        Posting “Original Photos”Reveals Privacy?曬“原圖”會暴露隱私嗎?

        The topic “How much privacy can a photo reveal” has been trending on Sina Weibo, sparking concern and heated discussion about privacy awareness.

        In group chats, some people may post their original photos. But that may give away your home address and other information.

        Images often contain a lot of information and various traces left by digital cameras or photo manipulation software.

        This data, called Exchangeable Image File Format (EXIF), is a key tool for many professionals. It can detail whether the photographer used a flash, which digital effects were applied to a picture and when the photo was taken. EXIF can also contain the precise GPS coordinates of the location where a photo was taken, according to CNN.

        If you take a landscape picture from your window and send the original picture to a group chat, it means that you are releasing your location data to all strangers in the group. They may even accurately infer your house number by analyzing the shooting time and angle.

        “一張照片能暴露多少隱私”成為新浪微博熱門話題,這讓大家關注起隱私問題并展開熱烈討論。

        有些人會在群聊中發(fā)布自己的原圖,但這可能會泄露其家庭地址和其他信息。

        原圖中往往包含大量的信息,以及數(shù)碼相機或照片處理軟件留下的各種痕跡。

        這些數(shù)據(jù)被稱為可交換圖像文件格式(EXIF),對于許多專業(yè)人士來說,是至關重要的要素。EXIF能夠詳細顯示拍攝者是否使用閃光燈、照片使用了哪些數(shù)碼效果,以及照片拍攝于何時。據(jù)美國有線電視新聞網(wǎng)報道,EXIF甚至還能囊括照片拍攝地點的精確GPS坐標。

        如果你在窗邊拍了一張風景照片,然后將原圖發(fā)送到群聊中,這意味著你正向群里所有的陌生人發(fā)布你的位置信息。他們甚至可以通過分析拍攝時間和角度,準確地推斷出你所在的門牌號。

        Not just in a group chat, sending an image in a text message, email, or other delivery tools will also include the accompanying information. So how do we protect our privacy when sending photos?

        The most effective way is to avoid sending original photos in group chats. Try not to tap the “original picture”. However, photos sent by WeChat Moments are automatically compressed by the system, and they travel without location and other information, according to the WeChat team.

        To tackle the problem at its root, we can delete and remove a picture’s EXIF data on a computer. If you are using an iOS smartphone, you can turn off location services for the camera in the privacy settings. If you’re using an Android, the settings vary. Typically, you can go to the setting menu and switch the services off for the camera, according to CTV News.

        There is one more thing you can do— photoshop your photos before you share it. What comes with your edited images is photos without stored location data.

        不只限于群聊,通過短信、電子郵件或其他傳遞工具發(fā)送圖像,也會包含相應的信息。那么,在發(fā)送照片時,我們應如何保護自己的隱私呢?

        保護隱私最有效的方法,是避免在群聊中發(fā)送原圖。發(fā)布時盡量別點擊“原圖”。不過,微信團隊表示,微信朋友圈發(fā)送的照片會被系統(tǒng)自動壓縮,這些照片傳播時不會附帶位置等信息。

        為了從根本上解決隱私暴露的問題,我們可以在計算機上刪除圖片的EXIF數(shù)據(jù)。如果你使用的是iOS智能手機,你可以在隱私設置中關閉攝像頭的定位服務。如果你使用的是安卓智能手機,設置則有所不同。據(jù)加拿大電視臺新聞報道,通常情況下,你可以打開設置菜單,關閉攝像頭的服務。

        你還可以這樣來保護隱私——分享照片前先用編輯軟件處理一下,編輯后的圖像就不會存儲位置數(shù)據(jù)了。
