The Recorded World

    As cameras become ubiquitous(普遍存在的.and able to identify people，more safeguards on privacy will be needed． 

A. “This season there is something at the seaside worse than sharks，”declared a newspaper in 1890.“It is the amateur photographer．”The invention of the handheld camera shocked the 19th—century society，as did the“Kodak fiends”(柯达狂人.who patrolled beaches snapping sunbathers． 
B. More than a century later，amateur photography is once more a troubling issue．Citizens of rich countries have got used to being watched by closed．circuit cameras that guard roads and cities．But as cameras shrink and the cost of storing data falls sharply，it is individuals who are taking the pictures． 
C. Some 10，000 people are already testing a prototype of Google Glass，a miniature computer worn like eveglasses．It aims to have all the functions of a smartphone in a device put on a person’s nose.Its flexible frame holds both a camera and a tiny screen，and makes it easy for users to take photos，send messages and search for things online． 
D. Glass may fail，but a wider revolution is under way．In Russia，where insurance fraud is commonly seen，at least l million cars already have cameras on their dashboards(仪表盘.that film the road ahead．Police forces in America are starting to issue officers with video cameras，pinned to their uniforms，which record their 
interactions with the public．Collar—cams help anxious cat—lovers watch their wandering pets carefully. Paparazzi(狗仔队.have started to use drones to photograph celebrities in their gardens or on yachts. Hobbyists are even devising clever ways to get cameras into space． 
E. Ubiquitous recording can already do a lot of good．Some patients with brain injuries have been given cameras：looking back at images can help them recover their memories．Dash—cams can help resolve insurance claims and encourage people to drive better．Police—cams can discourage criminals from making groundless complaints against police officers and officers from abusing criminals．A British soldier has just been convicted of murdering a wounded Afghan because the act was captured by a colleague’s helmet—camera. Videos showing the line of sight of experienced surgeons and engineers can help train their successors and be used in liability disputes．Lenses linked to computers are reading street—sign sand product labels to partially sighted people． 
F. Optimists see broader benefits ahead．Plenty of people carry activity trackers，worn on the wrist or placed in a pocket，to monitor their exercise or sleep patterns；cameras could do the job more effectively，perhaps also spying on their wearers’diets．“Personal black boxes’’might be able to transmit pictures if their owner falls victim to an accident or crime．Tiny cameras trained to recognise faces could become personal digital assistants，making conversations as searchable as documents and e—mails．Already a small band of“life. logger(生活记录器）stored years off ootage(镜头.into databases of“e—memories”． 
G. Not everybody will be thrilled by these prospects．A perfect digital memory would probably be a pain, preserving unhappy events as well as cherished ones．Suspicious spouses and employers might feel entitled to review it． 
H.The bigger worry is for those in front of the cameras，not behind them．School bullies already use illegal snaps from mobile phones to embarrass their victims．The web is full of secret photos of women，snapped in public places．Wearable cameras will make such immoral photography easier．And the huge，looming issue is the    growing sophistication of face-recognition technologies，which are starting to enable businesses and governments to get information about individuals by searching the billions of images online．The combination of cameras everywhere---in bars，on streets，in offices,on people’s heads--with the algorithms(算法.run by social networks and other service providers that process stored and published images is a powerful and alarming one．We may not be far from a world in which your movements could be tracked all the time．where a stranger walking down the street can immediately identify exactly who you are． 
I. Well,we still strongly held beliefs that technological progress should generally be welcomed．not feared runs up against an even deeper impulse，in favour of liberty．Freedom has to include some fight to privacy：if every move you make is being recorded，liberty is limited． 
J. One option is to ban devices that seem annoying．The use of dashboard cameras is forbidden in Austria. Drivers who film the road can face a €10，000($13，400.fine．But banning devices deprives people of their benefits．Society would do better to develop rules about where and how these technologies can be used,just as it learned to cope with the Kodak fiends． 
K. For the moment，companies are behaving in a cautious way．Google has banned the use of face—recognition in apps on Glass and its camera is designed to film only in short bursts．Japanese digital camera．makers ensure their products emit a shutter sound every time a picture is taken．Existing laws to control stalking of harassment can be extended to deal with peeping drones． 
L. Still，as cameras become smaller，more powerful and ubiquitous，new laws may be needed to Dreserve liberty. Governments should be granted the right to use face—recognition technology only where there is a clear public good(identifying a bank robber for instance.．When the would．be identifiers are companies or strangers in the street，the starting—point should be that you have the right not to have your identity automatically revealed．The principle is the same as for personal data．Just as Facebook and Google should be forced to establish high default settings(默认系统设置.for privacy(which can be reduced at the user's request.，the new cameras and recognition technologies should be regulated so as to let you decide whether you remain anonymous(匿名的.or not． 
M. Silicon Valley emphasises the liberating power of technology--and it is often fight．But the freedom that a small device gives one person can sometimes take away liberty from another．Liberal politicians have been lazy about defending the idea of personal space，especially online．The fight should start now．Otherwise，in the blink of an eye，privacy could be gone．
