How to avoid such problems?

Is there any way to avoid the original image being leaked?

First of all, we need to establish a sense of privacy protection in group chats with strangers.

Try not to post real photos.

Try not to check the original image when sending.

The WeChat team has also responded before

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 send the original photo via WeChat, SMS, email or other transmission tools, the attached information will be sent together. However, the photos sent in Moments are automatically compressed by the system and do not contain location and other information.

If you are really worried, you can avoid posting the original picture, or turn off the location. There is also a trick to kill it, edit the picture before posting it.

Anyway, the solution to the problem is simple:

①Avoid posting original images;

② If you really have to send it, turn off the location of your phone;

③The ultimate move: Photoshop
