The Wikipedia page didn't seem to mention other similar systems created historically to impede modification/miscomprehension. China has a separate set of accounting number glyphs specifically for this purpose, as the regular numbers 1-9, 100, 1,000 and 10,000 (一二三四五六七八九十百千萬) are obviously easy to change, for example 一 to 十 or 千, 二 to 三, 八 to 九, etc. The replacements are 壹貳參肆伍陸柒捌玖拾佰仟萬.
