The identification of an entity is the recognition of any person based on his/her physical peculiarities. Individualization is necessary often in a multitude of conditions such as social recognition, criminal identification, and mass catastrophe. The suggested study hereby investigates the preponderance in the pattern of lip print, fingerprint and blood grouping and to strike out if there is any interaction between the three variables. The study was directed on 200 individuals, of which 100 were males and 100 were females, originally belonging to the Bundelkhand region of Uttar Pradesh. The sample for lip prints was solicited and later interpreted on the assumption of classification of lip prints given by Suzuki and Tsuchihashi. Karl Landsteiner classification approach was retained for blood grouping and thumb impression was drawn to inspect the fingerprint pattern which was further scrutinized according to Henry Fingerprint Classification System. For the statistical analysis, frequency distribution and percentage method were used for descriptive statistics, whereas for inferential statistics chi-square and Pearson correlation coefficient were applied. The present study concludes that the type II lip print pattern was common in both males and females. Type III is the second most predominant pattern in male whereas in females it is type I. Considering the second variable of the study that is blood group, B+ is common in entire sample size while O+ shows predominance in males wherein females B+ is common. Loop pattern in both the sexes is common among the individuals of Bundelkhand region. The statistical result for chi-square shows that there is no significant association between the variable gender with that of lip print, blood group, and fingerprints. The result of correlation coefficient exhibits that there is a statistically significant relationship between blood groups and fingerprints. There is a substantial correlation coefficient between blood groups and fingerprints patterns of the individuals of an enumerated state.
