Abstract: In the field of forensic science,identification of earprints is a new and interesting topic for many forensic examiners.Three issues related to earprints are reported.The first is about visualization of earprints,including ways of developing,the relationship between developing time and the effect,the relationship between surfaces and the effect,and the method of collecting.The second is about personal identification.The scientificity of earprint identification is discussed on the basis of a small range experiment of earprints.Besides,the procedure,method and criterion of earprint identification are also introduced.The third issue is concerned with how to deduce one's height from his earprint left at the crime scene.Through experimental statistics,we try to find a formula that establishes the relationship between a person's height and the height of his earprints.

Key words: earprint, developing and collecting, height inference, personal identification
