Google Flu Trends tool raises privacy concerns谷歌工具流感趨勢引起隱私擔憂 Wednesday, December 10th, 2008 星期三, 2008年12月十日
Privacy groups want Google to ensure that aggregate search data about flu outbreaks cannot be used to re-identify the people who provided the information隱私保護組織希望谷歌,以確保匯總數據搜索感疫情不能用來重新識別人誰提供的信息Google’s new Flu Trends tool, which collects and analyzes search queries to predict flu outbreaks around the country, is raising concern with privacy groups.谷歌的新流感趨勢的工具,收集和分析查詢預測感疫情在全國各地,是提高關注隱私的群體。 The Electronic Privacy Information Center filed a Freedom of Information Act (FOIA) request asking federal officials to disclose how much user search data the company has recently transmitted to the Centers for Disease Control and Prevention, or CDC, as part of its電子隱私信息中心提出了信息自由法( FOIA )的要求,要求聯邦政府官員透露有多少用戶的搜索數據公司最近已轉交中心疾病控制與預防,或疾病控制和預防中心的一部分,其 Google Flu Trends effort 谷歌趨勢的努力,禽流感 . 。 [ Learn how to secure your systems with Roger Grimes' [了解如何保護您的系統與羅傑格里姆斯' Security Adviser blog 安全顧問博客 and 和 newsletter 簡訊 , both from InfoWorld. 都來自InfoWorld的。 ] ] Concern stems from what privacy groups claim is a disturbing lack of transparency surrounding the method Google is using to predict flu outbreaks.關注源於什麼隱私團體聲稱是一個令人不安的缺乏透明度,周圍的方法是使用谷歌預測感疫情。 Google has publicly stated 谷歌已經公開宣稱 that all of the data used is made anonymous and aggregated, but there has been no independent verification of how search queries are used and transformed into data for Google Flu Trends, the privacy groups say.所有使用的數據是匿名和匯總,但一直沒有獨立的核查如何查詢的使用和轉化成數據,谷歌流感趨勢,隱私團體說。 “What we are basically saying is that if Google has found a way to ensure that aggregate search data cannot be used to re-identify the people who provided the search information, they should be transparent about that technique,” said Marc Rotenberg, Electronic Privacy Information Center’s president.他說: “我們基本上都是要說的是,如果谷歌已找到一種方法,以確保總搜索數據不能被用來重新確定誰的人提供了搜索信息,他們應該是透明的這種技術說, ”馬克羅滕貝格,電子隱私信息中心的總裁。 Rotenberg said the issue is important because the same techniques Google is using to predict flu outbreaks could be applied to tracking other diseases, including those that the urgency to contain the disease could be a whole lot greater with, such as SARS.羅滕貝格說,這個問題是重要的,因為同樣的技術,谷歌正在利用預測感疫情可用於跟踪其他疾病,包括那些迫切需要遏制這一疾病可能是一大堆更大的,如嚴重急性呼吸系統綜合症。 “Let’s say we have a spike in Detroit of SARS and the police say we want to know who in Detroit submitted those searches. “讓我們說,我們有一個扣球在底特律的SARS和警察說,我們想知道誰在底特律提交的這些搜索。 How can Google ensure that this can’t be done?谷歌如何才能確保這種不能做? The burden is on Google,” Rotenberg said.負擔是谷歌“羅滕貝格說。 Google Flu Trends was publicly disclosed in November and has been described by the company as Web tool to help individuals and health care professionals obtain influenza-related activity estimates for all US states up to two weeks faster than traditional government disease surveillance systems.谷歌流感趨勢是公開披露的11月,並已描述了公司的網絡工具來幫助個人和健康護理專業人員獲得流感有關的活動估計為所有美國各州長達兩週速度比傳統的政府疾病監測系統。 Google said in a blog post introducing Flu Trends 谷歌表示,在博客中介紹了流感趨勢 last month that search queries such as “flu symptoms” tend to be very common during flu season each year.上個月,搜索查詢,如“流感症狀”往往是非常常見的流感季節期間每年。 A comparison of the number of such queries with the actual number of people reporting flu-like symptoms shows a very close relationship, it said.的比較多的,例如查詢與實際人數的報告類似流感的症狀顯示了非常密切的關係,它說。 As a result, tallying each day’s flu-related searches in a particular geography allows the company to estimate how many people have a flu-like illness in that region.因此,清點每一天的禽流感相關的搜索在特定地理使該公司估計有多少人有類似流感的疾病在該地區。 In making the announcement, Google noted that it had shared results from Flu Trends with the Epidemiology and Prevention Branch of the Influenza Division at CDC during the last flu season and noticed a strong correlation between its own estimates and CDC’s surveillance data based on actual reported cases.在作出這一宣布,谷歌指出,它已共享成果感發展趨勢與流行病學與預防流行性感冒司中華網在過去的流感季節,並注意到一個強有力的關係自己的估計和CDC的監測數據根據實際報告的案件。 Google said that by making flu estimates available each day, Google Flu Trends could provide epidemiologists with an early-warning system for flu outbreaks.谷歌說,禽流感,使現有的估計,每天流感趨勢谷歌可提供流行病學與預警系統的感疫情。 Rotenberg said the service was potentially useful, but much depended on the kind of search data that Google is collecting and analyzing to make its predictions.羅滕貝格表示,這項服務是潛在有用的,但很大程度上取決於什麼樣的搜索數據,谷歌是收集和分析作出的預測。 Google has said that the database it uses for Flu Trends retains no identity information, IP addresses or any physical user locations.谷歌曾表示,它使用數據庫的流感趨勢仍然沒有身份證信息, IP地址或任何身體用戶的位置。 However, what is not clear is whether the company is completely deleting IP addresses, and if so, when it is doing it.但是,什麼是不明確的是該公司是否完全刪除的IP地址,如果是的話,當它這樣做。 Also, he said another issue was whether all Google is doing is anonymizing IP addresses by redacting some of the numbers in an IP string.此外,他說的另一個問題是,是否所有谷歌這樣做,就是匿名IP地址的redacting一些號碼的IP字符串。 Google also claims that as part of its overall privacy policy it anonymizes all IP addresses associated with searches after nine months.谷歌還聲稱,作為其整體隱私權政策anonymizes所有IP地址與搜索後9個月。 Yet in an apparent contradiction, when introducing Flu Trends, Google noted that it uses both current and historic search data - dating back to 2003 — to make its predictions, Rotenberg said.然而,在一個明顯的矛盾時,介紹了禽流感的趨勢,谷歌指出,它採用了當前和歷史搜索數據-可追溯到2 003年-作出自己的預測,羅滕貝格說。 Jeffery Chester, executive director of the Center For Digital Democracy, said Google’s杰弗裡切斯特,執行董事,數字民主中心,說,谷歌的 growing presence in the healthcare space 越來越多的醫療空間 also makes it important for the company to disclose what kind of data it is collecting and using for Flu Trends.也使得它重要的是,公司披露什麼樣的數據是收集和使用的流感趨勢。 “Google sees a potential profit center from targeting its vast user base with advertising that is related to health issues,” Chester said. “谷歌看到了潛在的利潤中心從針對其龐大的用戶群與廣告相關的健康問題, ”切斯特說。 The company’s announcement of Flu Trends in fact shows to pharmaceutical and medical markets precisely the kind of sophisticated analysis the company can do with search data to enable highly targeted medical marketing, he said.該公司宣布的流感趨勢的事實表明,以藥品和醫療市場的恰恰是一種精密的分析,公司可以做的搜索數據,以便針對性很強的醫療市場,他說。 “This is about taking the tracking data that Google has at its disposal and focusing it on generating a new profit center for the company,” Chester said. “這是考慮的跟踪數據,谷歌已經在其處置和注重創造一個新的利潤中心的公司, ”切斯特說。 Pam Dixon, executive director of the World Privacy Forum, echoed similar concerns and questioned whether the anonymization techniques used by Google provided enough of a guarantee that a search term could not be traced back to specific individuals.帕姆迪克遜,執行董事的世界隱私論壇,呼應了類似的關注,並詢問是否匿名者所用技術谷歌提供足夠的保證搜索字詞不能追溯到具體的個人。 She pointed to an incident two years ago where她指出,事件兩年前在那裡 AOL inadvertently posted search information AOL的無意中張貼搜索信息 on a public Web site.在一個公共網站。 The search queries had supposedly been anonymized by AOL, but it was still relatively easy to track specific search terms back to IP addresses and even individuals in many cases, Dixon said.該查詢已被匿名理應由AOL ,但它仍然相對容易追踪特定的搜索條件返回的IP地址,甚至個人在許多情況下,迪克森說。 Mike Yang, senior product counsel at Google, downplayed privacy concerns related to Flu Trends and insisted that the tool uses no personally identifiable data.邁克陽,高級產品律師谷歌低調隱私問題有關的流感趨勢和堅持,工具使用任何個人身份資料。 “Flu Trends uses aggregated data from hundreds of millions of searches over time,” Yang said today in an e-mail. “流感趨勢使用匯總數據由數以億計的搜索隨著時間的推移, ”楊說,今天在一封電子郵件。 “Flu Trends uses aggregations of search query data which contain no information that can identify users personally. “流感趨勢的使用匯總數據搜索查詢包含任何信息,它可以識別用戶的個人。 We also never reveal how many users are searching for particular queries.”我們也從來沒有透露有多少用戶正在尋找特定的查詢。 “ Yang noted that the data used in Flu Trends comes from Google’s standard search logs.楊潔篪指出,所使用的數據在流感趨勢來自谷歌的標準搜尋記錄。 He also referenced他還引用 an article in the journal Nature 文章在自然雜誌 , authored by the Google Flu Trends team, which he said explains the methodology behind the tool. ,作者的谷歌團隊流感趨勢,這說明他說的方法背後的工具。 Have Your Say: Google Flu Trends tool raises privacy concerns 你說:谷歌工具流感趨勢引起隱私擔憂 Please read our請仔細閱讀我們的 posting guidelines before posting張貼在發布前的指導方針 . 。 Alternatively或者 you can discuss this report here你可以討論這份報告在這裡 . 。 Related News 相關新聞
