HOW TO DETECT A MODIFIED PDF FILE

Hi,

I worked with binary PDF structure  (I found that there is an ID key , it change when we update the PDF , but my problem still unsolved when we compress pdf (do the optimization : reduce file size , a new ID key ) so I’m searching if there is a solution or I should transformer pdf to image and maybe  with OCR  I will detect the fraud ?
