google承认搜集wi-fi数据
google承认利用street view采集车搜集未加密wifi信息Google admits wi-fi data collection blunder
Google has admitted that for the past three years it has wrongly collected information people have sent over unencrypted wi-fi networks.
The issue came to light after German authorities asked to audit the data the company's Street View cars gathered as they took photos viewed on Google maps.
Google said during a review it found it had "been mistakenly collecting samples of payload data from open networks".
The admission will increase concerns about potential privacy breaches.
These snippets could include parts of an email, text or photograph or even the website someone may be viewing.
In a blogpost Google said as soon as it became aware of the problem it grounded its Street View cars from collecting wi-fi information and segregated the data on its network.
It is now asking for a third party to review the software that caused the problem and examine precisely what data had been gathered.
"Maintaining people's trust is crucial to everything we do, and in this case we fell short," wrote Alan Eustace, senior vice president of engineering and research.
"The engineering team at Google works hard to earn your trust - and we are acutely aware that we failed badly here."
'Pushing the envelope'
Google said the problem dated back to 2006 when "an engineer working on an experimental wi-fi project wrote a piece of code that sampled all categories of publicly broadcast wi-fi data".
That code was included in the software the Street View cars used and "quite simply, it was a mistake", said Mr Eustace.
"This incident highlights just how publicly accessible, open, non-password protected wi-fi networks are today."
Dan Kaminsky, director of penetration testing for security firm Ioactive, said there was no intent by Google.
"This information was leaking out and they picked it up. If you are going to broadcast your email on an open wi-fi, don't be surprised if someone picks it up."
John Simpson, from the Consumer Watchdog, told the BBC: "The problem is have a bunch of engineers who push the envelope and gather as much information as they can and don't think about the ramifications of that."
Dr Ian Brown, an expert on privacy and cyber security at the Oxford Internet Institute, told BBC News the wi-fi data collection was part of an idea to accurately map a user's location on Google Map and Street View.
"The idea was to use to the different signals and strengths from wi-fi and phones to position a users - think of it as a sort of GPS.
"However, there are concerns in many countries that Google has broken numerous data protection and privacy laws by collecting this data and I expect a clutch of lawsuits to follow," he said.

不是太明白这个Data Collecting的作用。
有谁解释一下，为什么写这么一个功能？

去问Google:lol我猜是和Google想要更精确的定位有关，把IP, mac等信息和方位联系起来，或者和分析用户行为，投放广告等等.... 有没有更深入的用处？

用来蹭网？;P 不知道是不是为了给街景功能添加一个免费wifi热点信息。
我觉得这个数据收集侵犯隐私倒不至于引发很严重的问题（用未加密的wifi信号的人，本身就不关注自己的隐私是否会被人收集），如果大家都爱上gmail之后，google要真想收集大家的隐私，从gmail入手更有价值。

那就彻底岳不群了:funk: 看着俺的山寨ipad，俺突然明白了google搜集这个数据干嘛用。如俺在山寨ipad评测报告里面说的，我那个里面装的，实际上就是一个手机版本的android，所有功能都是手机的，比如，开机的时候，会显示“不在服务区”:L :L
打开google搜索页面，我注意到在搜索栏的下面，居然显示着俺住的区的名字，要知道我的ipad只是通过wifi上网而已。我一下明白了，google搜集wifi数据，应该是希望通过ip地址来实现定位吧？ 根据位置搜索是现在手持设备的一大功能，在Apple iPhone, Google Android上都有。
iPhone上会问你要不要把位置信息提供给目标程序，
Google Android好象也有类似的提供。
至于定位的方法，现在主要有几种
一是GPS定位，这个就不用说了。
二是基站定位，听说在美国很好用，可以精确定位到每个block，在商业区，基站定位比GPS定位还好用。但这种定位只限于有手机模块的设备。
三是IP定位。事实上按照互联网设计的特点，IP是不能定位的，最简单的就是通过vpn接入后，相邻的IP距离可以相隔几万公里，但一般情况下还是可以近似定位。
而IP定位又有两种方式，一种是终端IP地址的定位，二是第一个网关IP地址定位。目前国外使用的应该主要是第二种，比如你通过TPG接入，第一个TPG网关的位置
往往就是你所在的suburb的位置，所以这个定位的精度在suburb。
但还有更无耻的定位，是第一种，就是终端IP地址定位，目前国内有这样的数据库，起源于00年左右建立的全国IP地址免费数据库。
这类定位可以精确到每一幢楼。
由于现在SNS的流行，导致大量的网民会在SNS网站上手动更新自己的location，这类信息也可以用于定位推理。比如有一个用户，他在 1. abc st.，那么在
这个用户IP邻近或相同的地方，也应该差不多位置。
第三种是依据搜索特点来定位，依据是你一般会搜索和你相关的信息，这个信息中有一大部分是位置相关信息，通过大量的学习模型，可以把你这个用户的位置计算出来。
至于利用家用路由器来获取用户具体位置的做法，应该也是有可能性的。
