Apple針對了近日吵翻天的iPhone定位資訊以及用戶隱私問題發出了正式的官方新聞稿回應,基本上傳達的幾個重點……

以下是新聞稿原文+翻譯:

 


 

Apple Q&A on Location Data

Apple would like to respond to the questions we have recently received about the gathering and use of location information by our devices.

Apple想回應關於由我們的裝置收集與使用地理位置資訊的問題。

 

  1. Why is Apple tracking the location of my iPhone?

Apple is not tracking the location of your iPhone. Apple has never done so and has no plans to ever do so.

1.為何Apple追蹤我的iPhone的位置?

Apple並沒有追蹤您iPhone的位置。Apple從不這麼做,以後也永遠沒有計畫去做這樣的事。

 

  1. Then why is everyone so concerned about this?

Providing mobile users with fast and accurate location information while preserving their security and privacy has raised some very complex technical issues which are hard to communicate in a soundbite. Users are confused, partly because the creators of this new technology (including Apple) have not provided enough education about these issues to date.

2. 那麼,為何所有人都如此關心這問題?

提供手機使用者快速、精確的定位服務,同時保護使用者的安全與隱私已經成為非常複雜的技術問題,這個問題非常難以在不斷重複傳播的媒體之間與大眾溝通。使用者們會感到困惑,部分是因為這種新技術的創造者(包含Apple)還沒有在這些議題方面提供足夠的宣導。

 

  1. Why is my iPhone logging my location?

The iPhone is not logging your location. Rather, it’s maintaining a database of Wi-Fi hotspots and cell towers around your current location, some of which may be located more than one hundred miles away from your iPhone, to help your iPhone rapidly and accurately calculate its location when requested. Calculating a phone’s location using just GPS satellite data can take up to several minutes. iPhone can reduce this time to just a few seconds by using Wi-Fi hotspot and cell tower data to quickly find GPS satellites, and even triangulate its location using just Wi-Fi hotspot and cell tower data when GPS is not available (such as indoors or in basements). These calculations are performed live on the iPhone using a crowd-sourced database of Wi-Fi hotspot and cell tower data that is generated by tens of millions of iPhones sending the geo-tagged locations of nearby Wi-Fi hotspots and cell towers in an anonymous and encrypted form to Apple.

3. 為何我的iPhone記錄我的位置?

iPhone並沒有記錄您的位置。相反地,它會維護您周遭環境中的Wi-Fi熱點與您電信公司的基地台資料庫,來幫助iPhone在您要求時能快速、精確地計算定位。其中部分被記錄的基地台位置可能會離您的iPhone超過一百英哩以上。

僅用GPS衛星資訊來計算手機的位置可能會花費數分鐘的時間。iPhone可以使用Wi-Fi熱點以及手機基地台資料來快速尋找GPS衛星,進而將定位時間縮減到只有數秒鐘的時間。甚至當GPS訊號無法使用時(例如室內或是地下室),可以只使用Wi-Fi熱點與手機基地台進行三角定位。

這些計算是使用記錄Wi-Fi熱點與手機基地台的集體資料庫。此資料庫是由數千萬隻iPhone經由匿名的加密網路,傳送鄰近的Wi-Fi熱點與手機基地台資料給Apple而建立的。

 

  1. Is this crowd-sourced database stored on the iPhone?

The entire crowd-sourced database is too big to store on an iPhone, so we download an appropriate subset (cache) onto each iPhone. This cache is protected but not encrypted, and is backed up in iTunes whenever you back up your iPhone. The backup is encrypted or not, depending on the user settings in iTunes. The location data that researchers are seeing on the iPhone is not the past or present location of the iPhone, but rather the locations of Wi-Fi hotspots and cell towers surrounding the iPhone’s location, which can be more than one hundred miles away from the iPhone. We plan to cease backing up this cache in a software update coming soon (see Software Update section below).

4. 這個集體資料庫是儲存在iPhone上?

整個集體資料庫非常的大,無法儲存在iPhone上。因此我們會下載一個合適的子集合(暫存)到每支iPhone上。這個暫存檔案是受到保護的,但是並沒有加密,並且會在您使用iTunes備份您的手機時一併備份下來。此備份檔案是否加密,取決與使用者是否在iTunes中進行設定。

研究者們在iPhone中看到的定位資料並不是過去或是目前的iPhone位置,而是iPhone周圍的Wi-Fi熱點與手機基地台的位置,這些位置可能離您的iPhone超過一百英哩。

我們計畫在即將釋出的軟體更新中停止備份這些暫存資料。

 

  1. Can Apple locate me based on my geo-tagged Wi-Fi hotspot and cell tower data?

No. This data is sent to Apple in an anonymous and encrypted form. Apple cannot identify the source of this data.

5. Apple可以藉由我收集的Wi-Fi熱點與手機基地台資料來定位我的位置嗎?

不。這些資料是由匿名並加密的形式傳送到Apple。Apple無法辨識這些資料的來源。

 

  1. People have identified up to a year’s worth of location data being stored on the iPhone. Why does my iPhone need so much data in order to assist it in finding my location today?

This data is not the iPhone’s location data—it is a subset (cache) of the crowd-sourced Wi-Fi hotspot and cell tower database which is downloaded from Apple into the iPhone to assist the iPhone in rapidly and accurately calculating location. The reason the iPhone stores so much data is a bug we uncovered and plan to fix shortly (see Software Update section below). We don’t think the iPhone needs to store more than seven days of this data.

6. 人們發現長達一年的定位資料被儲存在iPhone內。為何我的iPhone只是為了找到我今天的位置,就需要如此多的資料?

這些資料並不是iPhone的定位資料,而是為了協助iPhone快速、精確地定位,而從Apple下載到iPhone,記錄Wi-FI熱點與手機基地台的集體資料庫中的一個子集合(暫存)。

iPhone會儲存如此多的數據,是由於我們之前沒有發現到的一個軟體錯誤。此錯誤計畫在近期內修正。(請見下方的軟體更新章節)我們認為iPhone不需要儲存超過七天份的資料。

 

  1. When I turn off Location Services, why does my iPhone sometimes continue updating its Wi-Fi and cell tower data from Apple’s crowd-sourced database?

It shouldn’t. This is a bug, which we plan to fix shortly (see Software Update section below).

7. 當我關閉定位服務時,為何我的iPhone有時會持續從Apple的Wi-Fi熱點與手機基地台資料庫更新資料?

這狀況其實並不應該發生。這是個軟體錯誤,我們計畫在近期修正它。(請見下方的軟體更新章節)

 

  1. What other location data is Apple collecting from the iPhone besides crowd-sourced Wi-Fi hotspot and cell tower data?

Apple is now collecting anonymous traffic data to build a crowd-sourced traffic database with the goal of providing iPhone users an improved traffic service in the next couple of years.

8.  除了Wi-Fi熱點與手機基地台資料之外,Apple有從iPhone中收集其他定位資料嗎?

Apple目前正在收集匿名的交通資料來建立集體資料庫,此資料庫的目標是在未來數年能提供iPhone使用者更先進的交通資訊服務。

 

  1. Does Apple currently provide any data collected from iPhones to third parties?

We provide anonymous crash logs from users that have opted in to third-party developers to help them debug their apps. Our iAds advertising system can use location as a factor in targeting ads. Location is not shared with any third party or ad unless the user explicitly approves giving the current location to the current ad (for example, to request the ad locate the Target store nearest them).

9. Apple目前是否有將iPhone收集到的任何資料提供給第三方?

我們將來自使用者的軟體當機記錄以匿名的方式提供給第三方軟體開發商,來幫助他們修正軟體的錯誤。我們的iAds廣告系統可以使用地理定位作為投放廣告的要素。

地理定位資訊並不與其他任何第三方共享,除非使用者明確地許可將目前的位置資訊傳送給目前顯示的廣告。(例如,要求廣告定位最接近他們的目標商店。)

 

  1. Does Apple believe that personal information security and privacy are important?

Yes, we strongly do. For example, iPhone was the first to ask users to give their permission for each and every app that wanted to use location. Apple will continue to be one of the leaders in strengthening personal information security and privacy.

10. Apple是否認為個人資訊安全與隱私是重要的?

是的,我們強烈地同意。例如,iPhone是第一台會在每個軟體每次想要使用定位資訊時,要求使用者給予許可的手機。Apple將會繼續成為加強個人資訊安全與隱私的領導者之一。

 

Software Update

Sometime in the next few weeks Apple will release a free iOS software update that:

未來幾週之內Apple將會釋出免費的iOS軟體更新:

In the next major iOS software release the cache will also be encrypted on the iPhone.

在下一個iOS的重大更新發佈時,在iPhone內的這些暫存資料將會被加密。
