Ear prints as Potential evidence in criminal investigation: A Review

Abstract

When someone without permission does pre-intrusion activities like auditory surveillance close to a door or
window and has oils and waxes on their auricles, the deposition of a latent ear print may take place. By using
methods analogous to those used in fingerprint lifting processes, the visibility of this print can be increased. An
earprint is a 2D representation of the auricle segments that have come into contact with a certain surface, similar
to the impression left by a rubber stamp.
This study critically reviewed the efficacy of ear prints as a form of corroborative evidence and its significance
in the realm of personal identification. Ear prints, in conjunction with other latent evidence, have the potential to
be identified and gathered at the location of a criminal incident. The literature that has been examined exhibits
promising advancements and a notable level of precision in the field of ear print development and identification,
thereby emphasizing the necessity for further study.
