Abstract:
1. An information processing method comprising: a document data input step of inputting document data including a character string; an extraction step of recognizing characters in the input document data, and generating, on the basis of the result of the recognition, unique identification information associated with the input document data; a determination step of determining a position of an area at which the character string is located within the document data input in the document data input step, and generating position information representing the determined position; an image input step of inputting a predetermined image which is used as a background image of the document data; an embedding step of embedding, using a first parameter defining a robustness, the identification information generated in the extraction step, in an area of the input background image that corresponds to the position information determined in the determination step and embedding, using a second parameter defining a robustness, the identification information generated in the extraction step, in an area of the input background image other than the area corresponding to the position information determined in the determination step, wherein the first parameter has a higher strength than the second parameter; a composition step of compositing the background image embedded with identification information in the embedding step and the document data input in the document data input step; and an output step of outputting the document data composited in the composition step.
