CHEILOSCOPY AND HIDDEN LIP PRINT ANALYSIS – A REVIEW

Abstract

Identification is important in any crime and forensic investigations. Lip print patterns are unique, like the fingerprints. Lip prints or Cheiloscopy is a forensic investigative method for person identification based on lip traces. Lip-print investigations have sparked the interest of many experts in recent decades as a novel technique for person identification in criminal and civil matters. Lip print evidence (LP) may be a valuable tool in human forensics. LPs have traditionally been created with indigo dye, lysochrome dyes, aluminium powder, fluorescent dyes, and silver metallic powder. In practice, methods and techniques for enhancing lip prints on various substrates remain inconsistent and lack standardization. Lip prints have often been seen in murders, burglaries and rape incidents. Since smart notorious criminals started taking precautions to avoid the possibility of leaving behind any fingerprints at the crime scene, the lip print has proven to be useful supporting evidence.
