，因为太阳光不能透到极深的海平面下

D．非常少的人看过详细的海底延伸区域图，即使这样的图在几乎所有的大图书馆中可以看到
