Abstract:
The present invention discloses a method and a device for generating an associated image file and a method and a device for verifying an image. The method for generating an associated image file comprises: scanning an object under inspection to obtain first image volume data and second image volume data associated with each other; creating a first image file at a first time point on the basis of the first image volume data; generating a random time value; and generating a second image file associated with the first image file at a second time point on the basis of the second image volume data, wherein the random time value is recorded in a file header of the second image file. The above technical solution enhances security during an image determination process and is capable of discovering a false security image substituting a real security image.
