The purpose of this study is to examine Hangul signature changes of writers under the influence of alcohol using Scale for Handwriting Identification (SHWI). It has been recognized that handwriting is influenced by alcohol. However, in Korea, there has been no study which examined the handwriting changes after drinking alcohol. This study confirmed the differences between signatures in sobriety at police station (SIS) and signatures under the influence of alcohol at sobriety checkpoint (S-UIA) by analyzing the Hangul signature of 30 persons. The comparative characteristics are size, space, omission, writing order, connection. The changes of more than one characteristic were observed among the 27 out of 30 persons. Three of 30 persons did not show any change between S-IS and S-UIA.
