A New Technique for visualisation of latent fingerprints in walls, floors and doors using Lodhra bark (Symplocos Racemosa). Type of article: Original study
Abstract
INTRODUCTION: A fingerprint is an impression made by the frictional ridges of the finger. Whenever We touch things (like a coffee cup, a door, a keyboard, remotes, mobile-phones, etc.,) we leave our fingerprints on that object or surface. It is like that we leave our unique birth signature in our fingerprints1. Just like our signature fingerprints are also unique for everyone. No two people in the world share exactly the same fingerprint. Even identical twins, who have identical DNA in them, don’t have the same fingerprint. This uniqueness allows fingerprints to be used in all sorts of ways, including for personal identification cards, biometric systems, mass disaster identification, in criminal scenes.No challenges are faced in the previous novel researches This research is needed to develop a new technique for identification of latent fingerprints. This research also fulfills the deficiency of work on identification of aged latent fingerprints.The aim of this study is to find a new technique for visualisation and analysis of latent fingerprints using Lodhra Bark powder on different surfaces like walls, floors and doors.It is a retrospective study. Novel products are used in this research. This research should be continued to trials
AIM: The aim of this research is to find a new technique for visualising the latent fingerprints
MATERIALS AND METHODS: The sample is taken in powder form. Based on the previous research work articles will be collected and the work be carried out accordingly. Lodhra bark is collected and dried for 7 days. After that it was kept in the shade dry for 3 days. Then it is made into powder form.
RESULTS: Then using the powder fingerprint dusting is done. Randomly selected 15 people are asked to make finger impressions on the walls, doors and floors. Then using the prepared Lodhra bark powder those fingerprints are dusted.
CONCLUSION:Thus, from the above research, we can get the visible fingerprints using lodhra bark powder but the fingerprints that are developed using lodhra bark powder do have enough properties to get fine well defined prints which can be used as a valuable tool to identify the
suspect and for law enforcement. And this lodhra bark powder is cheaper and easily available than other powders which are currently used for dusting. It is also non allergic and non toxic. KEYWORDS: latent prints,Innovative technique, Lodhra bark powder, Novel method.
Running title: A new method for visualizing the latent fingerprints using Lodhra bark (Symplocos Racemosa) in walls, floors, and doors
