Sex identification based on lipprint patterns: A Review
Keywords:Crime; crime scene; lip-print; lip-print pattern; lip-print type; sex identification.
Background: Many researchers have conducted studies oflip prints to aid in human identification. The
distinctiveness of the lip print pattern will be a distinguishing feature from one person to the next.
Purpose: This study analyzes the dominant types and patterns of lips print in males and females.
Results: Most males--7 research out of 20--were type III lip print pattern, and 6 out of 20 belong to the type II lip
print pattern. Femalesmainly were typed II pattern—11 out of 20, and type I pattern—7 out of 20.
Conclusion: When the patterns are type I or type III, the sex of the individual can be easily identified; however,
when the pattern is type II, the individual could be either a male or a female, with a higher probability of being a
female. Other forms of identification should be available to support sex identification in this circumstance.
