How to test that a file ext is the same as the file type

I need to test for the circumstance where someone has renamed a TIF file with
a JPG extension. I have to process large number of image files that are
supposed all be JPG files. If I right-click on a file that is really a TIF,
windows can show in the properties that it is a TIF even though it has a JPG
extention. (In the properties window on the Summary tab under the Image node
for File Type the value is “Tagged Information File Format (TIFF)�

My questions are:
1- What is the technical term for this property?
2- How can I test for the condition where this property does not equal the
file extension in the file name?

I am running simple dos commands and a thumbnailer product via command line.
But I am open to more exotic methods.

Thanks in advance…

Thank you Shay,
EXIF is the term I was looking for and was guessing the powershell would be
the method, but I lacked some key information which you have pointed me to.
again, thank you.
