Name at least two problems associated with the fingerprint method of biometric identification.
Q1. Explain briefly the importance of fingerprint analysis in Forensic science. One of the most important aspects of forensic science is examining fingerprints left at the scene of a crime. Usually, fingerprint analysis helps relate the crime to an individual who may have been present at the scene, but may also be used to monitor the past history of a person; convictions, parole, and other information. Q2. What are the characteristics of Latent fingerprints? The sweat and oil on the skin's surface are made up of latent fingerprints. In order to be seen, this sort of fingerprint is invisible to the naked eye and needs extra processing. Basic powder techniques or the use of chemicals may require this processing. Q3. Write the chemical reaction involved in Ninhydrin method. Mention the disadvantages of this method. Q4. Name some surfaces on which Iodine fuming method can be used for visualization of fingerprints. Q5. Enlist the limitations of fingerprint analysis Students sometimes get confused by the limitations of fingerprint research. There is no scientific way of knowing when a latent print was first deposited on a surface, for instance. Prints will live forever under the correct circumstances.
