Tencent's wechat team pointed out that nowadays, any photo taken by a smartphone contains EXIF parameters, which can call GPS global positioning system data to record location, time and other information in the photo.Whether you use wechat, SMS, email or other transmission tools to send the original image, you will send the attached information together。
According to wechat, photos sent by friends' circle are automatically compressed by the system without information such as location.
For privacy concerns, wechat said that if you are really worried, you can avoid sending the original image or turning off the location.There's another way to kill. Send it after P completes the picture。

Nowadays, any photo taken by a smartphone contains EXIF parameters, which can call GPS global positioning system data to record location, time and other information in the photo.
When the user sends the original image to other people, the attached information is also sent. This is true whether you use wechat, SMS, email, or other transmission tools. Strictly speaking, the so-called geographical location information disclosure has nothing to do with wechat. Some public numbers attribute it to WeChat, which is seriously misleading, causing panic to the majority of users.
In addition, the pictures sent by the user in the circle of friends have been automatically compressed by the system, not the original pictures, and no location information.Some accounts claim。
We hope that public accounts can carefully identify information, avoid exaggerating the facts and cause unnecessary harm to the public and enterprises. We also remind users to pay attention to personal information protection, which can be used on smartphones.
