Summary
Digital photography shows potential for lip print recording, but classification systems need calibration. Further research is essential for forensic applications and AI integration in biometric identification.
Area of Science:
- Forensic Science
- Biometrics
- Digital Imaging
Background:
- Direct digital photography for lip print recording is emerging.
- Limited research exists on analyzing digital lip prints with current classification systems.
Purpose of the Study:
- Compare digital photography accuracy for lip print recording against traditional methods.
- Assess suitability of standard lip print classifications for photographic recordings.
Main Methods:
- 72 participants (aged 20-26) were included.
- Lip prints recorded via digital photography (with/without lipstick) and cellophane tape.
- Statistical analysis compared print agreement across methods.
Main Results:
- High inter-observer reliability (>0.800) for all methods.
- Moderate agreement (kappa=0.449-0.517) between conventional and digital methods.
- Digital methods showed moderate agreement (kappa=0.718), with enhanced photos yielding higher positive agreement.
Conclusions:
- Digital photography is a viable method for lip print recording.
- Lip print classification systems require calibration for digital recordings.
- Further research needed for forensic use and AI integration in biometric identification.
