????“蘋(píng)果（Apple）沒(méi)有跟蹤你的iPhone的位置,。蘋(píng)果過(guò)去沒(méi)有這樣做過(guò),，未來(lái)也不會(huì)?！?/p>

????上周三,，兩名英國(guó)研究者發(fā)布了一款開(kāi)源程序，通過(guò)該程序,，蘋(píng)果用戶能夠以彩色地圖的形式,，看見(jiàn)自己iPhone和3G iPad中存儲(chǔ)的位置數(shù)據(jù),，自那以來(lái)，關(guān)于“追蹤門(mén)”的爭(zhēng)議越來(lái)越大,。為此蘋(píng)果在針對(duì)此事件的新聞稿中做出了以上回應(yīng),。

????本周三，蘋(píng)果發(fā)布了一份新聞稿,，煞費(fèi)苦心地解釋蘋(píng)果具體在將哪些信息記錄和傳送回公司總部,，而沒(méi)有記錄和傳送哪些信息。

????新聞稿稱：“用戶之所以感到困惑,，一部分原因在于新技術(shù)的創(chuàng)造者（包括蘋(píng)果）沒(méi)有向他們提供足夠的與這些問(wèn)題相關(guān)的培訓(xùn),。”

????本著向用戶提供上述培訓(xùn)的精神,，蘋(píng)果用了好幾種方式解釋稱，這些顯示iPhone位置信息的地圖其實(shí)顯示的并不是你的iPhone真正的位置信息,。

????實(shí)際上,，iPhone會(huì)維護(hù)一個(gè)數(shù)據(jù)庫(kù)，以記錄你附近的Wi-Fi熱點(diǎn)和小區(qū)發(fā)射塔信息,，它們有些可能離你的iPhone超過(guò)100英里,。這些數(shù)據(jù)會(huì)幫助iPhone在需要時(shí)快速而精確地得到你的iPhone的地理位置信息。

????iPhone存儲(chǔ)了超過(guò)1年的地理信息數(shù)據(jù),，其原因被描述為“這是我們產(chǎn)品存在的缺陷,，我們計(jì)劃馬上修復(fù)該缺陷?！贝送?，即便你關(guān)閉了地理信息服務(wù)，數(shù)據(jù)收集仍在進(jìn)行,，這是蘋(píng)果計(jì)劃馬上修復(fù)的另一個(gè)缺陷,。

????為了避免將來(lái)遇到更多爭(zhēng)議，蘋(píng)果利用此次機(jī)會(huì)告訴客戶,，它還在收集和共享以下幾種信息：

????? 道路交通信息,，為了幾年之后發(fā)布更好的交通服務(wù)；

????? 崩潰記錄,，向第三方開(kāi)發(fā)者提供,，以幫助他們調(diào)試自己的應(yīng)用程序；

????? 如果你明確許可,，蘋(píng)果將與iAd的客戶共享你當(dāng)前的位置信息,，以幫助后者精準(zhǔn)投放廣告。

????以下是蘋(píng)果新聞稿的全文：

蘋(píng)果關(guān)于地理信息數(shù)據(jù)的問(wèn)答

????蘋(píng)果很高興回答最近收到的關(guān)于我們的設(shè)備收集和使用地理位置信息的問(wèn)題,。

????1.為什么蘋(píng)果跟蹤我的iPhone的位置,？

????蘋(píng)果沒(méi)有跟蹤你的iPhone的位置,。蘋(píng)果過(guò)去沒(méi)有，未來(lái)也不會(huì),。

????2. 那為什么大家都很關(guān)注此事,？

????為移動(dòng)用戶提供快速而精確的位置信息，同時(shí)確保他們的安全和隱私,，相關(guān)技術(shù)非常復(fù)雜,，很難用一兩句話說(shuō)清楚。用戶之所以感到困惑,，一部分原因在于新技術(shù)的創(chuàng)造者（包括蘋(píng)果）沒(méi)有向他們提供足夠的與這些問(wèn)題相關(guān)的培訓(xùn),。

????3. 為什么iPhone會(huì)記錄我的位置？

????iPhone沒(méi)有記錄你的位置,。iPhone會(huì)維護(hù)一個(gè)數(shù)據(jù)庫(kù),，以記錄你附近的Wi-Fi熱點(diǎn)和小區(qū)發(fā)射塔信息，它們有些可能離你的iPhone超過(guò)100英里,，這些數(shù)據(jù)會(huì)幫助iPhone在需要時(shí)快速而精確地得到你的iPhone的地理位置信息,。單獨(dú)使用GPS（全球定位系統(tǒng)）衛(wèi)星數(shù)據(jù)計(jì)算手機(jī)的位置要花費(fèi)好幾分鐘。而iPhone能利用Wi-Fi熱點(diǎn)和小區(qū)發(fā)射塔數(shù)據(jù)迅速發(fā)現(xiàn)GPS衛(wèi)星,，從而將定位時(shí)間縮短到幾十秒,。當(dāng)GPS不可用時(shí)（例如在室內(nèi)或地下室）,，iPhone甚至還能使用三角測(cè)量法,，僅僅依靠Wi-Fi熱點(diǎn)和小區(qū)發(fā)射塔數(shù)據(jù)計(jì)算出你的位置,。iPhone利用含有Wi-Fi熱點(diǎn)和小區(qū)發(fā)射塔數(shù)據(jù)的眾包數(shù)據(jù)庫(kù)（crowd-sourced database）進(jìn)行實(shí)時(shí)計(jì)算,，成千上萬(wàn)的iPhone會(huì)將自己附近的Wi-Fi熱點(diǎn)和小區(qū)發(fā)射塔信息打上地理標(biāo)簽,，并以匿名和加密格式發(fā)送給蘋(píng)果,。

????4. 眾包數(shù)據(jù)庫(kù)儲(chǔ)存在iPhone上嗎,？

????整個(gè)眾包數(shù)據(jù)庫(kù)太大,，不能存放在iPhone上,，所以我們?cè)诿坎縤Phone上下載了它的一個(gè)合適子集（即緩存）。這塊緩存是受保護(hù)的,，但沒(méi)有被加密,，當(dāng)你用iTunes備份iPhone時(shí)，緩存也會(huì)備份,。備份是否加密取決于用戶iTunes的設(shè)置,。研究者在iPhone上發(fā)現(xiàn)的地理信息數(shù)據(jù)并不是iPhone之前或現(xiàn)在的位置信息，而是iPhone周?chē)腤i-Fi熱點(diǎn)和小區(qū)發(fā)射塔數(shù)據(jù),，它們有些可能距離iPhone超過(guò)100英里,。我們計(jì)劃馬上發(fā)布軟件更新以停止緩存?zhèn)浞莨δ埽▍⒁?jiàn)接下來(lái)的軟件更新章節(jié)）。

????5. 蘋(píng)果能從我的帶有地理標(biāo)簽的Wi-Fi熱點(diǎn)和小區(qū)發(fā)射塔數(shù)據(jù)中獲得我的位置信息嗎,？

????不能,。發(fā)送給蘋(píng)果的數(shù)據(jù)是匿名而且加密的,。蘋(píng)果無(wú)法確定數(shù)據(jù)來(lái)源。

????6. 人們發(fā)現(xiàn)iPhone存儲(chǔ)了時(shí)間長(zhǎng)達(dá)1年的地理信息數(shù)據(jù),。為什么iPhone需要如此多的數(shù)據(jù)以幫助定位我的當(dāng)前位置,？

????這些數(shù)據(jù)不是iPhone的地理信息數(shù)據(jù)——它們是基于眾包的Wi-Fi熱點(diǎn)和小區(qū)發(fā)射塔數(shù)據(jù)庫(kù)的子集（即緩存），iPhone從蘋(píng)果下載了這些數(shù)據(jù)以幫助用戶快速而精確地定位,。iPhone存儲(chǔ)了如此多數(shù)據(jù)的原因在于我們的產(chǎn)品存在缺陷,，我們計(jì)劃馬上修復(fù)該缺陷（參見(jiàn)接下來(lái)的軟件更新章節(jié)）。我們認(rèn)為iPhone存儲(chǔ)的數(shù)據(jù)不應(yīng)該超過(guò)7天,。

????7. 為什么當(dāng)我關(guān)閉了地理信息服務(wù),，iPhone有時(shí)仍從蘋(píng)果的眾包數(shù)據(jù)庫(kù)里更新Wi-Fi熱點(diǎn)和小區(qū)發(fā)射塔數(shù)據(jù)。

????這種情況不應(yīng)該出現(xiàn),，這是產(chǎn)品缺陷,，我們計(jì)劃馬上修正（參見(jiàn)接下來(lái)的軟件更新章節(jié)）。

????8. 除了基于眾包的Wi-Fi熱點(diǎn)和小區(qū)發(fā)射塔數(shù)據(jù),，蘋(píng)果還收集了哪些地理信息數(shù)據(jù),？

????蘋(píng)果目前正在收集匿名交通數(shù)據(jù)，以建立基于眾包的交通數(shù)據(jù)庫(kù),。在未來(lái)幾年，蘋(píng)果將向iPhone用戶提供更好的交通服務(wù),。

????9. 蘋(píng)果目前向第三方提供了從iPhone收集的數(shù)據(jù)嗎,？

????我們會(huì)在獲得用戶允許的情況下，向第三方開(kāi)發(fā)者提供匿名的程序崩潰記錄,，以幫助他們調(diào)試自己的應(yīng)用程序,。我們的iAds廣告系統(tǒng)會(huì)利用地理信息作為投放廣告的一個(gè)依據(jù)。地理信息不會(huì)與任何第三方或廣告分享,，除非用戶明確同意將當(dāng)前的地理信息提交給當(dāng)前的廣告（例如用戶要求廣告定位離自己最近的目標(biāo)商場(chǎng)）,。

????10. 蘋(píng)果是否認(rèn)為個(gè)人信息的安全和隱私非常重要？

????當(dāng)然,，這非常重要,。例如，每一次應(yīng)用程序想使用地理信息時(shí),，iPhone都會(huì)要求用戶同意,，iPhone是第一款這樣做的設(shè)備。蘋(píng)果將繼續(xù)在鞏固個(gè)人信息安全和隱私方面充當(dāng)領(lǐng)導(dǎo)者角色,。

軟件更新

????接下來(lái)幾周內(nèi),，蘋(píng)果將為iOS軟件發(fā)布一個(gè)免費(fèi)升級(jí)：

????? 減少iPhone上緩存的眾包的Wi-Fi熱點(diǎn)和小區(qū)發(fā)射塔數(shù)據(jù)的體積；

????? 停止備份緩存,；

????? 當(dāng)?shù)乩硇畔⒎?wù)被關(guān)閉時(shí),，完全刪除緩存,。

????另外，在下一次iOS軟件的重大升級(jí)中,，iPhone上的緩存將被加密,。

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

????So begins Apple's (AAPL) response to the controversy that has been mounting since last Wednesday when two British researchers released an open source application that let Apple's customers see -- in the form of multicolor maps -- the location data stored on their iPhones and 3G iPads.

????In a press release issued Wednesday, the company took pains to explain exactly what data it is and isn't recording and transmitting back to headquarters.

????"Users are confused," it says, "partly because the creators of this new technology (including Apple) have not provided enough education about these issues to date."

????In the spirit of providing said education, Apple says in several different ways that the maps that show where your iPhone has been are not really maps of where your iPhone has been.

????Rather, [Apple is] 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.

????The fact that this location was being saved for more than a year is described as "a bug we uncovered and plan to fix shortly." The fact that it is being collected even when your location services are turned off is another bug they plan to fix shortly.

????Meanwhile, to get ahead of possible future controversies, Apple used this opportunity to tell customers what other kinds of information it is collecting and sharing:

????? road traffic information, with an eye to releasing improved traffic services in a couple years

????? crash logs, which it provides to third-party developers to help them debug their apps

????? your current location, which it shares, if you explicitly approve it, with iAd customers to help them target their pitches

????Below: The full text of the press release.

April 27, 2011

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.

????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.

????2. 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.

????3. 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.

????4. 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).

????5. 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.

????6. 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.

????7. 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).

????8. 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.

????9. 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).

????10. 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.

Software Update

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

????? reduces the size of the crowd-sourced Wi-Fi hotspot and cell tower database cached on the iPhone,

????? ceases backing up this cache, and

????? deletes this cache entirely when Location Services is turned off.

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