社交網站社交功能減弱 用戶隱私設置加強大綱

Users of online social network sites such as Facebook are editing their pages and tightening their privacy settings to protect their reputations in the age of digital sharing, according to a new survey。

About two-thirds, or 63 percent, of social networking site (SNS) users questioned in the Pew Research Center poll said they had deleted people from their "friends" lists, up from 56 percent in 2009.

Another 44 percent said they had deleted comments that others have made on their profiles, up from 36 percent two years before。

Users also have become more likely to remove their names from photos that were tagged to identify them. Thirty-seven percent of profile owners have done that, up from 30 percent in 2009, the survey showed。

"Over time, as social networking sites have become a mainstream communications channel in everyday life, profile owners have become more active managers of their profiles and the content that is posted by others in their networks," the report said。

The Pew report also touches on the privacy settings people use for their SNS profiles. The issue of online privacy has drawn increasing concerns from consumers, and the Obama administration has called for a "privacy bill of rights" that would give users more control over their data。

Fifty-eight percent of those surveyed said their main profile was set to be private so that only friends can see it。

Another 19 percent said they had set their profile to partially private so that friends of friends can see it. Only 20 percent have made their profile completely public。

The report was based on telephone survey of 2,277 adults in April and May 2011 as part of Pew's project on the Internet and American life。一項新調查顯示，Facebook等社交網站的用戶爲了在數據分享時代保護自己的名譽，正在編輯自己的頁面、加強隱私設置。

皮尤調查中心的這一民意調查訪問的社交網站用戶中，約有三分之二(63%)稱他們刪除了自己的部分“好友”，而在2009年這一比例僅爲56%。

此外，刪除他人在個人主頁上的留言的人佔了44%，相比兩年前的36%上升了。

調查顯示，還有更多用戶去掉了圖片上可以識別出自己的署名。這麼做的用戶有37%，相比2009年的30%增加了。

該報告稱：“隨着時間的推移，社交網站已成爲日常生活的主流溝通渠道，如今社交網站用戶更主動地去管理自己的個人主頁和他人發佈在自己網頁上的內容。”

皮尤的這一調查報告還涉及了人們對社交網絡個人主頁的隱私設置。現在網絡隱私問題越來越爲消費者所關注，奧巴馬政府呼籲通過“隱私權法案”，這一法案將給用戶更多對個人資料的控制權。

58%的被調查者稱自己把個人主頁加密，只有好友能看到內容。

另外有19%的人稱他們把個人主頁設爲部分加密，讓好友的好友也能看到。只有20%的人的個人主頁對所有人開放。

這一報告基於2011年四月和五月期間對2277名成人的電話調查，是皮尤網絡和美國生活調查項目的一部分。
