Abstract

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.

Abstract

In this study an attempt has been made to correlate the age and the angles of triradius along with the gender variation in angles. It was found that there was no significant difference between atd angles between male and female and there was significant difference between male and female in dat and adt angles. On the other hand the correlation study of angle with age between male and female indicated strong positive correlation for angle adt, weak positive correlation for angle atd and strong negative correlation for dat angle. Thus neither age nor angle is the reason for increasing or decreasing the value of other as correlation does not mean causation
