DATA DISPLAY SYSTEM AND METHOD AND DEVICE FOR DATA DISPLAY

摘要

PROBLEM TO BE SOLVED: To prevent the illegal use of picture contents from which visual additional information is removed. SOLUTION: Visible marking picture data embedded with a sent visible mark is stored in a picture storage 200, and a marking 202 removes the visible mark from this visible marking picture and simultaneously embeds it with an invisible mark in parallel by integrated indivisible processing to generate invisible marking data which is not visually different from original picture data. A fragment picture generation part 206 generates n kinds of fragment picture data which look like the original picture by alternative display in spite of individual partial change. A picture display 212 displays these fragment picture data at intervals of a time Ti to show them to a user as sample picture data.
