CNN News:车牌扫描器到底涉不涉及个人隐私泄露问题？

License plate scanners - they are intended to keep crime off the road. A police sergeant says you`ll call them a success if your car is ever stolen and they help get it back. Civil liberties advocate say there could be an invasion of privacy, if they are used to keep tabs on you wherever your drive.

车牌扫描仪是用来扫描犯罪车辆车牌号阻止其上路的先进设备。一名警官称如果你的车被偷了它可以帮你找回来，这就是这个新设备成功的地方。公民自由倡导者称这个设备可能会对个人信息进行侵犯，如果这个设备被用来监视系统的话，无论你在那里都会受到监视。

Some police departments delete the data they gather from them, some don`t. All are hoping it will curb crime.

一些警察部门删除了从设备上获取的数据信息，一些则没有。所有人都希望这些信息可以遏制犯罪现象的发生。

Since the early 1990s, crime rates have steadily declined across the country.

自上世纪90年代初，全国犯罪率持续下降。

One possible explanation - smarter data driven policing.

一种可能的解释就是智能数据帮助警方遏制犯罪事件的发生。

Here in Los Angeles, the LAPD is embracing new technologies and big data analytics like never before, changing the way we fight crime.

在洛杉矶，洛杉矶警局正在进行一场前所未有的新技术和信息分析行动，改变了以往我们打击犯罪的方式。

Watch commander Sergeant Kennedy showed us how big data analysis is changing the force.

观看了军士Sergeant Kennedy向我们展示的超大数据库是怎样帮助了我们改变工作方式。

This is our license plate reader.

这是我们的车牌阅读器。

We have three cameras attached to the light bar.

我们有三个相机连接到了光杆。

License plate readers installed on patrol cars have become common place. And they automatically scan every license plate they drive by.

车牌阅读器被安装在巡逻车上，可以扫描任何一辆经过的车辆车牌。

It goes to the Sacramento database to check for California vehicle system, to see if it`s stolen, or if there`s a warrant on it for some reason.

这些数据被传输到萨克拉门托数据库来检查加利福尼亚的车辆系统进而辨识车辆是否是被偷车辆，或许是否有一个正当的担保。

On alert. $30,000 award. Parked car that we just passed. That`s right behind us.

出现警告，这是一辆悬赏三万美元的车。就是我们刚刚经过的停着的那辆车，就在我们的后面。

Over the course of a day, the LAPD can scan tens of thousands of license plates across the city. At the LAPD`s real time analysis and critical response division, those license plates scans are fed into a game- changing data mining system called Palantir.

经过一天的巡逻，洛杉矶警局可以扫描数以万计的车牌信息。在洛杉矶警局实时分析和应急部门，这些车牌扫描器进入到了一个游戏，一个可以改变数据挖掘系统称之为Palantir的情报分析公司。

A powerful application that can claim the CIA as an early investor.

一个宣称CIA早期投资者的强大应用。

Palantir is a federated search system, it combines data sets, allows us to access them very quickly. With a single key stroke, you get the effect of a 30 person taskforce.

该公司是一个联合搜索系统，结合了各种数据集可以使我们非常快速的访问。只需要一下按键就相当于30人小组的工作效果。

After searching over 100 million data points, Palantir displayed an impressive web of information on one burglary suspect. Creating intuitive graphs linking him to cell phone numbers, arrest records, known associates and past addresses. They could even track the suspect`s past locations based on previous license plate scans.

经过对一亿个数据搜索之后，Palantir就会显示出一个符合条件的盗窃嫌疑人信息。直观图形信息直接连接到他的手机，逮捕记录，已知同事和过去的地址。他们甚至可以追踪到犯罪嫌疑人过去的住址。

If we are searching for him, we don`t have to search all of L.A. County. We know where he frequents.

如果我们正在搜寻他，我们不需要对真个洛杉矶城市进行搜寻，我们知道他常去的地方。

Anybody who is a vehicle owner is then in Palantir?

每一个车主信息都在Palantir里储存着么?

Anybody who is a vehicle owner in a public place and has passed a license plate. Really, will be in our data set. We cannot just go searching for you or anyone else without a reason. Because we have a lot of data for people who`ve done nothing.

每一个在公共场合经过车牌扫描器扫描的车主信息都在里面。这是真的，都在我们的数据集里。我们在没有许可的条件下不允许搜寻个人信息。因为我们这里也有无辜群众的数据信息。

For those people who`ve done nothing, the ACLU of Southern California believes that LAPD`s license plate readers may be violating civil liberties.

对于无辜群众来讲，南加里福尼亚的美国公民自由联盟称数据信息可能会遭到车牌扫描器的侵犯。

A system of license plate readers that`s persuasive enough to really track the movements of every, every car in the city in reasonable detail would effectively substitute for GPS trackers for everybody.

车牌扫描器的系统确实可以追踪到每一辆经过扫描汽车的行踪，在合理的细节车牌扫描器会代替GPS追踪每个人的定位。

The public should be the one`s deciding what the proper balance is between their privacy rights and their public safety.

公众应该决定个人权利和公共安全之间的权衡问题。

The LAPD believes the public wants Palantir on its side.

洛杉矶警局称相信公众会像让Palantir为自己的安全保驾护航。

You want to have the effect of 30 detectives working that burglary or that auto theft. It is hugely important to make those cases solvable.

你会想要一个拥有30名警员对盗窃或者盗窃汽车案件工作力量的设备，这对于解决犯罪案件来讲是非常重要的。
