A Comparative Case Study of Fingerprint Patterns in Male Convicts of Sabarmati Jail (ahmedabad) in Gujarati Population

There are numerous applications of fingerprints for human identification as they are unique and extensively used tool for identification of criminals during forensic investigations, in both civil and criminal cases. More elaborate studies are required with reference to ethnic and geographical variations in Gujarat which could be useful in creating a biometric database of fingerprints in which criminal history of convicts could also be included which will go a long way in supporting the criminal justice system and law enforcement agencies. Therefore the study was conducted on the convicts of Sabarmati jail to assess the patterns frequency in the fingertips of the criminals and their comparison with reference to normal Gujarati population (control). The study revealed that the convicts (male) had greater frequency of patterns than control (males) but statistically there was no association between the control and convict related to patterns in the respective digits. As seen from the p-value of the tests, we conclude that H1 is accepted i.e. there is association between right and left hand finger tip patterns in control males, convict males and their total also. Statistically it has also been found that there is no association between fingerprint patterns in both hands of convicts and control.
