Patent ID: 8429397

Claim:
An information processing apparatus comprising: a processor; and a memory coupled to the processor storing instructions that, when executed by the processor, cause the processor to perform operations comprising: analyzing an electronic document generated using an application and generating first data in a markup language format comprising character codes and a first font specifying a relationship between the character codes and glyphs; and converting the first data into second data in the markup language format, wherein the converting converts the first data to the second data by: a) generating a second font specifying a relationship between character codes designated to be hidden and the glyphs based on a random code table and rearranging the character codes designated to be hidden so as to be displayed according to the second font with glyphs the same as the glyphs in the electronic document, b) generating a unique tag which is processible by a dedicated application but not processible by a general application and inserting the second font into the unique tag, and c) converting the first data into the second data comprising the rearranged character codes, the first font and the unique tag with the second font inserted; and providing the second data to a terminal device with an application being able to display data in the markup language format, wherein, in a case where the terminal device is equipped with the general application but not equipped with the dedicated application, the second font inserted in the unique tag is not referred and glyphs are identified based on the rearranged character codes according to the first font and when the terminal device is equipped with the dedicated application, glyphs are identified based on the rearranged character codes according to the second font inserted in the unique tag.
