1. A method for comparing content of two document files each having a plurality of content blocks, the method to be implemented by an electronic device and comprising the steps of:
a) performing, for each of the content blocks in each of the document files, a pre-process operation so as to obtain a plurality of properties associated with the content block;
b) comparing, for each content block from one of the document files, the properties of the content block with the properties of each of the plurality of content blocks of the other one of the document files;
c) generating a comparison result based on the operations of step b);
d) receiving the two document files; and
e) in response to receipt of the two document files, identifying, for each of the document files, the plurality of content blocks.
