Posting “Original Photos”Reveals Privacy?晒“原图”会暴露隐私吗？

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.

“一张照片能暴露多少隐私”成为新浪微博热门话题，这让大家关注起隐私问题并展开热烈讨论。

有些人会在群聊中发布自己的原图，但这可能会泄露其家庭地址和其他信息。

原图中往往包含大量的信息，以及数码相机或照片处理软件留下的各种痕迹。

这些数据被称为可交换图像文件格式（EXIF），对于许多专业人士来说，是至关重要的要素。EXIF能够详细显示拍摄者是否使用闪光灯、照片使用了哪些数码效果，以及照片拍摄于何时。据美国有线电视新闻网报道，EXIF甚至还能囊括照片拍摄地点的精确GPS坐标。

如果你在窗边拍了一张风景照片，然后将原图发送到群聊中，这意味着你正向群里所有的陌生人发布你的位置信息。他们甚至可以通过分析拍摄时间和角度，准确地推断出你所在的门牌号。

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，通过短信、电子邮件或其他传递工具发送图像，也会包含相应的信息。那么，在发送照片时，我们应如何保护自己的隐私呢？

保护隐私最有效的方法，是避免在群聊中发送原图。发布时尽量别点击“原图”。不过，微信团队表示，微信朋友圈发送的照片会被系统自动压缩，这些照片传播时不会附带位置等信息。

为了从根本上解决隐私暴露的问题，我们可以在计算机上删除图片的EXIF数据。如果你使用的是iOS智能手机，你可以在隐私设置中关闭摄像头的定位服务。如果你使用的是安卓智能手机，设置则有所不同。据加拿大电视台新闻报道，通常情况下，你可以打开设置菜单，关闭摄像头的服务。

你还可以这样来保护隐私——分享照片前先用编辑软件处理一下，编辑后的图像就不会存储位置数据了。
