According to the report, Professor Zhang of the school of computer engineering of Jiangsu ocean university said that when we turn on the GPS positioning of mobile phone, set the photo to save the geographical location and send the original picture, some information stored in the photo will be transmitted to each other together with the photo. Once the lawbreakers get the original pictures, they may locate or swindle the users according to the geographic location and other information contained in the pictures, which will bring disadvantages to the users.
At the same time, experts also give a way to avoid the pictures containing all kinds of sensitive personal information: users can choose to close the location information or not send the original photos.
In addition to sending the original picture carefully, wechat users can also protect their privacy through the following ways:
u00b7Turn off people nearby.
u00b7Turn off allow strangers to view photos.
u00b7Turn off the function of find you by QQ or mobile number.
u00b7Dont click the link at will.
u00b7Dont trust wechat friends to ask you for sensitive information.
u00b7Authorization requires no arbitrary permission.
