Abstract
Fingerprints have been utilized by forensic scientist to identify people present at a crime scene for almost 150 years. However, the fingerprints that are left behind can reveal maker's identity as well as the modus operandi. It is extremely difficult for a criminal to carry out his unlawful activity without leaving chance fingerprints but the difficult task is to develop and enhance that print on different surfaces to aid forensic investigation. The hardest task is to develop and enhance that print left on many surfaces to support forensic investigation. This paper will discuss the overview of laser application in fingerprint detection, detail its history and development, analyse the current technologies employed, as well as give insight into future developments. Finally, it will provide recommendations on the use and implementation of this technology in a range of security environments.
