A Technique for Visualization of Latent Fingerprints Using Curcuma Longa (Turmeric) On Electronic Surfaces
Curcuma longa (Turmeric) is a rhizomatous herbaceous perennial plant of the ginger family Zingiberaceae. It has been cultivated in India from very ancient times. The rhizomes which yield turmeric are short and thick with blunt tubers. In this investigation a less expensive, simple and easily available, turmeric powder, a common ingredient in Indian food, has been used to take latent fingerprints on electronic surfaces .It is found that it gives very clear results in the majority of the surfaces.
The aim of the research is to find a new technique for the identification of latent fingerprints using Curcuma longa (Turmeric) on different surfaces like electronic surfaces .
Materials And Methods:
The plant powder was applied for visualisation of latent fingerprints on electronic surfaces like laptops, mobile phone,mobile phone charger, power bank, iPad, kettle and the observed fingerprints are analysed
It is suggested that the turmeric powder can be used to visualize the fingerprints particularly on the surfaces having contrast. Prints present on skin could not be developed clearly in comparison to others may be due to lack of contrast. These results suggest that turmeric powder can be successfully employed as a fingerprint powder on the majority of the surfaces.
It is concluded that turmeric powder which is easily available, non-toxic and simple can be used successfully on various surfaces to develop the prints in crime investigations.
