15. A scanning method for authenticating any laser image imprinted on a document comprising: a. illuminating any one surface of said document through an illumination source facing said surface; b. imaging opposite surface of said document wherein an illumination source facing the opposite surface is turned off; c. processing said imaging of opposite surface of said document in a data processor; said processing comprising i. detecting any laser image imprinted on said one surface of said document wherein said illumination source completely seeps through perforations of said laser image; ii. measuring amount of illumination source that seeps through perforations of said laser image; iii. contrasting said amount of seeped illumination source with a measured illumination source that seeped through perforations of reference laser image stored in said data processor.
