Abstract

A method is provided for handling defined areas within an electronic document, which includes: marking at least one area in an electronic source document as indecomposable area which can be processed as a whole content only; generating signature data for the indecomposable area; assigning the signature data to the indecomposable area to create an indecomposable area object; storing the indecomposable object; encrypting and transmitting the indecomposable area object in response to a request of an enhanced content reader application, where the enhanced content reader application decrypts the indecomposable area object and processes the indecomposable area in an electronic target document; and generating and transmitting a protected version of the indecomposable area in response to a request of a regular content reader application, where the regular content reader application outputs the protected version of the indecomposable area in an electronic target document.
