A Newer Technique Induced Latent Fingerprint Registration by Using Vetiveria Zizanioides Powder on Electronic Surfaces

Abstract

Introduction:

Most of the conventional methods make use of chemicals for registration of the latent fingerprints which causes potential health hazards to the examiner during the identification. Hence to overcome all these disadvantages the researchers have worked on the development of latent fingerprints using powders of herbal origin. Vetiveria zizanioides is commonly known as Khas Khas, Khas, or Khus grass in India. It belongs to the Poaceae family. Its major constituents are vetiselinenol and khusimol, which render the herb its pharmacological properties. The present study aims to use a new fingerprint powder with herbal formulation using Vetiveria zizanioides.

Aim:

To use a new fingerprint powder with herbal formulation using Vetiveria zizanioides for latent fingerprints registration on electronic surfaces.

Materials And Method:

Vetiveria zizanioides was dried for 7 days and after that, it was dried in shade for 3 days. The plant was then powdered and was used to obtain latent fingerprints by dusting it on various electronic surfaces.

Results And Discussion:

The results obtained in the present study are in accordance with many other scientists who worked on the development of latent fingerprints using different powders. Fuller’s Earth for the development and visualization of latent fingermarks present on the different matrix was done successfully by pallavi thakur et al. Garg et al demonstrated the use of turmeric powder obtained from rhizomatous herb on nine different surfaces and it gave clear development on the majority of surfaces.

Conclusion:

It can be concluded that the Vetiveria zizanioides powder gave a clear development of the latent fingerprints on different electronic surfaces and possesses good properties of a latent fingerprint powder and also it is organic, cheap, and non-toxic.
