If the first application itself is modified then it is likely that the image it acquired will also be modified. A subsequent determination may be made if the first application itself has not been modified.
And S2, uploading a second verification code related to the image after the first verification code is approved by the network system, so that the network system performs the first verification on the image by using the second verification code, wherein the second verification code includes characteristic information of the image.
