Will the original picture reveal privacy?

1. It is true that the original photo reveals privacy. If we download the original photos sent by WeChat friends to the mobile phone, and then view them through the mobile phone album, we can see the shooting time, mobile phone model and even the shooting location. However, if the original image is not sent, the location information cannot be viewed.

2.02 Why does sending the original image reveal information? In fact, there is a group in every digital photo. Interchangeable image file format? Information, Exif for short. This set of information is equivalent to the digital ID card of the photo, which can record the attributes and shooting data of the digital photo. For example, if you shoot a landscape map in your window and send the original map to the group, it is equivalent to publishing the GPS location data of your home to all strangers in the group. Even by analyzing the shooting time and shooting angle, you may accurately infer the floor and house number of your home. Similarly, the original picture sent by SMS or email can also expose this information.
